Answer:
17 %
Step-by-step explanation:
12 of 72 cars needed mufflers
% = cars needing mufflers/total cars × 100 %
= 12/72 × 100 %
= 17 %
17 % of the cars serviced needed muflers.
Let's look at the picture, let's imagine that the gray line is the perimeter fence and that the red OR the blue is the one dividing it. We can see that the blue line is longer than the red one, so it will be advantageous, to have a bigger area, to have the dividing fence the smallest possible.
Let's say then that the width (W) is bigger (or equal) to the length (L), so we have:

The area is W*L, so we have

this function is a parabola facing down, its zeros are 0 and 80, therefore its maximum is when L=40
hence, L=40 and W=(240-120)/2=60
It will be a rectangle, measuring 60x40 and the divinding fence will be 40
Answer:
A
Step-by-step explanation:
√(x^5) = x^(5/2) = (x^2)√x
√9x = (√9)(√x) = (3)√x
which means: ((x^2)√x) + ((3)√x)
since both have a √x, you can factor it out. for example...if you look at A, if you apply the distributive property you can see it expands back out. hmu if you need a different. explanation
Answer:
B. 
Step-by-step explanation:
Total paper in the hat:
2 blue + 6 red + 10 yellow + 7 purple = 25 total pieces of paper
P(AB) = 7 / 25 x 2 / 25
A is the probability of pulling a purple paper
B is the probability of pulling a blue paper
