Need help plz!!!!!!!!???????

Answers

Answer:

x=16º

Step-by-step explanation:

The sum of angles in a triangle is 180º.

So,

39 + 125 + x = 180

Solve for x.

164 + x = 180

x = 180-164

x= 16

I’m pretty sure the answer is X= 16°

Michael cut 1/5 from a round dessert.Isrel cut a pice from the same dissert with an angle measure of 45 degrees who cut the larger piece?

Answers

Answer:

Michael cut the lrger piece

Step-by-step explanation:

a circle has 360 degrees

360:5=72° -> michaels piece

45°<72°

Step-by-step explanation:

Michael cut 1/5 of a round dessert.

Round dessert is a circke so total angle in 360.

Now, 1/5 of 360 = 360/5 = 72

72 > 45

So Michael cut the larger piece.

A school group is planning a trip to New York City. There
are 29 people going on the trip. They spent a total of
$19,111. They agreed to share the total cost of the trip
equally. Let "s" equal each person's share of the cost.
What is each person's share of the cost?

Answers

Answer:

$659

Step-by-step explanation:

This a basic algebra question with set up.

The total cost is 19,111 with 29 people going and s being each person's cost.

19,111 = 29s

[tex]\frac{19111} {29}[/tex][tex]=s\\[/tex]

so

$659

Answer:

S=$659

Step-by-step explanation:

You have to divide 29 by 29 which give you 1 so cross that out, then do 19111 divided by 29 which is 659, so s=659.

Triangle FGH is dilated by a scale factor of 5 to form triangle F'G'H'. Side F'G'
measures 15. What is the measure of side FG?

Answers

Answer:

The measure of side FG is 3.

Step-by-step explanation:

Dilation is a process in which the dimensions of a given shape or figure is either increased or decreased by a scale factor to produce its image.

From the given question,

scale factor = 5

measure of side F'G' = 15

Thus,

scale factor = [tex]\frac{measure of side F'G'}{measure of side FG}[/tex]

side F'G' = scale factor x side FG

⇒ 15 = 5 x side FG

So that,

side FG = [tex]\frac{15}{5}[/tex]

             = 3

The measure of side FG is 3.

The word and in probability implies that we use the​ ________ rule.

Answers

Answer:

Addition Rule

The word or in probability implies that we use the Addition Rule.

The word "and" in probability implies that we use the "Multiplication Rule".

The Multiplication Rule is used when calculating the probability of two or more independent events occurring simultaneously.

It states that the probability of two or more independent events occurring together is equal to the product of their individual probabilities.

In other words, if event A and event B are independent, then the probability of both events A and B happening is given by:

P(A and B) = P(A) x P(B)

1. The ordered pair IS a solution to the equation

2. The ordered pair IS NOT a solution to the equation

Answers

the answer is number 2

Answer:

The ordered pair IS NOT a solution to the equation

Step-by-step explanation:

To see if it is or is not a solution, plug in the point into the equation:

9 - 5y = 4x

9 - 5(3) = 4(-6)

Simplify:

9 - 15 = -24

-6 = -24

-6 [tex]\neq[/tex] -24

So, since this is false, the ordered pair is NOT a solution to the equation
