X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
Answer:
Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Step-by-step explanation:
4 hours? i may be wrong
i did - 60 * 15
seems about right, since 50% would be 7.5 hours?
The formula to calculate the volume of a cone is:

So, replace radius = 3in and h = 8 in.
The result is: [1/3] π (3in)^2 (8in) = [1/3]π(9)(8) in^3 = 24 π in^3
Answer: option b. 24 π in^3
Answer: 234
Step-by-step explanation: 78 * 3 = 210 + 24 = 234
