Write and solve an equation that can be used to find x, in the figure below:
Answers
Answer: x=40
Step-by-step explanation:
so you would add the two angles you already know.
30+63=93
The sum of the angles of a triangle is always 180°. Knowing this, you can do
180-93=87
so you know the third angle is 87°
plug this into the equation: 2x+7
2x+7=87
subtract both sides by 7
2x=80
divide by two
x=40
1. Add the 2 angles you already know.
30 + 63 = 93
2. The sum of all angles in a triangle is always 180°
180 - 93 = 87
3. third angle is 87°
2x + 7 = 87
4. Subtract BOTH sides by 7
2x = 80
5. Divide by 2
X = 40

An image of a rhombus is shown.
a rhombus with a base of 18 centimeters and a height of 15.5 centimeters
What is the area of the rhombus?
16.75 cm2
33.5 cm2
139.5 cm2
279 cm2
Answers
Formula used,
Area of rhombus = Base × height
Substituting the values,
\( \longrightarrow\)Area = 18 × 15.5
\( \longrightarrow\) Area = 279 cm²
Therefore, 279 cm² is the area of the rhombus .
Answer:
D) 279 cm²
Step-by-step explanation:
Area of a rhombus formula:
\(A=bh\)
This formula is also used for squares and rectangles.
So, we can substitute in our values such as:
A=(18)(15.5)
simplify
A=279
Now, add our label and units:
A=279 cm²

Lenor is the manager at a catering company. Each dinner consists of one serving of fish and one serving of vegetables. The fish costs f dollars per serving, and vegetables cost v dollars per serving. Lenor needs to make 75 dinners for Friday and 150 dinners for Saturday.
Answers
Answer:
so... what exactly.. is the question. if you lmk i would be happy to answer it for you. but i cant answer an unasked question
Similarly, The total cost of the fish for Saturday is 150 * f dollars. The total cost of the vegetables for Saturday is 150 * v dollars. So the total cost of the dinners for Saturday is 150f + 150v dollars.
The total cost of the dinners for Friday and Saturday is (75f + 75v) + (150f + 150v) = 225f + 225v dollars.
This equation can be written in the form of C = mx + b, where C is the cost of the dinners, m is the cost per serving (m = f+v) and x is the number of dinners, b is 0 because there is no fixed cost.
It's also important to mention that this equation is only describing the cost of the dinners. If there are any other costs or expenses like delivery or tip, it should be added to the equation.

Find the value of x please :)
Answers
Answer:
32 degrees
Step-by-step explanation:
The sum of all angles in a triangle is 180 degrees.
A right angle (The one marked by a small square on the bottom left) measures 90 degrees.
You're given that the other two angles in the triangle measure 58 and x degrees.
To find x, we'll find the sum of all angles, and equate it to 180.
The sum of all angles = 90 + 58 + x = 148 + x degrees
\(148 + x = 180 \text{ // -148}\\\cancel{148 -148} + x = 180 - 148\\x = 32^{\circ}\)

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

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
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
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.

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.
