Pat has been assigned the job of picking apples from the family orchard. He could do the job alone in 8 hours. He knows that his
schepotkina [342]

Answer:

3.7 hours

Step-by-step explanation:

Pat could do the job alone in 8 hours.

Patti could do the job alone in 7 hours

Output = Rate * time

Let the rate at which pat does the work = Rp

Let the rate at which Patti does the work = Rt

Let X be the total output

Rp * 8 = X

Rp = X/8

Rt * 7 = X

Rt = X/7

If both pat and Patti pick apples, we have

(Rp+Rt)T = X

(X/8 + X/7)T = X

[(7X + 8X)/56]T = X

[X(7+8)/56]T = X

Divide both sides by X

[(7+8)/56]T = 1

(15/56)T = 1

T = 56/15

T = 3.7 hours

The area of a quarter circle is 38.465 square<br> inches. What is the quarter circle's radius?
LuckyWell [14K]

The formula for a circle's area is A=\pi r^2. We are given an area of 38.465 square inches for a quarter of it.

Multiply this value by 4 to compensate for the quarter circle.

4 \times 38.465=\pi r^2

153.86=\pi r^2

Divide both sides by pi (Note: I'm using the conventional value of 3.14)

49=r^2

Take the positive square root of both sides

7=r

The radius is 7 inches. Let me know if you have any questions, thanks!
