Determine the constant of variation for the direct variation given.
ohaa [14]

Answer:

B. 5

Step-by-step explanation:

We have been given that R varies directly with S. When S is 16, R is 80. We are asked to find constant of variation.

We know that two directly proportional quantities are in form y=kx, where,

k = Constant of variation.

Upon substituting our given values, we will get:

R=k*S

80=k*16

\frac{80}{16}=\frac{k*16}{16}

5=k

Therefore, the constant of variation is 5 and option B is the correct choice.

The expression below is a sum of cubes.<br> 216x3 +64<br> true or false?
zepelin [54]

Since 216 is the cube of 6, 64 is the cube of 4 and x^3 is the cube of x, we have

216x^3 + 64= (6x)^3+4^3

so the expression is the sum of the cubes of 6x and 4

I need some help on this thanks!!!<br><br><br><br><br><br><br><br> -

Answer:

The 4th option, 10g + 24 = t

Step-by-step explanation:

It costs 24 dollars per month no matter what.

$10 * the amount of GB you want

Add those two values to get the total cost per month.

In this case you want 5 GB, so substitute the g in the equation for 5. You will get:

10 * 5 +24 = t

50 + 24 = t

74 = t

So it costs 74 dollars per month to get 5 GB.
