The measure of an angle is 14 times the
measure of its supplementary angle.
What in the measure of each anale?

Answers

Answer:

The smaller angle is 12 and the larger angle is 168

Step-by-step explanation:

Let call the measure of the random angle a. There is a angle that is 14 times of that and supplementary to that the random angle. So that is represented by

[tex]14a[/tex]

Supplementary Angles add up to 180 degrees so let set up an equation

[tex]a + 14a = 180[/tex]

which equal after you combine like with like

[tex]15a = 180[/tex]

Divide 15 by both sides and a=12 and the so smaller angle is 12 and the larger angle is 168

Answer:

A line is a infinite set of points, forming a straight path. It does not have a beginning or an end. A line segment is a part of a line made by two endpoints. A ray is a part of a line with only 1 endpoint, and stretches forever in the other direction. They are all types of geometric symbols I guess.

Plot the image of point B under a dilation about point P with a scale factor of 1/4

Answers

Answer:

When we have a point (x, y) and we have a dilation of scale factor K about the origin, the new coordinates of the point will be:

(k*x, k*y)

In this case we have a dilation about point P, but let's assume that point P is the origin of coordinates.

Then the coordinates of point B will be (8, 12)

Then after the dilation of scale factor of 1/4, the new coordinates will be:

( (1/4)*8, (1/4)*12) = (8/4, 12/4) = (2, 3)

This means that the dilated point will be 2 units at the right of P, and 3 units above P.

An example image can be seen below.

Write an equation of the line that contains point (-5,2) and is parallel to the y-axis

Answers

Answer: x = -5 (rewritten: x + 5 = 0)

Step-by-step explanation:

First, we must take into account that the line is parallel to the y-axis. If a line is parallel to the y-axis, it is vertical, meaning that for every y-value, there can only be one x-value. Since the question contains a point that the line passes through, which is (-5, 2), we know that for every y-value of the line, the x-value will always equal -5. Thus, the equation of the line must be x = -5 (or, rewritten, x + 5 = 0).

The value of the equation is 6

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A

The difference of ( 20 - 2 ) and 1/3 rd of that value

The equation is given as A = ( 1/3 ) ( 20 - 2 )

So , the equation can be simplified as

20 - 2 = 18

And ,

A = 18 x ( 1 / 3 )

A = 6

Hence , the value of the equation is 6

The Moore family’s backyard is shaped like a trapezoid as shown. The area of the backyard is 8,580 square feet. What is the perimeter of the yard? Explain how you found your answer.

Answers

Answer:

See Explanation

Step-by-step explanation:

Your question do not have enough details for it to be answered. I will solve your question on a general terms using the attached image of a trapezoid

Given

[tex]Area = 8580ft^2[/tex]

From the attachment, we have:

[tex]BC = 100ft[/tex]

[tex]AD = 80ft[/tex]

[tex]h = 60ft[/tex] --- height

The perimeter (P) of a trapezoid is:

[tex]P = AB + BC + CD + AD[/tex]

Substitute values for AD, BC

[tex]P = AB + 100 + CD + 80[/tex]

Collect Like Terms

[tex]P = AB + CD + 80+ 100[/tex]

[tex]P = AB + CD + 180[/tex]

Next, is to calculate the lengths of AB and CD or the sum: AB + CD

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(AB + CD) * h[/tex]

Substitute values for Area and h

[tex]8580= \frac{1}{2}(AB + CD) * 60[/tex]

Multiply both sides by 2

[tex]2*8580= \frac{1}{2}(AB + CD) * 60*2[/tex]

[tex]17160= (AB + CD) * 60[/tex]

Divide both sides by 60

[tex]\frac{17160}{60}= \frac{(AB + CD) * 60}{60}[/tex]

[tex]286 = AB + CD[/tex]

[tex]AB + CD=286[/tex]

Substitute 286 for AB + CD in: [tex]P = AB + CD + 180[/tex]

[tex]P = 286 + 180[/tex]

[tex]P = 466[/tex]

The perimeter of the backyard is 466ft.

A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 25 minutes? In 1 hour?

Answers

Answer:

https://i.pinimg.com/originals/50/3f/9a/503f9a49a2faa03f7db90f090eea6bff.gif

Step-by-step explanation:

Answer:

Given:

A car travels 2 1/3 miles in 3 1/2 minutes.

We need to find the distance travelled in 25 minutes, in 1 hour.

So, 2 1/3= 7/3 and 3 1/2 = 7/2

Let's convert them into decimals by dividing them completely.

So, we will get 2.33 miles and 3.5 minutes.

So now we have that 2.33 miles are covered in 3.5 minutes.

Now we need to know the distance covered in 1 minute.

So, 2.33/3.5=0.67

So now we have in one minute 0.67 miles are covered.

Now distance covered in 25 minutes will be:

0.67*25 = 16.75 miles

Now distance covered in one hour:

1 hour = 60 minutes.

So, 0.67*60 = 40.2 miles

So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.
