Answer:
The area of the baseboard is 
Step-by-step explanation:
We have,
Length of the bed, l = 15 m
Width of the bed, b = 9/10 m
It is required to find the area of the baseboard. It is a shape of rectangle. The area of a rectangular shape is given by :

So, the area of the baseboard is 
Angle ABC is an inscribed angle so would be half of the arc.
So, 4x-5.5=1/2(5x+25)
4x-5.5=5/2x+25/2
4x-5.5=2.5x+12.5
4x-2.5x=12.5+5.5
1.5x=18
x=12
So angle ABC=4(12)-5.5=48-5.5=42.5
Arc AC=5(12)+25=60+25=85
Check: 42.5(2)=85
Answer: Arc AC is 85
Answer:
written below for problem #2
Step-by-step explanation:
a. ratio is 12:40 since they're are 12 non fiction and 40 graphic novels
b. 40:12 (same reasoning as part a)
c. 6:40 for the ratio of science fiction to graphic novel, 12:6 for the ration of non fiction to science fiction, x:6 for the ratio of the unknown amount of fiction books to the science fiction books. (x is just there as a variable so it just represents fiction books)
