It shows you the exact distance from each number and it's easier to find out how far apart they are.
Answer:
20
Step-by-step explanation:
Given:
A rectangle has a length of 8 and a width of 4.
Four equal rectangles are drawn within that rectangle, creating the longest lengths possible for the rectangles.
To find:
The sum of the perimeters of two of these equal rectangles.
Solution:
We have to draw 2 lines which are bisecting the length and width respectively, to divide a rectangle in 4 equal parts with longest lengths.
Half of length 8 = 4
Half of width 4 = 2
It means each rectangle have a length of 4 and a width of 2.
Perimeter of a rectangle is
So, perimeter of each equal rectangle is 12 units.
Sum of the perimeters of two of these equal rectangles is
Therefore, sum of the perimeters of two of these equal rectangles is 24.
Answer:
Stefan spend originally $110 and the money stefan make by selling the bicycle and helmet to jin is $22 .
Step-by-step explanation:
As given
Stefan sells jin a bicycle for $114 and a helmet for $18.
Total cost of the bicycle and helmet = $114 + $18
= $132
The total cost for jin is 120% of what stefan spent originally to buy the bike and helmet.
120% is written in the decimal form.
= 1.20
Let us assume that the Stefan spend originally for bike and helmets be x.
Than the equation becomes
1.20 × x = 132
1.20x = 132
x = $110
Therefore stefan spend originally be $110 .
Now find out how much money did he make by selling the bicycle and helmet to jin .
Money make by Stefan = Total selling cost of helmet and bicycle - Total amount of stefan spends for purchasing.
Money make by Stefan = 132 - 110
Money make by Stefan = $22
Therefore the money stefan make by selling the bicycle and helmet to jin is $22 .
