Answer:
131.25
Step-by-step explanation:
There are 3 trapezoids that you need to find its area, all the areas are the same.
Area of trapezoid:
A=(a+b)/2*h
a = 20
b = 15
h = (20-15)/2 = 5/2
A = (20+15)/2*5/2
A = 43.75
3A (3 gardens) = 131.25

Answer:
1.65 + 0.09s
Step-by-step explanation:
Given that :
Cost of speaker = $22
Cost per song = $1.25
Sales tax rate = 7.5%
Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)
Expanding the expression :
0.075(22 + 1.25s)
(0.075 * 22) + (0.075 * 1.25s)
1.65 + 0.09375s
Rounding to the nearest hundredth :
Sales tax on entire purchase :
1.65 + 0.09s
It's given in the question,
- Bianca works as a content writer for $10 per hour.
- She works as a library assistant for $14 per hour.
She worked for a combined total of 75 hours for both the jobs this month.
Let c be the number of hours Bianca worked as a content writer.
Her earning for this month as a content writer = $10c
Her working hours as library assistant this month = (75 - c) hours
Therefore, her earning as a library assistant for the month = $14(75 - c)
By adding the earnings as a library assistant and a content writer for the month = $10c + $14(75 - c)
= (10c - 14c) + 1450
= $(9c + 1050)
Therefore, expression for the combined total amount she earned this month will be $(9c + 1050).
