1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Next, you would cross multiply.
185x = 3,500
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185.
x = <span>
18.918%Your answer was correct!
2) </span>First, you would need to create an equation for this problem. Let x represent the unknown 85%.

<span> = </span>

<span>
</span>Next, you would cross multiply.
100x = 16150<span>
</span>Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100.
x = 161.53) First, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Next, you would cross multiply.
128x = 2,400
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128.
x = 18.75%I hope this helps!

Answer:
b = -0.0012a +211
208.36 °F at 2200 ft
Step-by-step explanation:
We are given two points:
(a, b) = (8100, 201.28) and (4300, 205.84)
The slope of the desired line can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (205.84 -201.28)/(4300 -8100) = 4.56/-3800 = -0.0012
The "y-intercept" of the function can be found from ...
y-intercept = b -ma
y-intercept = 201.28 -(-0.0012)(8100) = 211.00
So, the function of interest is ...
b = -0.0012a +211
__
At 2200 ft, the boiling point is ...
b = -0.0012×2200 +211 = -2.64 +211 = 208.36
The boiling point of the liquid at 2200 ft is 208.36 °F.

XY = √53
Step-by-step explanation:
Choose which is point 1 and point 2 so you don't confuse the coordinates.
Point 1 (–4, 0) x₁ = –4 y₁ = 0
Point 2 (3, 2) x₂ = 3 y₂ = 2
Use the formula for the distance between two points.




Therefore the line of segment XY is √53.
There are 145 total pieces . you must first convert 20% to a decimal by placing a decimal point two places from the right. 20% = .20
then you mulitiply 145 x .20 = 29
So, Cathy owns 29 pieces of yellow clothing.
