Why can you use Linear Pairs and Vertical Angles to prove lines are parallel?

natta225 [31]

Answer:

The reason why linear pairs and vertical angles are used to prove lines are parallel is because they area transversal drawn through the parallel lines will form angles on each of the two parallel lines including;

1) Supplementary linear pairs and

2) Vertical angles

3) Alternate angles

Given that either;

a) The corresponding angles that form the linear pairs are congruent

b) The corresponding vertically opposite angles are congruent

c) The corresponding alternate angles are congruent, we have;

The two lines are said to be parallel.

The motion of an object was recorded by measuring the velocity of the object in meters per second at various times, as shown in

LekaFEV [45]

The regression equation that represents the relationship between velocity and time is:

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v), that is, time and velocity, are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.

What is DA equal to? Brainiest if correct and please show your answer.

Naddik [55]

Answer:

<h2>DA is equal to <u>25</u> or BA</h2>

Step-by-step explanation:

ABC

ADC

Since we know that line CA is equal to line CA because of <em>reflexive property</em>
Angle BAC and DAC are equal because of <em>definition of an angle bisector</em>
Angle ABC and ADC are equal because of <em>definition of an angle bisector</em>
This will give us <em>ASA</em>, proving to us that all sides and angles are congruent <u>(this was already given to us)</u>
So, if BA is 25, and we know that BA is congruent to DA, this tells us that DA is 25

Suppose a certain religious university has a ratio of approximately 90 males to 125 females enrolled as a students. If he curren

Nitella [24]

How many males and how many females would there be if the total enrollment is 15000?

Ratio is

90 males 15000 - x
------------- = ---------------
125 fem x

Then 90x = 1875000 - 125x, or 215x = 1875000

x = approx 8720 females
and 15000-8720, or 6279 males

If every male finds a dance partner, that would leave (8720-6279) females, or 2440, without dance partners. ;(

Check: is the male:female ratio near 90:125?

Is 6279:8720 approx equal to 90:125?

Yes. 0.72 (approx) = 0.72 (approx).
