Let d(t) be the total number of miles Joanna has cycled, and let t represent the number of hours after stopping for a break duri

katrin [286]

For this case we have the following equation:
$d (t) = 12t + 20
$
The variables are:
t: time in hours
d (t): distance traveled in miles.
We evaluate the distance traveled after 4 hours.
So we have that for t = 4:
$d (4) = 12 (4) +20

d (4) = 48 + 20

d (4) = 68$
Answer:
d (4) = 68
This means that after 4 hours Joanna cycled for 68 miles total

A swimming pool has has to be drained for maintenance the pool shaped like a cylinder with a diameter of 8 meters and a depth of

Alexandra [31]

<span>Step 1: find the radius
The radius is half of the diameter. So the radius is 8 because the diameter is 16.

Step 2: square the radius.
8^2 = 64

Step 3: plug into formula
pi * radius squared * height
3.14 * (64) * (1.8) = 361.728 m^3
The volume of the pool is 361. 728 meters cubed.

Step 4: Divide volume by the amount pumped out per hour
volume / amount pumped out = amount of hours
361.728/16 = 22.608 hours.

So your answer is approximately 23 hours.</span><span> </span>
