Answer:Hint:
the remainder is 2.
Step-by-step explanation:
23≡1 mod 7 and 33≡−1 mod 7.
Edit: The only thing you need from the modular arithmetic is that
a⋅b mod 7=(a mod 7)(b mod 7) mod 7,
meaning the remainder of a product is the remainder of the product of remainders. This is self-evident as a⋅b must have the same remainder as (a−7k)⋅(b−7l).
Since exponentiation is just repeated multiplication, we can write
230⋅320=(23)10⋅(33)6⋅32≡110⋅(−1)6⋅9=9

25x + 15 ≥ 395
A Susan needs to save up enough money to repair her car. She has already saved $25 and can save another $15 per week. How many weeks will it take for Susan to save enough for auto repairs?
B James has his eye on a new stereo. The one he really wants is $395. James has already saved $15 and can save an additional $25 per week. How many weeks (x) will it take for him to save enough to purchase the stereo?
C Susan needs to save up enough money to repair her car. She has already saved $15 and can save another $25 per week. How many weeks will it take for Susan to save enough for auto repairs?
D James has his eye on a new stereo. The one he really wants is $395. James has already saved $25 and can save an additional $15 per week. How many weeks (x) will it take for him to save enough to purchase the stereo
Answer: B
Step-by-step explanation: James needs $395 or more, so it can't be A or D because those problems don't mention 395$. B is saying that he already has $15, and can save 25$ per week, (x represents the number of weeks) while D is saying he already has 25$ and can save 15$ per week.

Step-by-step explanation:
First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.
Question 17
Using a calculator, you get 6.48074069… for your decimal.
Rounding it to the nearest tenth, your answer would be 6.5
Now, to find the two consecutive whole numbers the square root is between…
However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.
Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!
Question 18
Using a calculator, you get 9.380833151… for your decimal.
This rounds to 9.4
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.
In non-decimal form (simplified radical), your answer can be 2√22.
Question 19
Using a calculator, you get 7.93725393… for your decimal.
This rounds to 7.9
The whole numbers surrounding this decimal are 7 and 8.
You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.
In non-decimal form (simplified radical), your answer can be 3√7.
Question 20
Using a calculator, you get 8.66025403… for your decimal.
This rounds to 8.7
The whole numbers surrounding this decimal are 8 and 9.
You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.
In non-decimal form (simplified radical), your answer can be 5√3.
Question 21
Using a calculator, you get 5.47722557… for your decimal.
This rounds to 5.5
The whole numbers surrounding this decimal are 5 and 6.
You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.
Question 22
Using a calculator, you get 9.84885780… for your decimal.
This rounds to 9.8
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.
Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.
Hope that helps! <3

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Compare the data and use the correct measure of center to determine which team typically has the tallest players. Explain your answer.
The Allstars, with a mean of about 67.1 inches
The Champs, with a mean of about 66.4 inches
The Allstars, with a median of about 68 inches
The Champs, with a median of about 67 inches
Answer:
45
Step-by-step explanation:
The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.
Using Mean and Median to Decide the Tallest TeamBy using mean and median, we can know which team typically has the tallest players
For the Allstars:
Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:
Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches
Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:
Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73
Median = 68 inches
For the Champs:
Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:
Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches
Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:
Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75
Median = 67 inches
The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.

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.
Trolls will be reported
Answer: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 area of a circle is 64π in². What is the circumference, in inches? Express your answer in terms of \piπ.
Answer:
8
Step-by-step explanation:
The area of a circle is \(\pi\)r²
So we can divide 64\(\pi\) by \(\pi\) and have 64.
Now take the square root of 64 and its 8
Answer:
the is 16 pie
Step-by-step explanation:
To find the circumference, we would use the formula:
\color{green}{C}=
C=
\,\,2\pi\color{red}{r}
2πr
Circumference of a Circle formula
But we don't know the radius yet. We do know the area, so we can use the area formula to find the radius:
\color{purple}{A}=
A=
\,\,\pi \color{red}{r}^{2}
πr
2
Area of a Circle formula
\color{purple}{64\pi}=
64π=
\,\,\pi \cdot \color{red}{r}^{2}
π⋅r
2
Substitute given circumference into formula
\frac{\color{purple}{64\cdot \pi}}{ \pi}=
π
64⋅π
=
\,\,\frac{\pi \cdot \color{red}{r}^{2}}{\pi}
π
π⋅r
2
Since \piπ is on both sides, divide both sides by \piπ
64=
64=
\,\,\color{red}{r}^{2}
r
2
Cancel out the \piπs from the top and bottom of each fraction.
\color{red}{r}=
r=
\,\,8
8
Squared means something times itself. What times itself equals 64?
\text{The \color{red}{radius} of the circle is \color{red}{8} feet.}
The radius of the circle is 8 feet.
\text{Now use the radius to find the circumference:}
Now use the radius to find the circumference:
\color{green}{C}=
C=
\,\,2\pi\color{red}{r}
2πr
Circumference of a Circle formula
\color{green}{C}=
C=
\,\,2 \cdot \pi \cdot\color{red}{8}
2⋅π⋅8
Substitute radius into formula
\color{green}{C}=
C=
\,\,2 \cdot\color{red}{8}\cdot \pi
2⋅8⋅π
Commutative property of multiplication
\color{green}{C}=
C=
\,\,16\pi
16π
Final answer in terms of \piπ
\text{The \color{green}{circumference} of the circle is 16\(\pi\) ft.}
The circumference of the circle is 16π ft.
Write the equations of each line in slope-intercept form. (y=mx+b)
Answer:
The equation would be y = -2x + 19
Step-by-step explanation:
To find this, we can use the point and the slope in point-slope form. The we solve for y.
y - y1 = m(x - x1)
y - 7 = -2(x - 6)
y - 7 = -2x + 12
y = -2x + 19
The case of 12 bottles of shampoo holds a total of 126 ounces. If each bottle of shampoo contains the same amount, which represents the total volume of shampoo in ounces, y, of any number of bottles, x?
12 y = 126
y = (StartFraction 12 Over 126 EndFraction) x
Volume of Shampoo
On a coordinate plane, the x-axis is labeled number of bottles and the y-axis is labeled total volume (in ounces). A line goes through points (1, 10) and (4, 42).
Volume of Shampoo
On a coordinate plane, the x-axis is labeled number of bottles and the y-axis is labeled total volume (in ounces). A line goes through points (1, 10) and (40, 3.8).
Answer : y = 10.5x y = (126/12) * x or choose the third
Step-by-step explanation: Since each bottles
are Same volume → y = ax . a = (12b)/12 = 10.5 so it's y = 10.5x or y = (126/12) * x (1) (2) are false 13) (the graph) is the
same with y = 10.5x
