Store B advertises that it is reducing the television’s price by $250. When Allison compares the sale prices of the television in both stores, she concludes that the sale prices are equal. Let p represent the television’s original price. Which equation models this situation? 0.7(p−250)=p 0.3=p−250 0.7p=p−250 0.3p = p + 250

Answers

30% off so sale price is 70%

 so 0.7p = p-250

Answer:

Musiclover10045 is correct! I took the test and the correct answer is in fact:

A catapult launches a boulder with an upward velocity of 112 ft/s. The height of the boulder, h, in feet after t seconds is given by the function h = -16t2 + 112t + 30 How long does it take the boulder to reach its maximum height? What is the boulder’s maximum height? Round to the nearest hundredth, if necessary

Answers

The expression for the height is given in quadratic expression form

Ax² + Bx + C

Where A, B, and C are constant

To find the x-coordinate when the graph reaches maximum/minimum, we use the formula

x = -B ÷ 2A

We have

h = -16t² + 112t + 30
The value for A = -16, B = 112, and C = 30

Substitute these into x = -B ÷ 2A we have
t = -112 ÷ (2×-16) = 3.5

The maximum height is reached when t = 3.5 sec 

The height when t = 3.5 sec is given
h = -16(3.5)² + 112(3.5) + 30 = 226 feet

Answer:

3.5 s; 226 ft is correct.

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.

How can area models be used to solve multiplication problems?

Answers

Final answer:

Area models can be used to solve multiplication problems by representing the problem visually using rectangles or squares. The areas of these shapes can then be calculated to find the product.

Explanation:

Area models can be used to solve multiplication problems by representing the problem visually using rectangles or squares. The areas of these shapes can then be calculated to find the product.



For example, if we want to multiply 3 by 4, we can create a rectangle with a length of 3 units and a width of 4 units. The area of this rectangle is 3 * 4 = 12 units squared, which is the product of the two numbers.



Area models can also be used to solve more complex multiplication problems by breaking them down into smaller areas and summing them up.

Final answer:

Area models are visual representations of multiplication that use rectangular shapes to represent the dimensions of the problem. They help students better understand the concept of multiplication and visualize how it works.

Explanation:

An area model is a visual representation of multiplication that uses rectangular shapes to represent the dimensions of the problem.

For example, if you want to multiply 3 by 4, you can draw a rectangle with a length of 3 units and a width of 4 units.The area of the rectangle will then give you the product of the multiplication, which in this case is 12.Area models can also be used to solve more complex multiplication problems by breaking them down into smaller, easier-to-visualize steps.

By using area models, you can better understand the concept of multiplication and visualize how it works.

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

The value of function f(x)=-3x-2 are as follows:

a. f(3) = -11

b. f(-1) = 1

c. f(-2) = 4

To find the values of the function \(f(x) = -3x - 2\) at specific points, substitute the given values of \(x\) into the function:

a. f(3)

  Substitute x = 3 into the function:

  f(3) = -3(3) - 2 = -9 - 2 = -11

Answer:

False

Step-by-step explanation:

Hi there!

The domain refers to the possible x-values in a function.

The first element refers to the first member in a set of data (example: In the set {1, 2, 3}, 1 is the first element).

The y-value of a coordinate refers to the y-coordinate (example: In the ordered pair (4,9), 9 is the y-value or y-coordinate).

Therefore, the three terms all have different meanings.

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

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.

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.

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

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

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.
