Yes, it is directly proportional.
Step-by-step explanation:
Since Anna does a sit-up at a certain amount of time, then we have two quantities we are comparing: a sit up and the amount of time it takes.
It is said that the tired she gets, the more time she uses. Therefore, as her tiredness increases, the amount of time also increases. This implies that the quantities are proportional, directly proportional.

Step-by-step explanation:
Use to formula...
21!/((21-3)!(3!) = 1330
Answer:
19
Step-by-step explanation:
use the formula v = πR^2H. This is to find the volume of the cylinder.
Radius is half the diameter and you know that the diameter is 2. So half of 2 is 1.
And the height of the cylinder is already given, 6.
enter into a calculator π(1)^2(6) and you get 18.85.
If you round to the nearest cubic foot, 18.85 would then round up to about 19
