So 20=80%'
% means out of 100 so
80%=80/100 so
20=80/100
we try to get to 100/100 so
20=80/100
5=20/100
5 times 20=100 so
25=100/100

She bought 2 1/4 more blue ribbon.
4 3/8 - 2 1/8 = 2.25
2.25= 9/4
9/4= 2 1/4

For this case we must indicate the cosine of A, of the figure shown. By definition:

Substituting the values we have:

So, we have to:

Answer:
Option D
Answer:
I'm not good with the type of math on 3, so I'm going to answer 4. (P.S I don't know the question you're asking, so I'm going to assume you want to know the area and perimeter of the shapes.
Step-by-step explanation:
To solve number 4 I added the width of the 2 triangles to give me the width of the rectangle, so then 2 times 9 is 18. Then for the triangles. The formula for triangles is base times height divided by 2. So we add the areas of all shapes and we get: 18+6+24=48m. So the area for number 4 is 48 meters.
(hope this was your question)
