gallons of paint was used by Lucy.
Step-by-step explanation:
29/12 = 2 5/12
X = 1.5 times (150-x)
x = 225 -1.5x
2.5 x = 225
x= 90
The more expensive book was $90
Check your answer:
x = 1.5 times (150-x)
90 = 1.5 times (150-90)
90 = 1.5 x60
90=90
Answer:

Answer:
Hi there!
The correct answer is: 220.5 cm²
Step-by-step explanation:
This is an example of a composite figure where you have to break up the figure into different shapes. In this case this figure, can break up into a semicircle and a triangle.
<u>Triangle:</u> A= 1/2bh A=1/2(16)(15) = 120 cm²
<u>Semicircle: </u>another way of saying half a circle so A= 1/2 πr²
A=(1/2)(π)(8)² = 100.5 cm²
And then you just add the two areas together and you get 220.53 cm²
