Joe does 140 push-ups and 150 sit-ups each day. How many push-ups and sit-ups will Joe do in 5 days?

Joe will do 700 push-ups , and 750 sit-ups in 5 days.

Step-by-step explanation:

700 push ups and 750 sit ups

Step-by-step explanation: if you do the multiplication or addition. Joe would be doing 140, then 280, 420, 560, then 700. When he does his lush ups, he would be doing 150, then 300, 450, 600, then 750. Tried my best to explain.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer is (-4,-4)

hope this ! : d
