The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2,
timama [110]
N = d - 5

2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3

Let's see if it checks out.
n = 3
d = 8

2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

The birthday candle has the form of a cylinder and cone together, if its has a common radius of 5 mm. The height of cylinder is
alexandr402 [8]

Answer:

1779.33 mm³

Step-by-step explanation:

We are given a candle in a form of a cylinder and a cone

Dimensions;

Common radius is 5 mm

Height of the cylinder is 20 mm

Height of the cone is 8 mm

We are required to determine the amount that it can hold.

To answer the question we are going to determine its volume

Cylinder;

Volume of a cylinder is given by;

V = πr²H

Taking π to be 3.14

Then ;

Volume of cylinder = 3.14 × 5mm² × 20 mm

                                = 1570 mm³

Cone

Volume of a cone is given by;

V = 1/3πr²H

That is;

Volume =1/3 × 3.14 × 5mm² × 8 mm

            = 209.33 mm³

Therefore;

Volume of the solid = 1570 mm³ + 209.33 mm³

                                 = 1779.33 mm³

Thus, the volume of the solid is 1779.33 mm³
