Answer:
200 sheets are required
Step-by-step explanation:
We need to calculate the area of both the sheets and the wall
Mathematically,
area of a rectangle = l * b
Area of the sheet = 20 * 50 = 1,000 cm^2
100cm = 1 m
so the area of the wall is 400 by 500 = 200,000 m^2
To know the number of sheets, we now divide the area of the wall by that of the sheet
Mathematically, that will be;
200,000/1,000 = 200 sheets

Reduce a ratio 3/4in: 3/16 ft
Answer:
4in : 1ft
Step-by-step explanation:
We start with:
3/4 in = 3/16 ft
This means that the length of 3/4 inches is the same as the length of 3/16 feet.
To reduce this, we can start by dividing by 3 in both sides of the equation:
(3/4)/3 in = (3/16)/3 ft
1/4 in = 1/16 ft
Now we can multiply both sides by 16:
16/4 in = 16/16ft
4 in = 1ft
now we reduced the ratio to:
4in : 1ft

Find the value of.x, then y. Write your answer as an ordered pair.
If y = 3x – 8, and y = f(x), find f(2). *
Answer:
f(2) = -2
Step-by-step explanation:
Replace y with f(x). The equation is now f(x) = 3x - 8. f(2) means that you replace all of the x’s with 2’s. Bringing the equation to f(2) = 3(2) - 8. You now just have to solve the equation. f(2) = 6 - 8. f(2) = -2

Is 12x^2 a factor of 6x
Answer: 12x^2 is 144 because 12 times 12 is 144 which means 6 does not include with those so no 6 is not a factor of that
Step-by-step explanation:
Tell whether the ordered pair is a solution to the inequality.
Answer:
If an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.

solve for k
9/10 = 10/k
Answer:
k = 100/9
Step-by-step explanation:
In this question, we will be solving for "k".
Solve:
9/10 = 10/k
Cross multiply.
(9 · k) = (10 · 10)
9k = 100
Divide both sides by 9
k = 100/9
Your answer would be k = 100/9
What is the solution to the system?
Answer:
(1, 3)
Step-by-step explanation:
The solution to these kinds of graphs is where the 2 lines intersect, in this case they intersect at (1, 3), so (1, 3) is the solution

I don’t know how to do this I’m so confused
Answer:
You have to graph it
Step-by-step explanation:
Step-by-step explanation:
take the value in that BIG curly bracket as X terms....then substitute one by one to the equation given below to get Y values...after that u have cordinates then u can draw the graph..
[tex]x \: \: \: y \\ - 2 = - 8 \\ - 1 = - 10 \\ 0 = - 12 \\ 1 = - 14 \\ 2 = - 16[/tex]
this is for the first equation..so the coordinated are...
(-2,-8), (-1,-10), (0,-12), (1,-14), (2,-16)
use the same methord to find the others
