Answer:
the answer is C......................
The result of the simplified expression in this problem is given as follows:
D. 15.
How to simplify the expression?The expression for this problem is defined as follows:
2³ + 6/3 - (-10/2)
The parenthesis takes precedence, hence:
2³ + 6/3 - (-5) = 2³ + 6/3 + 5
The power takes precedence, hence:
8 + 6/3 + 5
Division has higher precedence than addition, hence:
8 + 2 + 5.
Hence the result is given as follows:
8 + 2 + 5 = 15.

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.
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.

PLEASE HELP AND ANSWER ALL QUESTIONS IF YOU CAN PLS AND TY.
Answer:
(-1,2.5) is on the line.
(11,10) is on the line.
(70,40 is not on the line.
(-2, 1.875) is on the line.
Step-by-step explanation:
First, find the equation of the line. Two write an equation in the slope -intercept form of the line we need a slope and the y-intercept. We can find this from the 2 points given (-5,0) and (3,5). The ordered pair is written in the from (x,y) The first number is how much we move right or left from the origin (0.0) and the second number tells us how much we move up or down from the origin (0,0).
To find the slope, we find the change in y over the change in x.
[tex]\frac{(5-0)}{3 - -5)}[/tex] = [tex]\frac{5}{3+ 5}[/tex] = [tex]\frac{5}{8}[/tex] Now we can use either of the points to find the y-intercept. Let's use (3,5)
slope = [tex]\frac{5}{8}[/tex]
x = 3
y =5
y=mx + b plug in what we know
5 = [tex]\frac{5}{8}[/tex](3) + b This is the same as writing
5 = [tex]\frac{5}{8}[/tex][tex](\frac{3}{1})[/tex] 3 and [tex]\frac{3}{1}[/tex] mean the same thing
5 = [tex]\frac{15}{8}[/tex] + b Now subtract [tex]\frac{15}{8}[/tex] from both sides of the equation
[tex]\frac{5}{1}[/tex] - [tex]\frac{15}{8}[/tex] = [tex]\frac{15}{8}[/tex] - [tex]\frac{15}{8}[/tex] + b
[tex]\frac{40}{8}[/tex] - [tex]\frac{15}{8}[/tex] = b
[tex]\frac{25}{8}[/tex] = b Now we can write the equation
y = mx + b
y = [tex]\frac{5}{8}[/tex] x + [tex]\frac{25}{8}[/tex]
N ow that we have the equation, we can plug in the (x,y) and see if the equation is true or not. If the equation is true, the point is on the line.
(-1,2.5)
y = [tex]\frac{5}{8}[/tex] x + [tex]\frac{25}{8}[/tex]
2.5 = [tex]\frac{5}{8}[/tex](-1) + [tex]\frac{25}{8}[/tex]
2.5 = [tex]\frac{-5}{8}[/tex] + [tex]\frac{25}{8}[/tex]
2.5 = [tex]\frac{20}{8}[/tex]
2.5 = 2.5
Yes, point (-1, 2.5) is on the line.
(11,10)
y = mx + b
10 = [tex]\frac{5}{8}[/tex](11) + [tex]\frac{25}{8}[/tex]
10 = [tex]\frac{55}{8}[/tex] + [tex]\frac{25}{8}[/tex]
10 = [tex]\frac{80}{8}[/tex]
10 = 10
Yes, point (11,10) is on the line.
(70,40)
y = mx + b
40 = [tex]\frac{5}{8}[/tex](70) + [tex]\frac{25}{8}[/tex]
40 = [tex]\frac{350}{8}[/tex] + [tex]\frac{25}{8}[/tex]
40 = [tex]\frac{375}{8}[/tex]
40 ≠ 46.875
Point (70,40) is not one the line.
(-2, 1.875)
y = mx + b
1.875 = (-2)[tex]\frac{5}{8}[/tex] + [tex]\frac{25}{8}[/tex]
1.875 = [tex]\frac{-10}{8}[/tex] + [tex]\frac{25}{8}[/tex]
1.875 = [tex]\frac{15}{8}[/tex]
1.875 = 1.875
Point (-2, 1.875) is on the line.

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
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.
