Answer:
Step-by-step explanation:
On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.
After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.
Therefore we can write the following equation: (Where d = number of days)
B = 10 + 8d
W = 0 + 9d = 9d
We are told that eventually they will sell the same amount which means
B = W
This means we can say,
10 + 8d = 9d
If we subtract 8d from both sides we get
10 = d
Therefore it will take 10 days for them to sell the same amount of cookie dough.
Answer: 10 days
10 + 8 x 10 = 90
9 x 10 = 90.
It will take 10 days for Ben and Winston to sell the same amount of cookie dough.

A sweater is on sale for $34.15 . If the markdown on the sweater is 45% off , what was the original cost for the sweater ? pls help me .
The complete cost of purchasing an asset is known as the original cost.The whole costs associated with purchasing and using an asset are taken into account when calculating its initial cost.
Find original cost ?Subtract the asset's cost from its salvage value (what you anticipate it to be worth at the end of its useful life) to determine depreciation using the straight-line technique.The amount that can be depreciated, or the depreciable basis, is the outcome.Subtract this sum from the asset's useful life, which is measured in years. Revenue less costs equals profit.Markup is calculated as follows: markup = 100 * (revenue - cost) / cost.And finally, use revenue = cost + cost * markup / 100 if you need to know the selling price. The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.Original cost = $ 34.15 - $ 0.45/ 100
= 0.33%

A store has a 20% sale on everything. An item originally cost 350 AED. What is the sale price? Show your work of how you calculated the sale price.
Answer:
Step-by-step explanation:
A store has a 20% sale on everything.
So since you are saving 20%, you will only be paying 80% of the original price.
To find the sale price use the following formula:
Sale price = 80% x original price
They told us the original price = 350 AED
This means:
Sale price = 80% x 350
I think it would be easiest to change 80% into a fraction if you don't have a calculator :)
80% = [tex]\frac{80}{100} = \frac{4}{5}[/tex]
This means that the
Sale Price= [tex]\frac{4}{5}[/tex] x 350 = 280 AED
Which of the following is correct about parallel lines?
A. Nonvertical parallel lines will have the same slope and y-intercept.
B. The slope of nonvertical parallel lines will be m and −m.
C. Nonvertical parallel lines will have the same slope but different y-intercepts.
D. The product of the slope of the two lines would be −1.
Answer:
C. Nonvertical parallel lines will have the same slope but different y-intercepts.
Step-by-step explanation:
Parallel lines never intersect, so they must have the same slope. The reason why option A is incorrect is because if they had the same y-intercept, they would be considered the same line directly on top of each other, and parallel lines never touch. :)
Nonvertical parallel lines will have the same slope but different y-intercepts. Then the correct option is C.
What is the equation of a parallel line?When the distance between the lines is constant then the lines are called parallel lines. The lines do not intersect when they are separated from each other. And the slope of the lines is equal.
Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.
The slope of the parallel line will be congruent. And the product of the slopes of the perpendicular lines will be negative 1.
Nonvertical parallel lines will have the same slope but different y-intercepts. Then the correct option is C.

Answer:
Linear
Step-by-step explanation:
The y is increasing constantly by 5 each time. The equation that would represent this is y=5x-7 because when x is 0 y is -7, so that is your y intercept, and the m, or slope, of your graph is 5, because of the constantly increasing y.
The given table is representing linear function. So Option B is correct.
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Given that,
A table
x 0 1 2 3 4 5
y -3 5 13 21 29 37
Lets us first check that data for linear relationship,
Consider a function,
y = mx + c
lets put value (0, -3)
-3 = m0 + c
c = -3
y = mx -3
Now putting second point
5 = mx1 -3
m = 8
y = 8x - 3
If third point satisfies the given condition
then it will be linear function
x = 2 & y = 13
y = 8x -3
13 = 8x2 - 3
13 = 13
hence proved
Thus, the given table represents the linear function.

Thirty-six students at a large university were given a test to measure their intelligence quotient (IQ). A histogram of the IQ test scores is shown below. In each interval, the left endpoint is included in the interval, but not the right endpoint. A histogram titled I Q Scores has I Q score on the x-axis and frequency on the y-axis. 93 to 96, 1; 96 to 99, 3; 99 to 102, 5; 102 to 105, 8; 105 to 108, 2; 108 to 111, 7; 111 to 114, 7; 114 to 117, 2; 117 to 120, 1. In which interval is the median located?
Answer:
102-105
Step-by-step explanation:
Median formula for a group data is expressed as shown;
Median = (N+1)/2 th value/interval
N is the total number of students
From the question N = 36
Median = (36+1)/2
Median = 37/2
Median = 18.5
Therefore we are to cumulate the value of the frequency up till the 18.5th value.
From the table
If we keep cummulating the frequency from the top;
Let's add:
1+3+5+5+8 = 21
Since the 18.5th values falls within the cumulative frequency value (i.e 21), the corresponding interval where we stopped cumulating will be our Median.
From the table, the interval with the frequency of 8 is 102 - 105. Hence the median is located at the interval 102 - 105

102-105

Answer:
The degree of f(x) is even and the leading coefficient is positive. There are 3 real zeros and 2 relative minimum values.
Step-by-step explanation:
We have the graph of f(x).
In general, remember these points:
If the end behavior of the graph is the same, then the function must be an even degree function. If the end behaviors are different, then the function must be an odd degree function.For even-degree functions:
If both end behavior goes towards positive infinity, then the leading coefficient is positive. If both end behavior goes towards negative infinity, then the leading coefficient is negative.And for odd-degree functions:
If the right end-behavior goes towards positive infinity, then the leading coefficient is positive. If the right end-behavior goes towards negative infinity, then the leading coefficient is negative.P.S. Yes, it's a lot. But grasping these concepts will help you greatly in future mathematics!
Anyways, let's go back to our problem. Our graph has the same end behavior, so it must be an even function.
Moreover, both end behavior are approaching positive infinity, so the leading coefficient must be positive.
The real zeros of a function are whenever the graph touches or crosses the x-axis. We see that it happens only three times (this is circled in blue below in the image).
The relative minimum values are whenever the graph reaches its lowest point between an increasing and decreasing (or decreasing and increasing) curve. This happens twice (this is circled in black below in the image).
Note: The black arrows denote whether the graph is increasing or decreasing (down means decreasing, up means increasing).
So, you can see that our minimums will always be between a decreasing and then an increasing curve.
So, our solution is:
The degree of f(x) is even and the leading coefficient is positive. There are 3 real zeros and 2 relative minimum values.
And we're done!
