Hello help me out thank you !
Answer:
1130.4
Step-by-step explanation:
The volume of a cylinder is πr^2h, where r is the radius and h is the height.
We are given the height, 10m.
The diameter is 2m more than the height, so 2+10=12m.
The radius is half the diameter, so 12m/2=6m.
Use r=6 and h=10 in the formula to get the volume
π6^2*10≈1130.4

If you were to solve the following system using substitution, your new equation would be...
Answer:
2x+ (x-1) = 8
Simplified
3x-1 =8
Step-by-step explanation:
y=x−1
2x+y=8
Take the first equation and everywhere you see y in the second equation substitute x-1
2x+ (x-1) = 8
You can simplify
2x+x-1 =8
3x-1 =8
If you want to solve
3x-1+1 =8+1
3x= 9
Divide by 3
3x/3 =9/3
x=1
Then solve for y
y = x-1
y = 3-1
y=2
Enter the opposite of 4/5 and negitive 7/15
Answer:

Jen has 13 fewer marbles than Marty. She has 20 marbles. Which equation can be
solved to find how many marbles Marty has?
F
13 m - 20
H
13m - 20
G
m 13 - 20
3
m - 2013
20-13=7
so i think the answer would be m 13-20?

I need help on this problem.
Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2
