Answer:
She spends 2 hours driving.
Step-by-step explanation:
The formula given is:

In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.
Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.
This means that 
To the nearest hour, how many hours does she spend driving?
We have to find t. So




Rounding to the nearest hour
She spends 2 hours driving.
Answer:
r·sin Ф = 5(r·cos Ф) - 2
Step-by-step explanation:
y = r·sin Ф and x = r·cos Ф, and so
y = 5x - 2 becomes
r·sin Ф = 5(r·cos Ф) - 2
Answer:
15
Step-by-step explanation:
x + 3 = 2(x - 6)
x + 3 = 2x - 12
-1x = -15
=15
A = bh
A = 5.4 x 3.8 = 20.52
20.52 x 4 = 82.08
So, the answer is 82.08 m^2
