Answer:
A = 114 m²
Step-by-step explanation:
The formula for area of a trapezoid is
A = (1/2)(B + b)h where B is the bottom base, b is the top base, and h is the height.
We are given B = 11, b = 8, and h = 12, plug those values in and simplify
A = (1/2)(11 + 8)(12)
A = (1/2)(19)(12)
A = (19)(6) (half of 12 is 6)
A = 114 m²

Just need to convert the mass of moon in terms of 10^24. So shift over 2 decimal places.
5.97 x 10^24 + 0.0734 x 10^24 = 6.04 x10^24
The nickels in the envelope is $0. 12
<h3>How to determine the number</h3>
From the information given, we have that;
Dimes + nickels = $1. 20
1/4 dimes + dimes = $ 1. 35
Let dimes = d
Nickels = n
d + n = 1. 20 equation a
d/4 + d = 1. 35 equation b
Make 'd' subject from equation a
d = 1. 20 - n
Substitute into equation b
1. 20 - n/ 4 + 1. 20 - n = 1. 35
0. 3 - 0. 25n + 1. 20 - n = 1. 35
collect like terms
- 1. 25n = 1. 35 - 1. 5
- 1. 25 = - 0. 15
n = -0. 15/ -1. 25
n = 0. 12
Thus, the number of nickels in the envelope is $0. 12
