Answer:
1st multiply g and f then h
Answer:The larger is 28, the smaller is 9.
Step-by-step explanation:
n = the smaller
3n + 1 = the larger
n + (3n + 1) = 37
4n + 1 = 37
4n = 36
n = 9
3n + 1 = 3(9) + 1 = 28
The larger is 28, the smaller is 9.

Answer:
81.75 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A =
h (a + b)
where a, b are the parallel bases and h is the perpendicular height
Calculate h using the right triangle and the sine ratio
sin30° =
= 
Multiply both sides by 10
10 × sin30° = h, thus
h = 5
a = 12 and b = 8.7 + 12 = 20.7, hence
A =
× 5 × (12 + 20.7)
= 0.5 × 5 ×32.7
= 81.75 ft²
Answer:
6. c. 120
7. $6.45
Step-by-step explanation:
1. 150 x 0.20 = 30
2. 150- 30= 120
1. 43 x 0.15= 6.45
