The sum of the angle of the triangle is 180 degrees. Then the measure of angle ∠D is 75.5°.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Given

In triangle DEF, the measure of angle ∠F is 12.4° and the measure of angle ∠E is 92.1°.

Then the measure of angle ∠D will be.

We know that the sum of the angle of the triangle is 180 degrees. Then

     ∠D + ∠E + ∠F = 180°

∠D + 92.1° + 12.4° = 180°

On simplifying, we have

∠D = 180 - 92.1 - 12.4

∠D = 75.5°

Thus, the measure of angle ∠D is 75.5°.

More about the triangle link is given below.

https://brainly.com/question/25813512

Final answer:

The measure of angle EDF in triangle DEF, given the measures of angles DFE and DEF, is 75.5 degrees, found by subtracting the sum of the known angles from 180 degrees.

Explanation:

To find the measure of angle EDF in triangle DEF where the measure of angle DFE is 12.4 degrees and the measure of angle DEF is 92.1 degrees, we can use the fact that the sum of the internal angles in any triangle is always 180 degrees. By subtracting the measures of angles DFE and DEF from 180 degrees, we can find the remaining angle's measure.

Angle EDF = 180 degrees - (Angle DFE + Angle DEF) = 180 - (12.4 + 92.1) degrees = 180 - 104.5 degrees = 75.5 degrees.

To find the portion of the beaker filled, consider the total volume of the beaker and the volume up to which it is filled. Perform division and multiply by 100 to get the percentage filled.

To determine the portion of the beaker filled, one must first understand the metrics of a beaker. A beaker is a cylindrical container with a flat bottom used to measure liquids. The scale etched on the side of the beaker represents the volume it contains. Suppose the total volume from the bottom up to the line of liquid is 300 mL and the total capacity of the beaker is 500 mL. By performing a simple division, 300 mL divided by 500 mL=0.6. Therefore, approximately 60% of the beaker would be filled. This is an approximate measure and for more accuracy, one should use a graduated cylinder.

➷The answer is point X.

Explanation: If you can see the graph, You can see that there are two points that are on the left, which is negative for the first number. Then, the second number, the Y position, which is 2, goes up, not down. So the right one is point X.

✽

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

DOGE

The point X has the given coordinates (-3 1/2, 2).

A point on the graph can be read as a point (x, y) where y is the perpendicular distance of the point from the x-axis and x is the perpendicular distance of the point from the y-axis.

If the point is left to the y-axis, we take the distance negative.

If the point is below the x-axis, we take the distance negative.

We are asked which point in the graph represents the point (- 3 1/2, 2).

To answer the question, we will analyze all the points to determine their coordinates.

Point W:

The perpendicular distance from the y-axis (x) = 2 units.

The perpendicular distance from the x-axis (y) = 3 1/2 units.

∴ The point W is (2, 3 1/2).

Point X:

The perpendicular distance from the y-axis (x) = 3 1/2 units.

The perpendicular distance from the x-axis (y) = 2 units.

∵ The perpendicular distance from the y-axis (x) is on the left side of the y-axis, we take x = 3 1/2 as negative, that is, x = -3 1/2.

∴ The point X is (-3 1/2, 2).

Point Y:

The perpendicular distance from the y-axis (x) = 2 units.

The perpendicular distance from the x-axis (y) = 3 units.

∵ The perpendicular distance from the y-axis (x) is on the left side of the y-axis, we take x = 2 as negative, that is, x = -2.

∵ The perpendicular distance from the x-axis (y) is below the x-axis, we take y = 3 as negative, that is, y = -3.

∴ The point Y is (-2, -3).

Point Z:

The perpendicular distance from the y-axis (x) = 2 units.

The perpendicular distance from the x-axis (y) = 3 units.

∵ The perpendicular distance from the x-axis (y) is below the x-axis, we take y = 3 as negative, that is, y = -3.

∴ The point Z is (2, -3).

∴ We can say that point X has the given coordinates (-3 1/2, 2).

Answer:

D

Step-by-step explanation:

Since the ordered pairs are linear then the slope m between corresponding points will be equal.

To calculate m use the slope formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (2, 5)

m = [tex]\frac{5-7}{2-6}[/tex] = [tex]\frac{-2}{-4}[/tex] = [tex]\frac{1}{2}[/tex]

Repeat with (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (k, 11)

m = [tex]\frac{11-7}{k-6}[/tex] = [tex]\frac{1}{2}[/tex], that is

[tex]\frac{4}{k-6}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

k - 6 = 8 ( add 6 to both sides )

k = 14 → D

Answer:

Step-by-step explanation:

To find when Kesia records got to break even, we first need to find how much they made total per month.

Now we need to first find how much they made on January.

The production cost of January will be:

Production cost = 5486 x 1.13

Production cost = $6199.18

Now that we know the production cost, we need to solve first for the total revenue.

Total Sales Revenue = 5486 x 9.75

Total Sales Revenue = $53488.50

Now that we have both the revenue and the production cost, we need can find how much profit by:

Profit = Total Sales Revenue - Production cost - Overhead

Profit = 53488.50 - 6199.18 - 27714

Profit = $19575.32

So they made a profit of $19575.32 by the end of January.

Now we move on to the other months.

Production cost = 8191 x 1.13

Production cost = $9255.83

Total Sales Revenue = 8191 x 9.75

Total Sales Revenue = $79862.25

Profit = 79862.25 - 9255.83 - 21689

Profit = $48917.42

Now that we have the profit for 2 months, we simply add them together.

Current Value = 19575.32 + 48917.42

Current Value = 68492.74

By doing the same process with the rest of the months, we get:

Refer to Image.

We can see in the image that by May they reach a total profit of $149897.77.

Since Kesia records paid $148950, the company got to break even at the month of May.

Answer:

Step-by-step explanation:

You can put this solution on YOUR website!

Call the number of hardcover and paperback books, h and p.

Thus  

h + p = 8 and the value equation is

4h + 2p = 26

Now multiply the top one by four and subtract from the second one...we get

4h + 2p = 26

-(4h + 4p = 32)

----------------

-2p = -6

p = 3 so that

h = 5   x +  y = 8,    (1)

4x + 2y = 26,   (2)

where x and y are the numbers of hardcover and softcover books respectively.

To solve, multiply the equation (1) by 2 (both sides) and then distract it from the equation (2). You will get

4x - 2x = 26 - 16,   or

2x = 10,   or   x = 5 - the number of hardcover books purchased.

Then from the equation (1) you get y = 3.

Check. 4*x + 2*3 = 4*5 + 2*3 = 26. OK.

Answer: [tex] (8)^2\pi\ feet^2[/tex]

or

[tex]64\pi \ feet ^2[/tex]

Step-by-step explanation:

We are given that the diameter of a circle = 16 feet

Then the radius of the circle = [tex]r=\dfrac{d}{2}=\dfrac{16}{2}=\ 8 feet[/tex]

Also, the area of a circle is given by :_

[tex]A=\pi r^2[/tex] , where r is radius of the circle .

For r = 8 feet

The area of the circle = [tex]\pi (8)^2=\pi (64)=64\pi \ feet ^2[/tex]

Hence, the expression that gives its area in square feet =

[tex] (8)^2\pi \ feet^2[/tex]

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−x+3+x−5−x=x+10

Step 1: Simplify both sides of the equation.

3x−x+3+x−5−x=x+10

3x+−x+3+x+−5+−x=x+10

(3x+−x+x+−x)+(3+−5)=x+10(Combine Like Terms)

2x+−2=x+10

2x−2=x+10

Step 2: Subtract x from both sides.

2x−2−x=x+10−x

x−2=10

Step 3: Add 2 to both sides.

x−2+2=10+2

x=12

Answer:

x= 12

Step-by-step explanation:

Cancel xx on both sides.

3x-x+3-5-x=103x−x+3−5−x=10

3x-x+3-5-x3x−x+3−5−x to x-2x−2.

x-2=10x−2=10

3 Add 22 to both sides.

x=10+2x=10+2

10+210+2 to 1212.

Answer:

960 in^3

Step-by-step explanation:

Multiply the base by the height

Base: (12*8)/2=48

Height: 20

The volume of a triangular prism is the area of the base multiplied by the height.

Let's first identify our values:

20 in = height of prism

12 in = base of triangle

8 in = height of triangle

First, we need to calculate the area of the triangle. To calculate the area of the triangle, we multiply the base of the triangle by the height of the triangle. In this case, the base is 12 and the height is 8 so 12 × 8 = 96 and then we divide 96 by 2 and we will get a quotient of 48.

Finally, we will multiply the area of the triangle which is 48 by 20.

48 × 20 = 960[tex]in^{2}[/tex].

The Interquartile Range (IQR) is the spread of the middle 50% of data. It is found by subtracting the first quartile (Q1) from the third quartile (Q3). A larger IQR indicates more variability within the dataset.

Interquartile Range (IQR)

The spread of the middle 50% of data in a dataset is known as the Interquartile Range (IQR). It is a measure of statistical dispersion and part of the five-number summary commonly used in descriptive statistics. To calculate it, you subtract the first quartile value (Q1) from the third quartile value (Q3). This range covers the middle 50 percent of the data, indicating where the bulk of the values fall and providing a sense of variability. An example based on given data can illustrate where Q1 is at 64.5 and Q3 is at 70, thus the IQR is 70 - 64.5 = 5.5. A larger IQR indicates more variability within the middle portion of the dataset. It is used alongside other descriptive statistics like the median, range, and standard deviation to provide a comprehensive understanding of the data's distribution.
