Answer:

3k+28 miles

Step-by-step explanation:

We are given that

Kim drove distance to see her family=k miles

We have to find the expression which represents the number of miles Tran drove.

According to question

3 times of k=3k

Now, adding 28 to 3k

Therefore, the expression is given by

3k+28

Hence, the expression which represents the number of miles Tran drove

3k+28 miles

Lin runs 5 laps around a track in 6 minutes.
Paladinen [302]

Answer:

25.2

Step-by-step explanation:

6/5 is 1.2, so it takes 1.2 minutes to run one lap.

This means 21 x 1.2 = the minutes it takes to run 21 laps around the track.

Therefore it takes 25.2 minutes to run around the track 21 times.

Answer:

37.68 units³

Step-by-step explanation:

To calculate the volume of a cone, the formula is:

V = π x r² x ( h / 3 )

Simply input the corresponding numbers into the equation:

V = π x ( 2 )² x ( 9 / 3 )

V = π x 4 x ( 3 )

V = π x 12

V = 3.14 x 12

V = 37.68 units³

If we use 3.14 for pi, the answer comes out to 37.68 units³

Answer:

The rental company also provides 4 different sizes of moving boxes for purchase.The volume of each box doubles in size from the volume of the next smallest box

Step-by-step explanation:

Linear functions those relation which produces a straight line graph while non - linear functios produces curves or other shapes asides a straight line. Non linear functios could be quadratic, Exponential or so on in nature.

Equation of a linear equation include :

y = a + bx OR

y = bx

First expression :

y = $50 + x ;

slope, b = 1 ; intercept, a = 50

Third expression :

y(x) = 105x

Second expression:

V(x) = V0 * e^2x

Second expression is exponential while the first and third is linear.
