Have a great day/night!

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:

Selena drove more miles after rest stop

And drove 13.24 mi more before before she stopped.

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.

The perimeter of figure 1 is 15 units.

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

= 23 units

Figure 4,

Perimeter = 4+3+3+3+3

= 16 units

Figure 5,

Perimeter = 3+3+2+2+2+2+8

= 22 units

Therefore, the perimeter of figure 1 is 15 units.

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

Answer:

A. The rectangular prism will have a perimeter of 32 centimeters along the base.

Step-by-step explanation:

When your looking for perimeter, you don't use the height, however, you have to take into account the half sized cubes, in order to get an accurate perimeter, you have to multiply everything by it's multiplicative inverse in order to fill everything with the cubes. Thus, the first option makes the most since you have to double the height and length, when you do so, you get 10 10 6 and 6. You then add them together to get 32.

I really hope this makes since and that I didn't get it wrong. Have a good day and Good luck!

Answer:

Neither A not B. It's C

Step-by-step explanation:

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.

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

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
