Answer:

22 km

Step-by-step explanation:

There is no mention about the triangle, but this can only be solved if the triangles are similar.

I assume the triangles are similar, so the lengths of corresponding sides are proprtional.

PR/TR = PQ/ST

24/33 = 16/ST

8/11 = 16/ST

1/11 = 2/ST

ST = 22

Answer: 22 km

20kg is the answer Iopiikjuj

11 is the absolute devtion

set : { 19 16 4 9 7 }

Answer:  5.

Reasoning: How you get the absolute deviation of a number in a set is to

1. Find the median (add all the numbers together, then divide it by the amount of numbers) (19+16+4+9+7=55, then 55 divided by 5 to get 11)

2. Find the difference between the number (16 in this case) and the median (11) (16-11=5)

Answer:A. y ≥ 2

Step-by-step explanation:

First the line is solid, a complete line not dotted so the inequality sign to use is : ≥  or ≤

The points have their y-coordinate vale as 2, (−5, 2) and (3, 2), this means the line crosses the y-axis at y=2 but because the shaded part is above this line, then the correct inequality will be :

y ≥ 2

Answer:

y = -6.17

Step-by-step explanation:

Answer:

3 outfits with $3.92 as change

Step-by-step explanation:

The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

Bicycle cost = $342.82

4 bicycle reflectors cost = 4 × 3.90 = $15.6

Gloves cost = $14.51

Cost of "o" biking outfit = 47.72o.

Total cost ≤ Budget.

342.82 + 15.6 + 14.51 + 47.72o ≤ 520

372.92 + 47.20 o ≤ 520

520 ≥ 47.20o + 372.92

Hence "The inequality represents the maximum number of outfits Alexa can purchase while staying within her budget is 520 ≥ 47.20o + 372.92".

Answer:

Height = 20 ; Base = 5

Step-by-step explanation:

Triangle Area = Base x Height x 1/2

50 = 1x × 4x × 1/2

50 = 4x^2 × 1/2

50 = 2x^2

25 = x^2

x=5

Height equals to 4x -> 4 × 5 = 20

Base equals to x -> 1 × 5 = 5

Answer:

x = 30°

The angles:

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

We can replace 30° for all the angles.

The measures are:

2x = 60

3x = 90

x = 30

All triangles have 3 angles that add up to 180 degrees. We can use the information to create an equation.

Finding x

First, add all of the angles together and set them equal to 180

Next, combine like terms

Finally, divide both sides by 6

Solve For Missing Angles

Now that we have x, we can solve from each of the missing angles. Do this by plugging in 30 for the x-values.

2x

3x

x

We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.

Answer:

[tex]\huge\boxed{\sf w = -14}[/tex]

Step-by-step explanation:

Given Equation:

6 + w = -8

Subtract 6 to both sides

w = -8 - 6

w = -14

[tex]\rule[225]{225}{2}[/tex]

Answer:

w = -14

Step-by-step explanation:

6 + w = -8

move 6 to the other side of the = sign

to do that you must subtract from both sides (of the equal sign) it since it is a positive number

6 + w = -8

-6          -6

this makes the 6 cancel out

-8 - 6 = -14

w = -14

your answer is -14

Step-by-step explanation:

200.96 cm

Since we don't have the radius, we have to find it.

What you gave me is the diameter which is 16 (cm) I suppose.

Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.

[tex]16[/tex] ÷ [tex]2=8[/tex]

This is our radius.

Plug this into the area formula.

[tex]A=\pi r^2[/tex]

Answer:

lowest value-0

lower quartile(or first quartile)-1.25

median-4.25

upper quartile-6.75

highest value-7

Step-by-step explanation:

lowest value=is the lowest number of a set

lower quartile(first quartile)=the number between the median and th   minimum or if there is a  even amount of values you find the mean of the values between the minimum and maximum

median=the middle number of a set

upper quartile(third quartile)=the middle number between the median and the maximum.

highest value(maximum)=the highest number in the set

Answer:

Lowest Value = 0

Lower Quartile = 1.5

Median = 4.5

Lower Quartile = 6.5

Highest Value = 7

Step-by-step explanation:

Given values:  

0, 1, 2, 3, 6, 6, 7, 7

Before determining the quartiles, place the values of the data set in order of size.

To find the position of the lower quartile (Q1) first work out n/4 (where n is the number of data values in the set).

If n/4 is a whole number, then the lower quartile is halfway between the values in this position and the position above.

⇒ 8/4 = 2, so the Lower Quartile is halfway between the 2nd and 3rd values.

⇒ Lower Quartile = 1.5

The median is the value in the middle of the data set when all the data values are placed in order of size.

To find the position of the median (Q2) first work out n/2.

If n/2 is a whole number, then the median is halfway between the values in this position and the position above.

⇒ Median = 4.5

To find the position of the upper quartile (Q3) first work out 3n/4 (where n is the number of data values in the set).

If 3n/4 is a whole number, then the lower quartile is halfway between the values in this position and the position above.

⇒ (3 x 8)/4 = 6, so the Lower Quartile is halfway between the 6th and 7th values.

⇒ Lower Quartile = 1.5

The lowest value is the smallest value in the data set = 0

The highest value is the largest value in the data set = 7

Answer: D. 61 in²

Step-by-step explanation:

     This problem is asking for us to solve the area of the given circle. We will use the formula and solve.

     Please note that the formula asks for the radius and 9 in is the diameter. Since the radius is half the diameter, we will divide 9 in by 2 for a radius of 4.5 in.

     A = πr²

     A = π(4.5 in)²

     A ≈ 63.62 in²

     The closest option they give to solve this problem is D. 61 in²

          About 61 in² of pie crust is needed to cover the top of the pie.

Answer: How to Calculate Slope of a Line

Calculate slope, m using the formula for slope:

Slope Formula

m=(y2−y1)(x2−x1)

m=riserun=ΔyΔx=y2−y1x2−x1

Here you need to know the coordinates of 2 points on a line, (x1, y1) and (x2, y2).

How to Find Slope of a Line

Find the difference between the y coordinates, Δy is change in y

Δy = y2 - y1

Find the difference between the x coordinates, Δx is change in x

Δx = x2 - x1

Divide Δy by Δx to find slope

m = Δy/Δx

Example: Find the Slope

Say you know two points on a line and their coordinates are (2, 5) and (9, 19). Find slope by finding the difference in the y points, and divide that by the difference in the x points.

The difference between y coordinates Δy is

Δy = y2 - y1

Δy = 19 - 5

Δy = 14

The difference between x coordinates Δx is

Δx = x2 - x1

Δx = 9 - 2

Δx = 7

Divide Δy by Δx to find slope m

m=142

m=7

Line Equations with Slope

There are 3 common ways to write line equations with slope:

Point slope form

Slope intercept form

Standard form

Point slope form is written as

y - y1 = m(x - x1)

Using the coordinates of one of the points on the line, insert the values in the x1 and y1 spots to get an equation of a line in point slope form.

Lets use a point from the original example above (2, 5), and the slope which we calculated as 7. Put those values in the point slope format to get an equation of that line in point slope form:

y - 5 = 7(x - 2)

If you simplify the point slope equation above you get the equation of the line in slope intercept form.

Slope intercept form is written as

y = mx + b

Take the point slope form equation and multiply out 7 times x and 7 times 2.

y - 5 = 7(x - 2)

y - 5 = 7x - 14

Continue to work the equation so that y is on one side of the equals sign and everything else is on the other side.

Add 5 to both sides of the equation to get the equation in slope intercept form:

y = 7x - 9

Standard form of the equation for a line is written as

Ax + By = C

You may also see standard form written as Ax + By + C = 0 in some references.

Use either the point slope form or slope intercept form equation and work out the math to rearrange the equation into standard form. Note that the equation should not include fractions or decimals, and the x coefficient should only be positive.

Slope intercept form: y = 7x - 9

Subtract y from both sides of the equation to get 7x - y - 9 = 0

Add 9 to both sides of the equation to get 7x - y = 9

Slope intercept form y = 7x - 9 becomes 7x - y = 9 written in standard form.

Find Slope From an Equation

If you have the equation for a line you can put it into slope intercept form. The coefficient of x will be the slope.

Example

You have the equation of a line, 6x - 2y = 12, and you need to find the slope.

Your goal is to get the equation into slope intercept format y = mx + b

Start with your equation 6x - 2y = 12

Add 2y to both sides to get 6x = 12 + 2y

Subtract 12 from both sides of the equation to get 6x - 12 = 2y

You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6

This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3

How to Find the y-Intercept

The y-intercept of a line is the value of y when x=0.  It is the point where the line crosses the y axis.

Using the equation y = 3x - 6, set x=0 to find the y-intercept.

y = 3(0) - 6

y = -6

The y-intercept is -6

How to Find the x-Intercept

The x-intercept of a line is the value of x when y=0.  It is the point where the line crosses the x axis.

Using the equation y = 3x - 6, set y=0 to find the x-intercept.

0 = 3x - 6

3x = 6
