During a sale, a clothing store discounts all prices by the same percentage. A pair of jeans is marked down from $45 to $33.75. What is the sale price for a $65 sweater after the same discount is applied?
Answers
Answer:
48.75
Step-by-step explanation:
33.75 is 75% of 45
So price of sweater is 75% of 65, or 25% less which is 48.75

Sai has a garden on the side of his house that will be enclosed with 196 ft. of fencing. The
rectangular plot will be fenced in on all sides except for the side against the house. What
dimensions will maximize the plot of land? What is the maximum area?
PLEASE DO THESE BELOW
-use written and verbal explanination that justifies each step
-Use at least one representation(ex number sentences, diagrams, charts, etc)
Answers
Answer:
49 and 98, with an area of 4802
Step-by-step explanation:
So, let X be one of the sides, and Y be the other
X*Y would be the area of the rectangle since width*length = area, and X is the width and Y is the length
2X+Y would be the perimeter, excluding the wall (since we don't need fencing for the side sticking to the wall)
To find the max area, we can plot our two equations
so, our two equations:
1. 2X+Y=196 (since perimeter)
2. X*Y=area, and we're trying to maximise it
We can re-arrange the first equation to get
3. Y=196-2X
plug our new equation (#3) into the second equation(#2)
to get:
X*(196-2X)=area=196X-[tex]2X^2[/tex]
And now that we have this equation, we can either:
Graph it to see the largest area (the highest point)
Or calculate the max area using calc
We have a quadratic function that goes up, then down as X increases, so we'll try to find the point where the function stops going up, and instead goes down as X increases (image is attached, not to scale). Recall that the first derivative basically tells is the slope of a function/equation at a given X, so when the function is at a slope of 0, we know that the area is at its max point.
Take the first derivative
(196X-2X^2)'=196-2(2X)=196-4X
196-4X is the equation of the slope, so when X = 49, then the slope is 0
This means that one of the side lengths should be 49
To find out which one, we can use trial and error: (there are 2 cases)
1. 49*((196-49)/2)=3601.5
or:
2. 49*(196-2*49)=4802
The second option is correct since the number, or the area is larger.
Side length 1: 49
Side length 2: (196-2*49), or 98
Note: there's definitely another way to do this problem

Answers
Answer: It would be A
Step-by-step explanation:
First: Find Median
18,19,|19|,20,|20,20|,21,|22|,22,26
there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3
Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.
Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.

Use the number line to answer the question.
Answers
Answer:
2.23
Step-by-step explanation:
The reason why this is your answer is that this number is between 2 2/10 and 2 3/10. That means that turned into decimals, this number will be somewhere between 2.2-2.3
Now, we can see that this is 3 units away from 2 2/10 on the number line, which tells us that the decimal is 2.23
So hence, your answer is 2.23

Compare the function represented on the graph and the function modeled by y = 2 3 x. Click to select the TRUE statement(s).
A. The y-intercept of both functions is 0.
B. The slope of both functions is 3 2.
C. The graph's function has a greater rate of change.
D. Point (0, 0) is the point of intersection for the functions.
Answers
A, C, and D.
Explanation:
The y-intercept for the written equation would have to be zero if there is none written in the problem.
They have a different slope and the same y-intercept, so they will intersect on it (which is 0)
The graph’s function has a greater rate of change because it’s slope is 1/2, while the slope for the written equation is 2. (smaller # is a bigger change).
A corner store sells 60-watt bulbs in packs of 4.
Write an equation that shows how the number of bulbs in stock, y, depends on the number of packages, x.
Answers
Answer: y = -4x + 60
Step-by-step explanation:
we can use a simple linear equation to write this problem:
y = mx + b
The slope is given to be the number of bulbs in each pack, which is 4.
now we have: y = 4x +b
The value of b is the y intercept, or the starting value, 60. From this value, 4x can be subtracted to show our remaining bulbs in stock:
y = 60 - 4x
Writing this in the form y = mx+b gives us the equation:
y = -4x + 60
Answer:
y = 4x
Step-by-step explanation:
A corner store sells 60-watt bulbs in pack of 4.
x = number of packs
y = number of bulbs
y = 4x
Check your answer using the problem:
60 = 4x
/4 /4
12 = x
This means that there are 12 bulbs in each pack.
Hope this helps!

You resize a picture so that the radius of the midday Sun appears four times larger. How much larger does the circumference of the Sun appear?
The circumference appears (BLANK) times larger.
Answers
Answer:
The circumference appears four times larger.
Step-by-step explanation:
C=2πr
So if we are multiplying the radius (r) by 4 then that would most definitely increase the outcome (circumference) by 4
here's why:
C=2πr
C=2π(4r)
C=8πr
So,
8πr/2πr = 8/2 = 4
