Answer:
45°
Step-by-step explanation:
Given a polygon with an interior angle of 135°, you want to know the measure of the corresponding exterior angle.
Exterior angleAt any given vertex of a polygon, the interior and exterior angles are supplementary:
exterior angle = 180° - interior angle
exterior angle = 180° -135°
exterior angle = 45°
Answer: The sum of the interior angles of a regular polygon can be found using the formula:
(n-2)180°, where n is the number of sides of the polygon.
Let's call the number of sides of the polygon "s".
We know that one of the interior angles is 135°, so we can set up an equation using the formula for the sum of the interior angles:
s * 135° = (s-2)180°
Expanding the right side of the equation:
s * 135° = (s-2) * 180°
s * 135° = s * 180° - 360°
Solving for s:
135° = 180° - 360°/s
135° = 180° - 2 * 180°/s
135° = 180° - 2 * (180°/s)
180° - 135° = 2 * (180°/s)
45° = (180°/s)
So, s = 180° / 45° = 4 sides.
The size of one exterior angle can be found by subtracting each interior angle from 360°:
360° - 135° = 225°.
Therefore, one exterior angle of the polygon is 225°.

Three vertices of a parallelogram are located at (-4, 3), (1, -2), and (-1, 4). What are
two possible locations of the fourth vertex? Explain your reasoning.
The two possible locations of the fourth vertex are (4, -1) and (-6, 9). The solution has been obtained by using the properties of parallelogram.
What is a parallelogram?
A parallelogram has two sets of parallel sides, making it a quadrilateral. A parallelogram's opposing sides and angles are both the same length.
Finding the vector that depicts the shift from one of the given vertices to another is necessary in order to determine the fourth vertex of a parallelogram.
The third given vertex must then be added to the vector.
We know that the opposite sides of a parallelogram are parallel and equal in length, we may determine the coordinates of the other two vertices by adding the same displacement vector to two of the given vertices.
The difference between the first and second provided vertices i.e.
(1 - (-4), -2 - 3), is one potential displacement vector which is (5, -5).
On adding this vector to the third vertex, we get the fourth vertex as (4,-1).
Similarly, the difference between the second and third vertices i.e.
(-1 - 1, 4 - (-2)) is another potential displacement vector which is (-2, 6).
On adding this vector to the third vertex, we get the fourth vertex as
(-6, 9).
Hence, the two possible locations of the fourth vertex are (4, -1) and
(-6, 9).

Given that, Jaelyn had $150 in the school account and sold tickets for the fundraiser at a cost of $8 per ticket.
and Erik had $480 in his school account and sold tickets for the fundraiser at a cost of $6 per ticket.
Let they sold x tickets and they have the amount in their account is y.
After sold tickets, Jaelyn accounts had the amount is
y = 150 + 8x
After sold tickets, Erik accounts had the amount is
y = 480 + 6x

The average thickness of the metal sheet is 0.0423 inches.
What do you mean by average?In statistics, the mean is a measure of central tendency of a set of data. It is also referred to as the arithmetic mean and is calculated by adding up all the values in the data set and dividing by the total number of values.
Mean = (sum of all values) / (number of values)
For example, suppose we have the following set of data: 5, 7, 9, 11, 13. To find the mean, we add up all the values and divide by the total number of values, which is 5 in this case:
Mean = (5 + 7 + 9 + 11 + 13) / 5
Mean = 9
Therefore, the mean of this data set is 9.
The mean is a commonly used measure of central tendency because it takes into account all the values in the data set and is sensitive to changes in the data. However, it can be affected by outliers or extreme values in the data set, which can skew the results.
To find the average thickness of the sheet, we need to add the five measurements together and then divide by 5 (the number of measurements):
Average thickness = (0.0401 + 0.0417 + 0.0462 + 0.0407 + 0.0428) / 5
Average thickness = 0.0423 in
Therefore, the average thickness of the metal sheet is 0.0423 inches.

Solve the following quadratic equation using the quadratic formula. Separate multiple answers with a comma if necessary.
y2+7y−2=0
The quadratic equation y2 + 7y - 2 = 0 can be solved using the quadratic formula, which states that the solutions for x in the equation ax^2 + bx + c = 0 are given by:
x = (-b ± √(b^2 - 4ac)) / 2a
We can apply the quadratic formula to this equation by letting a = 1, b = 7, and c = -2:
y = (-7 ± √(7^2 - 4 * 1 * -2)) / 2 * 1
y = (-7 ± √(49 + 8)) / 2
y = (-7 ± √57) / 2
So the solutions to the equation y2 + 7y - 2 = 0 are:
y = (-7 + √57) / 2
y = (-7 - √57) / 2
The solutions to the equation are y = (-7 + √57) / 2 and y = (-7 - √57) / 2.
When we are given the value of the ______ variable, we can use the least-squares regression line to predict the value of the ______ variable.
When we are given the value of the explanatory variable, we can use the least-squares regression line to predict the value of the outcome variable.
The least square method is the process of finding the best-fitting curve or line of best fit for a set of data points by reducing the sum of the squares of the offsets (residual part) of the points from the curve. During the process of finding the relation between two variables, the trend of outcomes is estimated quantitatively. This process is termed as regression analysis. The method of curve fitting is an approach to regression analysis. This method of fitting equations that approximates the curves to give raw data is the least squares.
It is quite obvious that the fitting of curves for a particular data set is not always unique. Thus, it is required to find a curve having a minimal deviation from all the measured data points. This is known as the best-fitting curve and is found by using the least-squares method.

The nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 9 grams of dietary fiber. At that rate, find how many calories and grams of fiber are in a 2/3-cup serving.
Answer:
Step-by-step explanation:
To find the number of calories and grams of fiber in a 2/3-cup serving, we can simply multiply the values for a 1/2-cup serving by the appropriate factor. A 2/3-cup serving is 1.5 times larger than a 1/2-cup serving, so we multiply the calorie and fiber content by 1.5.
210 calories * 1.5 = 315 calories
9 grams of fiber * 1.5 = 13.5 grams of fiber
So a 2/3-cup serving would contain 315 calories and 13.5 grams of fiber.

y = -x - 4
We need to find 2 points to plot a straight line
Choose x = 0 ==> y = - 0 - 4 = -4
So (0, - 4) is one point
Choose another value for x. x = -4 is a good point
At x = - 4, y = -(-4) - 4 = 0
So (-4, 0) is another point.
Plot these two points on the graph and draw a straight line through those points

A deli is trying out new labels for their cylindrical-shaped wheels of cheese. The label covers the entire wheel except the circular top and bottom.
If the wheel has a radius of 30 centimeters and a height of 20 centimeters, how many square centimeters of the wheel does the label cover? (Approximate using pi equals 22 over 7)
792,000 over 7 square centimeters
66,000 over 7 square centimeters

2,640 over 7 square centimeters
The label covers approximately 4,800 square centimetres of the wheel of cheese.
What is the lateral surface area of a cylinder?
The lateral surface area of a cylinder can be found using the formula:
L = 2πrh
where L is the lateral surface area, r is the radius of the cylinder, and h is the height of the cylinder.
In this case, we need to find the lateral surface area of the wheel of cheese, so we can use the given radius of 30 centimetres and height of 20 centimeters to calculate:
L = 2 x (22/7) x 30 x 20
L = 4,800 square centimetres
This is the total surface area of the cylindrical-shaped wheel of cheese. However, the label does not cover the circular top and bottom, so we need to subtract their areas from the total surface area to find the area covered by the label.
The area of a circle can be found using the formula:
A = πr²
where A is the area of the circle, and r is the radius of the circle.
In this case, we have two circles (top and bottom), so the total area of the circles that are not covered by the label is:
2 x (22/7) x 30²
= 56,400/7 square centimeters
Subtracting this from the total surface area, we get:
4,800 - 56,400/7
= 33,600/7 square centimeters
= 4,800 square centimeters (rounded to the nearest whole number)
Therefore, the label covers approximately 4,800 square centimeters of the wheel of cheese.
