If Joe wants to purchase a ball that costs $15 and has a 15% off discount, how much does Joe have to pay
Please explain with proof

Answers

You will pay $12.75
(The easiest way of calculating discount is, in this case, to multiply the normal price $15 by 15 then divide it by one hundred. So, the discount is equal to $2.25. To calculate the sales price, simply deduct the discount of $2.25 from the original price $15 then get $12.75 as the sales price.)

What is the measure of angle 2 if angle 1 is (5x - 2) and angle 2 is (2x)?

Answers

Answer:

52 degrees

Step-by-step explanation:

We're given:

Angle 1 = 5x-2Angle 2 = 2x

The sum of the two angles is 180 degrees, because they construct a straight edge together. A straight line has an angle measure of 180 degrees.

Knowing this, we can form the following equation and solve for x:

$5x-2+2x=180\\7x-2=180\\7x=182\\x=26$

Therefore, x is 26. Find 2x to find the measure of Angle 2:

$2*26=52$

Therefore, Angle 2 has a measure of 52 degrees.

Answer:

Step-by-step explanation:

Angle 1 and angle 2 are on a straight line so their measure add up to 180 and they are supplementary

m<1 + m<2 = 180

5x - 2 + 2x = 180 add like terms

7x - 2 = 180 add 2 to both sides

7x = 182 divide both sides by 7

x = 26

To find the measure of angle 2 replace x with the value we found

m<2 = 2x

2*26 = 52

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.

Mimi bought some fabric for a sewing project. The fabric cost $15.40 per meter. She bought 250 centimeters of fabric.

How much did Mimi pay for the fabric?

Answers

Answer:

$38.50

Step-by-step explanation:

so there are a hundred centimetres in a meter so u have to divide the 250 by 100

250 / 100 = 2.5 meters

and its 15.40 for 1 meter and she bought 2.5 so multiply those

15.40 * 2.5 = 38.50

she paid $38.50 for 2.5 meters of fabric

Answer:

$38.50

Step-by-step explanation:

There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!

What is the length of the diagonal, d, of the rectangular prism shown below?
Round your answer to the nearest tenth.

Answers

Answer:

d = 9.6 (1dp)

Step-by-step explanation:

Based on the picture below

Using Pythagoras

$a^{2} + b^{2} = c^{2} \\8^{2} + 2^{2} = x^{2} \\64 + 4 = x^{2} \\68 = x^{2} \\x = \sqrt{68}\\$

Using Pythagoras

$a^{2} + b^{2} = c^{2} \\5^{2} + (\sqrt{68})^{2} = d^{2}\\25 + 68 = d^{2}\\93 = d^{2}\\d = \sqrt{93}\\d = 9.64365...\\d = 9.6 (1dp)$

The length of the diagonal, d, of the rectangular prism is 9.6 .

What is rectangular prism?

A rectangular prism is a polyhedron with two congruent and parallel bases. It is also called a cuboid. A rectangular prism has six faces, and all the faces are in a rectangle shape and have twelve edges. Because of its cross-section along the length, it is said to be a prism.

What is the length of diagonal of rectangular prism ?

The formula for the length of the diagonal of a right rectangular prism is :

$\sqrt{l^{2} +b^{2} +h^{2} }$

where l is the length, b is the breadth and h is the height of a right rectangular prism.

According to the question

Length of rectangular prism = 5

Breath of rectangular prism = 8

Height of rectangular prism = 2

Now,

The diagonal of rectangular prism = d

By using the formula of the length of the diagonal of a rectangular prism is :

$\sqrt{l^{2} +b^{2} +h^{2} }$

Substituting the value in formula

$\sqrt{l^{2} +b^{2} +h^{2} }$ = d

$\sqrt{5^{2} +8^{2} +2^{2} }$ = d

$\sqrt{25 +64 +4 }$ = d

$\sqrt{93 }$ = d

Therefore,

d = 9.6

Hence, the length of the diagonal, d, of the rectangular prism is 9.6 .

A new movie is being released and it is expected to be a blockbuster. Use the information below to predict how much money the movie will make in ticket prices over the opening weekend.
• The average movie ticket price in the country is $9
• There are approximately 1.2×10* movie screens that will be playing the movie in the country.
• For each screen, there is an average of 250 seats, and it is expected that each showing will be sold out.
• There are 8 showings per screen over the opening weekend.

Answers

Answer:

$3.456 billion

Step-by-step explanation:

To predict how much money the movie will make in ticket prices over the opening weekend, we can use the following information:

The average movie ticket price is $9

There are approximately 1.2x10^6 movie screens that will be playing the movie

For each screen, there are 250 seats and it is expected that each showing will be sold out

There are 8 showings per screen over the opening weekend

To calculate the total amount of money the movie will make in ticket prices over the opening weekend, we can use the following formula:

total revenue = (average ticket price) x (number of screens) x (number of seats per screen) x (number of showings per screen) x (number of days)

total revenue = $9 x 1.2x10^6 x 250 x 8 x 3

total revenue = $3,456,000,000

Therefore, the movie is expected to make $3.456 billion in ticket prices over the opening weekend.

D would also work as 41-16=25 and 9+16 is also 25, meaning boxes C and D would be equal. Boxes A and B would also be equal as 32-7=25 and 18+7=25.

A would NOT work as 41-21 is equal to 20, meaning box C would be lacking 5 blocks. C would NOT work as whilst A and B would be equal, C and D would not be. E would also NOT work as nothing would be equal at all.

B: Remove all blocks and make four equal piles of 25, then put each pile in one of the boxes and D: Remove 7 blocks from box 1 and place them in box 2 and remove 16 block from box 3 and place them in box 4

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.
