Answer:
You need the combinations formula:
Combinations = n! / (r! * (n-r)!)
where n = total # of choices (8) and r = # of choices (4)
Combinations = 8 * 7 * 6 * 5 * 4! / (4! * 4 * 3 * 2 * 1)
Combinations = 8 * 7 * 6 * 5 / 4 * 3 * 2 * 1
Combinations = 7 * 2 * 5
Combinations = 70
Step-by-step explanation:
The sum of the interior angles can be represented by:
180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.
56 + 97 + 136 = 289
360 - 289 = 71<span>°

Answer:
The area of the wall that she will paint in two rolls is <u>219.8 inches²</u>.
Step-by-step explanation:
Given:
Jenny uses a roller to paint a wall. The roller has a radius of 1.75 inches and a height of 10 inches.
Now, to find the area of the wall that she will paint in two rolls.
So, we find the lateral surface area of roller.
Radius (r) = 1.75 inches.
Height (h) = 10 inches.
So, to get the lateral surface area we put formula:
Thus, the lateral surface area of the roller = 109.9 inches².
Now, to get the area of wall that she will paint in two rolls we multiply 2 by the lateral surface area of the roller:
Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².
