Barry is shopping for a new sweater that originally cost $50.00. The department store has all items marked down by 20%. He also has a coupon for an additional 10% off all purchases.
Barry
Since all items are marked down by 20%, and I have an additional 10% off, that means
I get a 30% discount.
The cost of the sweater is $50.00 – $15.00 = $35.00.
Describe Barry’s mistake. Then calculate how much Barry will pay for the sweater.
Answers
9514 1404 393
Answer:
mistake: the base for the additional discount is not the original price$36Step-by-step explanation:
The marked-down price is ...
$50 × (1 - 20%) = $50 × 0.80 = $40
Barry gets a 10% discount on that price, so his discount is ...
$40 × 0.10 = $4
Barry pays $40 -4 = $36.
__
Barry would be correct if the "additional 10% off" were based on the original price, but it isn't. It applies to the already-discounted price.

Answer:

The domain of the function x≥ 5.
What is Domain and Range?The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f(x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.
The domain takes all of the potential input values from the set of real numbers, while the range takes all of the function's output values.
We have the function y = √(x- 5)
The domain is the x values operate, often known as the horizontal axis.
The Range is y values on the vertical axis.
As, the radical never gives Negative Value.
So, x- 5 ≥ 0
and, x≥5
Thus, the domain is x≥ 5.

Robert Downey Jr.'s costume rental shop charges $8 a day to rent a costume. Chris Evans' costume rental shop charges $6 a day and a $160 fee to rent a costume. For how many days would it be the same cost to rent a costume from either shop?
need the equation with variables on both sides
Answers
Answer:
80 days
Step-by-step explanation:
Start off by making the two equations.
t = total cost
d = days
Robert Downey Jr.'s equation would be:
t = 8d
Chris Evans' equation would be:
t = 6d + 160
Now, set them equal to each other:
8d = 6d + 160
Then, solve for d:
8d = 6d + 160
Subtract 6d from both sides:
2d = 160
Divide both sides by 2:
d = 80 days

This is your lucky day. You have just won a $20,000 prize. You are setting aside $8,000 for taxes and partying expenses, but you have decided to invest the other $12,000. Upon hearing this news, two different friends have offered you an opportunity to become a partner in two different entrepreneurial ventures, one planned by each friend. In both cases, this investment would involve expending some of your time next summer as well as putting up cash. Becoming a full partner in the first friend’s venture would require an investment of $10,000 and 400 hours, and your estimated profit (ignoring the value of your time) would be $9,000. The corresponding figures for the second friend’s venture are $8,000 and 500 hours, with an estimated profit to you of $9,000. However, both friends are flexible and would allow you to come in at any fraction of a full partnership you would like. If you choose a fraction of a full partnership, all the above figures given for a full partnership (money investment, time investment, and your profit) would be multiplied by this same fraction.
Because you were looking for an interesting summer job anyway (maximum of 600 hours), you have decided to participate in one or both friends’ ventures in whichever combination would maximize your total estimated profit. You now need to solve the problem of finding the best combination.

Help please numbers 15-16
Answers
Answer:
for 15 the answer is 61 and
16 the answer is 82
Step-by-step explanation:
First you need to know that these are vertically opposite angles and that the vertical opposite angles are always the same.
therefore in qn 15.
- the 125 degrees angle is vertically opposite to the 64 + x angle therefore we make an equation
64 + x = 125 (then minus 64 on both sides)
(64 - 64)+ x = 125 - 64
x = 125 - 64
x = 61
the same goes for qn 16.
85 + x = 167 (then minus 85 in both sides)
85 - 85 + x = 167 - 85
x = 167 - 85
x = 82

A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months.

Complete the equation for the relationship between the thickness and number of weeks. y=
Answers
Given:
Initial ice sheet's thickness = 2 meter
After 3 weeks, the ice sheet's thickness = 1.25 meters
To find:
The equation for the relationship between the thickness and number of weeks.
Solution:
Let y represent the ice sheet's thickness (in meters) after x weeks.
Initial ice sheet's thickness = 2 meter
It means, the equation of relation must be satisfy by the point (0,2).
After 3 weeks, the ice sheet's thickness = 1.25 meters
It means, the equation of relation must be satisfy by the point (3,1.25).
If a linear function passes through two points, then the equation is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-2=\dfrac{1.25-2}{3-0}(x-0)[/tex]
[tex]y-2=\dfrac{-0.75}{3}x[/tex]
[tex]y-2=-0.25x[/tex]
Add 2 on both sides.
[tex]y=-0.25x+2[/tex]
Therefore, the required equation for the given relation is [tex]y=-0.25x+2[/tex].

A circle has a radius of 12 cm. If the area is multiplied by 25, what happens to the radius?
Answers
Answer:
The radius is multiplied by 5.
Step-by-step explanation:
The radius of the circle is multiplied by 5 times the radius of the old circle
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the radius of the old circle be r₁
Now , the area of the old circle A₁ = π( r₁ )²
And , let the radius of the new circle be r₂
where area of new circle = 5 x area of old circle
And , A₂ = 25A₁ = π( r₂ )²
On simplifying , we get
25A₁ / A₁ = π( r₂ )² / π( r₁ )²
( r₂ )² = 25( r₁ )²
On further simplification , we get
Taking square roots on both sides of the equation , we get
r₂ = 5r₁
Therefore , the value of r₂ = 5r₁
Hence , the new radius is 5 times the old radius of circle

how do i do a dialation
Answers
Answer:
A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller).
Step-by-step explanation:
Dilations can also reduce the size of shape. The picture below demonstrations a dilation of 12 Any time that the scale factor is a fraction, the image will get smaller.
It's always easier to understand a concept by looking at specific examples with pictures, so I suggest looking at the dilation examples below first...before you try to internalize the steps listed below and that explain the general formula for dilating a point with coordinates of (2, 4) by a scale factor of 12.

Figure WXYZ is rotated 90° clockwise around the
origin to form figure W'X'Y'Z'.
Answers
The coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).
The coordinates of the quadrilateral WXYZ is W(-4, 5), X(-1, 4), Y(-6, 1) and Z(-8, 3).
We need to find the coordinates of the figure W'X'Y'Z', in which figure WXYZ is rotated 90° clockwise.
What is the rotation of the figure 90° clockwise?To rotate the figure 90° clockwise about a point, every point (x,y) will rotate to (y, -x). Let's understand the rotation of 90° clockwise about a point visually. So, each point has to be rotated and new coordinates have to be found.
Now,
W (-4, 5)→W' (5, 4)
X (-1, 4)→X' (4, 1)
Y (-6, 1)→Y' (1, 6)
Z (-8, 3)→Z' (3, 8)
Therefore, the coordinates of the figure W'X'Y'Z' are W' (5, 4), X' (4, 1), Y' (1, 6) and Z' (3, 8).
