Answer:
Step-by-step explanation:
ok look at this in a better way 240 is 2/5 of a pie so add 240 to that and you will get 4/5 to get the last 1/5 split 240 in 1/2 and add it all together so
240+240+120= ?
Answer:
If a certain cone with a height of 9 inches has volume V = 3πx2 + 42πx + 147π, what is the cone’s radius r in terms of x?
Step-by-step explanation:
V = 3πx2 + 42πx + 147π
V=3π(x2 + 14x +49)
9.42(x2 + 14x +49)
9.42(x2 + 14x +14) -14 + 49= 0
9.42(x + 7)^2 + 35= 0
9.42(9.42(x + 7)^2 = - 35)9.42
(x + 7)^2 = - 35/9.42)
√(x + 7)^2=√- 35/9.42
x + 7 = - 1.927
x= - 1.927 - 7
x= - 8.927
V = 3π(- 8.927)^2 + 42π(- 8.927) + 147π
V=750.69 - 1177.29 + 461.58
<u>V=34.98</u>
h= 9 inches
V = 13πr2h
34.98 = 13(3.14) (r^2) (h)
34.98 = 40.82 (r^2) 9
34.98 = 367.38 r^2
34.98/ 367.38 = 367.38 r^2/ 367.38
0.095= r^2
Answer:
1/25
Step-by-step explanation:
The bag has:
- 2 yellow marbles
- 3 red marbles
- 5 blue marbles
- 10 total marbles
The probability of picking a yellow marble is 2/10=1/5.
So, the answer is (1/5)² = 1/25
Answer:
384 square cm
Step-by-step explanation:
Fabric used will be equal to the total surface of the cubical block.
N + (n+1) = 37
n+n + 1 = 37
2n + 1 = 37
2n = 36
n = 18
n+1 = 19
18 and 19
Hope this helps ^_^
