Answer:
x= -6
Step-by-step explanation:
3(x+5)÷(-3)= 3÷(-3)
x+5= -1
x= -1-5= -6
x= -6
Answer:
V = 1250π/3 mm³
V = 1309 mm³
Step-by-step explanation:
The composite figure is made up of a cylinder with radius 5 mm and two hemispheres of radius 5 mm. The height of the cylinder is
20 mm - 5 mm - 5 mm = 10 mm
The two hemispheres make up a full sphere of radius 5 mm.
V = πr²h + (4/3)πr³
V = π(5 mm)²(10 mm) + (4/3)π(5 mm)³
V = [(25 mm²)(10 mm) + (4/3)(125 mm)³]π
V = [250 mm³ + 500/3 mm³]π
V = 1250π/3 mm³
V = 1309 mm³
Answer:
9 cm
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the side of the cube
Given V = 729, then equating gives
s³ = 729 ( take the cube root of both sides )
s = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
= 9
