The figure shows five points. A point has been translated right and up

Answers

A point has been translated right and up from point D could be the image of B.

It indicates that a point was translated right and up.

As a result, any point existing on the rightmost side cannot be the translated point.

As a result, points E and D are ruled out.

There is no point that is higher than point A.

As a result, no "up" translation is available for point A.

Only points C and B are capable of "right and up" movement.

As a result, the first option "Point D could be the image of B" is correct.

A

Answer:

Option a. $2077.88 is the correct answer.

Step-by-step explanation:

Your housing and fixed expenses are $685.70 per month.

If they are 33% of your realized income.

Let your realized income per month be x

33% of x = $685.70

[tex]\frac{33}{100}[/tex] of x = 685.70

0.33x = 685.70

x = 685.70 ÷ 0.33 = 2,077.8787 rounded to $2,077.88

Your realized income per month would be $2,077.88.

Which equation is a point slope form equation for line AB?

a) y−2=−2(x+6)
b) y−2=−2(x+2)
c) y−6=−2(x+2)
d) y−2=2(x+2)

Answers

Answer:

the answer is c

Step-by-step explanation:


Answer:

c) y−6=−2(x+2)

Step-by-step explanation:

The general point slope form equation is:

y - y1 = m*(x - x1)

where x and y are the variables, (x1, y1) is the coordinate of a point on the line and m is the slope of the line.

To calculate the slope of the line we need two points on the line (x1, y1) and (x2, y2) and the following equation:

m = (y2 - y1)/(x2- x1)

Coordinates of point A: (-2, 6)

Coordinates of point B: (2, -2)

Replacing into the equation:

m = (6 - (-2))/(-2 - 2)

m = 8/(-4)

m = -2

Replacing this value and coordinate of point A into the general point slope equation we get:

y - 6 = -2*(x - (-2))

y - 6 = -2*(x + 2)

I just need the answers for 10 and 12

Answers

Answer:

10.) y = -5x + 7

12.) y = 3/2x - 8

Step-by-step explanation: Since you have to create a new line that us parallel, the slopes will be equivalent. So the mx value will not change. Now we can plug in the coordinates to find the value of b.

10.)

2 = -5(1) + b.

2 = -5 +b

b = 7

therefore...

y = -5x + 7


12.)

2(-5) = 3(2) + b

-10 = 6 + b

b = -16

therefore...

2y = 3x - 16

simplified:

y = 3/2x - 8

a math club earns $2,080 from selling 62 floor seats and 120 Stadium seats to a lip sync Talent competition at the floor seats cost twice as much as Stadium seats find the price of each ticket

Answers

Answer:

Price of floor seat =$ 17 and

Price of stadium seats = $8.5

Step-by-step explanation:

Let x represents the cost of floor seats and y represents the cost of stadium seats.

Then, from the given condition, we have;

Total cost for selling floor seats =  62x  and the total cost for stadium seats = 120y.

Since, a math club earn $2,080.

62x + 120y = 2080                         .....[1]

Also, it is given that the floor seats cost twice as much as Stadium seats.

⇒ x = 2y                                               .....[2]

Substitute this equation [2] in [1] we get;

[tex]62(2y) + 120y = 2080[/tex]

Simplify:

124y + 120y =2080

Combine like terms;

244y =2080

Divide both sides by 144 we get;

[tex]y = \frac{2080}{144} = 8.5[/tex]

y = $8.5

Substitute this in [2] we get x;

x = 2(8.5) = 17

i.e, x = $ 17

Therefore, the price of floor seat is, $ 17 and the price of stadium seats is, $8.5


To convert 3 square feet to square centimeters, multiply 3 by 9.29 × 10-2
True
False

Answers

Final answer:

To convert 3 square feet to square centimeters, multiply by the correct conversion factor of 9.29 × 10⁻².

Explanation:

To convert square feet to square centimeters, you need to understand the conversion factor between these two units. Since 1 foot is equal to 30.48 centimeters and area is defined as the product of the two dimensions, you need to square the conversion factor of 30.48 to convert square feet to square centimeters.

So, the correct conversion factor is (30.48 cm/1 ft)².

To convert 3 square feet to square centimeters, you can use the conversion factor as follows:

(3 ft²) × (30.48 cm/1 ft)² = 274.32 cm²

Therefore, the statement is True as multiplying 3 by the correct conversion factor of 9.29 × 10⁻² will indeed give you the value of 274.32 square centimeters.

A storeowner orders 25 calculators that cost ​$48 each. The storeowner can sell each calculator for ​$60. The storeowner sold 22 calculators to customers. He had to return 3 calculators that were never sold and pay a ​$2 charge for each returned calculator​ (although the initial cost is​ refunded). What is the​ storeowner's profit?

Answers

25*48=1,200

So we start at -1,200

22*60=1,320

So currently we are at a profit of $120.

120-6=114


Total profit: $114

Final answer:

As per the given values, the storeowner's profit is $114.

Explanation:

Total number of calculators = 25

Cost of calculators = ​$48

The amount at which they can be sold = $60.

To calculate the storeowner's profit, we need to consider the total cost and total revenue.

First, calculate the total cost of the calculators:
25 calculators x $48 each
= $1200.Next, calculate the total revenue from the sale of the calculators:
22 calculators x $60 each
= $1320.Deduct the cost of the returned calculators:
3 calculators x $2 charge each
= $6.Finally, calculate the profit:
Total revenue - Total cost - Cost of returned calculators
= $1320 - $1200 - $6
= $114.

There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 6 or a multiple of 4?

Answers

Answer:

see below  PLEASE GIVE BRAINLIEST

Step-by-step explanation:

1  2  3  4  5  6  7  8  9  10  11  12  13  14  15  

BOLD number are multiples of 4 or 6

4 out of the 15 numbers are a multiple of either 4 or 6,

so the probablilty would be 4/15 or a 26.6% chance.

The probability that the result is a multiple of 6 or a multiple of 4 is 4 /15.

The spinner has 15 equal areas numbered 1 through 15.

If the spinner is spun one time the probability of getting a multiple of 6 or a multiple of 4 can be calculated below;

The numbered side are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15.

multiple of 6 are 6 and 12.

multiple of 4 are 4, 8 and 12

union of the set = 4, 6, 8, 12

number of acceptable value = 4

The probability of getting a multiple of 6 or a multiple of 4 = number of acceptable value / number of possible value

probability of getting a multiple of 6 or a multiple of 4 = 4 / 15 = 4 / 15

Use the Counting Principle to find the probability of rolling a 4 on each of 3 number cubes

Answers

Answer:

[tex]\frac{1}{216}[/tex]

Step-by-step explanation:

We have been given that three cubes are being rolled and we are required to find the probability of getting 4 on each of the three cubes.

We know the probability of rolling a 4 on one cube will be [tex]\frac{1}{6}[/tex]. Since there are 3 cubes, the probability of rolling 4 in each of the individual cubes will be [tex]\frac{1}{6}[/tex].

But we want 4 to be rolled on all three cubes at once, in order for that to happen, we need to get a four on first cube AND second cube AND third cube. Since there is AND between the events, we will multiplied their probabilities as per counting principle. Thus, the required probability of rolling 4 on each of the three cubes is [tex]\frac{1}{6}\cdot\frac{1}{6}\cdot\frac{1}{6}[/tex] which simplifies to [tex]\frac{1}{216}[/tex].

Michael and Imani go out to eat for lunch.

Part A
If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill?
Part B
If Michael and Imani add an 18% tip to the bill, what does their lunch cost in total?

Answers

Answer:

Part A: $27.32

Part B: $32.24

Step-by-step explanation:

Part A:

$25.30 is the cost, since we are increasing it by the 8% meals tax, we are going to do 25.3 * the decimal form of 8%, or 0.08, plus one so that we already have our 25.3 factored in. Which equals 25.3 * 1.08, which equals 27.324, which we round to $27.32.

Part B:

We take our $27.32 and we times it by 1.18 for the reason stated above, which equals 32.2376, which is rounded to $32.24.

A. The bill would be $27.32, plus tax

Explanation:
1. We need to find 8% of 25.30
2. To do so, we need to cross multiply
3. 25.30/100 = x/8 (percents on the bottom, price on the top)
-multiply 25.30 by 8 to get 202.4
-divide 202.4 by 100 to get 2.024
4. Add the two together!
-25.30 plus 2.024 is is 27.32 (rounded)


B. The total cost of lunch would be $32.24 (plus tax and tip)

Explanation:
1. We need to find 18% of 27.32
2. To do so, we need to cross multiply
3. 27.32/100 = x/18
-multiply 27.32 by 18 to get 491.76
-divide 491.76 by 100 to get 4.9176
4. Add 4.9176 and 27.32 to get 32.24 (rounded)
