Answer:
x=8
Step-by-step explanation:
Make all the denominators the same
3(x-4/10)=6(3/5)-2(x-5/15)
(3x-12)/30=18/30-(2x-10)/30
Cancel out all the denominators because they're the same
3x-12=18-2x+10
3x-12=28-2x
Add 12 to both sides
3x=40-2x
Add 2x to both sides
5x=40
Divide both sides by 5
x=8
Answer:
0.098 , 0.89, 0.98
Step-by-step explanation:
0.098 is the smallest, 0.98 is the closest to 1 so it's the biggest
Answer:
Radius = 6.46 meters
Height = 1.46 meters
Step-by-step explanation:
The volume of a cylinder = πr²h
In the above question, we were given
r = (x + 5) meters
h = x meters
Volume = 192 cubic meters
Hence,
192 = π × (x + 5)² × x
192 = π × (x² + 10x + 25) × x
192 = π × (x³ + 10x² + 25x)
Divide both sides by π
192/π = x³ + 10x² + 25x
61.115498147 = x³ + 10x² + 25x
x³ + 10x² + 25x - 61.12
This Quadratic equation is a polynomial
x = 1.46119
From the above:
Radius = (x + 5)meters
Radius = 1.46119 + 5 = 6.46119 meters
Approximately to 2 decimal places = 6.46 meters
Height = x meters
Height = 1.46119 meters
Approximately to 2 decimal places = 1.46 meters
There are no real solutions to that equation.
