Hello!
Let's follow the BEDMAS rule.
First we should do everything inside the brackets. According to BEDMAS we should do multiplication first before subtraction:
(28 × 5 - 5 × 190)
28 × 5 = 140
5 × 190 = 950
(140 - 950) = -810
So now we have:
(-810 - 2 × 5^-2) / 2^3
Next, we do exponents so:
5^-2 = 1/25
2^3 = 8
(-810 - 2 × 1/25) / 8
(-810 - 2/25) / 8
(-20252/25) / 8 = -5063/50
So now we have:
(-5063/50)^4 × 288
If we plug the first term into a calculator and out it to the party of 4, we get:
105136058.7
So that number times 288 we get:
3.03x10^10 as the Correct Answer

Answer:
x => y
0 => 0
2 => 3
4 => 6
-2 => -3
Step-by-step explanation:
The equation of a proportional relationship is represented as y = kx,
where, k = y/x
We are given that k = ³/2
This means that, equation of the relationship therefore would be:
y = ³/2x
Use this equation to solve for each missing value on the table given:
✔️Where, y = 0, substitute y = 0 into y = ³/2x to find x:
0 = ³/2x
0 * 2 = 3x
0 = 3x
0/3 = x
x = 0
✔️Where, x = 2, substitute x = 2 into y = ³/2x to find y:
y = ³/2(2)
y = 3
✔️Where, y = 6, substitute y = 6 into y = ³/2x to find x:
6 = ³/2x
6 * 2 = 3x
12 = 3x
12/3 = x
x = 4
✔️Where, x = -2, substitute x = -2 into y = ³/2x to find y:
y = ³/2(-2)
y = -3
A) 2L + 2W = 48
B) L * W = 140
B) W = 140 / L
Inputting this to equation A)
A) 2L + 2*(140 /L) = 48
L + 140/L = 24
Multiplying both sides by "L"
L² + 140 = 24L
L² -24L +140 = 0
(L -10) * (L-14) = 0
L= 10
L = 14
If length = 10 then width =14
If length = 14 then width = 10
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
