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

2xº
3x°
xº
Answer:
x = 30°
The angles:
2x° = 60°3x° = 90°x° = 30°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:
2x° + 3x° + x° = 180°6x° = 180°x° = 30°We can replace 30° for all the angles.
The measures are:
2(30°) = 60°3(30°) = 90°1(30°) = 30°2x = 60
3x = 90
x = 30
Step-by-step explanation: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
[tex]2x+3x+x=180[/tex]Next, combine like terms
[tex]6x=180[/tex]Finally, divide both sides by 6
[tex]x=30[/tex]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
[tex]2(30)=60[/tex]3x
[tex]3(30)=90[/tex]x
[tex]30 = 30[/tex]We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.

Find the area of the circle. Round your answer to two decimal places, if necessary.
200.96 cm
Step-by-step explanation:Area of a circle: [tex]A=[/tex] [tex]\pi r^2[/tex]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]
[tex]A=(3.14)(8)^2[/tex]
[tex]A=200.96cm[/tex]
The area of a triangular piece of stained glass is 50 square centimeters. If the height (h) of the triangle is four times the base (b) how long are the height and base of the piece of stained glass?
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

What is the Lowest Value? 0, 1, 6, 7, 1 What is the Lower Quartile? 3, 1 , 1.5, 2 What is the Median? 4, 4.5, 3.5, 6, What is the Upper Quartile? 6.5, 6, 7, 4.5, What is the Highest Value? 3, 6.5, 6, 7
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
what is the absulute devtion of 16 in this data set 19 16 4 9 7
11 is the absolute devtion
set : { 19 16 4 9 7 }
total sum: 19 + 16 + 4 + 9 + 7 = 55total integers: 5absolute devtion: sum of numbers/total data sinput = 55/5 = 11Answer: 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)

Help I need the answer for w
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

Esteban has `3` kittens. According to the vet, each kitten is born with blue eyes and there is a `50\%` chance of it changing color once they reach three months. Esteban decides to run a simulation using `3` coins, where heads represent the eyes changing color.
The table shows the results of his simulation.
Estimate the probability that at least one of Esteban’s kittens will still have blue eyes at three months old.
Answer:
89%
Step-by-step explanation:
Since Esteban ran a simulation with 100 different tries, we add up all the tries that say at least one kitten will have blue eyes. This equals 89, so the answer is 89%.

What is the slope of the line that includes these two points?
A
m = 5/4
B
m = 4/5
C
m = 5
D
m = 10
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

Alexa has $520 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $342.81.
She buys 4 bicycle reflectors for $3.90 each and a pair of bike gloves for $14.51.
She plans to spend some or all of the money she has left to buy new biking outfits for $47.72 each.
Which inequality can be used to determine oo, the maximum number of outfits Alexa can purchase while staying within her budget?
NO LINKS AND NO WRONG ANSWERS
*40 Points$$$
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.
What is inequality?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".

In the graph of an inequality, the area above a dashed line through the points (−6, 4) and (2, 4) is shaded. Which inequality does this graph represent?
A. y ≥ 4
B. y ≤ 4
C. x > 4
D. y > 4
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
