100 POINTS IF YOU ANSWER CORRECTLY Rotate these coordinates 180 around the origin and then translate 6 units to the left.

Answers

Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)

A 180 degree rotation around the origin flips the signs of x and y, so you get:

(2, 8) (6, 8) (11, 1) (7, 3)

Then a translation to the left 6 units just subtracts 6 from all the x values:

(-4, 8) (0, 8) (5, 1) (1, 3)

Answers

Need to find 1/5 of 1 2/5 so 1 2/5 times 1/5 =  1 2/25 
Now we add 1 2/5 + 1 2/25 = 2 12/25
Now add 1 2/5 + 2 12/25 =  3 (22/25)

Answer:

[tex]1\frac{17}{25} \\[/tex] bags

Step-by-step explanation:

Number of bags used by Jared for his garden

[tex]= 1\frac{2}{5} \\= \frac{7}{5}\\[/tex]-------------------------- Eq (A)

Number of bags of soil required for new garden

[tex]= \frac{1}{5} * \frac{7}{5} \\= \frac{7}{25} \\[/tex]-------------------------- Eq (B)

Total number of bags that will be used

Community Gym charges a $40 membership fee and a $50 monthly fee. Workout Gym charges a $210 membership fee and a $40 monthly fee. After how many months will the total amount of money paid to both gyms be the same? What will the amount be?

Answers

Final answer:

To find the number of months it will take for the total amount of money paid to both gyms to be the same, set up an equation and solve for x. After 17 months, the total amount paid to both gyms will be $870.

Explanation:

To find the number of months it will take for the total amount of money paid to both gyms to be the same, we need to set up an equation and solve for x. Let x represent the number of months.



For Community Gym, the total cost after x months is: 40 (membership fee) + 50x (monthly fee).



For Workout Gym, the total cost after x months is: 210 (membership fee) + 40x (monthly fee).



Setting up the equation:



40 + 50x = 210 + 40x



10x = 170



x = 17



After 17 months, the total amount of money paid to both gyms will be the same, which is $870.

a car travels an average speed of 64 miles per hour. how many miles does it travel in 5 hours and 15 minutes?

Answers

Distance is speed or velocity multiplied by time: d = v * t

We know the speed of the car and the time it travelled, so input the two into the equation above and solve for the distance travelled.

d = v * t

d = 64 m/h * (5 hours and 15 minutes) = 64 m/h * (5.25 hours)

d = (64 * 5.25) miles


d = 336 miles

Answers

I heard that before, where did you see that, and 10 packs

Answer:

Package 10−pack of 2.3 ounce bars has the better price per bar

Step-by-step explanation:

Case 1) Package 10−pack of 2.3 ounce bars Cost ($) 17.35

Cost of Package 10−pack of 2.3 ounce bars = 17.35

Cost of Package 1−pack of 1 ounce bars = [tex]\frac{17.35}{10 \times 2.3}[/tex]

                                                                   = [tex]0.7543[/tex]

2)  12−pack of 1.6 ounce bars Cost ($)16.97

Cost of Package 12−pack of 1.6 ounce bars = 16.97

Cost of Package 1−pack of 1 ounce bars = [tex]\frac{16.97}{12 \times 1.6}[/tex]

                                                                   = [tex]0.8838[/tex]

explain why two employees at a company, earning the same gross pay, might have different net pays.

Answers

There could be extra tips or they could be taxed differently

Step-by-step explanation:

Gross pay:

  Gross pay can be define as the wage before paying any taxes and all other deductions.

Net pay:

 Net pay can be define as the wages after paying all taxes and all other deductions.

So we can say that

Gross pay = Net pay +   taxes and all other deductions

So from above equation we can say that ,even two employees have same gross pay but can have different net pays .Because maybe they are paying different taxes and other deductions.

7x + 55 ≥ 300. Solve this inequality for x.
identify a number of pages that the student could read per day in order to have at least 300 pages of the novel read in a week.

Answers

The number of pages is 35

To solve the inequality 7x + 55 ≥ 300 for x, we first subtract 55 from both sides to isolate the term with x:

7x + 55 - 55 ≥ 300 - 55

7x ≥ 245

Divide by 7 to solve for x:

x ≥ 35

This means the student needs to read at least 35 pages per day to have 300 pages of the novel read in a week.

The Jensen family took a trip in September. Sally is calculating the gas mileage in miles per gallon for her dads SUV. When he fills the tank ,her dad records the miles on the SUV as 24033. Her dad pays $83.58 I fill up the empty gas tank of the SUV. At the destination, there was a quarter tank of gas left in the vehicle and the miles where recorded as 24,297. Use a ratio equation to determine the gas mileage in miles per gallon for the trip. Round your answer to the nearest whole.

Answers

Answer:

The gas mileage formula in miles per gallon (mpg) is:



[tex]gas mileage=\frac{miles driven}{gallons used}[/tex]   (1)



We know that Sally’s dad filled the tank when it was empty and the miles recorded in the SUV were 24033 miles.



We also know that at the destination, there was a quarter tank of gas left in the vehicle and the miles were recorded as 24297 miles.  


This means that the miles driven during the whole trip were 894 miles:



[tex]24927 miles-24033 miles=894 miles[/tex]



If at the beginning the tank was full and at the end is left with a quarter tank ([tex]\frac{1}{4}[/tex]), this means that the car wasted [tex]\frac{3}{4}[/tex] of the tank:



[tex]\frac{4}{4}-\frac{1}{4}=\frac{3}{4}[/tex]




Now, SUVs come in so many different sizes and models, hence it is difficult to assume an average size for a SUV gas tank. It may vary from the smaller ones that hold 16.5 gallons to larger SUVs that hold from 28 to 33.5 gallons.


In this case let’s assume that the tank holds 28 gallons


Then, if 1 tank holds 28 gallons, [tex]\frac{3}{4}[/tex] of a tank holds 21 gallons.



Knowing this, let’s apply the mileage formula ( equation 1):



[tex]\frac{894 miles}{21 gallons}=42.571mpg[/tex]    


If we round the result we have, the gas mileage in miles per gallon for the Jensen’s SUV is 43mpg

Just as subtraction is the inverse operation of addition and division is the inverse operation of multiplication, the square root operation is the inverse of the squaring operation.

Algebraically, you can see the analogues between operations and their inverses:

Addition solves problems like 6 + 7 = x, while subtraction solves problems like 6 + x = 7

Multiplication solves problems like 7 * 5 = x, while division solves problems like 5x = 7

Squaring solves problems like 2^2 = x, while square rooting solves problems like x^2 = 2

7 teachers share 1 liter of cappuccino. If you make 3 litters of cappuccino, how many teachers can drink cappuccino? If you need to make enough cappuccino for 74 teachers, how many liters would you need to make?

Answers

Part A - If you make 3 liters of cappuccino for the teachers and want to find out many teachers drink from the liter, you need to find the unit rate which is 7 Teachers to 1 Cappuccino. So, that means it is 21 teachers can drink 3 liters. 

Part B - For this part, you have to do 74 divided by 7 which rounds to about 10.57.
Final answer:

If 3 liters of cappuccino are made, 21 teachers can drink it. To have enough cappuccino for 74 teachers, approximately 10.57 liters would be needed.

Explanation:

To answer the first part of the question, we can use a proportion to find out how many teachers can drink cappuccino if 3 liters are made. Since 7 teachers share 1 liter, we can set up the proportion: 7 teachers / 1 liter = x teachers / 3 liters. Solving for x, we get x = 21 teachers. Therefore, 21 teachers can drink cappuccino.

For the second part of the question, we can use a similar proportion to find how many liters of cappuccino would be needed for 74 teachers. From the previous proportion, we know that 7 teachers share 1 liter. So, we can set up the proportion: 7 teachers / 1 liter = 74 teachers / x liters. Solving for x, we get x = 10.57 liters. Therefore, you would need to make approximately 10.57 liters to have enough cappuccino for 74 teachers.

Make a conjecture given that points A,B,C are collinear and AC+ CB=AB

1. C is between A and B
2. A is between B and C
3. B is between A and C
4. ABC is equilateral

Answers

The points A, B and C are collinear and AC + CB = AB.
From that, we can conclude that C is between A and B. Because if you split AB, C will appear (AB = AC + CB).

Hope this helps! :)
Final answer:

The points A, B, C cannot be both collinear and form an equilateral triangle simultaneously. This is proven by applying the Pythagorean theorem and trigonometry laws for triangles, which show that the distances and angles do not match the requirements for an equilateral triangle if the points are collinear (on a straight line).

Explanation:

Given that points A,B,C are collinear and you've stated a variety of scenarios about the positioning of these points. Combining all these restrictions, however, leads to a contradiction. An equilateral triangle's points cannot all be collinear as you've mentioned in your last point. A collinear set of points exists on the same straight line. The points of an equilateral triangle do not fall on the same line. Therefore, it's impossible for points A,B,C to be collinear and also form an equilateral triangle ABC.

Applying the Pythagorean theorem to the positions of these points, we see that the distances on the sides of the triangle will not be equivalent if they are positioned in a straight line. Similarly, with the use of trigonometry laws for triangles, such as the ones for vector equations, the same result is found. The vector equations for collinear points lack the trigonometric components found in equilateral triangles.

A dress is 10 marked down by 20% and placed on a clearance rack on which is posted a sign take an extra 40% off already reduced merchandise. What fraction of the original price is the final sales price of the dress?

Answers

The answer would be $4.80

The final sales price of the dress is a fraction 12/25 of the original price after successive discounts of 20% and 40%.

To determine the final sales price of the dress after multiple discounts, we can apply each discount successively. Let's assume the original price of the dress is $10, as mentioned in the premise, although this might be a typo or an example figure since a dress would typically cost more.

First discount: 20% off the original price, which is 0.20 x 10 = $2. So the new price after the first discount is $10 - $2 = $8.

Second discount: An additional 40% off on the already reduced price of $8. The additional discount is 0.40 x 8 = $3.20. Therefore, the final sales price after the second discount is $8 - $3.20 = $4.80.

To find the fraction of the original price that the final sales price represents, we divide the final price by the original price: $4.80 / $10 = 0.48. Thus, the fraction of the original price is [tex]\frac{48}{100}[/tex] or 24/50 after simplification, which further simplifies to  12/25
