2x ≤ 9 +5
2x ≤ 14
or x ≤ 7
C) 5x+8≤53
5x ≤ 53 -8
5x ≤ 45
or x ≤ 9
D) 3x−5≥16
3x ≥ 16 + 5
3x ≥ 21
or x ≥ 7
Have a good day!
Answer:
C($)= (x²/2 +11x)5.75
Step-by-step explanation:
Let's assume the height= x
The base= x+22
Area= 1/2(base*height).
Area= 1/2((x+22)(x))
Area= x²/2 +11x
Cost per ft= $5.75
Cost for painting the triangular mural C
C($)= (x²/2 +11x)5.75
48 + (2*13) / 110
PE(MD)(AS)
2 * 13 = 26
48 + 26 / 110
26 / 110 = 0.236..
Rounded = 0.24
48 + 0.24 = 48.24….

Answer:
A. ![V = (pi)(3.25)^2(12)](https://tex.z-dn.net/?f=V%20%3D%20%28pi%29%283.25%29%5E2%2812%29)
Step-by-step explanation:
The formula for the volume of a cylinder is the formula for the area of the circle, times the height of the cylinder. The formula for the volume of a circle is,
![A = (pi)(r)^2](https://tex.z-dn.net/?f=A%20%3D%20%28pi%29%28r%29%5E2)
Multiply that by the height to find the formula for the volume of a cylinder,
![V=(pi)(r)^2(h)](https://tex.z-dn.net/?f=V%3D%28pi%29%28r%29%5E2%28h%29)
Where (pi) represents the value (3.1415), (r) represents the radius, and (h) represents the height of the cylinder. Now substitute in the given values, remember, this problem gives the diameter of the cylinder, divide that value by two to find the radius.
![V=(pi)(\frac{6.5}{2})^2(12)\\\\V = (pi)(3.25)^2(12)](https://tex.z-dn.net/?f=V%3D%28pi%29%28%5Cfrac%7B6.5%7D%7B2%7D%29%5E2%2812%29%5C%5C%5C%5CV%20%3D%20%28pi%29%283.25%29%5E2%2812%29)
Answer:
You will pay $332.50 for a item with original price of $475 when discounted 30%
meaning the discount is $142.50
Step-by-step explanation:
if you buy an item at $475 with 30% discount, you will pay 475 - 142.5 = 332.5 dollars.
please give brainliest and thanks if possible
