Answer:

729

Step-by-step explanation:

Alright so our 2 big things here are order of operations and laws of exponets.

1st we need to find (-3)^4 and (-3)^2.

-3 raised to 4 is 81, and -3 raised to the 2nd power is 9.

So now our simplified equation is (81/9)^3.

Now we use the power of a quotient rule from the laws of exponets (look this name up and you'll easily find it).

So now our equation is (81^3)/(9^3). This equals 729.

Hope this helps!

The answer to the question is 729!

Fatimah's grade is 52/50. You can write this as 1 + 2/50 = 1 + 1/25 =

1 and 1/25.

52/50
There is one 50 in 52, so the first part of our answer will be a 1.

Which angle is supplementary to ∠MPN?

five angles all with common vertex of P, with angle NPI measuring 55.6 degrees, angle IPK measuring 44.2 degrees, angle KPL measuring 80.2 degrees, angle LPM measuring 55.6 degrees, and angle MPN measuring 124.4 degrees

∠NPL
∠LPM
∠IPK
∠KPL

Answers

The ∠LPM is supplementary to ∠MPN.

What is supplementary angles?

If two angles in geometry sum up to 180 degrees, they are considered to be supplementary angles. For instance, A and B are referred to as supplementary angles if ∠A + ∠B = 180°. When combined, supplementary angles always make a straight angle (180 degrees).

Given:
Five angles all with common vertex of P, with angle NPI measuring 55.6 degrees, angle IPK measuring 44.2 degrees, angle KPL measuring 80.2 degrees, angle LPM measuring 55.6 degrees, and angle MPN measuring 124.4 degrees

We have to find the angle which is supplementary to the ∠MPN.

Let, x be the angle supplementary to the ∠MPN.

So,

x + ∠MPN = 180

x = 124.4 = 180

x = 180 - 124.4

x = 55.6

Therefore, ∠LPM is supplementary to ∠MPN.

A recent conference had 650 people in attendance. In one exhibit room of 70 people, there were 18 teachers and 52 principals. What prediction can you make about the number of principals in attendance at the conference?

There were about 167 principals in attendance.
There were about 316 principals in attendance.
There were about 483 principals in attendance.
There were about 1,878 principals in attendance.

Answers

So first you divide 650 by 70 so that you know how many rooms there are. The answer is about 9. Then you multiply 9 by the number of principals, so that you know how many principals there are in total. 52x9= about 483. This means the answer is that there were about 483 principals.

There were about 483 principals in attendance.

The correct option is (3).

What is Arithmetic?

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data:

The total number of people in the recent conference = 650

The total number of people in one exhibit room = 70

Number of teachers in one exhibit room = 18

Number of principals in one exhibit room = 52

To find out the total number of exhibit rooms:

= Total number of people in the conference / total people in one room

= 650 / 70

= 9.28 = 9 {rounding off to the nearest integer}

Number of principals in one exhibit room = 52

Total number of principals in the conference:

= Number of rooms × Principals in one room

= 9 × 52 = 468 which is equal to 483 {approximate answer}

There were about 483 principals in attendance.

Hence, There were about 483 principals in attendance.

Answers

Answer:

The slope is -3

8b + 16

2(6m +2)

I'm not really sure what the letters stand for in this context

Answers

the letters are a variable, when you have different variables you cannot plus or minus them like in this situation - 8b + 16

16 has no b's for plus 8b

2(6m +2) - in this expression we can multiply in which is 12m + 4

Ok so the letters are variables also can indicate any number so in the 8b+16 it is telling you that 8 times any number plus sixteen. And for the other variable m it is standing for when you multiply 2 times 6m which is 12m and then 2 times 2 which is four, so the inquisition for this equation would be 12m+4
