Answer:

A) ΔABC ≅ ΔEDC

Step-by-step explanation:

To prove triangles congruent with the AAS method, you need two angles and the non-included side of one triangle to be congruent to the corresponding parts of another triangle.

Let's see what we have in these two triangles.

Side AB is congruent to side ED. This is one pair of sides.

Angle A is congruent to angle E. This is one pair of sides.

Now we need a second pair of angles, that will make the two sides not-included in the angles.

By the congruence of vertical angles, we see that angles ACB and ECD are congruent. This is another pair of congruent angles.

We have two angles and a non-included side of one triangle congruent to two angles and a non-included side of another triangle. The triangles are congruent by AAS.

Answer: A) ΔABC ≅ ΔEDC

Answer:

2 y^2 - 9

Step-by-step explanation:

(-3y^2 − 8) − (-5y^2 + 1)

Distribute the negative sign

(-3y^2 − 8) + 5y^2 - 1

Combine like terms

-3y^2 + 5y^2 - 1 − 8

2 y^2 - 9

Answer:

The answer to (-3y² - 8) - (-5y² + 1) is 2y² - 9

Step-by-step explanation:

[tex](-3y^2-8)-(-5y^2+1)[/tex]

Since there is a minus sign in front of the second parentheses, then the terms within that parentheses will be changed to their opposite signs.

Answer:

Ox+y+z=180

Step-by-step explanation:

The relationship which is always rue for the three angles x, y and z of triangle ABC is x + y + z = 180°.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

We know that a triangle has three angles.

Let x, y and z be the three angles of the given triangle.

We know that, the interior angles of a triangle sum up to 180°.

The given three angles are x, y and z.

So, x + y + z = 180°

Hence the correct relationship that describes all the three angles of the triangle is that x + y + z = 180°.

Step-by-step explanation:

Jesse had $421.56 dollars in his checking account

Now he deposited g twenty-dollar bills

Now new amount =$421.56+20g

Now he deposited k quarters

1 quarter = 0.25

k quarters = 0.25k

So, Amount in the account = 421.56+20g+0.25k

Answer:

Step-by-step explanation:

since it is asking for the modal that means the most so it would be 3 teachers, and when asking the median we have to change the order so it would be 2,3,4,6 and we find the middle so it would be 3.5, and the mean is the total of the numbers divided by how many numbers there are so it would 2+6+4+3=

15/10 = 1.5

A mean is an arithmetic average of a set of observations. The model number, median, and mean of the number of teachers in a car are 3, 3, and 2.46667, respectively.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

The given table can be written in the data form as 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4.

A.) The modal number is the mode of a given data set. Therefore, the mode of the given data set is 3.

B.) The median is the middle number of a given data set. Therefore, the median is 3.

C.) The mean is the average number of teachers in a car. Therefore, the mean is,

Mean = (1+1+1+2+2+2+2+3+3+3+3+3+3+4+4)/15 = 37/15 = 2.46667

Hence, the model number, median and the mean of the number of teachers in a car is 3, 3, and 2.46667, respectively.

Answer:

t = 5 sec

Step-by-step explanation:

h = - 16t² + 32t + 240

On the ground h = 0.

- 16t² + 32t + 240 = 0 / : (- 16)

t² - 2t - 15 = 0

(t-5)(t+3) = 0

t = 5, t = - 3

Time can be only positive, so t = 5 sec

Answer:

C

Step-by-step explanation:

By observation, we can see very clearly that NR and QS are neither parallel nor perpendicular. Hence we can ignore A and B.

We notice that VT and VU are the same length.

Hence we can conclude that NR and QS must also be the same length (i.e they are congruent)

Therefore C is the answer.
