Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span>

--- (1)
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' =

--- (2)
As (1) = (2), hence the lines are parallel and their slope is

(Option A).
Answer: She had 27.2% correct.
Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

40% will be the part and 68% will be the whole.
<u><em>Step 1.</em></u>
Convert 40 into a decimal by dividing it by 100.
40 ÷ 100 = 0.4
<u><em>Step 2.</em></u>
Multiply 0.4 by 68.
0.4 × 68 = 27.2
Hence, she had 27.2% correct.
Answer:
13054.6
Step-by-step explanation:
multiply 812 by 2.30 then multiply 4310 by 2.70 then add both answers together.
Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108
