The 15.867 pounds of her weight is fat.
It is required to find how many pounds of her weight is fat.
<h3>What is percentage?</h3>
A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.
Given that:
Percent or percentage or %means "per 100" or "out of 100". Therefore
12.3%=12.3/100
So 12.3% of 129 pounds is:
=12.3/100*129
=1586.7/100
=15.867
Therefore, the 15.867 pounds of her weight is fat.

Answer: Construction and Engineering
Answer:
Step-by-step explanation:
In Problem 6, 3/x = tan 30 degrees, or x/3 = 1 / (tan 30 degrees), or
x = 3 / (tan 30 degrees). Using a calculator: x = 3 / (0.449) = 6.68 units
In Problem 9, we begin by finding the length of the hypotenuse of the upper triangle: sin 60 degrees = 9√3 / hypotenuse, or
hypotenuse = 9√3/ (√3 / 2) = 9/2. Then the hypotenuse of the 45-45-90 triangle is 9/2. Thus, cos 45 degrees = x / (9/2), or
2x √3
---- = -------
9 2
9√3
Cross-multiplying, we get 4x = 9√3, so that x = -------------
