Answer:

1,092 feet

Step-by-step explanation:

set up a proportion, then cross multiply:

let 'x' = actual length, in feet

[tex]\frac{1}{120}[/tex] = [tex]\frac{9.1}{x}[/tex]

The length of the given aircraft with the given scale factor will be 108 feet.

You must specify the extent of the shape's enlargement when describing one.

For example, 50 meters is very big so we cannot measure it but if we can convert it into 50 mm such that the scale ratio is maintained then it will be easy to draw.

Suppose the aircraft's actual length is L.

The ratio of actual length to blueprint

L/(9 1/10) = L/0.9

As per the given scale factor,

1 inches = 120 feet

120 feet = 1440 inches

i inches = 1440 inches

Thus, 1440/1 = L(0.9)

L = 1296 inches = 108 feet

Hence "The length of the given aircraft with the given scale factor will be 108 feet".

50+45x

Step-by-step explanation:

Answer: x=4

Step-by-step explanation:

First, you need to take both of the x to one side of the equation. To do that, subtract 4x from both sides of the equation. you will get 9x-7-4x=4x+13-4x. The 4xs on the right hand side of the equation will cancel out. So you will be left with an equation that looks like this: 9x-7-4x=13. Now, on the left hand side of the equation you can rearrange the numbers to look like this. 9x-4x-7=13. Do 9x-4x to get 5x and then add back your -7 and the =13. Now, your equation will look like this. 5x-7=13. Now, you need to get rid of the 7 on the left hand side of the equation in order to isolate the variable (which is x here). The easiest way to do this would be to add 7 to both sides (in order to keep the equation balanced, whatever you do on one side of the equation has to also be done on the other side.) of the equation so the +7 and -7 could cancel each other out. You would have 5x-7+7=13+7. Now, cancel out the 7s on the left hand side of the equation. You would be left with 5x=13+7. Add the 13 and the 7 on the right hand side of the equation to get 20. You would now have the equation 5x=20. Finally, you need to isolate the x, right? To do that, just divide both sides of the equation by 5. you would get 5x/5=20/5. And your final answer after simplifying should be x=4. Hope this helps!

Answer:

Step-by-step explanation:

The slope-intercept form of equation is:  y = mx + b

where m is slope and b is y-intercept

If line y=ax+b passes through point (x₀,y₀) that means

that the equation y₀=ax₀+b is true

(-5, -2)    ⇒   x=-5,   y=-2

m = -⁶/₅

So:

              -2 = -⁶/₅ (-5) + b

               -2 = 6 + b

               b = -8

Therefore equation in  slope-intercept form:

                                                                     y = -⁶/₅x - 8

Answer:

  1 1/5

Step-by-step explanation:

We want to find the number of times (5/6) goes into 1, so we divide ...

  1/(5/6) = 1 × 6/5 = 6/5 = 1 1/5

There are 1 1/5 groups of 5/6 in 1.

_____

Another way to look at it

You can consider 1 to be divided into 6 equal part:

  o  o  o  o  o  o

We can group these in groups of 5, so each group is 5/6 of the whole:

 (o  o  o  o  o)  o

What we see is that we have 1 group, and 1/5 of another group.

That is, 1 has 1 1/5 groups of 5/6 in it.

Additional comment

The work shown is correct. You find x by writing and solving an appropriate equation. To solve the equation, undo the steps that are done to x. Undo addition by adding the opposite. Undo multiplication by diving by the multiplier. It often helps to collect terms before you start the "undo" steps.

For x on both sides of the equation (as in problems 4–6), you can subtract the term with the lowest coefficient. (Of course, you must subtract it from both sides of the equation.) In problem 5, if you do that, you get 1=1, which is true for any value of x. In problem 6, if you do that, you get 6=3, a false equation, indicating no value of x will make it true.

The Answer is:

1. x=2

2. x=4

3. x=44

4. x=4

5. x=any number

6. no such number

Answer:

You first multiply the 2 with the numbers inside the parinthesis. So it'll be 2 x 2w and 2 x -9 which will get you to 4w-18. After that you add 18 to each side of the equation so the -18 can dissapear. After getting your answer you get left with 4w on the left side and -20 on the right. You then divide both sides with 4

Step-by-step explanation:

2(2w-9)=-38

4w-18= -38

    +18  +18

4w = -20

4w/4= w

-20/4= -5

So in the end W= -5

This represents 30% of the total members of choir at the school.

Let,

x be the number of total sutdents

30% of x = 36

[tex]\frac{30}{100}x=36[/tex]

0.3x = 36

Dividing both sides by 0.3

Answer:

∠BOC = 100°

Step-by-step explanation:

Given that,

∠BOC = 25x

and

∠COD = 20x

We need to find the measure of ∠BOC.

BOD is a straight line. Here, linear pair will form. So,

∠BOC+∠COD=180

25x+20x=180

45x=180

x=4

So,

∠BOC = 25(4)

= 100°

So, the measure of ∠BOC is equal to 100°.

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Step-by-step explanation:

There are theoretically three unique triangles that can be formed with two side lengths of 10 centimeters and one 40º angle. We include a representation of possible triangles:

Case A - Law of Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]C = 40^{\circ}[/tex])

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex] (1)

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 40^{\circ}}[/tex]

[tex]c\approx 6.840\,cm[/tex]

Case B - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]B = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex] (2)

[tex]\sin A = \frac{a\cdot \sin B}{b}[/tex]

[tex]A = \sin^{-1}\left(\frac{a\cdot \sin B}{b} \right)[/tex]

[tex]A = \sin^{-1}\left[\frac{(10\,cm)\cdot (\sin 40^{\circ})}{10\,cm} \right][/tex]

[tex]A = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

Case C - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]A = 40^{\circ}[/tex])

[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]

[tex]\sin B = \frac{b\cdot \sin A}{a}[/tex]

[tex]B = \sin^{-1}\left(\frac{b\cdot \sin A}{a} \right)[/tex]

[tex]B = 40^{\circ}[/tex]

[tex]C = 180^{\circ}-A-B[/tex]

[tex]C = 100^{\circ}[/tex]

[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]

[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]

[tex]c \approx 15.321\,cm[/tex]

There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.

Answer:

[tex]\frac{17\pi }{6}[/tex]

Step-by-step explanation:

To convert from degrees to radians

radian = degree measure [tex]\frac{\pi }{180}[/tex]

           = 510 × [tex]\frac{\pi }{180}[/tex]

           = [tex]\frac{51\pi }{18}[/tex]

           = [tex]\frac{17\pi }{6}[/tex] radians

510 degrees is equal to (17π / 6) radians, which is determined by using the fact that 180 degrees is equal to π radians.

The given angle is  510°.

To convert 510 degrees to radians, we can use the fact that π radians is equivalent to 180 degrees.

First, we convert 510 degrees to radians by setting up a proportion:

180 degrees = π radians

510 degrees = x radians

Solving for x, we find:

x = (510 degrees) * (π radians / 180 degrees)

Simplifying the expression, we have:

x = (17π / 6) radians

Therefore, 510 degrees is equal to (17π / 6) radians.

Bob's land is a rectangle, so it has 2 long and 2 short sides. The Long side is 40 meters long, and the short side is 20 meters long.

Let's add them: 40 + 20 = 60 meters

Since we have 2 of those sides, we will multiply it by 2 which we can demonstrate as

60 meters * 2 = 120 meters
