Answer:

x ≈ 60.6°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{IJ}{HI} = \frac{3.9}{2.2} , then

x = tan^{-1} (\frac{3.9}{2.2} ) ≈ 60.6° ( to the nearest tenth )

$1.88 is our amount after the 380% is added! 

$1.88 - 380%*x = x

Note, that when you are working with percents in a problem you need to convert the percent into a decimal value in order to properly work with it in an equation like the one above. 

So, it will look like this: 

$1.88 - 3.8x = x

Now onto explaining how I derived this equation in the first place, because it doesn't help you if you don't know how to do it yourself. 

How a percent problem works is if you are taking some original price x, and increasing it by 380% you would take 380% of the item, and then adding it to the item. To take 380% of an item you would need to multiply the number by 380% (3.8). So, if you translate that into math it looks like this: 

x + 380%*x = y

Y, in this case is $1.88. In other words it is the price AFTER you've added 380% to the cost. So I started to solve for x by subtracting 380%*x on both sides leaving us with this: 

$1.88 - 3.8x = x

We need to solve the equation for x by adding 3.8x on both sides. 

$1.88 = 3.8x + x

Combine like terms. 

$1.88 = 4.8x 

Divide both sides by 4.8. 

$1.88/4.8 = x 

So our original price is $1.88/4.8! 

The question asks for the 380% * x part of the problem. 

So we take our answer and multiply it by 3.8. 

($1.88/4.8)*3.8 = $1.49 mark up!

NEED ANSWER ASAP- FOR FINALS
blagie [28]

Answer:

Width - 12ft  Length - 30ft

Step-by-step explanation:

Width is 12ft

Length is 30ft

Depth is 6ft

The length, 30ft, is 2.5 times longer than the width which is 12 ft which confirms the two dimensions to be correct.

When you multiply all three of the dimensions of the swimming pool you will get 2940 cubic feet
