D. 36 cm that’s how I got my answer
<span>A. 16 for every 100
B. 8 for every 50
C. 1 for every 6.25
D. 0.5 for every 3.125</span>
First we use our order of operations PEMDAS. So parentheses is first. 8-3 = 5.
Here is the new equation. 9 - 5 ÷ 5 × 2 + 6. Next we divide. 5 ÷ 5 = 1. Next is multiplication. 1 x 2 = 2. Now we have 9 - 2 + 6. 9 - 2 + 6 = 13
So the answer is 13, I hope this helps!
X^(3/5) = 1.84
x^(3/5) = (1.84)
Raise both sides of the equation to (5/3).
This is so that on the side with x, 3/5 * 5/3 = 1.
(x^3/5 )^5/3 = (1.84)^(5/3)
x^(3/5 * 5/3) = 1.84^(5/3)
x^1 = 1.84^(5/3)
x = 1.84^(5/3)
But remember we are solving for x^2.
x = 1.84^(5/3)
x^2 = (1.84^(5/3))^2
x^2 = 1.84^(5/3 *2 )
x^2 = 1.84^(10/3)
Use a calculator here.
x^2 = 1.84^(10/3) ≈ 7.63
Option A.
Cheers!
