Enter an equation for the word sentence. Use the variable n.

The sum of a number and 4.4 is 8.1.

Answers

Answer:

[tex]n + 4.4 = 8.1[/tex]

Step-by-step explanation:

We know we have to write an algebraic equation for the sentence - so "translate" the phrases of the sentence step-by-step. Let the unknown number be represented by the variable n, as the question states.

Start with the phrase "the sum of a number and 4.4." A sum comes as a result of adding numbers together - therefore the first part of the equation must be [tex]n + 4.4[/tex].

Next, the sentence says "is 8.1." The "is" indicates that the expression we just wrote equals something, so that number must be 8.1. Therefore, the whole equation must be [tex]n + 4.4 = 8.1[/tex].

write the equation of the line in fully simplified slope-intercept form. (6, 10) (4,5) (-2,-10)

Answers

Answer: the equation will be  y = 5/2x -5

Step-by-step explanation:

First find the slope of the line by finding the change in the y coordinates and diving it by the change in the x coordinates.

(6,10)

(4,5)  

5 - 10 = -5

4 - 6 =  -2

Slope: 5/2

(4,5)

(-2,-10)

-10 - 5 = - 15

-2-4= - 6

-15/-6 = 5/2

Now we know the slope is 2, so use the formula y=mx + b to solve for the y intercept which is b by using one of the given points.

y = mx + b

5 = 5/2(4) + b

5 = 10 + b

b =   -5

Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y= 0.3x + 1; A(...;9), B(5;...) The slope is

Answers

Answer:

[tex]A = (\frac{80}{3},9)[/tex]

[tex]B = (5,2.5)[/tex]

The slope is 0.3

Step-by-step explanation:

Given

[tex]y = 0.3x + 1[/tex]

[tex]A = (-,9)[/tex]

[tex]B = (5,-)[/tex]

Required:

Fill in the gap and calculate the slope

In [tex]A = (-,9)[/tex]

[tex]y = 9[/tex] and x is ??

Substitute 9 for y in [tex]y = 0.3x + 1[/tex]

[tex]9 = 0.3x + 1[/tex]

Collect Like Terms

[tex]0.3x = 9 - 1[/tex]

[tex]0.3x = 8[/tex]

[tex]x = \frac{8}{0.3}[/tex]

[tex]x = \frac{80}{3}[/tex]

So:

[tex]A = (-,9)[/tex]

[tex]A = (\frac{80}{3},9)[/tex]

In [tex]B = (5,-)[/tex]

[tex]x = 5[/tex] and y is ??

Substitute 5 for x in [tex]y = 0.3x + 1[/tex]

[tex]y = 0.3 * 5 + 1[/tex]

[tex]y = 1.5 + 1[/tex]

[tex]y = 2.5[/tex]

So:

[tex]B = (5,-)[/tex]

[tex]B = (5,2.5)[/tex]

Calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2.5-9}{5 - \frac{80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{15- 80}{3}}[/tex]

[tex]m = \frac{-6.5}{\frac{-65}{3}}[/tex]

[tex]m = \frac{-6.5*3}{-65}[/tex]

[tex]m = \frac{-19.5}{-65}[/tex]

[tex]m = 0.3[/tex]

How do I do problems like this????​

Answers

Answer:

m<1 = 62°

m<2 = 45°

m<3 = 24°

Step-by-step explanation:

Hi!

Let me walk you through it!

The first step is to find angle 1.

Angle 1 is supplementary with the angle 118°

So we do 180° - 118° = 62°

m<1 = 62°

Then we find angle 2.

There are two ways to do this

The sum of interior angles in a triangle is 180°

So we do 180° - (73 + 62°)

Open parenthesis:

180° - 73° - 62° = 45°

You can also use the exterior angle theorem

118° = 73° + m<2

Same to both sides:

45° = m<2

So

m<2 = 45°

Now, using this information, we can find angle measure 3.

Now we look at the big triangle. Again, there are two ways to do this.

First way:

m<1 + 49° + m<2 + m<3 = 180°

Plug in known-values

62° + 49° + 45° + m<3 = 180°

Combine like terms:

156° + m<3 = 180°

Same to both sides:

m<3 = 24°

Second way:

Exterior angle theorem.

118° = m<2 + m<3 + 49°

Plug in known-values:

118° = 45° + m<3 +49°

Combine like terms:

118° = 94° + m<3

Same to both sides:

24° = m<3

So m<3 = 24°

There you go! You just need to take it step-by-step and you can get the answer. Be open-minded, don't just try to go for a certain angle, see what you can do, and work from there. It all comes together at the end.

Let me know if you have any questions, have a good day!

This hull enables them to float on the water very easily. Two small floats underneath its wings keep the flying boat stable in rough water. These seaplanes are usually larger and more stable on water than floatplanes are. A floatplane is a seaplane that has two long floats, called pontoons, under the fuselage. This is the only part of the plane that touches the water. Unlike flying boats, floatplanes often come in a wide variety of sizes. An amphibious vehicle can be either a flying boat or a floatplane with wheels. This allows the aircraft to land on both land and water.Which BEST describes the purpose of the paragraph?A.to explain how seaplanes are usedB.to encourage people to use seaplanesC.to list all of the types of seaplanesD.to describe the different parts of seaplanes What conclusion can be drawn from these statements about America's westward expansion?America's westward expansion was a peaceful and smooth processAs the American nation expanded westward, many groups faced challenges and had to deal with conflict.
