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.

An aircraft carrier left Hawaii traveling west seven hours before a container ship. The container ship traveled in the opposite direction going 5 km/h slower than the aircraft carrier for six hours after which time the ships were 540 km apart. Find the aircraft carrier's speed.
As we know distance = rate*time
Aircraft carrier:
time is 13 hours, 7 hours before container ship left then the 6 hours container traveled.
Let s be speed of aircraft carrier
--> d = 13s
Container ship:
time is 6 hours
speed is 5 km/h slower, so s-5
--> d = 6(s-5)
Since they are going in opposite directions, add up the distances to find how far apart they are
--> 13s + 6(s-5) = 540
Now solve for s-
--> 13s +6s -30 = 540
--> 19s = 570
--> s = 30
Aircraft carrier was traveling at 30 km/h and container ship 25 km/h

Hector paid $105 for 6 tickets to a hockey game. Each ticket costs the same amount.
What was the cost of each ticket in dollars and cents?
Answer:
$17.5
Step-by-step explanation:
For this problem, you go through division.
Because the tickets cost the same amount, the total must be split equally between each one.
$105/6
If you are not allowed to use a calculator, then use long division.
6 goes into 105 a max of 17 times. (6*17 = 102)

The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel to the nearest whole inch?
Answer:
1271.7 inches.
Step-by-step explanation:
We know the diameter of the bike wheel is 27.
Radius of the wheel: 13.5 in.
The circumference of the wheel: 84.78
So let's say the distance traveled in 1 rotation. Based of on the circumference, we know that 1 rotation is 84.78.
So if the distance was traveled in 15 rotations we need to multiply 84.78 to 15. 84.78 x 15 = 1271.7.

Step-by-step explanation:
Angles A and B are complementary to each other. If m∠A = 37° and m∠B = (3x + 17)°, find the value of x.
x = 39
x = 21
x = 12
x = 6.7
The value of x is 12.
The correct option is (B).
What are Complementary Angles?Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle.
Two angles are said to be complementary if their sum is 90 degrees. By deducting an angle from 90, one can find its complement.
For instance, 90° - 40° = 50° is the complement of 40°.
Given:
m∠A = 37° and m∠B = (3x + 17)°
As, the sum of Complementary angle is 90.
<A + <B= 90
37 + 3x+ 17 = 90
3x + 54 = 90
3x = 36
x= 12
Hence, the value of x is 12.

Angles X and Y are supplementary. Angle X measures 126.25° and angle Y measures (m − 10)°. Find m∠Y.
53.75°
63.75°
107.5°
117.5°
The measure of angle y is 53.75°. Therefore, option A is the correct answer.
Given that, ∠x=126.25° and ∠y=(m − 10)°.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Here,
∠x + ∠y = 180°
⇒ 126.25°+(m − 10)° = 180°
⇒ (m − 10)° = 180°-126.25°
⇒ (m − 10)° = 53.75
⇒ m = 63.75°
So, ∠y=(m − 10)°= 53.75°
The measure of angle y is 53.75°. Therefore, option A is the correct answer.
