Ray made a toolbox with the dimensions shown to store garden tools. What is the volume of the toolbox?

Answers

Answer:61

Step-by-step explanation:

As per the dimensions shown to store garden tools, the volume of Ray's toolbox is 7200 cubic units.

In order to determine the volume of Ray's toolbox, we need to use the formula for calculating the volume of a rectangular prism, which is

V = length × width × height.

Given the dimensions provided, the height of the toolbox is 12 units, the width is also 12 units, and the length is 50 units.

Now, let's substitute these values into the formula:

V = 12 units (height) × 12 units (width) × 50 units (length)

V = 12 × 12 × 50

V = 7200 cubic units

What is the ratio of 50 cents to $1.20 (in simplest form)?

Answers

Answer:

5:12

Step-by-step explanation:

$1.20 = (1x100 + 20) cents = 120 cents

You get a ratio of 50:120.

Since both are divisible by 10, divide both sides by 10.

You get 5:12.

Since 5 and 12 share no common factors other than 1, this is the simplest form.

Answers

Answer:

1200

Step-by-step explanation:

Step 1 convert pounds to ounces

1 pound = 16 ounces

So to convert pounds to ounces we multiply by 16

1500 * 16 = 24000

So there are 24000 ounces in 1500 pounds

Step 2 Find how many 20 ounce containers he can fill.

To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20

So answer = 24000/20

24000 / 20 = 1200

Therefore he can fill 1200 20 - ounce containers

A car travels 60 miles in 50 minutes. Calculate the average speed of the car in mph.

Answers

Average speed: 72 mph
Explanation:
To get the car's average speed, all you really need to know is
the total distance travelled by the car
the total time it needed to cover that distance
In your case, you know that the car travelled for a total of 60 miles and that it needed 50 minutes to do so.
Since you need to express the average speed in miles per hour, not miles per minute, you're going to have to use a simple conversion factor to get you from minutes to hours.
First, calculate the average speed in miles per minute
v

At the teachers gentle insistence, Casandra reluctantly joined the other children on the playground. Tears rolled down her cheeks when the teacher boosted Casandra onto a swing seat and began to push her. The teacher stopped the swing and helped Casandra off. She held her closely for a few minutes and then asked why she was crying. Casandra initially denied that anything was wrong. However, when the teacher persisted, said she "had fallen the night before and hurt her bottom."The teacher took Casandra inside and asked to see where she had been hurt. When Casandra pulled down her shorts, the teacher noted what appeared to be a large burn with blisters approximately 2 inches in length by 1 inch in width on her left buttock. Several small bruises were also evident along one side of the burn. Again, the teacher quietly asked Casandra how she had been hurt, and once again she replied that she "had fallen."What actions should Casandras teacher take?
