Check the picture below.
it hits it twice, once at the beginning, 0 seconds, and when it hits the ground at the end.

Answer: A, B, D are irrational</h3>
Basically everything but choice C
==========================================
Explanation:
sqrt is shorthand for square root
sqrt(4) = 2 = 2/1 showing that sqrt(4) is rational. We can write it as a fraction of two whole numbers, where 0 is not in the denominator.
-------
In contrast, we cannot write sqrt(2), sqrt(3), or sqrt(5) as a fraction of two whole numbers. Using your calculator, note how
sqrt(2) = 1.4142135623731
sqrt(3) = 1.73205080756888
sqrt(5) = 2.23606797749979
all of those decimal expansions go on forever without any pattern, which is a sign that those numbers are irrational. If they were rational, then a pattern would repeat at some point or the decimals would terminate at some point.
Answer:

Step-by-step explanation:
8 times 7 times 25 = the volume
=1400
Answer:
Both people did the same type of general question, but Jenna's method uses the distributive property to do it mentally.
Step-by-step explanation:
Jenna's Method: Uses distributive property to break it all down and do it mentally.
Mia's Method: She broke the equation down so much that the answer will be more complex to find.
Assuming he spends all the $24 on renting DVD's we can simply divide the money he has available with the price of each DVD in order to know how many he can buy.
$24/$4 = 6
Jack can rent a maximum of 6 DVD's
