Answer:

 A)  (3 cm x 4 cm ÷ 2) x 3 cm

Step-by-step explanation:

The volume is the product of the area of the triangular bases and the distance between them.

Each right triangular base has a width of 3 cm and a height of 4 cm. Its area will be given by ...

 A = (1/2)bh

 A = (1/2)(3 cm)(4 cm) = (3 cm × 4 cm) ÷ 2

__

The distance between the triangular bases is marked at the left side of the diagram as 3 cm. So, the volume is ...

 V = Bh

 V = (3 cm × 4 cm ÷ 2) × 3 cm . . . . . matches choice A

There aren't any more steps. The answer starts by saying how the volume is computed. Then it shows how to find the numbers that go into that computation. Finally, it puts all that together in the form that is required to match an answer choice.

It might also be useful for you to draw the net to scale on a piece of paper, cut it out, and fold it along the lines to actually make a triangular prism. A little hands-on is always helpful in math. It only takes 5 or 10 minutes and can give you great insight into both prisms and nets.

A wall shaped like a trapezoid needs to be painted. the height of the wall is 16 feet and the bases are 20 feet and 24 feet. if
AURORKA [14]
Area of Trapezoid = h(b1+b2/2)
 b1 and b2 are the lengths of each base and h is the height.

Area = 16(20+24/2)=352 Square Feet 

352/20=17.6 Cans of paint.

Hope this helps and is correct, I haven't done this kind of math in a while.

What is the solution to<br> 6(2 - x)&lt;-4x + 2?
cupoosta [38]

Answer:

Solving 6(2 - x) we get \mathbf{x>5}

Step-by-step explanation:

We need to find solution of 6(2 - x)

Solving the inequality:

6(2 - x)

Multiply 6 with terms inside the bracket

12-6x

Subtracting 12 on both sides

12-6x-12

Adding 4x on both sides

-6x+4x

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}

So, after solving 6(2 - x) we get \mathbf{x>5}
