Answer - 3

B = 36/ (12-9*5)
B = 36/ (12- 45)
B = 36/ (-33)
E = N/A
D = 3
M = N/A
A = N/A
S = N/A

Answer:

12/11

Step-by-step explanation:

Any work inside parentheses must be done first.

Thus, start with (3 + 6); this equals 9. Then the original expression becomes

36÷{12-(9)*5}

Multiplication and division are done before addition and subtraction. Thus, the next stp is to multiply 9 and 5, obtaining 45, inside the parentheses. This results in

36÷{12-45}, or 36÷{33}, which leads to the answer 36/33, or 12/11.

3. Bob the Builder wants to earn an annual rate of 10% on his investments,

mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

$T = E + P$

In this question:

Rate of 10%, so I = 0.1.

9 months, so $t = \frac{9}{12} = 0.75$

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

$T = E + P$

$3000 = E + P$

$E = 3000 - P$

Then

$E = P*I*t$

$3000 - P = P*0.1*0.75$

$1.075P = 3000$

$P = \frac{3000}{1.075}$

$P = 2790.7$

He should pay $2,790.7.

You are applying fertilizer to a football field. The field is 360 feet long and 160 feet wide. You use 8 pounds of fertilizer pe

Assoli18 [71]

Answer: 10 bags

Step-by-step explanation:

First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

$A =360*160\\\\A = 57600 ft^2$

You use 8 pounds of fertilizer per 1,000 square feet

So the amount of fertilizer you should use is:

$57,600 ft^2 * \frac{8\ pounds}{1,000\ ft^2} = 460.8\ pounds$

As the fertilizer comes in bags of 50 pound then you need

$460.8\ pounds * \frac{1\ bag}{50\ pounds} = 9.2\ bags$

Since you can not buy 9.2 bags then we round up to the next whole number.

Finally you need 10 bags of fertilizer
