Darlene wants to buy a sweater that originally cost $48. It is on sale for 35% off. Sales tax is 8%. What is the final price of the sweater with tax?

$28.70
$47.73
$33.70
$56.16

Answers

Answer:

$33.70

Step-by-step explanation:

The sweater costs $48. It is on sale for 35% off. The sales tax is 8%. We want to know the final price.

We know that 35% is the same as 0.35. We are going to multiply $48 by 0.35. This results in $16.80. The 35% is 35% off, so we are going to subtract $16.80 from the $48. This gives us $31.20. Now, we still have the 8% sales tax. 8% is the same as 0.08. We will multiply this by $31.20. This gives us $2.496, which we can round to $2.50. That is how much the sales tax is. It will be added to the price of the sweater. The result is $33.70.

Answer: I'd say you can eliminate option 56.16 and maybe go with 33.70

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.

Answers

Answer:

Perimeter is 12mm, height is $2\sqrt3$mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem ($a^2+b^2=c^2$) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Which inequalities would have an open circle when graphed? Check all that apply.
t Less-than-or-equal-to 25
-2.5 Less-than-or-equal-to m
x > 5.4
One-half less-than x
x > 0

Answers

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:

x > 5.4

One-half less-than x

x > 0

All of the options that are just LESS THAN are open circled

if an inequality states less than OR equal to that means the circle will be closed when graphed

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

Which proportion would you set up to change 5 pounds to ounces?
A: 1/16 = 5/x
B: 1/8=5/x
C: 1/8=x/5
D: 1/16=x/5

Answers

Answer:

A: 1/16 = 5/x

Step-by-step explanation:

1 pound is 16 ounces

5 pounds is 80 ounces

let 5 pounds be x

the equation should be x = 80

A: 1/16 = 5/x

x=80

B: 1/8=5/x

x=40

C: 1/8=x/5

$x=\frac{5}{8}$

D: 1/16=x/5

$x=\frac{5}{16}$

We know 1lbs=16oz

Hence

1oz=1/16

The proportion is

1/16=5/x

Option A

solve for x.

x=16(5)x=80oz

0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

$Triangle NGM is reflected across the x-axis, and is dilated by a factor of [tex]2 \frac{1}{2} [/tex]what$

Answers

The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).

Scale factor = $2\frac{1}{2}$

= 2.5

The reflection of point (x, y) across the x-axis is (x, -y).

Here, N(-4, 6)→(-4, -6)

M(-6, 2)→(-6, -2)

G(-2, 4)→(-2, -4)

Now, with scale factor 2.5, we get

(-4, -6)→2.5(-4, -6)→N'(-10, -15)

(-6, -2)→2.5(-6, -2)→M'(-15, -5)

(-2, -4)→2.5(-2, -4)→G'(-5, -10)

After ten years of being a wizard after graduating from Hogwarts, Harry Potter yearned for a real persons job, and got one delivering packages to UPS customers. Although Harry was great at driving broomsticks, it turns out he is not a very good driver of vans. One day you are driving down the street in your neighborhood and you collide with the van driven by Harry when he didnt stop at a stop sign. You are injured. The van Harry is driving is painted brown (as UPS vans are), and also contains removable magnetic signs displaying the UPS name and logo. When he gets out of the van at the accident scene, Harry is wearing a UPS uniform. The van is not owned by UPS, but by Harry himself. UPSs agreement with Harry is that he is authorized to service UPS customers in your neighborhood. The agreement is memorialized in a contract that identifies Harry as an "independent contractor" and provides that "the manner and means by which Contractor performs the services shall be at Contractor's sole discretion and control and are Contractor's sole responsibility." The agreement gives either party the power to terminate in the event of the other party's breach. The agreement also recites a detailed list of procedures that Harry must follow in processing, picking up, and delivering packages and contains a provision under which Harry is required to indemnify UPS in the event Harry loses or damages packages bound for UPS's customers. Harry is contractually required to "wear a UPS uniform," and is required to submit to unannounced operational inspections and audits at UPS's sole discretion. Harry is also required to maintain the van in good working order, load and unload the van in strict accordance with specifications established by UPS, and always prominently maintain the UPS magnetic labels on the three sides of the van when making deliveries for UPS. Harrys van also contains a tracking device so that UPS can monitor and review the logistics of Harrys deliveries, and Harry can turn the tracking device off when he is not delivering for UPS. Finally, Harry is free to deliver the UPS packages at any time that is convenient for him during assigned delivery days, and he is free to use the van for other purposes when not delivering packages to UPS customers.
