The distance between the elementary school and the middle school is 4 miles. On the map, the two locations are One-half inch apart. What is the scale of the map?
1 inch = 8 miles
1 inch = StartFraction 1 over 8 EndFraction mile
One-half inch = 1 mile
4 inches = 1 mile
1 inch = 8 miles
1/2in + 1/2in = 1in
4 + 4 = 8

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.

What is the image of the point (24, 6), when rotated through 90 degrees clockwise? *
(-24, -6)
(24, 6)
(6, -24)
(-24, 6)
Answer:
6,-24 is our NEW IMAGE.
Step-by-step explanation:
OUR PRE-IMAGE is currently in QUADRANT 1
moving 90 degrees clockwise moves it into the QUADRANT 4.
In a 90 DEGREE rotation, we have to SWITCH THE x, and Y.
6,24 is our new values after switching the x and y.
Now we can use the quadrant rules,

If a value of 80.4° is added to the data, how does the range change?
The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48

E 490 centimeters
Answer:
D: 411 centimeters
Step-by-step explanation:
Multiply 8 by 15 you'll get 120 inches from thisMultiply that by 2.54 to find how many centimeters it is. It would be 304.8 centimeters.Then repeat steps 1-2 but replace 15 inches with 20 inches. When you multiply it by 8 it becomes 160 and it becomes 406.4 centimeters when it's multiplied by 2.54 which is why the correct answer is DA prepaid cell phone charges a preset number of minutes to use text messaging.

1) A container with 2 5⁄6gallons of weed killer can spray 3 5⁄6lawns.How many gallons would it take to spray 3 lawns?
2)It takes 3 2⁄6spoons of chocolate syrup to make 2 3⁄5gallons ofchocolate milk. How many spoons of syrup would it take to make 4gallons of chocolate milk?
Answer:
51/23 or 2 5/23
Step-by-step explanation:
2 5/6= 17/6
3 5/6= 23/6
17/6÷23/6
17/6×6/23=
17/23=1 lawn
17/23×3=51/23
A container with gallons of weed killer can spray = lawans
∵ in lawn the week killer can spray = gallons
∴ in 1 lawn the weed killer is used = × gallon
∴ in 3 lawns the weed killer can spray = × × 3 = gallon = gallons
Answer:
1. 2 5/23 gallons
2. 5 5/39 spoons of syrup
Step-by-step explanation:
1. A container with 17/6 gallons of weed killer can spray 23/6 lawns. We need to figure out how much weed killer it would take to spray 3 lawns. Divide 17/6 by 23/6.
17/6 / 23/6
17/6 * 6/23
The two 6's cancel out.
17/23 * 3/1
51/23
It would take 2 5/23 gallons to spray 3 lawns.
2. It takes 20/6 spoons of chocolate syrup to make 13/5 gallons of chocolate mink. We need to know how many spoons of syrup it would take to make 4 gallons of chocolate milk.
20/6 / 13/5
20/6 * 5/13
10/3 * 5/13
50/39
(50 * 4)/39
200/39
It would take 5 5/39 spoons of syrup to make 4 gallons of chocolate milk.
Petra is making a batch of extra large donuts by stamping circles in dough using a pastry stamp with a diameter of 5 inches. For the donut hole, she stamps out a circle using a pastry stamp that has a diameter of 2 inches.
How many square inches of dough are left in the donut after the hole has been removed?
Step 1 - Find the radius of each circle
Step 2 - Find the area of the large circle
Step 3 - Find the area of the small circle
Step 4 - Area of large circle minus area of small circle
Area = \(\pi\)²
Describe how you solved this problem using complete sentences and include all relevant formulas and calculations. Use 3.14 for \(\pi\)
Answer:
16.49
Step-by-step explanation:
First we are going to find the area of the larger circle. You don't need to find the radius, you can just use the diameter(the radius is 2.5). 3.14 times 2.5 squared=19.63. Next, the radius of the smaller circle is 1. So, 3.14 ^1 squared=3.14 19.63 - 3.14= 16.49

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)
