Use the pattern to extend the table. Then answer the question below. Include two decimals for each answer even if they are 0 Cars Washed Money Earned (Hint: this is how much you would earn for 1 car) How much is earned per car? $ How much will be earned for 20 cars?

Answers

We know that 3 cars yielded $13.50

$13.50 / 3 = $4.50 / 1 car

$4.50 * 12 cars = $54.00

$4.50 * 15 cars = $67.50

$4.50 * 20 = $90.00

A printer can print 40 pages in 1.6 minutesa- Write an proportion to find the number of pages that the printer in 5 minutes, show your work
b- lana wants to use the printer to print 150 pages hows long will the take her

Answers

Given:
40 pages in 1.6 minutes

40 / 1.6 = 25 pages per minute

25 x 5 minutes = 125 pages

40 / 1.6 = x / 5
40*5 = 1.6x
200 = 1.6x
200/1.6 = x
125 = x pages

25 : 1 = 150 : x
25x = 150
x = 150/25
x = 6 minutes

Volume is measured in cubic units true false

Answers

Answer:

The statement is true.

Step-by-step explanation:

Volume is the measurement of the space occupied by any object. Thus, mathematically, we can represent volume as the product of area and height.

Thus, we have

Volume = Area × height

Now, we know that area is measured in square units and height is in units.

Thus, we have

Volume = Square units ×units

Volume = cubic units.

Therefore, we can conclude that volume is measured in cubic units.

Thus, the statement is true.

Volume is measured in cubic units is true statement.

Volume is a measurement of the amount of space occupied by a three-dimensional object.

It is expressed in cubicunits because it involves measuring the extent of the object in three dimensions: length, width, and height.

When these dimensions are multiplied together, the result is a quantity that represents the volume of the object.

Hence, volume is measured in cubic units is true statement.
