1. You are given PR and RS, so simply add the two measurements to get PS.
28.2+30.7= 58.9
2. Subtract QV from QT to get TV.
78-56= 22
3. Again, Subtract QV from QT to get TV.
74-36= 38
4. Similar to question 1, add PR and RS to get PS.
40+53= 93
The Pythagorean theorem can be used to find the length of the diagonal (d) of a square.
d² = (3√2)² + (3√2)² = 18 + 18 = 36
d = √36 = 6
The measure of the diagonal is 6.
You already have the answer
Present value, P = 20
compounding interest per 6 months, i = 0.025/2 = 0.0125
Number of periods, n = 30*2 = 60 (half-years)
Future value in 30 years
=P(1+i)^n
=20(1.0125)^60
= $42.14
