Answer:

<h2>QS = 42</h2><h2></h2>

Step-by-step explanation:

R is midpoint

|<---------------- QS -------------------->|

Q---------------------R--------------------S

       8x - 51                 3x - 6

find: QS

QR = RS

8x - 51 = 3x - 6

8x - 3x = 51 - 6

5x = 45

x = 45/5

x = 9

QS = QR + RS

QS = (8x - 51) + (3x - 6)

plugin the value of x=9 into the equation above:

QS = (8(9) - 51) + (3(9) - 6)

QS = 72 - 51 + 27 - 6

QS = 42

Answer:

5,720,000 Sq Feet.

Step-by-step explanation:

They are asking the Area of a Trapezoid

Equation =( base + base / 2) x height

Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.

So if you multiply them (200 x 260) You will get 52000.

Now we divide that by 2. (52000 / 2 = 26000)

Now it says the straight line is 220. I think this refers to the height.

Now we multiply 26000 x 220. Which is 5720000.

Its a pretty big number, but that is the answer! :)

Hope this helps!

PLEASE SOMEONE HELP AND SHOW UR WORK..

Answer: The answer is 2,713 in³

The volume (V) of the prop is the sum of the volume of cone (V1) and half of the volume of the sphere (V2): V = V1 + 1/2 * V2

Volume of the cone is:

V1 = π r² h / 3

According to the image,

h = 14 in

r = 9 in

and

π = 3.14

V1 = 3.14 * 9² * 14 / 3 =  1,186.92 in³

The volume of the sphere is:

V2 = π r³ * 4/3

According to the image,

r = 9 in

and

π = 3.14

V2 = 3.14 * 9³ * 4/3 = 3,052.08 in³

The volume of the prop is:

V = V1 + 1/2 * V2

V = 1,186.92 in³ + 1/2 * 3,052.08 in³

V = 1,186.92 in³  + 1,526.04 in³ 

V = 2,712.96 in³ ≈ 2,713 in³
