Answer:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.
This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read;
Average, otherwise known as the mean is the calculated 'central' value of a set of numbers;
The formula for mean is given by;
mean=(sum)/(count)
in our case:
sum=18,996
count=650
thus;
mean=18996/650
=29.23
Here we can conclude that the average number of pages read by each student in the High School was 29.23
To answer this question, we first have to set up an equation with variables.
We can use "x" to represent the cost of each bracelet.
Equation: number of bracelets bought × cost of each bracelet = total cost
Number of bracelets bought: 7
Total Cost: 49
Using this information, we can fill in the equation and solve for x.
7x = 49
To isolate x, divide both sides by 7.
x = 7
Since x equals 7, we now know that each bracelet cost $7.
Answer:
62.5.
Step-by-step explanation:
Given:
The expression to simplify is given as:
55 - 4.5 +12
We have to use PEMDAS method in order to simplify this.
P stands for parenthesis, E for exponents, M/D stands for Multiplication or Division and A/S stands for Addition or Subtraction.
P has the highest priority followed by E followed by M or D which ever comes first followed by A or S which ever comes first.
Here, the first operation we encounter is subtraction S.
First, we will subtract 4.5 from 55. So, 55 - 4.5 = 50.5
Next operation is addition A.
Now, we will add the result to 12. So, 50.5 + 12 = 62.5
Therefore, the answer is 62.5.
