The perimeter of figure 1 is 15 units.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
Figure 1,
Perimeter = 3+3+3+6
= 15 units
Figure 2,
Perimeter = 4+2+2+4+2+2= 16 units
Figure 3,
Perimeter = 8+15

Step-by-step explanation:
D=vt
where D=distance,v=velocity and t=time
Distance befoe stopped
D1=50.55mph *1.75 hr =88.46
Distance after stopped
D2 =45.2mi* 2.25 hr=101.7mi
The difference is:
101.7-88.46 = 13.24 mi
Then the answer would be:

An employee at a gift shop earns $72.00 for working 9 hours. At this hourly rate, what should the employee earn for a 40-hour work week?
A.$8.00
B.$48.00
C.$121.00
D.$320.00
At this hourly rate, the employee earns a 40-hour workweek is D.$320.00
In the above case, an employee earns $72.00 for working 9 hours a day or 9 hours, now to know about hourly earing we should divide $72.00 by 9 hours so that we can get the earnings of the employee on an hourly basis.
Therefore, earnings an hour = 72.00/9 = 8, which means the employee is earning 8 dollars for every hour he works at the gift shop, now to know how much money he/ she will generate in 40 hours we will multiply 8 dollars with 40 working hours.
Therefore total earnings of the week = earning per hour * total working hours = 8*40 = $320.00 for every 40-hour week. hence, the total earnings for the week will be $320,
Calculations
earning per hour =72.00/ 9 = 8
total earning = 40*8 = 320
correct option will be D. $320

5m + 8 and -2m - 6. Could i get the answer and an explanation?
Answer:
m=-5
Step-by-step explanation:
Simplifying
5m + -6 = 8m + 9
Reorder the terms:
-6 + 5m = 8m + 9
Reorder the terms:
-6 + 5m = 9 + 8m
Solving
-6 + 5m = 9 + 8m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-8m' to each side of the equation.
-6 + 5m + -8m = 9 + 8m + -8m
Combine like terms: 5m + -8m = -3m
-6 + -3m = 9 + 8m + -8m
Combine like terms: 8m + -8m = 0
-6 + -3m = 9 + 0
-6 + -3m = 9
Add '6' to each side of the equation.
-6 + 6 + -3m = 9 + 6
Combine like terms: -6 + 6 = 0
0 + -3m = 9 + 6
-3m = 9 + 6
Combine like terms: 9 + 6 = 15
-3m = 15
Divide each side by '-3'.
m = -5
Simplifying
m = -5

81 is 18% of what number?
Enter your answer in the box.
Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
Answer:
450
Step-by-step explanation:
18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.

You'll have to visualize it.
Think about this as a cake on a table.
You want to eat the top — so you slice across horizontally.
When you have just the bottom left on the table, you will have a rectangle shape
Another hint is that the question says a "right rectangular pyramid". So no matter how you slice a pyramid, the bottom of each slice will look the same as the name. In this case "rectangular"
PS: I've attached a sketch of what it looks like before & after slicing.
Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)
Answer:
Perimeter of a square=circumference of circle
4×22=2πr
44=πr
r=14
Area of circle=πr2
22/7×14×14
28×22
616
Answer:
176cm²
Step-by-step explanation:
Side of square = 22cm
Perimeter of square = 88cm
Circumference of circle = perimeter of square
2π r = 88cm
2 x 22/7 x r = 88cm
44/7 x r = 88cm
r = 88 x 7/44
r = 14cm
Area of circle = π x r x r
= 22/7 x 14 x 14
= 44 x 4
= 176 cm²
