If Earl Miller, a customer of J. Crew, will pay $400 for a new jacket. J. Crew has a 60% markup on selling price. The most that J. Crew can pay for this jacket is $160.

Given parameters:

Cost of new jacket = $400

Markup = 60%

Now let find the amount that was paid for the jacket using this formula

Amount = Cost of new jacket × ( 1- markup)

Let plug in the formula

Amount = $400 × ( 1 - .60 )

Amount = $400 × .40

Amount = $160

Therefore we can conclude that the amount of $160 was paid the most.

Answer:

• The dimensions of the garden are 90 feet by 60 feet.

• The length of the garden is 90 feet.

Explanation:

Let the length of the garden = l

The width is exactly two-thirds of the length, Width = (2/3)l

If 300 feet of antique picket fencing are to be used to enclose the garden, this means that the perimeter of the proposed garden is 300 feet.

Next, solve the equation for the length, l:

The length of the garden is 90 feet.

Next, we determine the width.

The dimensions of the garden are 90 feet by 60 feet.

Answer:

100 cans

Explanation:

• The total number of canned food items collected = 3,195

• The number of classrooms that participated = 28

To estimate the number of items each classroom donated, divide 3195 by 28.

Note: Round to a whole number since the number of cans cannot be a decimal.

Each class donated about 100 cans.

(a) Graphing the equation

(i) let x = 0 ; then

y = -0.05 (0) +16

∴ y = 16

Point 1 = ( 0;16 )

(ii) let y = 0 , then

0 = -0.05x +16

0.05x = 16

x = 16 /0.05

∴ x = (320 )

point 2 = ( 320; 0 )

The graph of the line ( y = -0.05x+16) will then be as follows :

{To interpret means to explain in details or translate in writing the meaning of the values of x and y . }

• x represents the number of miles travelled

• y represents gasoline used i gallons

Interpretation:

• when ,x is 0 miles, , the ,gasoline ,is sitting at, 16 gallons.,( this might be the initial stage of travelling)

• however, when the, person has travelled 320 miles,, all gasoline is ,completly used up and sits at 0 gallons, .( this might be the end stage of travelling)

ANSWER and EXPLANATION

We have letter W on the graph.

The cordinates of its vertices are:

(0, 4), (1, 0), (2, 2), (3, 0), (4, 4)

Now, on a cartesian plane, (x - y plane), we have 4 quadrants. The letter is on the first quadrant.

Because it rotates 180 degrees around the origin, it means that it mmoves by 2 quadrants:

So, it moves from quadrant 1 to quadrant 4.

The new cordinates become:

(0, -4), (-1, 0), (-2, -2), (-3, 0), (-4, -4)

Then it is translated 4 units up, so we add 4 units to each of the y values (Remember that cordinates are written as (x, y)):

(0, 0), (-1, 4), (-2, 2), (-3, 4), (-4, 0)

Now, plot those:

a) It forms the letter M.

b) For one shape to be congruent to another, it means that they have the same size. So, yes, the M is congruent to the W.

we can see that angles 2 and 4 are vertically opposite and they are also equal.

Recall that angles 1 and 3 are also vertically opposite and they are also equal.

Therefore, we can see that:

Divide both sides by 2, we have that:

CONCLUSION:

Explanation

Given the following expression

For topic (1), we have the following question:

Which of the following is a function: y=x² or x=y²?

Identify domain and range of each equation.

We can identify a given relation if it is a function or not by identifying the number of possible values of y.

The equations below are both relations.

However, only one of them is a function.

For the first equation, note that for each value of x, there is only one value of y. Some of the points on the equation are as follows.

Thus, the equation passes through the following points.

Notice that no value of x is repeated. Therefore, the given relation is a function.

We can also determine it using graphs. The image below is the graph of the first equation.

If we test it using the vertical line test, no vertical line can pass through the graph twice. Therefore, it shows that the equation is a function.

On the otherhand, the other equation is not a function. This is because when we substitute -2 and 2 to the value of y, we will have the same value of x, which is equal to 4.

Since there are two values of y for only one value of x, the equation must not be a function.

To illustrate this using its graph, we can notice that the vertical line below passes through two points on the graph when x=4.

Therefore, the second equation is not a function.

As for the domain and range, we can obtain it from both graphs.

The domain the set of all possible values of x. Thus, for the first equation, since it extends indefinitely to the left and right, the domain must be from negative infinity to positive infinity.

On the otherhand, since the second equation extends indefinitely to the right from 0, the domain must be from 0 to positive infinity, inclusive.

As for the range, it is the set of all possible values of y.

Thus, for the first equation, since the graph extends indefinitely upwards from 0, the range must be from 0 to positive infinity, inclusive.

On the otherhand, the graph of the second equation extends indefinitely upwards and downwards. Thus, its range must be from negative infinity to positive infinity.

To summarize, here are the questions and the answers for each question.

Which of the following is a function: y=x² or x=y²?

Answer: y=x²

Identify domain and range of each equation.

Answer:

For y=x²:

For x=y²:

The acute triangles are those whose all 3 angles have a measure less than 90 degrees.

We need to follow the next image:

Let us check each triangle.

Triangle A:

It has a right angle, hence, it can not be an acute triangle.

Triangle B:

All three sides are less than 90 degrees. Hence, it is an acute triangle

Triangle C:

It has an angle with a measure of more than 90 degrees. Hence, it can not be an acute triangle.

Triangle D

All three sides are less than 90 degrees. Hence, it is an acute triangle.

Triangle E

It has a side with a measure of more than 90 degrees. Hence, it can not be an acute triangle.

Triangle F

It has a right angle, hence, it can not be an acute triangle.

Hence, the correct answer is H. B and D

We will have the following:

So, the value of x is 8.

when evalueatong the expression 13/15,

13 serves as the dividend and

15 is the divisor

Divisor is always placed outside the division sign and the dividend inside.

According to the option, you can see that 15 which is the divisor is placed outside and 13 is placed inside.

check the diagram below:

Option A is the correct answer in this case

3. In one linear function, when you subtract each y-coordinate from the x-coordinate, the difference is 3. If the x-coordinate is not greater than 10 and the y-coordinate is a positive whole number, how many ordered pairs are there?

Solution

Here are the conditions

x- y= 3

x <10

y >0

And then we have these as possible answers:

4-1 =3

5-2= 3

6-3=3

7-4=3

8-5=3

9-6=3

Then the total possible pairs are: 6

The starting point of the elevator car = 27 feet above the ground

The endpoint point of the elevator car = 102 feet above the ground

The total distance traveled by the elevator car = 102 feet - 27 feet

The total distance traveled by the elevator car = 75 feet

Time taken by the elevator car to rise 4.2 feet = 1 second

Time taken by the elevator car to rise 75 feet = 75/4.2 seconds

Time taken by the elevator car to rise 75 feet = 17.86 seconds

Therefore, it takes the car 17.86 seconds to reach a height of 102 feet above the ground

Let the number be a

6a x 5a + 8

To answer this question, we need to remember two theorems of parallelograms:

1. If a quadrilateral is a parallelogram, the two sets of its opposite angles are congruent:

2. The consecutive angles of parallelograms are supplementary (they sum 180 degrees):

Then, with this information, we have that:

And also, we have that the diagonal forms two congruent triangles, and the sum of internal angles of a triangle is equal to 180, then, we have:

Then, we have:

Then, using that the consecutive angles of parallelograms are supplementary (they sum 180 degrees), we have:

Thus, we have that the measure for angle a is:

In summary, we have that (all the measures in degrees):

m< a = 26

m< b = 57

m< c = 97

The confidence interval depends on the margin of error. When finding the margin of error, the z score corresponding to the 95% confidence level would be multiplied by the square root of the product of the estimated proportion of success and failure divided by the sample size. The greater the sample size, the smaller thie value that would be gotten from this operation. The smaller the sample size, the greater the value that would be gotten from this operation. A greater value would give a bigger margin of error. Thus, the confidence interval would be wider. Hence, the correct option for the sampe size is

A. 40
