You add 70,50, and 90 together then you do seperately 30, and80 (add) lastly take that amount then divide that by your first sum
Answer:
C. 2
Step-by-step explanation:
.4minute :
V=πr²h
V=π(1.8/2)²(3.5ft)=.9639ft³×1min/2.3ft³=.419 min
Answer:
that would be 39 minutes
Step-by-step explanation:
Answer: 252
Explanation:
First we need to find y.
Because there are three marks indicating that the measure of the angles are congruent, we know that all sides of the triangle are equal, so we can use that to find y.
5y-6=4y+12
y=18
Now substitute y into all the side equations:
5y-6 = 5(18)-6 = 84
4y+12 = 4(18)+12 = 84
6y-24 = 6(18)-24 = 84
Now that we know all the sides, just add these values together to get your perimeter:
84+84+84= 252
