Answer:
Step-by-step explanation:
labor cost = 20 * h = 20h
Total cost = 100 + 20h
The total 'parts' of the ratio is 10 (3+7).
Complementary angles add to 90 degrees.

Each 'part' is 9.
3:7 * 9 = 27:63
One angle is 27 degrees and the other is 63 degrees.
Answer:
Pie chart
Step-by-step explanation:
Given that a professor has kept records on grades that students have earned in his class
He wants to examine the percentage of students earning the grades A, B, C, D, and F during the most recent term,
We have to find which kind of plot could he make
Box plot gives comparison for interval of scores this is to some extent helpful to find out the percentage of students getting a range of scores
Timeplot is irrelevant here. Dot plot will not be of much use.
Histogram is to some extent useful as box plot
But the best one is pie chart giving easy visual comparison for various grades A, B,C,D,E and F
