I am guessing your question is <span>A row of plaques covers 120 square feet of space along a wall. If the plaques are 3 feet tall, what length of the wall do they cover?
I know the answer to this question because i had to do this for a test before. and the answer is that it covers 140 ft of the wall</span>
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10
The volume of the right circular cylinder is 31064.54 cm³.
What is the formula for the volume of cylinder?
Formula:
V = πr²h.............. Equation 1
Since,
V = Volume of the right circular cylinder
r = radius of the base of the cylinder
h = height of the cylinder.
We have given that,
r = 46.25/2 = 23.125 cm
h = 18.5 cm
π = 3.14
We have to calculate volume of right circular cylinder.
Therefore,
Substitute these values into equation 1
V = 3.14(23.125²)(18.5)
V = 31064.54 cm³
Therefore
The volume of the right circular cylinder is 31064.54 cm³.

Answer:
5/11
Step-by-step explanation:
let x=0.4545...
100x=45.4545...
100x-x = 99x=45.4545... - 0.4545...=45
x=45/99=5/11
