Determine if the figures are similar. If they are, what is the scale factor from the first figure to the second figure?

Answer:

x/x+1

Step-by-step explanation:

[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]

start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)

So the fraction would be 4n/4(x-1)

Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses

The new equation would be

n*n-1/n+1

Now just multiply:

x/x+1

Answer:

B.) n/(n+1)

Step-by-step explanation:

Answer: l=50 m, w=20 m

Step-by-step explanation:

Given

A rectangular city has an area of [tex]1000\ m^2[/tex]

Also, length is 10 m more than twice its width

suppose width is w

So, length is given by

[tex]\Rightarrow l=10+2w[/tex]

The area is given by

[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]

subtract 4

3x = 18

divide by 3

x = 6

Answer:

x=6

Step-by-step explanation:

Subtract 4 from each side of the equation to get 3x=18. divide 18 by 3 to get 6, and divide 3x by 3 to get x. x=6

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

Your problem should be set up like so:

[tex] \frac{1}{6} \div \frac{2}{6} [/tex]

When dividing fractions you multiply by the reciprocal of the second fraction. Therefore your question changes to this:

[tex] \frac{1}{6} \times \frac{6}{2} [/tex]

You multiply as across as normal and you'll end up with

[tex] \frac{6}{12} [/tex]

Which when simplified gives you

[tex] \frac{1}{2} [/tex]

Answer:

The bigger angle is 135, and the smaller angle is 45.

Step-by-step explanation:

First, you have to know that supplementary angles add up to 180°.

We have no equations for the angles, so I will use the variable x for the value of the smaller x.

The reason for this: the problem gave the value of the bigger angle, but relative to the smaller angle. Therefore, it would be safe to assume the use of a variable for the smaller angle.

Since the bigger angle is 3 times as large as the smaller, we can say that the bigger angle is 3x, or 3 times x.

Now, we can put this in an equation: 3x+x=180. Like I said before, both of the angles add up to 180 degrees.

To solve the equation:

1. Combine like terms

4x=180

2. Divide both sides by 4

x=45

Now that we have the value of x, we can plug that in to 3x and x to find the angles.

3*45=135, which is the bigger angle

45, which is the smaller angle.

Answer:

slope 1/2

Step-by-step explanation:

The length of the 1 inch nail weighing 18 mg is 25.4 mm

An equation is an expression showing the relationship between numbers and variables.

Weight is the quantity of matter stored in an object. The SI unit of weight is the kilograms.

1 inch = 0.0254 meter

1 m = 1000 mm

Given the nail is 1 inch, hence:

1 inch = 0.0254 m

0.0254 m = 0.0254 m * 1000 mm/m = 25.4 mm

The length of the nail is 25.4 mm

Answer:B i think if wrong im so sorry

Step-by-step explanation:

Answer:

B 75+25h

Step-by-step explanation:

$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Answer:

m<A=94

Step-by-step explanation:

(2x+10)+(2x+2)=180

4x+12=180

-12 -12

4x=168

/4 /4

x=42

m<A= 2x+10

m<A=2(42)+10

m<A=84+10

m<A=94

Check:

Add m<A and m<B which should equal 180.

m<B=2x+2

m<B=2(42)+2

m<B=84+2

m<B=86

94+86=180

Given:

The area model for [tex]2.1\times 3.2[/tex].

To find:

The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

[tex]2\times 3=6[/tex]

[tex]2\times 0.2=0.4[/tex]

[tex]0.1\times 3=0.3[/tex]

[tex]0.1\times 0.2=0.02[/tex]

The complete area model is shown below.

After adding all areas of the area model, we get

[tex]6+0.4+0.3+0.02=6.72[/tex]

Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
