Answer 2

Answer:

D. Subtract the sum of the three test scores from the product of 75 and 5, and divide the result by 2

Step-by-step explanation:

Alright imma try and make this as simple as possible.

My steps:

1) follow the answers steps:

(100 + 85 + 70) - (75 • 5) = -120

-120 divided by 2 = -60

Now, yes the answer is negative but check this out!

3) add 60 twice to 100, 85, and 70: ( 100 + 85 + 70 + 60 + 60) = 375

4) then divide 375 by 5: 375 divided by 5 = 75

Which is our mean! And there you have it! I really hoped this helped and your not confused. Good luck! :)

Answer:

i believe it is 231 yd squared

Step-by-step explanation:

Answer:

1. 231 yd²

2. 78 ft²

3. 28 inches

4. 57.5 centimeters

5. 258 cm²

Step-by-step explanation:

That is not geometry, but here are your answers.

A = bh

A = 13.2 × 17.5

A = 231 yd²

[tex]A=\frac{bh}{2}[/tex]

[tex]A=\frac{(13)(12)}{2}[/tex]

[tex]A=\frac{156}{2}[/tex]

A = 78

[tex]b=2\frac{A}{h}[/tex]

[tex]b=2\frac{364}{28}[/tex]

b = 28

[tex]h=2\frac{A}{a+b}[/tex]

[tex]h=2\frac{5405}{65+123}[/tex]

[tex]h=2\frac{5405}{188}[/tex]

[tex]h=2(28.75)[/tex]

h = 57.5

A = a²

A = 12²

A = 144 cm²

12 ÷ 2 = 6

[tex]A=\frac{(h)(b)}{2}[/tex]

[tex]A=\frac{114}{2}[/tex]

A = 57

57 cm² + 57 cm² = 114 cm²

114 cm² + 144 cm² = 258 cm²

A golf course has a circular island of grass with a diameter of 15 yards. The mowing company charges $6.50 per square yard. How much will the golf course have to pay to maintain the grass on the circular island?

Answers

Answer:

about $1148.06

Step-by-step explanation:

Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.

Area = radius * radius * pi

You are told that the diameter = 15 yards. We also know that the radius that we need is half of the diameter. Radius = 7.5 yards.

This means that the Area = 7.5 * 7.5 * 3.14 = 176.625 square yards

Then we multiply by the cost per square yard:

176.625 * 6.50 = 1148.06 is your answer

Answer:
Will cost about $1148.62

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?

With step by step explanation = Brainliest

Answers

Answer:

don't know

Step-by-step explanation:

ok please mark mr brainlist

Answer:

3%

Step-by-step explanation:

Interest rat is calculated by using the equation A = P(1 + r)^n

A is the amount after interest. Here, it is 1635.30

P is the principal, or base, amount. Here, it is 1422

r is the rate at which there is interest. It is what we need to find out.

n is the amount of years interest is calculated for. Here, it is 5

Now that we have everything, we calculate:

1635.30 = 1422(1 + r)^5

Now we have to get r on one side of the equation by itself:

Divide both sides by 1422:

1635.30/1422 = (1 + r)^5

5√(1655.30/1422) = 1 + r

5√(1.16406469) - 1 = r

Now r is on one side of the equation.

The 5th root of 1.16406469 is 1.03084987

1.03084987 - 1 = 0.0308, so it is 3%

The 5√ is the 5th root of the numbers

Or it's 2.835 percent I don't know
