V1 = π* ( r1)^2 * 75;
V2 = π* ( r2)^2 * 25;

V1/V2 = (r1/r2)^2 * 3.

The ratio of the lengths is 75 : 25 or 3 : 1 

The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)

The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)

Hopefully this explains it

What is the value of z?
babymother [125]

Answer:

Step-by-step explanation:

<u>Item 1:</u>

Discount = Original price - discount price

             = 22.50 - 13.50

             = $ 9

Discount percentage = \frac{9}{22.50}*100\\\\

                                   = 40%

Discount percentage = 40%

Tax = 14.31 - 13.50 = $0.81

Tax% = \frac{0.81}{13.50}*100\\\\  = 6%

Tax percentage = 6%

<u>Item 2:</u>

Tax = 6% of 16.20

      = 0.06 * 16.20

      = 0.972

Tax = $ 0.97

Total price (including tax )= 16.20 + 0.97 = $ 17.17

         x = $ 17.17

<u>Item 3:</u>

Discount  = 40% of 32.50

                        = 0.4 * 32.50

                        = $ 13

y =  32.50 -13

y = $ 19. 50

Tax = 6% of 19.50

       = 0.06 * 19.50

       = 1.17

z = 1.17 + 19.50

Z  =$ 20.67

The length of each square on the grid represents 1 cm. The scale
tatyana61 [14]

Answer:

Step-by-step explanation:

Length of the rectangle given in the the figure attached = 2 cm

Width of the rectangle = 5 cm

Scale used, 24 in to 1 cm

Therefore, length of actual rectangle = 2×24 = 48 in

width of the actual rectangle = 5×24 = 120 in

Now we have to draw a drawing by using the scale,

16 inches to 1 cm

Or 1 inch = \frac{1}{16} cm

Therefore, length of the rectangle drawing = 48\times \frac{1}{16}

                                                                        = 3 cm

Similarly, width of the rectangle drawing = 120\times \frac{1}{16}

                                                                    = 7.5 cm

a rectangle has an area of 7/8 square units if the width is 7/16 unit what is the length of the rectangle in units?
djyliett [7]

Answer:

Length=2 units

Step-by-step explanation:

Given :

Area of the rectangle =\frac{7}{8}  square units

Width of the rectangle=\frac{7}{16} units

Area of the rectangle= Length* Width

                         \frac{7}{8} =Length*\frac{7}{16}

Multiplying  \frac{16}{7} both the sides

                      \frac{7}{8} *\frac{16}{7} =Length

                     Length=\frac{16}{8}

                   Length=2 units

The length of the rectangle is 2 units
