If you would like to know how far did Mackenzie run in one hour, you can calculate this using the following steps:
26 1/5 = 131/5 miles ... 5 4/5 = 29/5 hours
x miles = ? ... 1 hour
131/5 * 1 = 29/5 * x
131/5 = 29/5 * x
x = 131/5 * 5/29
x = 131/29
x = 4 15/29 miles
The correct result would be <span>4 15/29 miles.</span>
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
If the x is also supposed to be included in the radical, then you should be
which simplifies to
or approximately 4.24
If the x is on the outside,
simplifies to
. Now do
in a calculator to get approximately - 1.10
