Answer:

x = 36 degrees

y = 48 degrees

Step-by-step explanation:

The two given triangles are congruent

Hence, we can say that the interior angles are equal

We shall use the angle markings on each of the triangles

Using the markings, we can see that y is 48 degrees

Now, let us find the last angle measure of the first triangle

Mathematically, the sum of angles in a triangle is 180

Thus;

108 + 48 + A = 180

A = 180 - 48 - 108

A = 180 - 156 = 24

Now, the measure 2x-y is equal to this;

Hence;

2x -y = 24

2x = 24 + y

we have that y = 48

2x = 24 + 48

2x = 72

x = 72/2

x = 36 degrees

Answer:

7.5

Step-by-step explanation:

The probability of winning = 3 out of 20 ;

P(winning) = 3/20

Predicted Number of winnings if game is played 50 times ;

P(winning) * number of games played

(3 /20) * 50

0.15 * 50

= 7.5

Predicted Number of winnings = 7.5

Answer:7.5

Step-by-step explanation:

first you want to clarify the numbers which is 3 and 20 and your chance is 3/20 which equals 7.5 but round to the nearest whole number so 8,

6 more hours did Tremaine use the computer to play video games than to do research.

The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.

Given:

The percent for Video Game= 25%

and, percent for Research = 5%

So, 25% of  30 = 25 / 100 x 30 = 7.5

5% of 30 = 5/100 x 30 = 1.5

So, the the number of hour spend on more on Video game

= 7.5 - 1.5

= 6 hour

Answer:

Brooklyn earns four more dollars than Anna does each hour.

Step-by-step explanation:

So basically in order to get the amount ech of them recieve you would have to divide. So for Anna's since her least given number is 10 hours you would divide how much she earns (256) by how many hours she has been working (10) and you get 25.6

Now for Brooke she is given only one piece of evidence so you would use that she has been working for 26 hours and earns 769.6. So divide her earning by the hour and get 29.6

Subtract each of the answers (29.6-25.6) and you would get 4

Answer:

3g = 30

Step-by-step explanation:

Well, lets check each one to see if any leaves g = 0

12g = 0      (Given)

÷12   ÷12    (Get "g" on its own)

g = 0          (0 ÷ 12 = 0)

We know it is not this one since g = 0

3g = 30    (Given)

÷3     ÷3    (Get "g" on its own)

g = 10       (30 ÷ 3 = 10)

This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.

Just in case, I will do the other options just not as in-depth!

g + 8 = 8

   -8    -8

g = 0

9g = 0

÷9    ÷9

g = 0

Answer:

It seems that you are trying to find the length of hair of Florencia on Tuesday.

Given that length of the hair of Florencia on Monday = h centimeters

On Tuesday, she got hair cut.

So new length of the hair of Florencia on Tuesday = 75% of Monday value

= 75% of (h)

= 0.75* (h)

= 0.75h

Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.

Answer:

3/4h and 0.75h

Given:

The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).

To find:

The perimeter of the rectangle.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]

Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).

Using the distance formula, we get

[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]

[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]

[tex]AB=\sqrt{144}[/tex]

[tex]AB=12[/tex]

Similarly,

[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]

[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]

[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]

Now, the perimeter of the rectangle is:

[tex]Perimeter=AB+BC+CD+AD[/tex]

[tex]Perimeter=12+4+12+4[/tex]

[tex]Perimeter=32[/tex]

Therefore, the perimeter of the rectangle is 32 units.
