Answer:
![300\ people](https://tex.z-dn.net/?f=300%5C%20people)
Step-by-step explanation:
Let
x-----> the total number of people in a survey
we know that
![27\%=27/100=0.27](https://tex.z-dn.net/?f=27%5C%25%3D27%2F100%3D0.27)
so
![0.27x=81](https://tex.z-dn.net/?f=0.27x%3D81)
Solve for x
Divide by 0.27 both sides
![x=81/0.27](https://tex.z-dn.net/?f=x%3D81%2F0.27)
![x=300\ people](https://tex.z-dn.net/?f=x%3D300%5C%20people)
Answer:
2.98×10^-6 hrs
Step-by-step explanation:
Speed = Distance/Time
Time = Distance/speed
Given
Distance = 17in
Speed= 90mph
Convert inches to miles
1in = 1.578 × 10-5 mile
17in = 17(1.578 × 10-5) mile
17in = 26.826×10^-5miles
Get the time
Time =26.826×10^-5/90
Time = 0.298×10^-5
Time = 2.98×10^-6 hrs
