From the following figure:
Because the center angle measure 45 degrees, we must rotate 3 times 45 degrees to get point D.
In other words, we must rotate
that is 135 degrees clockwise.

Method 1: Creating and Solving Equations</h2>
Step 1: Find the amount drilled per hour
To do this, we have to divide the amount drilled by the number of hours it took to drill and find how much is being drilled per hour.
(I know it's a mouthful)
-72ft = 24x, where x is the amount drilled per hour
-72ft ÷ 24 = x
-3ft = x
-3ft per hour
Step 2: Find how many hours it takes to drill to -132 ft
Since we know the rate of drilling per hour, we can divide the target amount by the amount drilled per hour
-132 ÷ -3 = y, where y is the number of hours it takes
44 = y
y = 44
It will take a total of 44 hours to drill to -132 ft
<h2>Method 2: Proportions</h2>
We can set up a proportion like this, where we know that it takes 24 hours to drill 72 ft, but we don't know how long it takes to drill 132 feet
Cross multiply
Simplify
Divide both sides by -72
It will take a total of 44 hours to dig to -132 ft

Okay. So the bill was a total of $725, with 6% sales tax added. To find the amount of sales tax, all you have to do is multiply the amount on the bill by the percentage of tax. 725 * 6% (0.06) is 43.5. There. The sales tax was $43.50.
Answer:
1. 18 eggs is $3.06
2. 3 pounds is $4.47
3. If his drawing is 8 inches long it will be 6 inches wide
Step-by-step explanation:
12 eggs is $2.04 so half of 12 is 6 so half of 12 eggs would be $1.02 so 18 eggs is $3.06
Answer:
<4 = 22
Step-by-step explanation:
<4 = x
x + 158 = 180
x = 22
