6x + 7 = 8x - 15
7 = 2x - 15
22 = 2x
11 = x
Answer- 971.76 yd^3 (btw I used pi not 3.14)
Explanation:
Solve for the volume of the cone
V=pi*r^2*h/3
V=pi*10^2*22/3
V= 2408.55
Next solve for the volume of the sphere
V=4/3*pi*r^3
V=4/3*pi*7^3
V=1436.76
The last step it to subtract the volume of the sphere from the volume of the cone
2408.55-1436.76=971.76

Answer:
The midpoint is (3, 3).
Step-by-step explanation:
We are given the two points A(9, 11) and B(-3, -5).
The midpoint is given by:
So:
The midpoint is (3, 3).
We want to show that AM = MB.
We can use the distance formula:
The distance between A(9, 11) and M(3, 3) will then be:
And the distance between B(-3, -5) and M(3, 3) will be:
So, AM = MB = 10.
Since AM = MB = 10, AM + MB = 10 + 10 = 20.
So, we want to prove that AB = 20.
By the distance formula:
Answer:
The afternoon temperature is
5°
Step-by-step explanation:
Step one:
given data
the morning temperature= -15°
the afternoon temperature rose by 20°
Required
The afternoon temperature
Step two:
Hence the afternoon temperature is given as
=-15°+20°
= 5°
