Answer:
254.34 cm²
Step-by-step explanation:
A = πr2 Use the formula.
A = π(9)2 Substitute. Use 9 for r.
A ≈ 3.14 × 92 Substitute. Use 3.14 for π.
A ≈ 3.14 × 81 Evaluate the power.
A ≈ 254.34 Multiply.

Each month Javier takes his recycling to the local recycling center where he separates the glass bottles into different
colors. He would like to determine the proportion of glass his household recycles that is clear glass, so he mixes up
his container and randomly grabs 10 glass items and determines the proportion that are clear glass.
The population is
The sample is
The parameter is the proportion of
The statistic is the proportion of
Answer:
The population is: all glass recycled
The sample is: the 10 selected glass items.
The parameter is the proportion of: all his glass that is clear
The statistic is the proportion of: the selected glass that is clear
The population of a distribution is the entire group, while the sample is the selected group from the entire group.
The population is all glass recycled The sample is the 10 selected glass items. The parameter is the proportion of all his glass that is clear The statistic is the proportion of the selected glass that is clearThe population
From the question, we understand that glasses are recycled and then separated into colors.
This means that, the population is all glass recycled
The sample
From the question, we understand that he randomly grabs 10 glass items, and then determine the proportion of clear glasses.
This means that, the sample is the 10 selected glass items.
The parameter
This is the value that summarizes all the glasses that are being recycled.
So, the parameter is the proportion of all his clear glasses
The statistic
This is the value that summarizes the selected glasses.
So, the statistic is the proportion of the selected glass that is clear

Mr. Shaw wants to replace the flooring his family room. The floor has an area of 262.8 square feet. If the room is 18 feet long, how wide is it? Justify your procedure.
Answer:
14.6
Step-by-step explanation:
The area of a rectangle is area=length*width
so we can substitute the numbers here, 262.8=18w
divide 262.8 by 18 to isolate the variable.
You get 14.6.
The width is 14.6.

Find the measure of each angle indicated. Show work.
Answer:
? = 109 degrees
Step-by-step explanation:
45 + 75 + _ = 180 ( look for vertical angles)
45 + 75 + 60 = 180
60 +79 + _ = 180 (look for a straight line that forms 180 degrees)
60 + 79 + 41 = 180
68 + 41 + _ = 180 (look for a triangle that adds up to 180)
68 + 41 + 71 =180
180 - 71 = 109 (look for a linear pair)

6x-18=54 what does the x represent
Answer:
x=12
Step-by-step explanation:
I attached a picture for the steps
Simplifying
6x + -18 = 54
Reorder the terms:
-18 + 6x = 54
Solving
-18 + 6x = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 6x = 54 + 18
Combine like terms: -18 + 18 = 0
0 + 6x = 54 + 18
6x = 54 + 18
Combine like terms: 54 + 18 = 72
6x = 72
Divide each side by '6'.
x = 12
Simplifying
x = 12
Final Result: 12

Answer: D.) y = 2x + 1
Step-by-step explanation:
in slope-intercept form, y = mx + b, m is the slope, Rise/Run
The difference in y-values, rise, increases by 2 for every increase of 1 in x-values, the run.
2/1 is the slope
m = 2
b is the y-intercept
To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:
9 = 4(2) + b
9 = 8 + b
1 = b
Rewrite the equation with the values calculated for m and b. Keep y and x
y = 2x + 1
