Answer:
3 1/2 hours.
Step-by-step explanation:
If the Half Time show is one-seventh of the show and lasts for 30 minutes, we can multiply that by 7 to get the total amount of minutes.
30 x 7 = 210
To convert the number of minutes to hours, 210 can be divided by 60 to result in a total of 3.5, therefore, the Super Bowl lasts for 3 1/2 hours.
V = L * W * H
V = 4 * 4 * 8
V = 16 * 8
V = 128 cubic ft
Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:
![49x^2-9=(7x)^2-3^2=(7x+3)(7x-3)](https://tex.z-dn.net/?f=49x%5E2-9%3D%287x%29%5E2-3%5E2%3D%287x%2B3%29%287x-3%29)
Thus, the answer is A.
Hope this helps!
C is the answer to that question i think
