Gabrielle took a Spanish test with 50 questions. She answered 50 questions but only answered 44 of them correctly. What percent of the questions did Gabrielle answer correctly?
The fraction represents the 44 questions that Gabrielle got correct out of the 50 questions she answered altogether.
To find out what percent of questions Gabrielle answered correctly, we can turn into a percent.
We can first reduce the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 44 and 50 using 2.
44 ÷ 2 = 22
50 ÷ 2 = 25
22 ÷ 25 = 0.88
0.88 × 100 = 88%
Therefore, Gabrielle answered 88% percent of the questions correct on her Spanish test.

Answer:
B.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
As given in the question, we know that:
The ratio of the area of the circle to the area of the square is π/4
- The formula to find the volume of the cone is:
V = 1/3*the height*the base area
<=> V1 = 1/3*h*π
- The formula to find the volume of the pyramid is:
V2 = 1/3*the height*the base area
<=> V = 1/3*h*4
=> the ratio of volume of the cone to the pyramid is:
=
= (1/3*h*π ) / ( 1/3*h*4
)
= π/4
S we can conclude that the volume of the cone equals π/4 the volume of the pyramid
Hope it will find you well.
