2. Lena can finish 2 math homework problems in 15 minutes. At this rate, how many problems can she finish in 75 minutes? Use the rate table below to find the answer.

10.

Because the ratio is how many problems:How much time so it is 2:15

Multiply each side by 5 10:75

So that means 10 problems in 75 minuets.

HOPE THIS HELPED!!!

10

Step-by-step explanation:

Set up the following proportion.

2 questions /15 minutes = x questions / 75 minutes.

Notice that both ratios are set up the same way -- questions / time. All proportions are set up the same way.

Mulltiply both sides by 75

2 * 75 / 15 = x

2 * 5 = x

x = 10

She would be able to solve 10 problems in 75 minutes.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
