Answer:
I think it's
D. AC/GI = BC/HI
Step-by-step explanation:
Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.
AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.
I think.
I guess.
I don't know.
I didn't pay attention, tbh. LOL

I don't see any relationship between the expression you have shared and the volume of paper towels.
If you wish to simplify the given expression, factor out 28, obtaining
28*pi(49 - 5.0625) = 28*pi*(43.9375).
You could leave your answer as shown, or you could multiply it out. Try several forms of presentation. Which one is closest to the answer to this problem?
A rug maker is using a pattern that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in the length and width. Write and simplify an expression for the perimeter of the new pattern.
p=2(96+l)+2(60+w)
This is the equation. p is for perimeter. (96+l) represents the original length plus the change in length. The 2 before (96+l) represents that there is one length on each side of the rectangle.
Same for the width. (60+w) represents the original width plus the change in width. The 2 before (60+w) represents that there is one width on each side of the rectangle.
The simplified equation is p=(192+2l)+(120+2w) (this is your answer)
I hope this helps!
Answer:
7 rpm = 0.73 rad/s
Step-by-step explanation:
R = Radius of merry-go-round = 1.8 m
= Moment of inertia of merry-go-round = 255 kg m²
= Moment of inertia of child
ω = 9 rev/min
m = Mass of child = 24 kg
From the conservation of angular momentum
∴ New angular speed of the merry-go-round is 7 rpm =
