Mathematics

Answer:

the perimeter is 11cm and the area is 7cm^2

Step-by-step explanation:

NP =PS, meaning they have the same length. so the perimeter is 3.5 + 4 + another 3.5.

For the area imagine you cut the triangle in half. from P to the middle of NS. Put the 2 triangle halves together to form a rectangle. (PS is now touching NP). This would be a 2x 3.5 rectangle. 2x 3.5 is 7, meaning both this imagined rectangle and the triangle have an area of 7cm^2.

2. 3x + 2y = 22<br> 5x – 2y = 42
hammer [34]

Step-by-step explanation:

3x+2y=22

5x-2y=42

by adding both equation

8x. =64

x=64/8=8

substituting x in the 1st equation

we get,

3*8+2y=22

24+2y=22

2y=22-24

y=-2/2=-1

therefore,

x=8

y=-1

The chairman of the community bazaar is assigning people to chair committees. How many different ways can the 6 people be assign
iren [92.7K]

The 6 people be assigned in 720 different ways to chair the subcommittees.

<u>Step-by-step explanation:</u>

Given that,

  • There are 6 people to be assigned to the chair committees.
  • So, you need to find that in how many ways they can be assigned their seats.

This can be calculated by Permutation.

The number of arrangements in which the order of the objects matters is calculated as permutation.

The permutation is given as ⇒ P = n!

Here we can 6 people to be assigned. Therefore n = 6.

⇒ Number of ways can be arranged = 6!

⇒ 6×5×4×3×2×1

⇒ 720

∴ The 6 people be assigned in 720 different ways to chair the subcommittees.

Which angles are pairs of alternate exterior angles? Check all that apply.
Gnom [1K]
Answers: 
1. Angle 5 and angle 11
5. Angle 4 and angle 6

================================================

Explanations:

Let's go through the list of possible choices and check each one.

For each of these, I'll refer to the attached image. 

-------------------------

1. Angle 5 and angle 11

Note how I labeled the lines A through D (as well as color-coded them). Imagine if line A and line B were made to be parallel lines. Line D is the transversal cut that helps generate angle 5 and angle 11. We'll be focusing on this tranversal. Ignore line C entirely for now.

We can see that angle 5 and angle 11 are on the outside of the "parallel" train tracks that A and B form. That makes them exterior angles. The two angles are on alternate sides of the transversal cut line D. All together, they are alternate exterior angles. 

This is one of the answers

-------------------------

2. Angle 7 and angle 12

Again focus on only line A, B, and D. Ignore line C. Angle 12 is exterior but angle 7 is an interior angle. It is between the two "parallel" train tracks line A and line B. 

Cross this off the list.

-------------------------

3. Angle 11 and angle 16

This time we'll imagine that line C and line D can be rearranged to be parallel. Line B is the transversal cut we want. Ignore line A entirely.

Angle 16 and angle 11 are exterior angles with regards to the lines mentioned above; however, they do not alternate on opposite sides of line B. These two angles are same side exterior angles. 

Cross this off the list.

-------------------------

4. Angle 2 and angle 14

These two angles are corresponding angles. Imagine line A and B are laid parallel with line C as the transversal cut. 

Angle 2 and angle 14 are on the same side of the transversal cut. The two angles are both above their adjacent line (A and B)

Cross this off the list.

-------------------------

5. Angle 4 and angle 6

Imagine that line C and line D can be rearranged to be parallel. Line A is the transversal cut we want. Ignore line B entirely.

Based on that set up, we can see that angle 4 and angle 6 are indeed alternate exterior angles.

This is one of the answers

-------------------------

6. Angle 8 and angle 10

These are alternate interior angles. It might help to erase line C. It might also help to arrange line A to be parallel to line B. 

Cross this off the list.
