Problem 1, part (a)
<h3>Answer: False</h3>
For instance, 200 feet in real life can be reduced to scale down to say 2 inches on paper. So we have a reduction going on, and not an enlargement.
====================================================
Problem 1, part (b)
<h3>Answer: true</h3>
This is because a scale drawing involves similar polygons. This is true whenever any dilation is applied.
====================================================
Problem 2
I'm not sure how your teacher wanted you to answer this question. S/he didn't give you any numbers for the side lengths of the polygon. The angle measures are missing as well.
Answer:
180%
Step-by-step explanation:
It is 180% because one rectangle is fully shaded which means that is 100%. THe other one is 4/5 of the way shaded or 80% shaded. So add and you get 180%

Answer:
A: 82.5
Step-by-step explanation:
Average score of the 4 regular tests = (78 + 72 + 74 + 88)/4 = 78
We are told;
- the regular tests account for 40% of the final grade.
- final exam counts for 20%
- project counts for 10%
- homework counts for 30%
Thus;
weighted mean grade = (40% × 78) + (20% × 79) + (10% × 88) + (30% × 89) = 82.5
6 - 2 x 1
= 6 - 2
= 4
We have to use the PEDMAS method in solving all kinds of calculation expression.
P = Parentheses (or brackets)
E = Exponents (or Index)
D = Division
M = Multiplication
A = Addition
S = Subtraction
