Answer:

The answer would be a) 4-2g

Step-by-step explanation:

Multiplying by one half is like dividing by 2!

8/2 = 4

and

4/2 = 2

It can't be b because you can't add 4g+2

It can't be c because you can't completely remove the 8/4

It can't be d because you didn't actually distribute

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inc

Bond [772]

The relationship is that two times the volume of cylinder is volume of cone

Solution:

Given that, cylinder and a cone have the same diameter: 8 inches

Diameter = 8 inches

Radius is diameter divided by 2

$radius = \frac{diameter}{2}\\\\radius = \frac{8}{2} = 4$

Radius = 4 inches

Let us find the volume of cylinder and cone

Volume of cylinder:

$volume = \pi r^2 h$

Radius = 4 inches

The height of the cylinder is 3 inches

height = 3 inches

Substituting the values, we get

$volume = 3.14 \times 4^2 \times 3\\\\volume = 3.14 \times 16 \times 3\\\\volume = 150.72$

Thus volume of cylinder is 150.72 cubic inches

Volume of cone:

$volume = \frac{\pi r^2h}{3}$

Radius = 4 inches

The height of the cone is 18 inches

height = 18 inches

Substituting the values, we get

$volume = \frac{3.14 \times 4^2 \times 18}{3}\\\\volume = 3.14 \times 16 \times 6\\\\volume = 301.44$

Thus volume of cone is 301.44 cubic inches

What is the relationship between the volume of this cylinder and this cone?

Volume of cylinder is 150.72 cubic inches

Volume of cone is 301.44 cubic inches

On observing the volume of cylinder and cone, we find that two times the volume of cylinder is volume of cone

$2 \times \text{Volume of cylinder} = \text{Volume of cone}$

$2 \times 150.72 = 301.44\\\\301.44 = 301.44$

Thus the relationship between the volume of this cylinder and this cone is that two times the volume of cylinder is volume of cone

PLEASE HELP!!! TIMED QUESTION!!! NOT A TEST NOR QUIZ!!!!

Answer:

LCD=280

Step-by-step explanation:

Equivalent Fractions with the LCD

1/8 = 35/280

2/7 = 80/280

4/5 = 224/280

Solution:

Rewriting input as fractions if necessary: 1/8, 2/7, 4/5

For the denominators (8, 7, 5) the least common multiple (LCM) is 280.

LCM(8, 7, 5)

Therefore, the least common denominator (LCD) is 280.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 35/35 = 35/280

2/7 = 2/7 × 40/40 = 80/280

4/5 = 4/5 × 56/56 = 224/280
