You are X, if your friend is 1.2 times taller than you= 1.2X
That's why 64.5=1.2X
X=53.75
But you should write 53.8 inches tall. Because there is one number after point.
<span>As a result, you are 53.8 inches tall

The answer is B: <span> a^12/b^6
Proof:
Simplify the following:
(a^4/b^2)^3
Multiply each exponent in a^4/b^2 by 3:
(a^(3×4))/((b^2)^3)
3×4 = 12:
a^12/(b^2)^3
Multiply exponents. (b^2)^3 = b^(2×3):
a^12/b^(2×3)
2×3 = 6:
Answer: a^12/b^6</span>
How to solve: 20^2+5^2=x^2, then you take the square root, therefore x=20.62
Answer:
D
Step-by-step explanation:
The formula for the circumference of a circle is 2
r. So if we know that C=60then we can trace our steps back. We are given that pi remains constant so we are left with the 2r from the formula and a 60. 60/2 =30.
The radius is 30cm
A. 3.45%
The formula for a proportion is x/n, "n" is the total of objects and "x" is the number os successes. In this case "defective" is the success because you want to know the percentage for defective parts, so 4/116= 0.0345 and you have to multiply the result by 100 and you get your answer in percentage.
