The answer is the first choice because it is on google.
15. x ≤ -24
x + 19 ≤ -5
x ≤ -24
16. z > -12
3z > -36
z > -12
17. 185 + c > 410; c > 225
18. C.
x - 6 ≥ 1
x ≥ 7
5z^2 + 16
a coefficient is a number multiplied by a variable (a letter). so there is only ONE coefficient in this expression and it is 5.
Answer:
37.68 units³
Step-by-step explanation:
To calculate the volume of a cone, the formula is:
V = π x r² x ( h / 3 )
Simply input the corresponding numbers into the equation:
V = π x ( 2 )² x ( 9 / 3 )
V = π x 4 x ( 3 )
V = π x 12
V = 3.14 x 12
V = 37.68 units³
If we use 3.14 for pi, the answer comes out to 37.68 units³
X2 - 25 = 0
Add 25 on each side.
x2 = 25
Divide by 2 on each side.
x = 12.5
