Answer:
V=π*(2x^3+35x^2+176x+192)units^3
Step-by-step explanation:
V=πr^2h
r=x+8
h=2x+3
V=π*(x+8)^2*2x+3
=π*(x^2+16x+64)*2x+3
=π*(2x^3+32x^2+128x+3x^2+48x+192)
=π*(2x^3+35x^2+176x+192)
Volume of the cylinder=π*(2x^3+35x^2+176x+192)units^3
Answer:
26 3/4 as a decimal would be 26.75
HOW TO SOLVE:
1) use x as a variable
2) the starting equation is:
4x + 3x + 5x = 18
3) add all the like terms on the left side of the equation:
12x = 18
4) Divide by 12 on both sides:
x=1.5
5) Find the lengths of the sides:
- 4x = 4(1.5) = 6
- 3x = 3(1.5) = 4.5
- 5x = 5(1.5) = 7.5
SO, the lengths of the sides of this triangle are: 6, 4.5, and 7.5
6x
Step-by-step explanation:
1.2(4x-1)=8x-2=6x
Answer:
3/8 of the day
Step-by-step explanation:
A day is 24 hours
You spend 9 of them sleeping
The fraction you spend sleeping is
9/24
You can simplify the fraction by dividing the top and bottom by 3
9/3 = 3
24/3 = 8
3/8
