You could understand the ration as parts: the total number of parts was 3+7=10.
So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).
so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
Since 90 degree is 1/4 of a circle, the area will be 1/4 th area of the full circle.
The radius is given by, r = 8 ft, therefore, the area of the full circle is,
Therefore, the area of the sector is,
Answer:
B) 2
C) y = 2x
Step-by-step explanation:
Part B
Constant is 2 because in order to get x to the value of y, you must multiply by 2.
Part C
y = 2x
