Answer:

Step-by-step explanation:

The formula fo an area of a triangle:

$A=\dfrac{bh}{2}$

b - base

h - height

We have

x - base

6x - height

Substitute:

$A=\dfrac{(x)(6x)}{2}=\dfrac{6x^2}{2}=3x^2$

Two cells are viewed and measured under a microscope. The approximate diameter

nikklg [1K]

Answer:

option D. 4.7 x 10-4 m

Step-by-step explanation:

<u><em>The correct question is</em></u>

• cell P: 5.0 x 10-4 meters

• cell Q: 3.0 x 10-5 meters

we have

The diameter of cell P is $5*10^{-4}\ m$

The diameter of cell Q is $3*10^{-5}\ m$

Rewrite the diameter of cell P as

$5*10^{-4}\ m=5*10^{-4}(\frac{10}{10})=50*10^{-5}\ m$

Find the difference

$50*10^{-5}\ m-3*10^{-5}\ m=47*10^{-5}\ m$

Rewrite the difference as

$47*10^{-5}\ m=47*10^{-5}}(\frac{10}{10})=4.7*10^{-4}\ m$

Cube-shaped blocks are packed into a cube-shaped storage container. The edge length of the storage container is 212 feet. The

igor_vitrenko [27]

Answer:

The volume of cube-shaped block is 0.125 cubic feet.

Step-by-step explanation:

We are given the following in the question:

Edge length of storage container =

$2\dfrac{1}{2}\text{ feet}$

Edge length of block =

$\dfrac{1}{5}\times \text{Edge length of container}$

Putting value we get,

Edge length of block =

$\dfrac{1}{5}\times 2\dfrac{1}{2}\\\\=\dfrac{1}{5}\times \dfrac{5}{2}\\\\=\dfrac{1}{2}\text{ feet}$

Volume of cube-shaped block = Volume of cube

$V = \text{(Edge)}^3\\\\V =(\dfrac{1}{2})^3\\\\V = \dfrac{1}{8}\text{ cubic feet}\\\\V = 0.125\text{ cubic feet}$

Thus, the volume of cube-shaped block is 0.125 cubic feet.

Colt1911 [192]

Do a proportion.
5/32= x/800
Cross multiply and divide
800 x 5= 4,000
4,000 divided by 32= 125
So answer is 125 students
