Answer:
The individual has 36.09 pounds of body fat.
Step-by-step explanation:
Given that an individual has a body fat percentage of 19.3% and weighs 187 pounds, to determine how many pounds of her weight is made up of fat the following calculation must be performed:
(187 x 19.3) / 100 = X
3.609.1 / 100 = X
36.091 = X
Therefore, the individual has 36.09 pounds of body fat.
Answer:
Step-by-step explanation:
The range of a function y = f(x) is the set of values y takes for all values of x within the domain of f. The graph of any quadratic function, of the form f(x) = a x2 + b x + c, which can be written in vertex form as follows. f(x) = a(x - h)2 + k where h = - b / 2a and k = f(h) is either a parabola opening up, when a > 0, or a parabola opening down, when a < 0
Combine like terms (2x-3x=-x) then you're left with -x+6=5x-9. Get the X's on one side and the numbers on one side (-x+x=0, 5x+x=6x) (-9+9=0, 6+9=15) then you're left with 6x=15. Simplify and you have your answer
(a) 85% of 60 = 0.85 x 60 = 51
Answer: (a) 51
(b) 25% = 18
1% = 18 ÷ 25 = 0.72
100% = 0.72 x 100 = 72
Answer: (b) 72
