Find the area and perimeter of the triangle below if a = 164 feet, b=221 feet, c=352 feet, and h=76 feet

Answers

Answer:

Perimeter=737 feets

Area=13542.6 ft²

Step-by-step explanation:

Well assuming that a,b,c are the three sides of the triangle and h is the height then;

Perimeter=distance around the figure

P=164+221+352= 737 feet

Area of a triangle given three sides is calculated using the formulae;

Area=√s (s-a) (s-b) (s-c) where  s=(a+b+c)/2

Finding s;

s=(164+221+352)/2 =368.5 feet

Finding the area

A= √ 368.5 (368.5-164) (368.5-221) (368.5-352)

A=√368.5 (204.5) (147.5) (16.5)

A= 13542.6 ft²

Printer B uses $15 in ink every hour. What is the ink cost for each card coming from printer B?

Answers

Answer:

$0.2456 / card in ink for printer B

Step-by-step explanation:

The formatting of the data tables isn't great in your question and it's hard to be sure of which numbers go where.

Since the question is about printer B, we'll assume the number of hours for printer B is 50 for week1, 50 for week2 and 3 for week3.

The numbers don't make much sense overall, but let's work with them.

We'll first calculate the ratio of hours worked by printer B with the overall hours all the printers worked, over the 3 weeks:

Printer A : 140 hours

Printer B : 130 hours

Printer C: 145 hours

Total 415 hours total, for the 3 printers.

Ratio of Printer B: 130 / 415 = 31.325%

Total of cards produced:

7,950 + 7,800 + 9,600 = 25,350 cards over 3 weeks.

We'll assume the productivity per hour is the same for all printers, since no indication otherwise.  So, the portion of those 25K cards of printer B should be the same as the ratio of the hours worked:

25,340 * 31.325% = 7941 cards (rounded to the nearest unit)

Since we know printer B ran for 130 hours, and it costs $15/hour in ink, we have:

130 hours * 15$/hour = $1,950 in ink.

Now, we divide by the number of cards:

$1,950 / 7941 cards = $0.2456 / card in ink for printer B

Answers

Answer:

25 in.

Step-by-step explanation:

Since we know geckos are 2/5 of an Iguana's length, we need to find the length of 1/5.

So if 10 in. is 2/5, 5 in, is 1/5.

Now, since the denominator is 5, we multiply 5 in. by 5.

5x5=25 in.

25 in. is the length of an average Iguana.

tx²+3x-7=0 has two real solution. what can be the deducted about the value of t?

Answers

Answer:

value of t is greater than equal to -9 / 28.

Step-by-step explanation:

Given Quadratic Polynomial :  tx² + 3x - 7 = 0

Also, It has real solutions.

Standard Quadratic equation, is ax² + bx + c = 0

here, Determinant, D = b² - 4ac

decides nature of the roots.

if D < 0 , roots / solutions are complex

if D = 0 , roots are real and equal.

if D > 0 , roots are real and different.

As given roots are real solutions.

Means Dis either equal to 0 or greater than 0

when D = 0

we have, 3² - 4 × t × (-7) = 0

               9 + 28t = 0

               t = -9 / 28

when D > 0

we have, 3² - 4 × t × (-7) > 0

               9 + 28t > 0

               t > -9 / 28

Therefore, value of t is greater than equal to -9 / 28.

What is angle E and what is the process finding it?

Answers

Answer: 39 degrees

Step-by-step explanation: The angle sum of a triangle is 180 degrees so we take 102 from 180.

180-102=78

Since the two angles are the same then we just divide 78 by 2

78/2=39

Answer:

∠E ≈ 37°

Step-by-step explanation:

Using the Sine Rule in ΔEFG, that is

[tex]\frac{26}{sinE}[/tex] = [tex]\frac{42}{sin102}[/tex] ( cross- multiply )

42 × sinE = 26 × sin102° ( divide both sides by 42 )

E = [tex]sin^{-1}[/tex] (0.6055 ) ≈ 37°

How to convert it?

Some quadratic equations are difficult to factor and are not presented in a way that enables us to apply the square root property right away. However, by "completing the square," we may transform the quadratic formula into a perfect square trinomial. The square root property is then used to factor the trinomial and answer the equation.

How to Complete the Square in Equations to Solve the Problem

1. Transform the original equation into x2 + bx = c.

2. Add the term required to complete the square to both sides.

3. Factor the trinomial with a perfect square.

4. Apply the square root property to the resulting equation

If x2 + bx is a binomial, then adding  will result in a perfect square trinomial.   is the square of half the coefficient of the linear x.  

A perfect square trinomial can be factored, so the equation can then be solved by taking the square root of both sides.

The number of DVDs in a random person’s home collection is counted for a sample population of 80 people. The mean of the sample is 52 movies; the entire population is known to have a standard deviation of 12 movies. Assuming a 99% confidence level, find the margin of error.

Answers

Answer:

[tex]E = 3.46\ movies[/tex]

Step-by-step explanation:

The formula to find the error is:

[tex]E = z_{\frac{\alpha}{2}}\frac{\sigma}{\sqrt{n}}[/tex]

Where:

[tex]\sigma[/tex] is the standard deviation

n is the sample size

So

n = 80 people

[tex]\sigma[/tex] = 12 movies

A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number?

Answers

Answer:

4153

Step-by-step explanation:

(x-3)/10 + 3000 = x-73

(x-3)/10 = x - 3738

x-3 = 10x - 37380

 x = 10x - 37377

-9x = -37377

 x = 4153

: P

Answer:

4153

Step-by-step explanation:

Let the original number be x

First, you subtract 3 from the original number. This removes 3 from the last digit, but leaves a zero there.

Now to remove the zero, you divide by 10.

Finally, to put the 3 at the first position, you add 3000.

Now Moving the last digit, 3, to the first position the number becomes :[tex]\frac{x-3}{10}+3000[/tex]

We are given that the number will decrease by 738.

A.T.Q

[tex]\frac{x-3}{10} + 3000 = x-738[/tex]

[tex]\frac{x-3}{10}= x - 3738[/tex]

[tex]x-3 = 10x - 37380[/tex]

[tex]x = 10x - 37377[/tex]

[tex]-9x = -37377[/tex]

[tex]x = 4153[/tex]

Hence the original 4-digit number is 4153.

Step-by-step explanation:

A parabola is symmetric about the vertex point. The x-coordinate of the vertex is 4.6.

So the parabola has 1 intersection point at x = 0 (origin as shown) and the line of symmetry is at x = 4.6. That is, from 0 to 4.6, it is 4.6 units. Hence, the other intersection point at the x-axis should be from 4.6 to 4.6 units to the right.

Hence, 4.6 + 4.6 = 9.2

The x-intercept would be (9.2, 0)

Using the identity cos x = sin(90 - x):

20 + x = 90 - x

2x = 70

x = 35 degrees (answer).

Answer:

Value of x is 35°.

 

Step-by-step explanation:

Given:

cos x = sin ( 20 + x )

To find: Value of the x.

We know that [tex]sin\,(90-\theta)=cos\,\theta[/tex]

Consider,

cos x = sin ( 20 + x )

sin ( 90 - x ) = sin ( 20 + x )

Comparing both sides,

90 - x = 20 + x

-x - x = 20 - 90

-2x = -70

x = 35°

Therefore, Value of x is 35°.

Kim is making a bouquet for her friend. She used x tulips and some daffodils in the bouquet. The number of daffodils is equal to the square root of the number of tulips. If the total number of flowers in the bouquet is 20, find the number of tulips.

5
16
20
4

Answers

Answer:

16

Step-by-step explanation:

So the number of tulips (t) plus the number of daffodils (d) should equal up to 20. So if we write that as an equation, it would t + d = 20. So now we have to find what two numbers could add up to 20, but let's not forget that the number of daffodils is equal to the square root of the number of tulips.

So now we have to find a number when added to its square root is 20. So going by process of elimination, you can eliminate 5 because the square root of that is a decimal and 5 plus a decimal isn't going to add up to 20. You know you can eliminate 20 because it already reaches the limit with the number of tulips, not allowing enough room for daffodils. You can eliminate 4 because the square root of that is 2, and 4 + 2 = 6, not 20.

So that leaves 16... The square root of 16 is 4, because 4 divided by itself twice equals 16. Now, let's add them and see if it equals 20. 16 tulips + 4 daffodils = 20. So 16 is your answer.

Sorry I am bad at explaining things, but I hope this helps anyway!

Answer:

Option B is the correct answer.

Step-by-step explanation:

She used x tulips and some daffodils in the bouquet.

The number of daffodils is equal to the square root of the number of tulips.

[tex]\texttt{Number of daffodils = }\sqrt{x}[/tex]

The total number of flowers in the bouquet is 20

That is

             [tex]x+\sqrt{x}=20[/tex]

Solving

         [tex]x+\sqrt{x}=20\\\\\sqrt{x}=20-x\\\\x=(20-x)^2\\\\x=400-40x+x^2\\\\x^2-41x+400=0\\\\(x-25)(x-16)=0\\\\\texttt{x=25 or x = 16}[/tex]

Total number is less than 20 so 25 is not possible

Number of tulips used = 16

Option B is the correct answer.

Mike can afford to buy 5 $20 games.

To determine how many $20 games Mike can afford to buy with $100, we divide the total amount of money he has by the cost of one game.

Total money Mike has = $100

Cost of one game = $20

Number of games Mike can afford = Total money / Cost of one game

Number of games Mike can afford = $100 / $20

Number of games Mike can afford = 5

Therefore, Mike can buy 5 games with $100.
