Find the volume of this cube in cm³

Degger [83]

Answer:

It is c: 15.625 cm³

Step-by-step explanation:

Formular for cube volumes:

${ \tt{volume = (side \times side \times side)}} \\ { \tt{v = (s_{1} \times s_{2} \times s_{3}) }}$

since sides of a cube are identical:

${ \sf{s_{1} = {s_{2} = {s_{3}}}}}$

Therefore:

${ \sf{volume = (250 \times 250 \times 250) \: mm {}^{3} }} \\ { \sf{v =15,625,000 \: {mm}^{3} }}$

but 1 mm³ = 0.000001 cm³

${ \sf{v = (15,625,000 \times \{1 \times {10}^{ - 6} \} ) \: cm}} \\ { \sf{v = 15.625 \: {cm}^{3} }}$

9 11/12- 2 8/11 is a problem that i need help on

Vitek1552 [10]

Hey there!!

Okay here are the steps you can follow!

9 11/12 ----> improper fraction ----> 119/12
2 8/11 ----> improper fraction ----> 30/11

119/12 - 30/11
(119/12 - 30/11) * 132
11(119) - 12(30)
1309 - 360
949

Determine the equation of the line that is parallel to the given line, through the given point.

Verdich [7]

Answer:

$y=-\frac{3}{2}x+1$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope (m)

$3x+2y = 10$

First, we must organize this given equation in slope-intercept form. This will help us identify its slope.

$3x+2y = 10$

Subtract 3x from both sides

$2y = -3x+10$

Divide both sides by 2

$y = -\frac{3}{2} x+5$

Now, we can identify clearly that $-\frac{3}{2}$ is in the place of m in $y=mx+b$ , making it the slope. Because parallel lines have the same slope, this makes the slope of the line we're currently solving for $-\frac{3}{2}$ as well. Plug this number into $y=mx+b$ :
