What is the relationship for angle 1 and angle 8

Answers

Answer 1

Answer:

Step-by-step explanation:

In this cofiguration, there are 8 angles. 4 equal one value and 4 are their supplements of the first 4.

6 and 80 and 2 and 3 are all equal to 80 degrees.

1 4 5 and 8 are the supplements. So whatever their value, they are all equal to the same thing. <1 = <8

They are supplementary to the 80 degree angle

<1 + 80 = 180 Subtract 80 from both sides

<1 = 180 - 80

<1 = 100

So angle 1 and <8 both equal 100 degrees.

Answer 2

Answer:

Alternate exterior angles.

Step-by-step explanation:

Alternate exterior angles are angles on opposing sides of the transversal and the outside of the parallel lines. Moreover, they are congruent. Therefore, ∠1 ≅ ∠8.

Step-by-step explanation:k12

Expressions (B), (C), and (D) are all equivalent to the given expression 1.3−4x−3.7.

What are expressions?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)

So, the expressions equivalent to 1.3−4x−3.7 are:

Solve: 1.3−4x−3.7

1.3−4x−3.7- 2.4 - 4x

Now, calculate for - 2.4 - 4x:

(A) −0.6−4−x:

-4.6 - x ≠ - 2.4 - 4x

(B) −4(x+0.6)

- 2.4 - 4x = - 2.4 - 4x

(D) −4x−2.4

- 2.4 - 4x = - 2.4 - 4x

Therefore, expressions (B), (C), and (D) are all equivalent to the given expression 1.3−4x−3.7.

When twelve is added to eight times a number, the result is one hundred and fifty. Find the
number.

Answers

Adding twelve eight times is the same as 12 x 8 which is 96

x + 96 = 150

To find 150, subtract 96 from both sides

x = 150 - 96
x = 54

Which number is rational?

Please help me

Answers

Answer:A

Step-by-step explanation:

Please answer the question step by step!

Answers

Answer:

Step-by-step explanation:

See the figure below.

This is how you graph directly from the equation in the slope-intercept form (y = mx + b) without having to create a table of x and y values.

The equation is

y = -2/3 x + 1

Compare it with

y = mx + b

b = 1

The y-intercept is 1, so mark 1 on the y-axis. (You already did.)

I placed a black dot there.

The slope is m.

m = -2/3

slope = m = rise/run

A slope of -2/3 can be though of as -2 rise and 3 run. That means start from the y-intercept, and go -2 in y (a rise of 2 down) and 3 in x (a run 3 right). Point graphed in red.

Mathematically, -2/3 is the same as 2/(-3), so starting again from the y-intercept, this slope can also be though of as rise of 2 in y (a rise of 2 up) and a run of -3 in x (a run of 3 left). Point graphed in green.

The line is graphed in blue.

Answers

Answer:

25 ft^2

Step-by-step explanation:

In direct variation, if y varies directly with x, then the equation has the form

y = kx,

where k is the constant of proportionality. y is proportional to x.

Let's call the area y and the distance x.

Here, the area varies with the square of the distance, so the equation has the form

y = kx^2

Here, y is proportional to the square of x.

We can find the value of k by using the given information.

y = kx^2

When x = 20 ft, y = 16 ft^2.

16 = k(20^2)

k = 16/400

k = 1/25

The equation of the relation is:

y = (1/25)x^2

Now we use the equation we found to answer the question.

What is y (the area) when x (the distance) is 25 ft?

y = (1/25)x^2

y = (1/25)(25^2)

y = 25

Answer: 25 ft^2
