The equation that shows the relationship between the angles in the triangle is m∠1 + m∠2 + m∠3 = 180.

The equation that shows the relationship between the angles in the triangle is determined as follows;

The sum of angles in a triangle is equal to 180 degrees.

So based on this information, the equation that shows the relationship between the angles in the triangle is formulated as;

angle 1 + angle 2 + angle 3 = 180

We can re-write the equation as follows;

m∠1 + m∠2 + m∠3 = 180

Thus, the equation that shows the relationship between the angles in the triangle is the sum of angle 1 plus angle 2 plus angle 3.

Answer:

M1=35, M2=77, M3=49, M4=77, M5=62, M6=28

Step-by-step explanatio

Answer:

Angle 1) 35

Angle 2) 77

Angle 3) 49

Angle 4) 77

Angle 5) 62

Angle 6) 28

Step-by-step explanation:

Start with angle 3)

You have 2 angles for this one already, 90 and 41

All angles in a triangle have the sum of 180, therefore

Angle 3 = 180 - 90 - 41

Angle 3 = 49

Next is Angle 6)

You have Angle 3 and 103

Angle 6 = 180 - 49 - 103

Angle 6 = 28

Now Angle 2)

Angle 2 is on the same line as 103 and are supplementary, the sum is 180

Angle 2 = 180 - 103

Angle 2 =  77

Angle 4)

2 and 4 are vertical opposites with the same measurement, so 77

Angle 1)

Using Angles 1 and 2 and 68, they have a sum of 180

Angle 1 = 180 - 77 - 68

Angle 1 = 35

Angle 5)

Now with Angle 4 and 41 thats given, Angle 5 is

180 - 77 - 41 = 62

A line with negative slope is always perpendicular to a line with positive slope, since perpendicular slopes (of non horizontal and non vertical lines) are opposite signs and reciprocals.

So, you have to be perpendicular to the blue line, since that's the one with a positive slope.  Since the slope of the blue line is "up 1, right 3" or 1/3 (found by getting from the y-intercept to the next point to the right) your line's slope is the opposite sign and reciprocal.

That makes your slope positive -3/1 or -3.

The value of a is 2

We can use the slope-intercept form of a line, y = MX + b, to find the equation of the line.

The slope (m) of the line can be found using the following formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

So, m = (5 - (-5)) / (4 - (-1)) = 10/5 = 2

Now, we can use the point-slope form of a line, y-y1 = m(x-x1)

where (x1,y1) is any point on the line and m is the slope of the line.

In this case, we will use the point (x1, y1) = (–1, –5)

so, y-y1 = m(x-x1) = -5 - 2(-1-x) = -5-2+2x

Now we know that the point (a,1) is also on the line, we can substitute the value of x and y in the equation

so, 1 - (-5) = 2(a - (-1))

1 +5 = 2a+2

6 = 2a+2

4 = 2a

a = 2

Therefore, the value of a is 2.

Answer:

Step-by-step explanation:

The volume formula can be used to find the height and width of a box with volume 4368 in³ and height 1 in greater than width.

The volume formula is ...

  V = LWH

Substituting given information, using w for the width, we have ...

  4368 = (24)(w)(w+1)

We want to find the value of w.

  182 = w² +w . . . . . . . . divide by 24

  182.25 = w² +w +0.25 = (w +0.5)² . . . . . . add 0.25 to complete the square

  13.5 = w +0.5 . . . . . . . . take the positive square root

  w = 13 . . . . . . . . . . . . subtract 0.5

  h = w+1 = 14

The height of the box is 14 inches; the width is 13 inches.

__

Additional comment

By "completing the square", we can arrive at the exact dimensions of the box, as we did above. Note that we only added 0.25 to the equation to do this.

For numbers close together, the geometric mean (root of their product) is about the same as the arithmetic mean (half the sum):

  \(\sqrt{w(w+1)}\approx\dfrac{w+(w+1)}{2}=w+\dfrac{1}{2}\\\\w\approx\sqrt{182}-\dfrac{1}{2}\approx12.99\)

Using this approximation to arrive at the conclusion w=13 saves the steps of figuring the value necessary to complete the square, then adding that before taking the root.

Answer:

The x intercept is -8

Step-by-step explanation:

To find the x intercept, set y = 0 and solve for x

5x - 10y + 40 = 0

5x - 10(0) +40 =0

5x +40 = 0

Subtract 40 from each side

5x = -40

Divide by 5

5x/5 = -40/5

x = -8

The lights on or off in the daytime is the independent variable. (option c).

The variable that you manipulate or control in your study is called the independent variable. In your case, the independent variable is whether the drivers have their headlights on or off during the daytime.

The dependent variable, on the other hand, is the variable that you observe or measure in your study. It is dependent on the independent variable, as it is expected to be affected by it.

A confounding variable is a variable that is not controlled for in a study and can affect the dependent variable. It is a potential source of bias that can make it difficult to determine whether the independent variable truly has an effect on the dependent variable.

Finally, the fact that the independent variable in your study is a random variable means that it is not under your control, but is determined by chance.

This is because you will randomly assign the drivers to the two groups, with some having their headlights on and others having their headlights off.

So, the correct option is (c).

Based on the fact that the two numbers multiply to 2,400 and add up to -16, the numbers are undefined.

Assume that one of the numbers is x and the other number is y, the system of equations to represent this is given that the two numbers add up to -16 and multiplying to 2,400:
x + y = -16

xy = 2,400

The the wind speed of a tornado with Beaufort number 9 is 51.3 miles per hour.

What is speed?

Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed. The units will be in meters per second (m/s) in this example because the distance is measured in meters (m) and the time is measured in seconds (s).

Given:

The Beaufort Scale measures the intensity of tornadoes. For a tornado

with Beaufort number B, the formula \(v = 1.9B^\frac{3}{2}\) may be used to

estimate the tornado's wind speed in miles per hour.

We have to estimate the wind speed of a tornado with Beaufort number 9.

Plug B = 9 in the formula \(v = 1.9B^\frac{3}{2}\)

⇒

\(v = 1.9(9)^\frac{3}{2} \\v = 1.9(27)\\v = 51.3\)

Hence, the the wind speed of a tornado with Beaufort number 9 is

51.3 miles per hour.

Answer:

Organic = 80pages & Non organic = 320pages.

Step-by-step explanation:

Organic:Non organic

2:8

• 2/10 x 400 = 80

• 8/10 x400= 320

Given parameters:

Ratio of organic to non-organic  = 2:8

Total number of pages in the book = 400

Unknown:

Number of pages of organic = ?

Number of pages of non-organic = ?

Ratios establishes the proportion of parts in a whole.

We can find the whole from the part and likewise the part from the whole if we know the ratio;

To solve this problem;

Sum up the ratio ; 2 + 8  = 10

Number of pages of organic = \(\frac{2}{10} x 400\)   = 80pages

Number of pages of non-organic = \(\frac{8}{10} x 400\)   = 320pages

We need 80 pages of organic and 320 non- organic pages to make up the chemistry book.

The given statement "An algorithm is a calculation that determines how long it will take to solve a problem." is False.

An algorithm is not just a calculation that determines how long it will take to solve a problem. An algorithm is a step-by-step set of instructions or a process used to solve a problem or perform a specific task. It is a systematic approach that allows a computer or human to break down a problem into smaller, manageable parts and reach a solution effectively.

Algorithms are the foundation of computer programming and can be applied in various fields such as mathematics, data processing, and problem-solving. They can be simple, like finding the largest number in a list, or complex, like solving a Rubik's Cube.

Efficiency is a key factor in evaluating algorithms. The time and resources required for an algorithm to solve a problem can vary greatly depending on the method used. However, the primary purpose of an algorithm is to provide a clear and concise procedure to reach a solution, rather than just estimating the time needed to solve a problem.

In summary, an algorithm is a well-defined process designed to perform a specific task or solve a problem, rather than just calculating the time required to do so. Its effectiveness depends on its efficiency, accuracy, and the simplicity of the steps involved.
