Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so
- The length of the fencing is 80 meters, so
Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:
Then substitute for y in the first:
b) To maximize A, find the zero of the first derivative:
So y = (80-40)/2 = 20 meters.

To sum up, <em>corresponding parts of congruent triangles are always congruent</em> [<em>CPCTC</em>].
1. The edge and angle markings of both triangles represent all corresponding parts. Each angle and edge corresponds with another angle and edge.

Answer:
H₁ = The local pizza takes less time than the chain.
H₀= The local pizza takes more time than the chain.
Step-by-step explanation:
Since you want to know if the advertisement by the local pizza restaurant ("It delivers to the dormitories faster than a local branch of a national chain") is true, the hypothesis to be performed is
H₁ = The local pizza takes less time than the chain.
H₀= The local pizza takes more time than the chain.
So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3
