Answer:

1. $60

2. $240

Step-by-step explanation:

Use the formula for simple interest. Put your numbers in the formula and do the arithmetic.

i = Prt . . . . where i is the interest amount, P is the principal, r is the rate, t is the time period

1. P = $600, r = 0.05, t = 2, so you have ...

i = $600·0.05·2 = $60

i = $1500·0.04·4 = $240

Answer:

8 bags

Step-by-step explanation:

The area of the path is equal to the area of the overall square minus the area of the garden.

Area of a square is the side length squared:

A = s²

The overall square has a side length of 11 feet.  The side length of the garden is 11 - 2 - 2 = 7 feet.  So the area of the path is:

A = 11² - 7²

A = 121 - 49

A = 72

The area of the path is 72 ft².  If one bag of gravel covers 9 ft², then the number of bags needed is:

72 ft² × (1 bag / 9 ft²) = 8 bags

Answer:

$348.29

Step-by-step explanation:

The payment is calculated by multiplying the rate per hundred times the number of hundreds. The latter is found by dividing the loan amount by $100.

$2.41 × $14,452/$100 ≈ $348.29

Answer:$299.16

Step-by-step explanation:

Financed amount = $14452

APR  = 8.9%

Period / time = 5 years

monthly payment = $100 for every $2.07

To calculate the monthly payment of a financed amount we multiply the financed amount by the ratio of the given amount paid per $100

The monthly payment would be =  14452 * 2.07/100 = 14452 * 0.0207

= $299.16 approximately

therefore the monthly payment of a financed amount of $14452 is equal to $299.16

Answer:

  6w³ cubic units

Step-by-step explanation:

The volume of a right rectangular prism is the product of its dimensions:

  V = LWH

  = (2w)(w)(3w) = 6w³ . . . . cubic units

Answer:

6*W^3 cubic units

Step-by-step explanation:

Right rectangular prism volume (V) is calculated as

V = L*W*H

where L is length, W is width and H is height

The height is three times the width of the base means

H = 3*W

The length of the base is twice the width means

L = 2*W

Replacing in volume formula

V = 2*W*W*3W

V = 6*W^3

Julius bought a total of 2 gallons of beverages, including 2 quarts of orange juice and 16 cups of chocolate milk.

To find out how many gallons of beverages Julius bought, we need to convert each quantity to gallons and then sum them up:

1. **2 pints of milk**:

  - 1 pint = 0.125 gallons

  - 2 pints = [tex]\(2 \times 0.125 = 0.25\)[/tex] gallons

2. **2 quarts of orange juice**:

  - 1 quart = 0.25 gallons

  - 2 quarts = [tex]\(2 \times 0.25 = 0.5\)[/tex] gallons

3. **16 cups of chocolate milk**:

  - 1 cup = 0.0625 gallons

  - 16 cups =[tex]\(16 \times 0.0625 = 1\)[/tex] gallon

4. **32 ounces of lemonade**:

  - 1 ounce = 0.0078125 gallons

  - 32 ounces = [tex]\(32 \times 0.0078125 = 0.25\)[/tex] gallons

Now, let's sum up the quantities:

[tex]\[ 0.25 + 0.5 + 1 + 0.25 = 2 \][/tex]

So, Julius bought a total of 2 gallons of beverages.

Answer:

B. -14

Step-by-step explanation:

If you solve the system using the method of elimination, the y terms will automatically cancel each other out without any manipulation at all.  So go with it and solve for x first.  If the y terms cancel out, you're left with x = -3.

If x = -3, sub that value in for x in eitheer one of the original equations and solve for y:

[tex]3x-y=5[/tex] becomes

[tex]3(-3)-y=5[/tex] and

[tex]-9-y=5[/tex] so

Answer:

The answer is 12. There are 12 pens in each pack.

Step-by-step explanation:

The constant of proportionality between the number of packs and the number of pens that Frank buys is 12 pens per pack, calculated by dividing the total pens by the number of packs in both given scenarios.

The student asks about the constant of proportionality between the number of packs of pens and the number of pens. To find this, we divide the number of pens by the number of packs for each given scenario to ensure the ratio is consistent.

Given Frank buys three packs and ends up with 36 pens, we divide 36 pens by 3 packs to get 12 pens per pack.

When he buys five packs and has 60 pens, we again divide 60 pens by 5 packs and get the same result, 12 pens per pack. Therefore, the constant of proportionality is 12 pens per pack.

Step-by-step explanation:

Given

f(x) = - (x - 3)(x + 11)

Find the zeros by setting f(x) = 0, that is

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 11 = 0 ⇒ x = - 11

The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros

[tex]x_{vertex}[/tex] = [tex]\frac{3-11}{2}[/tex] = [tex]\frac{-8}{2}[/tex] = - 4

Answer:

Step-by-step explanation:

The sum of those numbers is 14.  Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000.  So if a person invests 2 parts, he invests 2(10,000).  A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000).  That gives us 20,000 + 50,000 + 70,000 = ?  

(140,000)

The difference in investment between the largest and the smallest is 50,000

Final answer:

To find out the investments of three friends in a ratio of 2:5:7, one part is calculated as $10,000. The smallest investor contributes $20,000 and the largest investor contributes $70,000. Hence, the difference in their investments is $50,000.

Explanation:

The question is asking to determine the individual investments of three friends in a food truck business based on their total contributions amounting to $140,000 and the ratio of their investments being 2:5:7. First, we find the total number of parts in the ratio (2+5+7=14 parts). To find the value of one part, we divide the total investment by the number of parts ($140,000 \/ 14 = $10,000 per part).

Now, we can calculate each friend's investment:

The difference in investment between the smallest and the largest investor is $70,000 - $20,000 = $50,000.

First, you have to find the 52% of the 30%(chance that he gets a dividend) .Then you simply have to subtract the result (15.6%) from the 30%. Your result is 14.4% chance that he wont get a divident.

Answer:

14.4%

Step-by-step explanation:

An investment advisor believes that there is a 30% chance of making money by investing in a specific stock. If the stock makes money, then there is a 52% chance that among those making money, they would also get a dividend. Find the probability that the investor makes money but does not receive a dividend.

Probability is the chance/likelihood that an event will occur or not

The chances that one makes money from a stock is 30%

Chances that one will not=70%

Chances that there will dividend among those who made money is =52%

chances that there wont be dividend is =100%-52%=48%

the probability that One will make money and not receive a dividend

is 30%*(100%-52%)

14.4%

Answer:

255

Step-by-step explanation:

1. 75% is actually 0.75, and you want to find 75% of 340.

2. Multiply 0.75 and 340. 0.75 x 340 = 255

Answer:

Option B is correct.

Step-by-step explanation:

Given:

A Solid Figure made up pf cuboid and a triangular based prism.

To find: Total Surface area of the figure.

Total Surface Area = Area of front + Area of top + Area of Back + 2 × Area of side + Area of bottom

Area of Front = Area of Square + Area of rectangle

                      = 10 × 10

                      = 100 in.²

Area of top = Area of Rectangle

                   = 13 × 10

                   = 130 in.²

Area of back =  Area of square in down + Area of rectangle in up

                      = 10 × 10 + 5 × 10

                      = 100 + 50

                      = 150 in.²

Area of the bottom = Area of the rectangle

                                = 12 × 10

                                = 120 in.²

Area of the side = Area of rectangle + Area of the triangle

                           = 12 × 10 + 1/2 × 5 × 12

                           = 120 + 5 × 6

                           = 120 + 30

                           = 150 in.²

Total Surface Area = 100 + 130 +150 + 120 + 2 × 150

                               = 500 + 300

                               = 800 in.²

Therefore, Option B is correct.

Answer:

7/15

Step-by-step explanation:

odd numbers are those that do not have divides ie1,2,3,5,7,11,13

The probability of randomly selecting an odd number from the numbers 1-15 is 8/15.

Probability is used to know the odds that an event would happen.  The probability the event occurs is 1 and the probability that the event does not occur is 0.

Probability that a randomly selected number would be odd = number of odd numbers / total numbers

Odd numbers between 1 and 15 = 1 , 3, 5, 7, 9, 11, 13, 15

Probability that a randomly selected number would be odd = 8/15
