Answer:

x= 8

Step-by-step explanation:

Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.

3x + 12 + 7x + 88 = 180

Add like terms

10x + 100 = 180

-100. -100

10x = 80

/10. /10

x = 8

A cylindrical basin is 2 feet tall and has a diameter of 5 feet, as shown. If the basin is completely filled with water, how muc
jarptica [38.1K]

Answer:

39.3 ft^3

Step-by-step explanation:

The cylindrical basin has a height of 2 ft and a diameter of 5 ft.

To find the amount of water that will completely fill up the basin, we simply need to find the volume of the basin.

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius of the basin (half the diameter) = 2.5 ft

h = height of the basin

Hence, the volume is:

V = \pi * 2.5^2 * 2

V = 39.27 ft^3 ≅ 39.3 ft^3

The cylindrical basin can hold up to 39.3 ft^3 of water.

Solve this equation: 4y + 228 = 352. <br> A. y = 31<br> B. y = – 31<br> C. y = 3<br> D. y = 145
V125BC [204]
To let the variable alone you can follow these steps: 1) subtract 228 from both sides 2) divide both sides by 4. This is the solution: 1) 4y + 228 - 228 = 352 - 228 => 2) 4y = 124 => 3) (4y)/4 = 124/4 => 4) y = 31. Then, <span>the answer is the option A. y = 31. </span>
