Find the measure of the exterior angle




The measure of the exterior angle of the triangle is
angle of the triangle is
º.

Answers

Answer:

9

Step-by-step explanation:

The exterior angle is equal to the sum of the 2 opposite interior angles, therefore:

9x + 9 = 45 × 5x

4x = 36

x = 9

9


9x +9 = 45+5x
4x = 36
x =9

Write an equation of the line that passes through (0,4) and (0,-3).

Answers

Answer:

It is a vertical line at x = 0

Step-by-step explanation:

An equation of a line in a slope-intercept form is y=mx+b

So with the coordinates given, we must find the slope (m), and the y-intercept (b).

In order to find the slope using these coordinates,

we have to use the formula (y2-y1)/(x2-x2).

So the slope would be -3 - 4 / 0.

Because the denominator is 0, the slope would be undefined.

It is easier to see the equation/graph by graphing the coordinates on the coordinate plane. You will see that it is a straight vertical line down x=0.

Hello there! :)

We can use the formula:

[tex]\frac{y2-y1}{x2-x1} \\[/tex]

First, let's take a look at the x-coordinates. They are the same, aren't they?

If the x-coordinates are the same, then the slope is undefined.

Put the x-coordinates into the formula. It turns out that we divide by 0, and division by 0 is undefined.

Hope this helps!

At a farm the ratio of cows to horses was 8 : 3. If there were 24 cows at the farm, how many horses were there?

Answers

9 Horses or 24:9

Since there are 24 cows we can do 24/8 and get 3. Then multiply the amount of horses by 3.

Circle A has a circumference of 25 centimeters.
Circle B's diameter is 3 times as long as circle A's
diameter.
What is the circumference of circle B?

Answers

The circumference of circle B would be; 74.98 cm.

What is the circumference of the circle?

The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

We have been given that Circle A has a circumference of 25 centimeters.

And Circle B's diameter is 3 times as long as circle A's diameter.

Thus, the Diameter of Circle B = 3 x the Diameter of Circle A

Since The circumference of the circle A = 2πr = 25

2πr = 25

r = 25/  2π

r = 3.98 cm

The Diameter of Circle A = 2 x 3.98 = 7.96 cm

Since Diameter of Circle B = 3 x the Diameter of Circle A

Diameter of Circle B = 3 x 7.96 cm

= 23.88 cm

Radius = 23.88 / 2

Hence, the circumference of circle B =  2πr

= 2 x 22/7 x 23.88 / 2

= 74.98 cm

Write three expressions that are equivalent to 8x + 16.

Answers

Answer:

1. 2(4x + 8)

2. 8(x +2)

3. 4(2x +4)

Step-by-step explanation:

You can check by using the distributive property!

For instance:

2 (4x +8)

 2 · 4x = 8x

 2 · 8 = 16

= 8x + 16

8(x +2)

 8 · x = 8x

 8 · 2 =16

= 8x + 16

4(2x +4)

  4 · 2x = 8x

   4 · 4 =16

= 8x + 16

A square has a side length of 4 centimeters. What is the length of the diagonal of the square? What is the length from the corner to the center of the square?​

Answers

Answer:

4[tex]\sqrt{2}[/tex] cm AND 2[tex]\sqrt{2}[/tex] cm

Step-by-step explanation:

The length of a diagonal of a square means finding the hypotenuse (long side) of a right triangle with legs of the length of the side of the square. This means you can use a^2 + b^2 = c^2 to solve for the diagonal. Plugging in your values gets you 4^2 + 4^2 = c^2, simplify to get 16 + 16 = c^2, simplify further to get 32 = c^2. Isolate c by taking the square root of both sides to get [tex]\sqrt{32}[/tex] = c, which you can simplify by listing out the factors of 32 and finding pairs. 32 = 2 * 2 * 2 * 2 *2 (5 of them), meaning its square root is 4[tex]\sqrt{2}[/tex], which is the length of the diagonal. Don't forget your units! (:

For the second part, remember that the distance between the corner to the center of a square is half the diagonal of the square. You already have the length of that diagonal, so all you have to do is divide it by 2. Do so and you get 2[tex]\sqrt{2}[/tex]. Once again, don't forget your units! (:

There are 133 students at a small school and 23 of them are freshmen. What fraction of the students are freshmen?

Answers

Answer:

23/133

Step-by-step explanation:

If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.

The total number of freshmen in the school is 23/133


The number of students in the small school is 133


23 out of the 133 students are freshmen


Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133


Fraction of freshmen is 23/133

The sum of two numbers is twenty-four. The difference of the two numbers is four.

Answers

Answer:

[tex]x + y = 24[/tex]

[tex]x - y = 4[/tex]

Now, add these two equations.

You get,

[tex]2x = 28[/tex]

[tex]x = \frac{28}{2} [/tex]

[tex]x = 14[/tex]

Given,

[tex]x + y = 24[/tex]

[tex]14 + y = 24[/tex]

[tex]y = 24 - 14[/tex]

[tex]y = 10[/tex]

You can test this to the other equation as well.

[tex]x - y = 4[/tex]

[tex]14 - 10 = 4[/tex]

Hence, the two numbers are 14 and 10.
