Answer:

The correct option is C. The height of the cylinder is 9 cm.

Step-by-step explanation:

The radius of cone is 12 cm and the height of cone is 12 cm.

The volume of cone is

V=\frac{1}{3}\pi r^2h

V_1=\frac{1}{3}\pi (12)^2(12)

V_1=576\pi

The radius of cylinder is 8 cm. The volume of cylinder is

V=\pi r^2h

V_2=\pi (8)^2h

V_2=64\pi h

It is given that the volume of cone and cylinder is same.

V_1=V_2

576\pi=64\pi h

\frac{576\pi}{64\pi}=h

9=h

Therefore the height of the cylinder is 9 cm and option C is correct.

The answer:

according to the image the coordinates of pre image are:

A(-7, 2), B(-5, 3) C(-2, 2) and D(-5, 1)

<span>Kite ABCD is reflected over the line y = x, the main rule to find the coordinates of the images is  (y, x)

for example if A(-7, 2) the image  A' is A'(2, -7)

the answer is </span><span>(x,y)→(y,x); A' is at (2, −7)</span>

Rosa and Albert receive the same amount of allowance each week . The table shows what part of their allowance they each spent on
Anettt [7]
1/2 x > 0.4x

where Robert's spending is greater than Rosa's spending.

Allowance of Rosa = Allowance of Robert

let x = allowance

Rosa : video games = 0.4(x) ; pizza = 2/5 (x)
Robert : video games = 1/2 (x) ; pizza = 0.25 (x)

let us assume that their allowance is 100 each week. so, x = 100

Rosa : video games = 0.40(100) = 40
           pizza 2/5 (100) = 200/5 = 40
total spending: 40 + 40 = 80

Robert : video games = 1/2 (100) = 50
             pizza 0.25 (100) = 25
total spending: 50 + 25 = 75

Spending on video games
Rosa = 40
Robert = 50

Robert spent more of his allowance on video games than Rosa.

1/2 x > 0.4x
