Determine the value of x in the triangle shown. answers : 180° 135° 90° 45°
Answers
Answer:
x = 135
Step-by-step explanation:
45 and x from a straight line so they sum to 180 degrees
45+x = 180
Subtract 45 from each side
45+x-45 = 180-45
x = 135
Answer:
x = 135°
Step-by-step explanation:
The two angles form a 180° (straight) line. They are supplementary angles.
180° - 45° = 135°

Answers
Answer: 858.55 in
Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.
Answer:
858.55
Step-by-step explanation:
Area of triangle = 1/2BH
1/2(22.3*15.4) = 171.71
Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.
171.1(5) = 858.55

When given a system of equations in slope-intercept form, is graphing or substitution the most efficient method to solve? Explain.
Choose the best answer below.
A.
Substitution is the only method that should be used if the answer involves integer values. If the answer involves values that are not integers, graphing would be more efficient because an exact answer can be obtained. It is easier to read graphs when the point of intersection does not occur at integer values.
B.
Graphing is the only method that would be appropriate to use here because it is not possible to use the substitution method if both equations are in slope-intercept form.
C.
Substitution is the only method that would be appropriate to use here because it is not possible to use the graphing method if both equations are in slope-intercept form.
D.
Graphing and substitution are appropriate to use if the answer involves integer values. If the answer involves values that are not integers, substitution would be more efficient because an exact answer can be obtained. It can be difficult to read graphs if the intersection point does not have integer values so this would be an inefficient method to solve with.

What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, a system of equations in slope-intercept form y₁ = m₁x₁ + b₁ and
y₂ = m₂x₂ + b₂.
We can use both substitution and graphing depending on the numerical values of the variables.
If the solution involves integer numbers, graphing and substitution are the proper methods to utilize. Substitution would be more effective since an accurate solution may be reached if the solution involves values that are not integers. If the intersection point doesn't have integer values, it can be challenging to understand graphs, so using this approach to solve would be ineffective.

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
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.

Answer: 198
Step-by-step explanation:
Firstly, you must find the nth term.
the sequence is: -9, 0, 9, 18, 27, ...
find the difference between each term. in this sequence, the difference is 9, so it is 9n
then you must find the difference between the sequence 9n and this sequence. 9n is:
9, 18, 27, 36, 45, ...
now find the difference between 9n and our sequence.
adjustment = -18
so the nth term is 9n - 18
now you need to substitute 24, as that is the term you would like to find out, in place of n.
so, our n term looks like this: 9(24)-18
9 x 24 = 216
216 - 18 = 198
hence, the answer is 198.
hope this helps.

Answer:
c = 29
Step-by-step explanation:
Alright, So from the numbers, we know each side is 7
So overall area is 49
And each triangle is 5(5 x 2/2)
And multiply that by 4 to get 20
49 - 20 is 29
Answer: the length of c is √29
Step-by-step explanation:
The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."
The formula looks like c² = a² + b²
To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.
Square each of those numbers, then add them together.
2² means 2×2=4 and 5² is 5×5=25 4+25 = 29
Now we go into reverse to get the value of c. We have c²=29
So we take the square root of 29 c=√29
That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)
√29 is about 5.385164807.... and it keeps going. Just round it off!
(Some math teachers are fine with leaving the irrational roots as √something)
Apparently, the green answer box for this question needs √29
But it helps if you can associate some nearly rational value to make sense of it.
But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.

Answers
Answer: 4
Step-by-step explanation:
Divide the sides of triangle D' by their corresponding sides on triangle D (like 32 divided by 8 and 40 divided by 10). The answer every time is 4 which means the scale factor is 4.
Answer:
The answer is 4
Step-by-step explanation:
In triangle D the top side length is 8 and in triangle D' the top side length is 32. 32 is 4 times 8, and therefore D' was factored by a scale of 4 from D.
This can be done with each side:
8x=32 --> x=4 therefore the scale factor is 4
6x=24 --> x=4 therefore the scale factor is 4
10x=40 --> x=4 therefore the scale factor is 4
