Answer:
6174π
Step-by-step explanation:
The equation for a whole sphere is 4/3 π(r)³
Given the diameter of 42, we can conclude that the radius would be 21
Next, we would plug in these variables and get 4/3 π(21)³
Simplify all of this down and you would get 12348π
Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π
Divide that by 2 and you get 6174π
Hope this helps! :)
Answer:
True
Step-by-step explanation:
if you really think about it you can use y for anything an dy is the most replaceable to have so i agree with your think hope it help man
Answer:
2.3p – 10.1 = 6.49p – 4
230p – 1010 = 650p – 400 – p
Step-by-step explanation:
……………………………………………
2.3p – 10.1 = 6.5p – 4 – 0.01p
⇔ 2.3p – 10.1 = (6.5p – 0.01p) – 4
⇔ 2.3p – 10.1 = (6.5 – 0.01)p – 4
⇔ 2.3p – 10.1 = (6.49)p – 4
⇔ 2.3p – 10.1 = 6.49p – 4

2.3p – 10.1 = 6.5p – 4 – 0.01p
⇔ 100 × (2.3p – 10.1) = 100 × (6.5p – 4 – 0.01p) <u><em>multiply both sides by 100</em></u>
⇔ 100 × (2.3p – 10.1) = 100 × (6.5p – 4 – 0.01p)
⇔ 230p – 1010 = 650p – 400 – p
……………………………………………………
x= 0, -7
the reason that is true is because if you set each x equal to each other, you get x = 0 and x + 7 = 0 and if you subtract 7 on both sides you get x = -7
so x = -7, 0
Right triangle
Use Sohcahtoa
Given hypothenuse = 10
Adjacent = x
And angle degree of 52
You can use Cosine
Cos(52) = x/10
0.6156614753 = x/10
x = 6.156614753
Round to nearest tenth
Solution: 6.2
