Company A offers a $35,000 annual salary plus a 6% commission of his total sales. Company B offers a flat annual salary of $36,000.How much would you need to have in total sales to earn the same amount in each job?

Answers

Answer 1

Answer: you need to have in total sales of $16667 to earn the same amount in each job

Step-by-step explanation:

Let x represent the amount that you need to have in total sales in order to earn the same amount in each job.

Company A offers a $35,000 annual salary plus a 6% commission of his total sales. This means that the total amount earned with company A when x sales is made yearly would be

35000 + 0.06x

Company B offers a flat annual salary of $36,000. This means that the total amount earned with company B yearly would be

36000

To earn the same amount with both jobs,

35000 + 0.06x = 36000

0.06x = 36000 - 35000

0.06x = 1000

x = 1000/0.06 = $16667

In a sheet metal operation, three identical notches and four identical bends are required. If the operations can be done in any order, how many different possible sequences are there to complete the manufacturing?

Answers

Final answer:

The problem can be solved using combinatorics, specifically the permutation of a multiset. Using the formula P(n; n1, n2, ..., nk) = n! / (n1! * n2! *...* nk!), where n is total number of operations and n1, n2,... are the number of each identical operation, the number of different possible sequences to complete the manufacturing operation are 35.

Explanation:

The number of sequences of the operations can be found by using the formula for permutations of multiset - a concept in combinatorics part of mathematics. Permutations of a multiset are the number of ways in which we can arrange all the elements of the multiset considering the repetition of elements. We have 7 operations in total: three identical notches (type A) and four identical bends (type B). The formula is:

P(n; n1, n2, ..., nk) = n! / (n1! * n2! *...* nk!), where n is the total number of items(7 in this case), n1,n2,...,nk are the number of each type of item.

Therefore, the number of different possible sequences to complete the manufacturing is: P(7 ; 3, 4) = 7! / (3! * 4!). This evaluates to 35.

William cycles at a sped of 15 miles per hour. He cycles 12 miles from home to school. If he increases his cycling speed ny 5 miles per hour how much faster will he arrive his school

Answers

Answer:he would arrive 0.2 miles faster.

Step-by-step explanation:

Distance = speed × time

Time = distance/speed

William cycles at a sped of 15 miles per hour. He cycles 12 miles from home to school. This means that the time it takes William to get to school from home would be

12/15 = 0.8 hours

If he increases his cycling speed by 5 miles per hour, his new speed becomes

15 + 5 = 20 miles per hour

Therefore, the new time it takes William to get to school from home would be

12/20 = 0.6 hours

The difference in both times is

0.8 - 0.6 = 0.2 hours

Therefore, he would arrive 0.2 miles faster.

A.) sec ^2 0
B.) -cos ^2 0
C.) -tan ^2 0
D.) 0
E.) 1

Answers

Answer:

E.) 1

Step-by-step explanation:

Firstly we will solve for L.H.S.

L.H.S. =[tex]Csc^2\theta[/tex]

Since we know that [tex]Csc^2\theta[/tex] is the inverse of [tex]Sin^2\theta[/tex].

So we can say that;

[tex]csc^2\theta=\frac{1}{sin^2\theta}[/tex]

Now For R.H.S.

[tex]Cot^2\theta+1[/tex]

Since we  can rewrite [tex]cot^2\theta[/tex] as [tex]\frac{cos^2\theta}{sin^2\theta}[/tex].

Now we can say that the R.H.S. is;

[tex]\frac{cos^2\theta}{sin^2\theta}+1[/tex]

Now we add the fraction and get;

[tex]\frac{cos^2\theta+sin^2\theta}{sin^2\theta}[/tex]

Now according to trigonometric identity;

[tex]cos^2\theta+sin^2\theta=1[/tex]

So, [tex]\frac{cos^2\theta+sin^2\theta}{sin^2\theta}=\frac{1}{sin^2\theta}[/tex]

Here,

[tex]csc^2\theta=\frac{1}{sin^2\theta}[/tex]   and     [tex]Cot^2\theta+1[/tex] = [tex]\frac{1}{sin^2\theta}[/tex]  

L.H.S. = R.H.S.

Hence [tex]csc^2\theta=cot^2\theta+1[/tex]

You deposited $10,000 into a savings account at 6%. After a certain amount of time, you earned $4,800. How long did you have your money in the savings account?

Answers

Answer:

800 months

Step-by-step explanation:

The formula for interest is:

(Capital * saving account * time) / 100

So:

(10000 * 0.06 * x) / (100) = 4800

We clear x:

(10000 * 0.06 * x) = (100) * 4800

x = 480,000 / (10000 * 0.06)

x = 800 months (66.67 years)

Final answer:

To determine the duration for which the deposited $10,000 at 6% interest grew to a total of $14,800 ($10,000 principal + $4,800 interest), the formula for compound interest can be re-arranged to solve for the time variable. You'll use the amount of money accumulated, the principal amount, the annual interest rate, and the assumption that the interest is compounded annually. Plug these values into the formula to calculate the number of years.

Explanation:

You deposited $10,000 into a savings account at 6% interest. To determine how long it took for you to earn $4,800 in interest, we can use the formula for compound interest, which is A = P(1 + r/n)^(nt), where:

A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for, in years.

In this case, we can rearrange the formula to solve for t, because you want to find out how many years it took for your investment to turn into A = $10,000 + $4,800 = $14,800. Assuming the interest is compounded annually (n = 1), the formula becomes:

t = ln(A/P) / n * ln(1 + r/n)

Plugging in the numbers gives us:

t = ln($14,800 / $10,000) / ln(1 + 0.06)

By calculating this, you can get the number of years you had the money in the savings account.

Imogene's car travels 294 mi averaging a certain speed. If the car had gone 7 mph faster, the trip would have taken 1 hour less. Find the average speed

Answers

Answer:

 42 mph

Step-by-step explanation:

If you start with the assumption that the answer is an integer, you can solve a problem like this by looking at the factors of 294.

  294 = 2·3·7² = 6·49 = 7·42

At 42 mph, the 294-mile trip took ...

   time = distance/speed = 294 mi/(42 mi/h) = 7 h

At a speed 7 mph faster, the 294-mile trip took ...

   (294 mi)/(49 mi/h) = 6 h . . . . . 1 hour less

The average speed of Imogene's car for the 294-mile trip was 42 miles per hour.

_____

Alternative solution

If you let s represent Imogene's speed, you can use the above time and distance relationship to write an equation relating the trip times:

  294/s = 294/(s+7) +1

Multiplying by s(s+7), we get ...

  294(s+7) = 294s +s(s+7)

  2058 = s^2 +7s . . . . . . . . . . . subtract 294s

We can complete the square by adding (7/2)^2 = 12.25 to both sides

  2070.25 = s^2 +7s +12.25 = (s +3.5)^2

  ±45.5 = s +3.5 . . . . . take the square root; next subtract 3.5

  -3.5 +45.5 = s = 42 . . . . use the positive solution

Imogene's average speed was 42 mph.

Final answer:

Imogene's average speed was 294 mph. We solve this by using the relationship between distance, speed, and time, and applying it to the specific constraints of the problem. By setting s = speed, we use two equations representing each scenario and solve for s.

Explanation:

Let's assign 's' to Imogene's average speed for the trip. The time taken at this speed is the distance traveled (294 mi) divided by 's' (speed = distance/time), making the time = 294/s. If the car was faster by 7 mph, the speed would be s+7 mph, and the time taken would then be 294/(s+7). The problem states that the second scenario would take 1 hour less, so 294/s = 294/(s+7) + 1.

Cross-multiplication and simplification of this equation result in (294s + 2058) = 294(s +7) or 294s + 2058 = 294s + 2058, which simplifies to 2058 = 7s, or s = 294 mph. Therefore, Imogene's average speed was 294 mph.

Albert went shopping with half of his monthly allowance. He spent $35.50 on a shirt and 3/5 of the remainder on a book. He had $25.80 left after his shopping trip. What was Albert's monthly allowance?

Answers

Answer:

$ 213.50

Step-by-step explanation:

From the question;

Albert spent;

$35.5 on a shirt 3/5 on the remainder on a book Remainder is $25.80

We are required to determine Albert's monthly allowance;

If we assume that the allowance was x dollars He therefore, went with half of his allowance for shopping, which is, x/2

Then;

Deducting $35.5, we get,

$(x/2 - 35.5)

Then, 3/5 of the remainder is on a book

Thus, 1 - 3/5 = 2/5 of the remainder (represents the amount that remained after buying a book and a shirt.

Therefore;

2/5 (x/2 - 35.5) = 28.5

We get;

x/2 - 35.5 = 28.5 (5/2)

x/2 - 35.5 = 71.25

 x/2 = 71.25 + 35.5

  x/2  = $ 106.75

    x = $ 106.75 × 2

       = $ 213.50

Therefore, Albert's monthly allowance is $ 213.50

The endpoints of a diameter of a circle are (3, -2) and (-5, 8). What is the equation of the circle in standard form?

Answers

Answer:

(x + 1)² + (y − 3)² = 41

Step-by-step explanation:

The center of the circle is the midpoint of the diameter.

(h, k) = ((x₂ + x₁)/2, (y₂ + y₁)/2)

(h, k) = ((3 + -5)/2, (-2 + 8)/2)

(h, k) = (-1, 3)

The radius is half the length of the diameter.

r = ½ √((x₂ − x₁)² + (y₂ − y₁)²)

r = ½ √((3 − -5)² + (-2 − 8)²)

r = ½ √(8² + 10²)

r = √41

Therefore, the equation of the circle is:

(x − h)² + (y − k)² = r²

(x + 1)² + (y − 3)² = 41

The standard form of equation of the circle is (x + 1) + (y - 3) = (6.40)².

What is distance between two points?

The length of the line segment bridging two points on a plane is known as the distance between the points.

The formula to find the distance between the two points is usually given by d=√{(x₂-x₁)² + (y₂-y₁)²}

Given is that the endpoints of a diameter of a circle are (3, -2) and (-5, 8).

The center: (3-5/2, -2+8/2) = (-1, 3)

The diameter d = √{(x₂-x₁)² + (y₂-y₁)²}

d = √{(-5-3)² + (8 + 2)²}

d = √{64 + 100}

d = √164

d = 12.81

The radius r = 6.40

The standard form of equation of the circle is,

(x + 1) + (y - 3) = (6.40)²

Deep Blue, a deep sea fishing company, bought a boat for $250,000. After 9 years, Deep Blue plans to sell it for a scrap value of $95,000. Assume linear depreciation.

Answers

Answer:

Therefore, we use the  linear depreciation and we get is 17222.22 .

Step-by-step explanation:

From Exercise we have that  is boat  $250,000.

The straight line depreciation for a boat  would be calculated as follows:

Cost  boat is $250,000.  

For  $95,000 Deep Blue plans to sell it after 9 years.

We use the formula and we calculate :

(250000-95000)/9=155000/9=17222.22

Therefore, we use the  linear depreciation and we get is 17222.22 .

To calculate the annual depreciation expense for Deep Blue's boat using the straight-line method, subtract the salvage value from the purchase price and divide by the number of years of useful life, resulting in an annual depreciation expense of $17,222.22.

To determine the annual depreciation, subtract the salvage value from the purchase price and divide by the useful life of the asset in years:

Subtract the salvage value from the purchase price: $250,000 - $95,000 = $155,000.

Divide the result by the number of years of useful life: $155,000 / 9 years = $17,222.22.

Therefore, Deep Blue would record an annual depreciation expense of $17,222.22.

The French club sold rose bouquets and chocolate hearts for Valentine's Day. The roses sold for $5 and the hearts sold for $3. The number of bouquets sold was 15 more than the number of hearts sold. If the club collected a total of $339, how many of each gift was sold?

Answers

Answer:

33 hearts sold, 48 roses sold

Step-by-step explanation:

x- number of roses sold

y- number of hearts sold

x=15+y <- " The number of bouquets sold was 15 more than the number of hearts sold"

5x+3y=339

5(15+y)+3y=339

75+5y+3y=339

8y=339-75

8y=264

y=33

x=15+33=48

Final answer:

The number of chocolate hearts sold was 33, and the number of bouquets sold was 48 for a total revenue of $339.

Explanation:

Let's assume the number of chocolate hearts sold was 'x'. Since the number of bouquets sold was 15 more than the number of hearts sold, the number of bouquets sold would be 'x + 15'.

The price of each rose bouquet is $5, so the total revenue from selling bouquets would be '5(x + 15)'.

Similarly, the price of each chocolate heart is $3, so the total revenue from selling hearts would be '3x'.

Since the total revenue collected was $339, we can set up an equation: '5(x + 15) + 3x = 339'.

Simplifying the equation, we get '8x + 75 = 339'.

Subtracting 75 from both sides of the equation, we get '8x = 264'.

Dividing both sides of the equation by 8, we get 'x = 33'.

Therefore, 33 chocolate hearts were sold, and the number of bouquets sold would be '33 + 15 = 48'.

Answers

Answer:

See the image.

Step-by-step explanation:

The function is given by [tex]g(x) = 3x^{2} - 12x - 3[/tex].

Differentiating the function, we get [tex]\frac{d g(x)}{dx} = 6x - 12[/tex].

Now, at x = 2, 6x - 12 will be 0.

Hence, at x = 2, either the function will have maximum or minimum value.

g(1) = 3 -12 -3 = -12.

g(0) = -3.

Hence, the given function passes through (2, -15), (1, -12) and (0, -3).

Find the height of a right square pyramid that has a rectangular base area of 70 square units and a volume of 140 cubic units. A. 2 units B. 6 units C. 1 units D. 18 units

Answers

Answer:

B) 6 units

Step-by-step explanation:

The formula of the volume of the Pyramid is 1/3×area of the base×height

1/3×70×height=140

Dividing both sides by 70

1/3×height=2

Multiplying both sides by 3

Height = 6

Final answer:

The height of a right square pyramid with a rectangular base area of 70 square units and a volume of 140 cubic units is 6 units, by using the volume formula of the pyramid.

Explanation:

The question asks us to find the height of a right square pyramid with a given base area and volume. To find the height, we need to use the formula for the volume of a pyramid, which is given by the formula: Volume = (Base Area * Height) / 3. We are given the base area as 70 square units and the volume as 140 cubic units.

Using the formula to solve for the height we get:
Height = (Volume * 3) / Base Area = (140 * 3) / 70 = 6 units. Therefore, the height of the pyramid is 6 units.

Pam is taking a train from the town of Rome to the town of Florence. Rome is located 40 miles due west of the town of Paris. Florence is 35 miles east, and 55 miles north of Rome. On her trip, how close does Pam get to Paris?

Answers

Answer:

Pan is closest to Paris when she gets to Florence when she is 35 miles away

Step-by-step explanation:

With Paris at (0,0), Rome is 40miles west which is on the negative x axis.

Florence is 35 miles closer (east to Paris) so we have -45 + 35 = -10

and 55 mikes north of Rome which is on the positive y-axis. So Florence is at point (-10,55)

The distance between the two points Florence and Paris is √(x2 - x1)^2 + (y2 - y1)^2

x1 = 0, y1 = 0

x2 = -10, y2 = 55

So we have

√(-10-0)^2 + (55-0)^2

= √(-10)^2 + (55)^2

= √ 100 + 3025

= √3125

= 55.9 mikes from Paris

Pam is closest to Paris when she gets to Florence when she is 35 miles away

Final answer:

Pam gets closest to Paris when she is 5 miles away, which occurs when she travels directly east from Rome before heading north to Florence.

Explanation:

Pam is taking a train from Rome to Florence, and we need to find out how close she gets to Paris along the way. Rome is 40 miles due west of Paris, and Florence is 35 miles east and 55 miles north of Rome. While traveling from Rome to Florence, Pam would initially get closer to Paris as she travels east, but as she moves north, the closest point to Paris would be directly east from Rome before moving north.

Step-by-Step Explanation

Determine the initial distance of Rome to Paris, which is 40 miles to the east.Since Florence is 35 miles east of Rome, Pam would at least come within 5 miles of Paris (40 miles - 35 miles).However, when traveling north to reach Florence, Pam's distance to Paris increases. Thus, the closest Pam gets to Paris on her trip is 5 miles, when she is directly east of Rome, before heading north.

  KEi = (1/2)(810 kg)(23.6 m/s)^2 ≈ 2.256×10^5 J . . . . . m is meters

At its final speed, the kinetic energy of the car is ...

  KEf = (1/2)(810 kg)(47.2 m/s)^2 ≈ 9.023×10^5 J

The ratio of final to initial kinetic energy is ...

  (9.023×10^5)/(2.256×10^5) = 4

4 times as much work must be done to stop the car.

_____

You know this without computing the kinetic energy. KE is proportional to the square of speed, so when the speed doubles, the KE is multiplied by 2^2 = 4.

Sean reads on Monday Tuesday and Wednesday. He reads 3 times as many minutes on Tuesday as he does on Monday. He reads 4 times as many minutes on Wednesday as he does on Monday. Sean reads 45 minutes on Tuesday. How many minutes does Sean read on Wednesday?

Answers

Sean reads 60 minutes on wednesday

Solution:

Given that,

Let "x" be the number of minutes read on monday

Let "y" be the number of minutes read on tuesday

Let "z" be the number of minutes read on wednesday

He reads 3 times as many minutes on Tuesday as he does on Monday

Number of minutes read on tuesday = 3 times the number of minutes read on monday

y = 3x --------- eqn 1

He reads 4 times as many minutes on Wednesday as he does on Monday

Number of minutes read on wednesday = 4 times the number of minutes read on monday

z = 4x ------- eqn 2

Sean reads 45 minutes on Tuesday

y = 45

Substitute y = 45 in eqn 1

45 = 3x

x = 15

Substitute x = 15 in eqn 2

z = 4(15)

z = 60

Thus he reads 60 minutes on wednesday

Final answer:

Sean reads for 60 minutes on Wednesday, calculated by knowing he reads four times as many minutes on Wednesday as on Monday, and he reads 45 minutes on Tuesday which is three times his Monday reading time.

Explanation:

Since Sean reads 3 times as many minutes on Tuesday as he does on Monday, and he reads 45 minutes on Tuesday, we can determine that he reads 45 minutes ÷ 3 = 15 minutes on Monday. Sean then reads 4 times as many minutes on Wednesday as he does on Monday. So, he must read 15 minutes × 4 = 60 minutes on Wednesday.

⇒How many solutions does the equation 10-3x +10x-7=5x-5+2x+8 have? a. One solution b. Two solutions c. No solutions d. Infinitely many solutions

Answers

Answer: d. Infinitely many solutions

Step-by-step explanation:

The given equation is expressed as

10-3x +10x-7 = 5x-5+2x+8

The first step is to make all the terms containing the variable to be on the left hand side of the equation and the constants to be on the right hand side of the equation.

10-3x +10x-7=5x-5+2x+8

10 - 7 + 10x - 3x = 5x + 2x - 5 + 8

7x + 3 = 7x + 3

Subtracting 7x and 3 from the left hand side and the right hand side of the equation, it becomes.

7x - 7x + 3 - 3 = 7x - 7x + 3 - 3

0 = 0

It has infinitely many solutions because as any value of x would satisfy both sides of the equation.

The formula for the surface area of a sphere is A=4pi r*2, where r is the length of the radius. Find the surface area of the sphere with a radius of 14. Use 22/7 as pi

Answers

Answer:

Step-by-step explanation:

area=4×22/7×14²=4×22×28=2464 units²

The surface area of a sphere with a radius of 14 is 2464 square units. When considering significant figures, this is rounded to 2500 square units to match the two significant digits of the given radius.

To find the surface area of a sphere with a radius of 14, using the given value of 22/7 for , the formula A = 4*pi*r2 is used. Plugging in the numbers:

A = 4 * (22/7) * (14)²

A = 4 * (22/7) * 196

A = 4 * 22 * 28

A = 88 * 28

A = 2464

Thus, the surface area of the sphere is 2464 square units.

A certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player (so the event B is contained in A). Suppose that P(A) = .625 and P(B) = .05. What is P(B/A)?

Answers

Answer:P(A/B)=0.08

Step-by-step explanation:

The probability formula to find p(A/B) is :

P(A/B) = p(A n B) / p(A)

Which means that B is contain in A and p(A n B) is p(B)

p(A n B)=p(B)=0.05

p(A)=0.625

Therefore

P(A/B) = p(A n B) / p(A)=p(B) / p(A)

P(A/B)=0.05 / 0.625

P(A/B)=0.08

What is a good science fair projects for 5th graders

Answers

I'm not sure of whether or not you're aware of this, but you asked this question in the math section. Nevertheless, I remember in 5th grade I did a project on whether or not it is possible to use solar energy to heat up different colored bags filled with water, and to determine which one would heat up the quickest. If that one doesn't pique your interest, you can go to sciencebuddies.com and search through a variety of project ideas if you'd like. That's where I found mine.

Final answer:

A good science fair project for 5th graders could be the 'Race of the Cans' experiment. Students can collect cans with different types of food and predict which can will win a race down an inclined plane.

Explanation:

A good science fair project for 5th graders could be the 'Race of the Cans' experiment. In this experiment, students can collect several cans containing different types of food and predict which can will win the race down an inclined plane. They can then explain their prediction and see if it is correct. Another option is to collect empty cylindrical containers of the same size and fill them with different materials like wet or dry sand to see how it affects the race.

[tex]\frac{w^{10}}{3y^{4}}[/tex]

Step-by-step explanation:

Given:

The given ration expressions are.

1. [tex]\frac{-2a^{2}b^{4}}{4ab^{-8}}[/tex]

2. [tex]\frac{-5w^{4}y^{-2}}{-15w^{-6}y^{2}}[/tex]

We need to simplify the given expressions.

Solution:

Part 1:-

Given expression is

[tex]=\frac{-2a^{2}b^{4}}{4ab^{-8}}[/tex]

Using law of exponents [tex]\frac{x^{m} }{x^{n} } = x^{(m-n)}[/tex]

[tex]=-\frac{a^{2-1}b^{4-(-8)}}{2}[/tex]

[tex]=-\frac{a^{1}b^{4+8}}{2}[/tex]

[tex]=-\frac{ab^{12}}{2}[/tex]

[tex]=-\frac{1}{2}ab^{12}[/tex]

Therefore, option first [tex]-\frac{1}{2}ab^{12}[/tex] is correct.

Part 2:-

Given expression is.

[tex]=\frac{-5w^{4}y^{-2}}{-15w^{-6}y^{2}}[/tex]

Using law of exponents [tex]\frac{x^{m} }{x^{n} } = x^{(m-n)}[/tex]

[tex]=\frac{w^{4-(-6)}y^{-2-2}}{3}[/tex]

[tex]=\frac{w^{4+6}y^{-4}}{3}[/tex]

[tex]=\frac{w^{10}y^{-4}}{3}[/tex]

[tex]=\frac{w^{10}}{3y^{4}}[/tex]

Therefore, third option [tex]\frac{w^{10}}{3y^{4}}[/tex] is correct.
