Answer:
B.) 166
Step-by-step explanation:
10 x 2 = 20
12 x 10 = 120
13 x 2 = 26
20 + 120 + 26 = 166
Square of five = 5^2 = 5 x 5 = 25
answer
c) 25
Answer:
a. 0.133 pushups/s b. 8 pushups/s c. 1200 pushups/s
Step-by-step explanation:
To write the rate in 3 different ways, we have to use seconds, minutes and hours respectively for the time.
So, a. Number of pushups per second
rate, R₁ = number of pushups per second
= number of pushups/ total time in seconds
= 40 pushups/(5 × 60) s
= 40 pushups/300 s
= 0.133 pushups/s
b. Number of pushups per minute
rate, R₂ = number of pushups per minute
= number of pushups/ total time in minutes
= 40 pushups/5 min
= 8 pushups/s
c. Number of pushups per hour
rate, R₃ = number of pushups per hour
= number of pushups/ total time in seconds
= 40 pushups/(5 ÷ 60) s
= 40 pushups/(1/30) h
= 40 × 30 pushups/s
= 1200 pushups/s
