if XYZ ~ RST, find RS​

Answers

Answer:

RS = 38

Step-by-step explanation:

20x - 12 = 18x + 12

2x = 24

x =  12

3(12) + 2 = 38

The value of the side of triangle RS is equal to 38.

What is the similarity?

If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.

The value of RS will be calculated as,

( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )

( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )

20x - 12 = 18x + 12

2x = 24

x = 12

RS = 3x + 2

RS = ( 3 x 12 ) + 2

RS = 36 + 2

RS = 38

Therefore, the value of the side of triangle RS is equal to 38.

Put the following equation of a line into slope-intercept form, simplifying all fractions.

Answers

Answer:

y=1/2x-2

Step-by-step explanation:

2y=-4+x

2y=x-4 divide both sides by 2

y=1/2x-4/2

y=1/2x-2

Answer:

[tex]y = 0.5x - 2[/tex]

Step-by-step explanation:

Slope intercept form is

[tex]y = mx + b[/tex]

Our initial goal is to isolate y.

[tex]2y - x = -4[/tex]

Add x to both sides of the equation.

[tex](2y - x) + x = (-4) + x[/tex]

Simplify.

[tex]2y =x -4[/tex]

Divide both sides by 2.

[tex]\frac{2y }{2} = \frac{(x - 4)}2}[/tex]

Simplify.

[tex]y = 0.5x - 2[/tex]

What type of angle relationship is shown?

Answers

Answer:

straight angle

Step-by-step explanation:

9x_15+2x_3=180

11x_18=180

11x=180+18

11x=198

x=198÷11

x=18

Answer:

The angles are a linear pair.

x = 18

Step-by-step explanation:

The angles are a linear pair, meaning the angles add up to 180 degrees.

(9x - 15) + (2x - 3) = 180

11x - 18 = 180

11x = 198

x = 18

55% of 6th grade students voted in the student election. 440 sixth grade students voted in the student election. How many total 6th graders are in the school

Answers

Answer:

800. Here's why:

Step-by-step explanation:

This indicats that 440 students make up 55% of the 6th grade population. We can write this as

55/440.

We also know that 'x' total students make up 100% of the 6th-grade population, so we can write this as

100/x.

55/440 must be equal to 100/x. When cross multiplied, it becomes 50x=44000. If we divided each side by 50, we'll find that x=880. Therefore, there are 800 6th graders

Answer:495

Step-by-step explanation:

440 rounds up to 450,450+450=900-the 10 we rounded so 890-440 is 450 which is half so we need to add 440 to 550 to get 990 and we half 990 to get  495 and that is your answer i think im very sorry if this is wrong btw a sixth grader did this please find out a way to reply to my comment or something like that to tell me if i am right.

Its easy... 5 and 5.04!

Step-by-step explanation:

You have to look at it properly. It says "The value of SQUARE ROOTED K."

So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.

The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that √k falls between 2.2 and 2.3

For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3

For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3

For k = 5, √5 = 2.2 3which is between 2.2 and 2.3

For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3

For k = 5.3, √5.3 = 2.302 which is not between 2.2 and 2.3

For k = 6, √6 which is not between 2.2 and 2.3

The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.

the answer is b) i think

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2
