Tamara needs to buy motor oil to fill the 3 empty cylindrical barrels at her oil service center. Each barrel is 7 ft deep and ha
aev [14]
The total volume of the three cylinders is given by:
 V = (3) * (pi) * (r ^ 2) * (d)
 Where,
 r: cylinder radius
 d: cylinder depth
 Substituting values we have:
 V = (3) * (3.14) * (4 ^ 2) * (7)
 V = 1055.04 feet ^ 3
 Answer:
 the volume of oil needed is:
 V = 1055.04 feet ^ 3

A car travels at 60 miles per hour. If d is the distance traveled and t is the time in hours:
erastovalidia [21]

Answer:

Step-by-step explanation:

first we will break the parts of the question down:

d= distance

t= time

function: d=t(60)

the <em>independent </em>variable is t, time, because the (distance) that the car travels <u>depends  </u> on how long the car has been traveling for (time) meaning that the dependent value is distance.

A table we can create with 5 coordinate pairs is:

(time)        (distance)

1 hr            60miles

2 hr           120 miles

3 hr          180 miles

4 hr            240 miles

5 hr           300 miles

(to graph the coordinate pairs, you can graph the points listed in the table. the time value represents the x value since it is the independent variable, and the y value will be the distance values since it is dependent.)
