Answer:
the volume of the sphere is 507.78981 cm^3
Step-by-step explanation:
The computation of the volume of the sphere is given below:
Given that
The Diameter is 9.9 cm
So, the volume of the sphere is
= 4 ÷ 3 ×π × r^3
= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3
= 4 ÷ 3 × 3.14 × 4.95^3
= 507.78981 cm^3
Here r denotes the radius
And, the radius would be comes by dividing the diameter from 2
Hence, the volume of the sphere is 507.78981 cm^3
Answer:
C. c = (xv - x) / (v - 1).
Step-by-step explanation:
v = (x + c) / (x - c)
(x - c) * v = x + c
vx - vc = x + c
-vc - c = x - vx
vc + c = -x + vx
c(v + 1) = -x + vx
c = (-x + vx) / (v + 1)
c = (-x + xv) / (v + 1)
c = (xv - x) / (v + 1)
So, the answer should be C. c = (xv - x) / (v + 1).
Hope this helps!
Answer:
a. 8
b. 61, 23, 84
Step-by-step explanation:
As we can see, point S is between points R and T, therefore:
- RS + ST = RT
- 7y + 5 + 2y + 7 = 14y - 28
- 9y + 12 = 14y - 28
- 14y - 9y = 12 + 28
- 5y = 40
- y = 40/5
- y = 8
------------
- RS = 7y+5 = 61
- ST = 2y + 7= 23
- RT = 14y - 28 = 84
Step 1: Simplify both sides of the equation.
2x−3+7x+1=16
2x+−3+7x+1=16
(2x+7x)+(−3+1)=16(Combine Like Terms)
9x+−2=16
9x−2=16
Step 2: Add 2 to both sides.
9x−2+2=16+2
9x=18
Step 3: Divide both sides by 9.
9x
/9 = 18
/9
Therefore, x=2
Answer:
x is 2.
Answer:
isosceles right triangle
Step-by-step explanation:
(1, 1) and (1, 4) are 3 units apart
(1, 1) and (4, 1) are 3 units apart
(1, 4) and (4, 1) are 3√2 units apart
So we have an isosceles right triangle.
