Two stores sell the same television for the same original price. Store A advertises that the television is on sale for 30% off the original price. 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
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:
0.7p = p - 250!
Thanks, mate!
Cheers!
Explain why each relationship is not proportional
X needs to be multiplied by the same number each time to get Y. Each time you have to multiply X to get Y, the number you have to multiply by is different. If the relationship was proportional, you could take one number and multiply it by X to get Y.
Ex.
X= 2, 6, 8, 12, 18
Y= 1, 3, 4, 6, 9
The rule there is that you have to multiply X by 2 to get Y.
Hope this helps!
A relationship is not proportional when the variables involved do not exhibit a constant rate of change or when the pattern on a graph deviates from a straight line.
Explanation:When a relationship is not proportional, it means that the variables involved do not change at a constant rate. There can be various reasons why a relationship is not proportional:
Scatter or uncertainty: In some cases, the data points representing the relationship scatter widely on a graph, indicating a lack of a straight line relationship. This can happen when there are external factors influencing the relationship.Non-linear patterns: Certain relationships, such as the period-luminosity relation for variable stars, do not follow a straight line on a graph. The points representing the stars may not fall along a single line, indicating a non-linear relationship.Unequal fractions: When analyzing relationships, fractions of the total force or variation may not be equal. This indicates that the relationship is not proportional. While it is possible for the fractions to be equal, it is more common for them to be unequal.Overall, a relationship is not proportional when the variables involved do not exhibit a constant rate of change or when the pattern on a graph deviates from a straight line.
How can area models be used to solve multiplication problems?
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.
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.

Based on this information, should the company build the mousetrap?
A) The expected value is $70,000, so the company should build the mousetrap.
B) The expected value is $85,000, so the company should build the mousetrap.
C) The expected value is $100,000, so the company should build the mousetrap.
D) The expected value is -$70,000, so the company should not build the mousetrap.

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.
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
if you needed to triple a recipe, would the ratio change? Explain.
Domain, first element, and y -value all have the same meaning.
True Or False
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.

given f(x) =-3x-2 find the following
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
b. f(-1)
Substitute x = -1 into the function:
f(-1) = -3(-1) - 2 = 3 - 2 = 1
c. f(-2)
Substitute x = -2 into the function:
f(-2) = -3(-2) - 2 = 6 - 2 = 4
So, the values of the function f(x) = -3x - 2 at x = 3, x = -1, and x = -2 are:
a. f(3) = -11
b. f(-1) = 1
c. f(-2) = 4

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

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?
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.
