27p4-27p2-12p+12/p
Step-by-step explanation:
2x-y=1 is also equal to y=2x-1 so then plug in 1 or x and so on to create a table
<h3>
Answer: 116.2°</h3>
Work Shown:
The first equation is one of the three variations for the Law of Cosines.
Make sure your calculator is in degree mode.
To solve this problem you must apply the proccedure shown below:
1. You have that:
<span> - The scale model is 11 inches long and 8.5 inches wide.
- The door to her room takes up 1.75 inches.
- The longest wall in Jessica’s actual room is 15 feet long.
2. Therefore, the actual size of the door is:
15 feet=180 inches
1.75 inches(180 inches/11 inches)=28.63 inches
3. If the door in completely open, you must apply the formula for calculate the area of a semicircle:
A=</span>πr²/2
r=28.63 inches
A=π(28.63 inches)²/2
A=1288.11 inches²
The answer is: 1288.11 inches²
