Wayward Shoes spends $13 making each pair of its slip-on sneakers. Last week, they sold 95 pairs of these sneakers for $45 each. How much profit did Wayward Shoes make last week?

Answers

Answer:

.

$3040

Step-by-step explanation:

Cost of production of these slip ons = 13 dollars

Sales price of slip ons = 45 dollars

Number of slip ons sold = 95

To get profit, subtract cost price from sales price price, and multiply by number sold.

Mathematically,

(45-13) x 95

= 32x95

= $3040

Wayward shoes made a profit of $3040

Answer: Wayward shoes made $3,040 as profit last week

Step-by-step explanation:

Cost price  for 95 pairs of sneakers = Cost of making a pair x Number of sneakers =$13 x 95=$1,235

Selling price of 95 pairs of sneakers = Cost of selling  a pair x Number of sneakers = $45 x 95=$4,275

Profit = Selling Price- Cost Price

= $4,275 - $1,235

=$3,040

Recall that the center of dilation is point J. On the logo, identify one or two line segments: that contain the center of dilation that do not contain the center of dilation that lie on a line that passes through the center of dilation Record the names of the line segments you identified and the category they belong to. What differences do you notice in the way these categories of line segments are mapped from the preimage to the image?

PLATO

Answers

Answer:

HA , LJ , and IK contain the center of dilation. Line segments that contain the center of dilation in the preimage also contain the center of dilation in the image. GF , HI , and KL do not contain the center of dilation. Line segments that do not contain the center of dilation in the pre image are mapped onto distinct lines parallel to the original, corresponding line segment. HL does not contain the center of dilation either but it does lie on a line that passes through the center of dilation. Line segments that lie on lines passing through the center of dilation in the preimage lie on the same lines in the image.

The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.

Answers

Answer: The solution is (3, -2)

This means that x = 3 and y = -2 pair up together.

=====================================================

Explanation:

The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).

-----------------

As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation

y = (-5/3)x + 3

y = (-5/3)*3 + 3

y = -5+3

y = -2

The first equation is confirmed. Let's check the second equation

y = (1/3)x - 3

y = (1/3)*3 - 3

y = 1 - 3

y = -2

Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.

Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.

Answers

The area of the circle will be 3.14 feet .

Question:-

Find the area of a circle with a diameter of 2 feet. Use 3.14 for π.

Answer:-

Given,

Diameter = 2 feet

Circumference = 2/2 = 1 feet

Now,

Area of a circle = πr²

= 3.14 × 1 × 1

= 3.14 feet

Hence , the circumference is 3.14 feet.

Answer:

Option D. y = 5x + 1

Step-by-step explanation:

From the question given above, the following data were:

Input (x) >>>>>> Output (y)

0 >>>>>>>>>>>> 1

1 >>>>>>>>>>>> 6

2 >>>>>>>>>>>> 11

3 >>>>>>>>>>>> 16

4 >>>>>>>>>>>> 21

To know the the correct answer to the question, we shall apply the equation given in each option to see which will satisfy the table. This can be obtained as follow:

For Option a

y = 3x + 3

x = 0

y = 3(0) + 3

y = 0 + 3

y = 0

y = 3x + 3

x = 1

y = 3(1) + 3

y = 3 + 3

y = 6

For Option b

y = 5x – 4

x = 0

y = 5(0) – 4

y = 0 – 4

y = – 4

y = 5x – 4

x = 1

y = 5(1) – 4

y = 5 – 4

y = 1

For Option c

y = 10x – 9

x = 0

y = 10(0) – 9

y = 0 – 9

y = – 9

y = 10x – 9

x = 1

y = 10(1) – 9

y = 10 – 9

y = 1

For Option d

y = 5x + 1

x = 0

y = 5(0) + 1

y = 0 + 1

y = 1

y = 5x + 1

x = 1

y = 5(1) + 1

y = 5 + 1

y = 6

From the illustrations made above, only option d satisfy the table. Thus, option d gives the correct answer to the question.

why can you NOT divide by zero? explain and write paragraph HELP ASAP PLEASE

Answers

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.

Answer:

you cant divide by nothing. zero has no value so be dividing by nothing. also your outcome would be nothing. hope this helps
