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:
![A_{L} =2\pi rh](https://tex.z-dn.net/?f=A_%7BL%7D%20%3D2%5Cpi%20rh)
![A_L=2\times 3.14\times 1.75\times 10](https://tex.z-dn.net/?f=A_L%3D2%5Ctimes%203.14%5Ctimes%201.75%5Ctimes%2010)
![A_L=109.9\ inches^2.](https://tex.z-dn.net/?f=A_L%3D109.9%5C%20inches%5E2.)
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:
![109.9\times 2\\\\=219.8\ inches^2.](https://tex.z-dn.net/?f=109.9%5Ctimes%202%5C%5C%5C%5C%3D219.8%5C%20inches%5E2.)
Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².
First, put parenthesis around the first two numbers and the last two numbers.
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis.
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis.
(5g+6) (4g²-3)
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.
Answer:
104.7664068
Step-by-step explanation:
Answer:
Same side: 4, 1.5, 5/3, 0.2
Opposite side: -5, -1/4
Step-by-step explanation:
We know that dilation caused by a positive factor leads to the object being on the same side and dilation caused by a negative factor leads to the object being on the opposite side. Therefore, the dilation caused by positive numbers 4, 1.5, 5/3, 0.2 will lead to object being on the same side. And dilation caused by a negative numbers -5 and -1/4 will lead to object being reflected to the opposite side
