Answer:

A.

Step-by-step explanation:

The volume of rectangular prism is l x w x h

So, 12 x 6 x 8 =576

Volume of triangular prism is l x w /2 x h

So, 6x8=48/2= 24

24x12=288

576/288=2

This shows that the rectangular prism is 2 times larger than the triangular prism.

Therefore, the answer is A.

The answer to the question is A.

How many cubes that measure 2 inches by 2 inches by 2 inches would fit inside a cube that measures 10 inches by 10 inches by 10 inches? Justify.

Answers

25, because a cube that is 10x10 would have an area of 100. and the cubes that are 2x2 would have an area of 4. so you take 100 and divide it by 4. answer is 25.

The number of the small cube that fits inside the larger cube is 125.

Given to us,

Side of small cube, s = 2 inches,

Side of larger Cube. S = 10 inches,

We know that volume of a cube is given by , where "a" is the side of the cube.

Volume of the small cube = s³ = 2³ = 8 in.³

Volume of the Larger cube = S³ = 10³ = 1000 in.³

The number of the small cube that fits inside the larger cube

                                           [tex]\bold{=\dfrac{Volume\ of\ the\ Larger\ cube}{Volume\ of\ the\ small\ cube} }[/tex]

                                           [tex]\bold{=\dfrac{1000}{8} = 125 }[/tex]

Hence, the number of the small cube that fits inside the larger cube is 125.

2 inches
4 inches
8 inches
9 inches

Answers

Answer:

R = sqrt 3 * (V /( pi * h))

V = 62.8

pi = 3.14

h = 15

now we sub

R = sqrt 3 * (62.8 / (3.14 * 15)

R = sqrt 3 * (62.6 / 47.1)

R = sqrt 3 * 1.33

R = sqrt 3.99

R = 1.9 rounds to 2 inches <===

Answer:

Your answer is correct here's an example.

Step-by-step explanation:Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood

The correct answer is C. Viruses using living cells to make new viruses.

Because viruses are not living (sunce they cannot reproduce/make more of their species on their own) they depend on a living finction cell. They give their DNA and manipulate the living cell (which would now become a host cell for the breeding ground for the virus) and create more copies of the virus, which would also then go and find other living cells to mass reproduce the virus which would kill a lot of the living cells therefore harming the organism that is containing the virus
