Two spheres m and n have volumes of 250 cm and 750 cubic cm respectively. What is the ratio of their radius

Mathematics

Let's look at the formula for the volume of a sphere:

                 Volume = (4/3) (pi) (radius)³ .

If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by  (anything)³ .

Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by  ∛(something).

In this question, the ratio of the volumes is  3 .
So the ratio of the radii (radiuses) is  ∛3 = about  1.442  (rounded)

How to do this problem 15: x +17 =32
Juliette [100K]
SO x plus 17 are equal to 32. That means you know that 17 plus some unknown number can equal 32. To find this number, simply subtract 17 on both sides. This will get you x=15. Hope it helps.

Which best describes the equation that the graph represents?
andreev551 [17]

Answer:

y= \frac{9}{5}x

Step-by-step explanation:

Given the two points:

  • Origin (x1, y1) = (0, 0)
  • The point (x2, y2) = (5, 9)

Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).

=>Time, x the independent variable,and distance is the dependent variable.

We have the standard form of a linear equation is:

y= mx + b where a is the slope

We know that, the slope of the function is:

m = \frac{y2-y1}{x2-x1}

In this situatuon, m = \frac{9-0}{5-0} = \frac{9}{5}

=> y= \frac{9}{5}x + b(1)

The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:

0 = \frac{9}{5}*0 + b

<=> b = 0

So our equation that the graph represents is: y= \frac{9}{5}x
