Answer:
A) 3/4
Step-by-step explanation:
Given: Both circle A and circle B have a central angle measuring 50°.
The area of circle A's sector is 36π cm2.
The area of circle B's sector is 64π cm2.
We know, area of the circle=
lets assume the radius of circle A be "" and radius of circle B be ""
As given, Area of circle A and B´s sector is 36π and 64π repectively.
Now, writing ratio of area of circle A and B, to find the ratio of radius.
⇒
Cancelling out the common factor
⇒
⇒
Taking square on both side.
Remember; √a²= a
⇒
⇒
⇒
Hence, ratio of the radius of circle A to the radius of circle B is 3:4 or 3/4.

Answer
Find out the how much weight does she need to remove from her suitcase.
To prove
Let us assume that the weight Clara's need to remove from her suitcase be x.
As given
the airline's weight limit for suitcases is 50 pounds
Than the equation becomes
x = 8.25 pounds.
Therefore the weight Clara's need to remove from her suitcase be 8.25 pounds.
As 1 pounds = 16 ounces
Convert 8.25 pounds into ounces.
x = 8.25 × 16
x = 132 ounces
Therefore the weight Clara's need to remove from her suitcase be 132 ounces.
5/10 + 1/5 = 7/10 Hope this helps
