1 7/8
She ate 3/8 quarts of soup.
There are 2 1/4 quarts of soup.
So in order to solve it, you must make both denominators equal.
The GCF is 8, so 4×2=8
You must do the same with the nominator as well.
So, 1×2=2
Since 3/8 is bigger than 2/8, you must use a whole number. Lets take one.
It then becomes 1 10/8.
1 10/8 - 3/8= 1 7/8
Therefore, the answer is 1 7/8

Answer:
x = 40°
Step-by-step explanation:
The base angles of the triangle are 71° and 69° ( vertical angles ) , then
x = 180° - (71 + 69)° = 180° - 140° = 40°
The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= 
Where r is the radius of the circle.
Given :
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
SA= 
The total surface area of this sphere is 400π .
