Answer:
Step-by-step explanation:
1. 12
2. 12/3.5 = 3.43
3. 12/15 = 0.8
4. 3.43/0.8
5. 315/x
6. 315/x = 0.8/3.43
7. (315)(3.43) = 0.8x divide both sides by 0.8, so x = 1,350.5625 feet.
Answer:
36 centimeters
Step-by-step explanation:
always start with the bigger number first then divide 72 ÷ 2 = 36 then divide 72 ÷ 36 = 2 then the actual building will be 36
<u>Answer</u>
y⁻¹ = ∛(4x+8)
<u>Explanation</u>
y=(1/4)x³ - 2.
To find the inverse of this equation, you first make x the subject of the formular.
y=(1/4)x³ - 2
Multiply both sides by 4;
4y = x³ - 8
Add 8 on both sides of the equation;
4y + 8 = x³
x³ = 4y + 8
Apply the cube root on both sides to get the value of x;
x = ∛(4y+8)
The inverse of y=(1/4)x³ - 2 is;
y⁻¹ = ∛(4x+8)
