The answer is B, which is 4q
Answer:
30
Step-by-step explanation:
40
x 0.75
-----------
= 30
We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.
distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A

There is no question 17.

15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.
The equation would be y=0.45x.
Let x be the number of cookies Matt made. Since Phil made 25% more, and 100%+25%=125%=125/100=1.25, the number of cookies Phil made can be represented by 1.25x.
Together the cookies they made are represented by x+1.25x=2.25x
Since there were 20% of the cookies remaining, this means they sold 100%-20%=80%=80/100=0.8 of the cookies:
0.8(2.25x) = 1.8x
Each cookie sold for 0.25, so we have
0.25(1.8x) = 0.45x
Letting y be the money they make, we have
0.45x=y
Answer: 
Step-by-step explanation:
Given
The slant height of the square pyramid is 
The length of the side of the base is 
for the square pyramid, height is given by
![\Rightarrow h=\sqrt{l^2-r^2}\quad \quad [\text{where r=}\frac{a}{2}]\\\Rightarrow h=\sqrt{25^2-7^2}\\\Rightarrow h=\sqrt{625-49}\\\Rightarrow h=\sqrt{576}\\\Rightarrow h=24\ ft](https://tex.z-dn.net/?f=%5CRightarrow%20h%3D%5Csqrt%7Bl%5E2-r%5E2%7D%5Cquad%20%5Cquad%20%5B%5Ctext%7Bwhere%20r%3D%7D%5Cfrac%7Ba%7D%7B2%7D%5D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B25%5E2-7%5E2%7D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B625-49%7D%5C%5C%5CRightarrow%20h%3D%5Csqrt%7B576%7D%5C%5C%5CRightarrow%20h%3D24%5C%20ft)
Thus, the height of the prism is
