Answer:

option c is correct

180 cars can they wash in 15 hours

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity 1 such as 4 miles per hour or 5 meter per second.

As per the statement:

Some students washed 24 cars in 2 hours

Then by definition of unit rate.

\text{unit rate per hour}=\frac{24}{2} = 12

We have to find how many cars can they wash in 15 hours

⇒\text{Number of cars washed in 15 hours} = \text{Unit rate per hour} \cdot 15

Substitute the given values we have;

\text{Number of cars washed in 15 hours} = 12 \cdot 15

Simplify:

\text{Number of cars washed in 15 hours} = 180

Therefore, 180 cars can they wash in 15 hours

Find the surface area of the tin game case
butalik [34]
To find the surface area you will need to find the area of all 5 surfaces (faces) on the prism.  On a triangular prism there are 2 triangular faces and 3 rectangular faces.  All 3 rectangular faces are the same and the 2 triangular faces are also the same.

To find the area of the triangular faces, you will use the formula for finding the area of a triangle:

A = 1/2bh
     1/2 x 10 x 8.7
A = 43.5 in^2 

To find the area of the rectangular faces, you will use the formula for finding the area of a rectangle:

A = bh
    10 x 3
A = 30 in ^2

30 + 30 + 30 + 43.5 + 43.5 = 177

The minimum amount of wrapping paper needed for the gift is 177 square inches.
