a) Corresponding angles of similar figures are congruent, so 
b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is 
c) Since the scale factor is 5/2,
Minus 5 from both sides so we have 3a=-19 now divide both sides by 3 so we have a=-6 1/3
Answer:
They are equivalent because they equal the same, but the numbers are just flipped around. True
Step-by-step explanation:
The answer is the third option. add up all the test scores and divide them by the number of people whose scores you added
which would be three people
50 X (40 X$20) = 50 X $800 = $40,000
15 X (4 X (50% X $20+ $50)) = 15 X (4 X $60) = 15 X 240 = $3600
$40,000 + $3600 = $43,600 Total payroll
$3,600/$43,600 = .0825688073 as a percent rounded to the nearest tenth is 8.3%
