Answer:

  m∠T = 45°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so ...

  (2x +10)° +(3x -9)° +(6x -19)° = 180°

  11x -18 = 180 . . . . . collect terms, divide by °

  11x = 198 . . . . . . . . add 18

  x = 18 . . . . . . . . . . . divide by 11

Then the angle of interest is ...

  m∠T = (3x -9)° = (3·18 -9)°

  m∠T = 45°

_____

The other angles are ...

  m∠S = 46°

  m∠U = 89°

Step-by-step explanation:

Given the expression

[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y[/tex]

Remove the parentheses

[tex]=-4y-16-8y+10+2y[/tex]

[tex]=-10y-16+10[/tex]

Therefore, the equivalent expression with 3 terms for the expression is:

There are two bags containing only yellow and orange marbles. Bag A has 9 yellow marbles and 3 orange marbles. Bag B has 7 yellow marbles and 13 orange marbles. A marble is randomly chosen from each bag. List these events from least likely to most likely. Event 1 : choosing a yellow or orange marble from Bag B. Event 2 : choosing a red marble from Bag A. Event 3 : choosing an orange marble from Bag B. Event 4 : choosing a yellow marble from Bag A.

Answers

Answer:

Event 2, Event 3, Event 4, Event 1

Step-by-step explanation:

The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.

The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.

The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A  9 out of 12 times.

The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.

There are 3 consecutive integers that sum to 51. What is the greatest integer of the three?
O 17
O
19
O 18
O 20

Answers

Answer:

C. 18

Step-by-step explanation:

Let's say the first number is x so the second will be x+1 and the third will be x+2

x+ x+1+x+2=51

3x+3=51

3x=51-3

3x=48

3x/3=48/3

X=16 this is the first number

The second number will be x+1=16+1=17

The third number will be x+2=16+2=18

So the greatest number will be 18

184500 $ are to be divided between 2 people. One person has 80% of what the other person has. How much does each one receive in $?​

Answers

Given:

$184500 are to be divided between 2 people.

One person has 80% of what the other person has.

To find:

The amount each one receive in $.

Solution:

Let $x be the amount received by first person. Then,

Amount received by the second person = 80% of x

                                                                   = 0.80x

Total amount = Amount received by first person + by second person

                      =[tex]x+0.80x[/tex]

                      =[tex]1.80x[/tex]

Total amount is 184500. So,

[tex]1.80x=184500[/tex]

[tex]x=\dfrac{184500}{1.80}[/tex]

[tex]x=102500[/tex]

So, the amount received by the first person is $102,500.

[tex]0.80x=0.80\times 102500[/tex]

[tex]0.80x=82000[/tex]

So, the amount received by the second person is $82,000.

  hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.

Answers

Answer:

Angle θ would be about 17.1 degrees.

Step-by-step explanation:

To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².

c = √4² + 13²

Square 4 and 13 to get 16 and 169 respectively.

c = √16 + 169

Add 16 and 169 to get 185.

c = √185

Find the square root of 185 (I'll round to the nearest tenth.)

c = 13.60147 ≈ 13.6 units

To find angle β, divide AC by AB and find the inverse sine of that.

β = arcsin(13/13.6)

Divide 13 by 13.6. Round to the nearest thousandth.

β = arcsin(0.955)

β ≈ 1.2723 rad

To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.

β ≈ (1.2723 * 57.2957795)°

β ≈ 72.8974203 ≈ 72.9 degrees

Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

MN0 with vertices M(4,-5), N(5,-8), O(8, -6) ; translate the new figure M'N'O' (-2,5)

if possible please do this with an online graph

Answers

If you are translating a graph (-2,5), the easiest way to find the new points is to subtract the x value of each coordinate (M, N, and O) by 2. This will give you the new x values for the translated coordinates. Then, to find the new y values, add 5 to the y values of each coordinate. Then put the new x value and new y value in the form of a coordinate, and that will be your answer.
