2. A) 12
3. A) 11.4
4. A) 5.7
5. A) 16.2
6. A) 11.2
7. No, they do not form a right triangle
8. Yes, they do form a right triangle
Step-by-step explanation:
Extra tip: The hypotenuse has to be less than both sides added together, but cannot be more than either of the sides alone.
1.
16² + b² = 17²
256 + b² = 289
256 - 256 + b² = 289 - 256
b² = 33
√b² = √33
b = 5.74 or 5.7
2.
16² + b² = 20²
256 + b² = 400
256 - 256 + b² = 400 - 256
b² = 144
√b² = √144
b = 12
3.
7² + 9² = c²
49 + 81 = c²
130 = c²
√130 = √c²
11.40 or 11.4 = c
4.
7² + b² = 9²
49 + b² = 81
49 - 49 + b² = 81 - 49
b² = 32
√b² = √32
b = 5.65 or 5.7
5.
a² + 5² = 17²
a² + 25 = 289
a² + 25 - 25 = 289 - 25
a² = 264
√a² = √264
a = 16.24 or 16.2
6.
10² + b² = 15²
100 + b² = 225
100 - 100 + b² = 225 - 100
b² = 125
√b² = √125
b = 11.18 or 11.2
7.
15² + 8² = 16²
225 + 64 = 256
289 ≠ 256
8.
5² + 12² = 13²
25 + 144 = 169
169 = 169

The cost of the piece of granite is $137.70. What would you expect to pay for a similar piece of granite that is 108 inches by 60 inches?
Answers
Answer:
2203.20
Step-by-step explanation:
The first piece is 15 by 27 = 405 sq in. (as shown in the pic someone else posted.)
$137.70 / 405 = 34 cents per sq in\
A piece that is 108 by 60 = 6480 sq in
6480 x .34 = $2,203.20
Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
Part 2: Organize Your Data
Create a table of values using the age and number of U.S. states named in 60 seconds.
A graph is provided with the first five points plotted. Use your table to add your five data points to the scatter plot.
You may create a new graph from scratch, containing all 10 points, print the sample graph and add your data, or save the sample as an image and use a drawing program to add your data to the image. If you choose to print and draw by hand, you need to be able to scan and upload your work at the end of the project.
A coordinate plane is shown. The x axis is labeled age in years and the y axis is labeled number of U.S. States named in 60 seconds. Five data points are already plotted on the graph. These points are located at 5 comma 7, 15 comma 42, 25 comma 49, 35 comma 35, and 65 comma 50.
Draw a line of best fit through your scatter plot. Draw by hand on your printed graph or use a drawing program on your computer to create the line.
Part 3: Drawing Conclusions
How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Answers
So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

A circular placemat has 44 inches of braid around the edge. What is the area of the placemat to the nearest square inch? Use 3.14 for π.
Enter the correct answer in the box.
[ ]
Answers
==========================================================
Explanation:
We'll need to use the circumference formula
C = 2*pi*r
to find the value of the radius r when C = 44
So we get
C = 2*pi*r
44 = 2*3.14*r
44 = 6.28*r
6.28r = 44
r = 44/6.28
r = 7.0063694267516
which is approximate
Then we use this value of r to find the area we need
A = pi*r^2
A = 3.14*(7.0063694267516)^2
A = 154.140127388536
A = 154
The area of the circular placemat is approximately 154 square inches.
Answer:
a ~ 154
a = \(\frac{484}{(pi)}\)
Step-by-step explanation:
1. Approach
In this problem, one is given the circumference, the distance around the circle, one must find the area. In order to find the area, one must know the radius of the circle. To find the radius, one has to backsolve from the given circumference, then substitute the derived value into the formula for the area and solve.
2. Find the radius
The formula to find the circumference of a circle is;
\(2r(pi)=c\)
Where (r) is the radius, (pi) is (3.1415), and (c) is the circumference.
Substitute in the given values and solve;
\(2r(pi) = c\\2r(pi) = 44\\r=\frac{44}{2(pi)}\\r=\frac{22}{(pi)}\)
3. Find the area
Now, one has the value of the radius, substitute it into the formula for the area of a circle and solve;
The formula for finding the area of a circle;
\((pi)r^{2}=a\)
Where (pi) is (3.1415), (r) is the radius, and (a) is the area,
Substitute in the value and solve.
\((pi)r^{2} = a\\(pi)(\frac{22}{(pi)})^{2}=a\\\frac{(22)^{2}}{(pi)}=a\\\frac{484}{(pi)}=a\)
a ~ 154
How do we find percent of increase
Answers
Answer:
See explanation and example below.
Step-by-step explanation:
To find percent increase you must know the original amount and the new amount. Then use the formula below:
percent increase = (new amount - old amount)/(old amount) × 100%
Example:
A book used to cost $10. Then the price increased to $12. What is the percent increase?
Given information:
old amount = $10
new amount = $12
Percent increase formula:
percent increase = (new amount - old amount)/(old amount) × 100%
Apply the given information to the formula:
percent increase = ($12 - $10)/($10) × 100%
percent increase = $2/$10 × 100%
percent increase = 0.2 × 100%
percent increase = 20%
Answer: The percent increase from $10 to $12 is 20%.
Answer:
Increase = Increase / The original Number * 100
Step-by-step explanation:
Don't worry I gotchu!
You basically divide the amount that is progressing, i.e, or that is, the increase of the number by the original number and then multiply by 100. SO thats how you find the percent of increase! Sry if i stated another formula but i think it is the right one. sry if i am wrong :(

Answer:
Step-by-step explanation
So I divided the figure into two the triangle was separate from the rectangle. Then I multiplied the sides of the rectangle 10 times 8 and got 80 and since there are two sides I timed that by two. Then the front and the back and got 256 and timed that by two. Then the bottom and the top and got 320 and also timed that by two then I added those up. Next I worked on the triangle and timed the from and the back and timed 12 and 20 then divided it by 2 because its a triangle and got 120 and since there was another one I timed it by 2. Then came the sides and I timed 20 and 10 then divided it by 2 and timed it by 2 since there were two sides then I added those with the rectangle and got my answer.
Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.
