what's the final volume of a gas with an initial volume of 75ml if the pressure decreases from 300ml to 200ml? A. 50.0ml B.112.5

aivan3 [116]

300 ml ... 200 ml
75 ml ... x = ?

If you would like to know what is the final volume of a gas, you can calculate this using the following steps:

300 * x = 200 * 75 /300
x = 200 * 75 / 300
x = 50.0 ml

The correct result would be A. 50.0 ml.

What is the approximate volume of the sphere

NISA [10]

Answer:

523.33 mm³

Step-by-step explanation:

The general formula for the volume of a sphere is:

V = $\frac{4}{3}\pi r^{3}$

The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:

V = $\frac{4}{3}(3.14)(5^{3})$

V ≈ 523.33 mm³

Help ASAP!!!<br> First to answer with a correct answer gets brain...

Llana [10]

Hey there!

First, let's multiply each side of the equation by 3 to get rid of the fraction $\frac{2}{3}$ .

9 + 2x = $\frac{6}{5}$

Next we can multiply each side of the equation by 5 to get rid of the fraction $\frac{6}{5}$ .

45 + 10x = 6

There's your answer!

Hope this helps!

The triangles below are similar. Find x showing the proportion and all work.

zavuch27 [327]

we are given that

two triangles are similar

so, the ratio of their sides must be same

we get

$\frac{2}{6} =\frac{x}{x+2}$

now, we can solve for x

step-1: Cross multiply both sides

$2(x+2) =6x$

step-2: Simplify left side

$2x +4 =6x$

step-3: Subtract both sides by 2x

$2x +4-2x =6x-2x$

$4 =4x$

step-4: Divide both sides by 4

$x=1$

so,

$x=1$ ............Answer
