Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos
=1
Divide both sides by two to get it into the form.
cos= 
Now, on your calculator, use the inverse of cos, to solve for .
= 
( )
= 60
Now you want to find x, so multiply both sides by 2.
x = 60 * 2 = 120
x can have many solutions; however, I have only given you one.
Answer:
huh? explain better
Step-by-step explanation:
B........................
If you would like to know the total value of the liquid in the container, you can calculate it using the following steps:
A cone:
a radius (r) ... 1 in.
a diameter ... 2 in.
a height (h) ... 9 in.
<span>π ... 3.14
</span>
Cone volume formula:
V = 1/3 * π * r^2 * h
V = 1/3 * 3.14 * 1^2 * 9 = 1/3 * 3.14 * 1 * 9
V = 9.42 cubic inches
$2 ... 1 cubic inch
$x = ? ... 9.42 cubic inches
_______________________
2 * 9.42 = 1 * x
x = 2 * 9.42
x = $18.84
The correct result would be $18.84.
