Answer:
D) 200
Step-by-step explanation:
To find what x equals you have to use the expression:
is over of equals percent over 100
In this problem you are given the percent, 65%, and the is, 130.
So we are trying to find the of so you would substitute of with x.
So 130/x = 65/100
Now you would do Cross Product Property to find x.
So 130*100 = 13000
65*x = 65x
65x = 13000
65/65 = 1
13000/65 = 200
x = 200
So 65% of 200 is 130

The graph of the equations was plotted using geogebra graphing and attached.
Let x represent the hours weightlifting and y represent the hours doing cardio exercises.
Since he spend a maximum of 20 hours, hence:
x + y ≤ 20 (1)
Also, he spends at least 8 of those hours weightlifting, hence:
x ≥ 8 (2)
He wants to spend no more than 15 hours doing cardio exercises, this is:
y ≤ 15 (3)

Answer:
The beam should be placed 8 feet from the center.
Step-by-step explanation:
The struts are y = √(x + 8) and y = √(x − 4). The struts are 2 feet apart at the location of the beam:
√(x + 8) − √(x − 4) = 2
Solving:
√(x + 8) = 2 + √(x − 4)
x + 8 = 4 + 4√(x − 4) + x − 4
8 = 4√(x − 4)
2 = √(x − 4)
x − 4 = 4
x = 8
