Answer:

The answer is 5

Step-by-step explanation:

We need to find out how many students turned in the project on Wednesday. In order to do this, this is what we need to do.

1. First we need to subtract 12 from 30 since 12 is how many students turned in the project on Monday.

2. 30 - 12 = 18

So now we have 18.

3. Next we need to subtract 13 from 18 since we know that 13 is how many students turned in the project on Tuesday.

4. 18 - 13 = 5

At the end we end up with 5.

So 5 students turned in the project on Wednesday.

What is the surface area of the triangular prism shown? A triangular prism. The triangle faces have base 14 meters and height 24
Alekssandra [29.7K]

Answer:

1064 m²

Step-by-step explanation:

The surface area of the prism can be gotten by saying

14 * 14 + 14 * 14 + 14 * 24 =

196 + 196 + 336 =

728 m²

Again, after dealing with the rectangle, we then face the triangle.

Area of triangle is

1/2 * 14 * 24

There are 2 triangles so this makes it

2 * 1/2 * 14 * 24 =

336

The surface area is finally

336 + 728 = 1064 m²

Surface area of the triangular prism has been calculated to be 1064 m²
