To calculate the sale price of the sweatshirt, multiply the original price by the discount rate to get the discount amount and subtract from the original price. The sweatshirt is now priced at $24.

We can find the amount discounted by multiplying the original price of the sweatshirt by the discount rate. So, we calculate 60% of $60. First distinguish that 60% is the same as 0.60 in decimal form. Therefore, we multiply $60 by 0.60 (60%) to get $36. This is the amount that is discounted from the original price. To find the new price after discount, subtract this amount from the original price. So, $60 - $36 equals $24. Therefore, the sweatshirt on sale is now priced at $24.

Each of the 4 payments made by Mr. Wilson will be $72.10.

How much will each payment be?

From the question, we have the following parameters that can be used in our computation:

Amount owed = $288.40

Number of payments = 4

To calculate the amount of each payment, we can divide the total amount owed by the number of payments:

Amount per payment = Total amount owed / Number of payments

Substitute the known values into the equation

Amount per payment = $288.40 / 4 =

Amount per payment = $72.10

Hence, each payment will be $72.10.

To determine the number of scoops of corn needed to feed different numbers of deer, we can use proportional reasoning. However, since the table mentioned in the question is missing, we can't find the exact values.

To determine the number of scoops of corn needed to feed a certain number of deer, we can use the information given in the table. Let's analyze the information provided:

Unfortunately, the table mentioned in the question is missing, so we can't use it to find the exact number of scoops needed. However, if we assume that the ratio of scoops to deer is consistent, we can use proportional reasoning to find the missing values. For example, if it takes 2 scoops to feed 5 deer, then 4 scoops will be needed to feed 10 deer.

Answer: Divide the room into two figures (a rectangle and a trapezoid), then find the area of both figures and add them in order to calculate the area of the dining room.

Step-by-step explanation:

Divide the room into two figures: a rectangle and a trapezoid (as you can observe in the picture attached).

You need to find the area of the trapezoid and the area of the rectangle and then add them. This sum will be the area of the dining room.

First, you need to remember that:

1. The area of a rectangle can be calculated with this formula:

[tex]A_r=lw[/tex]

Where "l" is the lenght and "w" is the width of the rectangle.

2. The following formula is used to calculate the area of a trapezoid:

[tex]A_t=h(\frac{B+b}{2} )[/tex]

Where "B" and "b" are the bases of the trapezoid and "h" is the height of the trapezoid.

Therefore, the area of the dining room will be:

.[tex]A_{room}=A_r+A_t\\\\A_{room}=lw+h(\frac{B+b}{2} )[/tex]

Answer:

Break the figure into two rectangles and two triangles. Find the area of each using the formulas A=bh and A=1/2bh. The sum of the areas is the area of the dining room.

The graph in the attached figure

Step-by-step explanation:

we have

[tex]f(x)=(x-3)^2+5[/tex]

This is a vertical parabola open upward (the leading coefficient is positive)

The vertex represent a minimum

The vertex is the point (3,5)

The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

so

[tex]x=3[/tex] ---> axis of symmetry

Find the y-intercept (value of f(x) when the value of x is equal to zero)

For x=0

[tex]f(x)=(0-3)^2+5=14[/tex]

The y-intercept is the point (0,14)

Find the x-intercept (values of x when the value of f(x) is equal to zero)

For y=0

[tex]0=(x-3)^2+5[/tex]

[tex](x-3)^2=-5[/tex] ---> has no real solutions

The function has no x-intercepts (The roots of the quadratic equation are complex numbers)

therefore

Final answer:

Laura earns $18 per hour, and for 8 hours of work, she would make $144.

Explanation:

The question asks us to determine how much Laura would make for 8 hours of work, given that she made $324 for 18 hours of work. To find the hourly rate, we divide the total amount earned by the total hours worked. Then we multiply the hourly rate by the number of hours we want to find the earnings for.

To calculate Laura's hourly rate: $324 / 18 hours = $18 per hour.

Now, we can find out Laura's earnings for 8 hours: $18 per hour * 8 hours = $144.

Therefore, Laura would make $144 for 8 hours of work at the same rate.

Answer:

x = 12

Step-by-step explanation:

Pythagoras' Theorem

[tex]a^{2} = b^{2} + c^{2}[/tex]

a = 13

b = 5

c = x

[tex]13^{2} = 5^{2} + x^{2}\\169 = 25 + x^{2}\\169 - 25 = x^{2}\\144 = x^{2}\\12 = x[/tex]

After applying the Pythagorean theorem on the given right-angled triangle the value of x we get 12.

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

The Pythagoras theorem for a right-angled triangle:

(Hypotenuse)²= (Perpendicular)² + (Base)²

For the given triangle:

The hypotenuse 'MC' = 13

The perpendicular 'MN' = 5

Base 'NC' = x

Substituting these values into the Pythagorean theorem:

(13)²= (5)² + (x)²

Simplifying the square,

169 = 25 + x²

Subtracting 25 we get,

x² = 144

Take square root on both sides,

x = 12

Hence,

The value of x is 12.

Earnings of Chris that week = US$ 712.65

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Chris' salary = US$ 6 per hour + 0.9% commission (0.009)

A week Chris worked 32 hours and sold 2 cars priced $ 26,700 and $ 31,150

2. How much did he make that week?

Earnings of Chris that week = (32 * 6) + (26,700 * 0.009) + (31,150 * 0.0009)

Earnings of Chris that week = 192 + 240.30 + 280.35

Earnings of Chris that week = US$ 712.65

Step-by-step explanation:

The time spent for reading is 31.3 minutes

Solution:

You read 9.75 pages in your science book and 24.5 pages of a play for English class

Therefore,

Number of pages read in science = 9.75

Number of pages read in play = 24.5

Also given that,

Time taken to read each page of science = 1.2 minutes

Time taken to read each page of play = 0.8 minute

To find: Time spent for reading

Time spent for reading = Number of pages read in science x Time taken to read each page of science + Number of pages read in play x Time taken to read each page of play

[tex]Time\ spent\ for\ reading = (9.75 \times 1.2) + (24.5 \times 0.8)\\\\Time\ spent\ for\ reading = 11.7 + 19.6\\\\Time\ spent\ for\ reading = 31.3[/tex]

Thus time spent for reading is 31.3 minutes

The equation that represents a line passing through (-2, 4) and has a slope of 2/5 is Oy+4 = (x-2).

The equation that represents a line passing through (-2, 4) and has a slope of 2/5 is option B:

Oy+4 = (x-2)

To understand why this equation represents the line, we can use the slope-intercept form, y = mx + b, where 'm' is the slope and 'b' is the y-intercept. The given slope is 2/5, so the equation becomes y = (2/5)x + b. Plugging in the coordinates of the point (-2, 4), we can solve for 'b' and find that it is 4. Therefore, the equation representing the line is y = (2/5)x + 4.

Answer:

Answer C

Step-by-step explanation:

The probability that a randomly selected dog is female, given it is a Chihuahua, is 3/11. This is calculated by dividing the number of female Chihuahuas (3) by the total number of Chihuahuas (11) in the store.

Probability of Selecting a Female Chihuahua

First, let's determine the total number of Chihuahuas in the store. Since the store has 25 dogs and 14 of them are not Chihuahuas, we subtract 14 from 25 to get the number of Chihuahuas:

25 - 14 = 11

There are 11 Chihuahuas in the store. We are given that there are 3 female Chihuahuas. Therefore, the probability that a randomly selected dog is a female Chihuahua is the number of female Chihuahuas divided by the total number of Chihuahuas:

Probability = Number of Female Chihuahuas / Total Number of Chihuahuas = 3 / 11

This calculation gives us the probability of 3/11 that a dog selected at random is female, given it is a Chihuahua.
