Answer 1

Answer: 1) 3/5=9/x (cross multiply)
3x=5(9)
3x=45
x=15

2) 2/4=x/12   (cross multiply)
2(12)=4x
   24=4x
   6=x

3) 10/x=5/9   (cross multiply)
10(9)=5x
90=5x
18=x

4) 5/6=x/18
5(18)=6x
90=6x
x=15

How many diagonals does a triangular prism have?

Answers

The number of diagonals that the triangular prism will have is 6.

What is a triangular prism?

Suppose you've got a triangle. Now, stretch it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.

Usually, when we talk about a triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.

Since a triangularprism is made up of 2 triangles and 3 rectangles. Also, a triangle has no diagonals while a rectangle has 2 diagonals. Therefore, the number of diagonals, the triangular prism will have is,

Number of diagonal

= Number of diagonals on triangles + Number of diagonals on rectangles

= (2×0) + (3×2)

= 6

Hence, the number of diagonals that the triangular prism will have is 6.

The formula for the area of a rectangle is:

A=l*w

Since we know both the length, 15, and the area, 150, we can solve for the width.

150=15*w
Divide both sides by 15
10=w

The width is 10ft

Answer= The Dimensions of the rug are 10ft by 15ft

2)
The formula for the area of a rectangle is:
A=l*w

To solve for this problem, we need to subtract the area of the rug, from the area of the room.

A(room)-A(rug)=A(remaining)

We still don't know the area of the entire room, so lets solve for that

A(room)=l*w
A(room)=25*20
A(room)=500sq ft

Now we can search for the remaining area...

A(room)-A(rug)=A(remaining)
500-150=
350 sqft

Answer=350 sqft

the second angle in a triangle is five times as large as the first. The third angle is 2/3 as large as the first. What are the angle measures?

Answers

Hello,
let x the first angle

5x the second
2/3 x the third

x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18

27+135+18=180
