at bike shop x it costs $2.75 per hour plus a $3.00 deposit to rent a bike. at bike shop z it costs $1.75 per hour plus a $7.00 deposit to rent a bike.
a.) write the system of equations that could be used to find c, the total cost for renting a bike for n hours at each shop.
b.) graph the system of equations.
c.) when would it cost less to rent a bike from bike shop x? explain.
Answers
Answer:
Multiply the rate per hour by the number of hours (n) and add the deposit.
A)
Bike shop x: c = 2.75n + 3.00
Bike shop z: c = 1.75n + 7.00
B) to find when they will cost the same set the equations equal to each other and solve for n:
2.75n + 3.00 = 1.75n + 7.00
Subtract 3 from each side:
2.75n = 1.75n + 4.00
Subtract 1.75n from both sides:
1.00n = 4.00
Divide both sides by 1:
n = 4 hours

The formula for the volume of a cylinder is V=\(\pi r^{2} h\)h, where V is the volume, r is the length of the radius of the base, and h is the height of the cylinder.
Answers
Answer: The volume for a cylinder is pi times radius squared multiplied by height. If the radius for the base of a cylinder is 2 inches, and its height is 8 inches, we square our radius 2 and get 4. Then we multiply this by pi which would be 3.14, to get 12.56. Then we multiply the product by height (8), 12.56 times 8, is 100.48 inches which is the volume of the cylinder.
Step-by-step explanation:
The formula to calculate the volume of a cylinder is:
\(\boldsymbol{\sf{V=\pi r^{2}h }}\), where
V = VolumeR = radiusH = Heightπ = PThe cylinder has radius and height.
To calculate the volume, we substitute the data in the formula, which are the radius and the height.
First calculate the radius squared. Then the value of PI is multiplied, which the value is 3.14 by the radius in cm^2 by the height. And in this way the volume of the cylinder will be calculated.
John currently has $500 in his lunch account. He spent $15 each day on lunch. In how many days will John have $245?
Answers
Answer:
18 days.
Step-by-step explanation:
Step 1) Building an arithmetic sequence
We can build an arithmetic series with the given information.
The \(n\)th term of an arithmetic series is given by the formula \(a_n = a_1 + (n - 1)d\) .
\(a_1 = 500\\d = -15\\\to a_n = 500 - 15(n - 1) = 515 - 15n\)
Step 2) Finding the n for which a(n) = 245
As this step's title implies, we need to solve the equation \(a_n = 245\):
\(515 - 15n = 245 \text{ / Subtract 245}\\515 - 15n - 245 = 245 - 245\\\to 270 - 15n = 0 \text{ / Add 15n}\\270 - 15n + 15n= 0 + 15n\\\to 270 = 15n \text{ / Divide by 15}\\\frac{270}{15} = \frac{15n}{15}\\\to 18 = n\)
John will have $245 in 18 days.
Answer:
17 days
Step-by-step explanation:
Since John starts with $500 and each day, he’ll spend $15 on lunch. This means that:
On his first day, he’ll spend $15.On his second day, he’ll spend another $15 which is total spend of $30 ($15 x 2)On his third day, he’ll spend total of $45 ($15 x 3)Therefore, on his nth day, he’ll spend $15n where n represents the day. The problem can be modeled into an equation of \(\displaystyle{500-15n=245}\) since we will be finding how many days it will take to reach $245.
Then solve for n-term which we determines as the day variable:
\(\displaystyle{500-15n-245=0}\\\\\displaystyle{255-15n=0}\\\\\displaystyle{255=15n}\\\\\displaystyle{n=17}\)
Therefore, on his 17th day, he’ll have $245. Hence, the answer is 17 days.

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

During a 20% off sale, the sale price of a microwave was $60. The sale has expired but Kristen has a coupon good for 15% off the regular price of any one item. How much will Kristen pay for the microwave before tax? Round to the nearest cent.
Answers
Answer:
it would take 9 dollar OFF!! so subtracted by 60 your welcome!!
(its 51 just saying.)
Step-by-step explanation:
x - 0.2x = 60
Simplifying the left side, we get:
0.8x = 60
Dividing both sides by 0.8, we get:
x = 75
So the regular price of the microwave is $75. Now, we can use Kristen's coupon to find the price she will pay:
Regular price = $75
Discount from coupon = 15%
Amount of discount = 0.15 x $75 = $11.25
Subtracting the discount from the regular price, we get:
Price after coupon = $75 - $11.25 = $63.75
Therefore, Kristen will pay $63.75 for the microwave before tax.
A student claims that 50% of a sample of data is less than the median and 50% of data is greater than the median, therefore the data is symmetric. What is the student's error?
a) The student did not make an error
b) It is impossible for 50% of the data values to be both less than and greater than the median, so you can't determine whether or not the data is symmetric.
c) While 50% of the data values are always greater than the median, the data may have greater variability on one side of the median than the other.
d) Data is never symmetric, so this assumption is incorrect.
Answers
Answer:
A
Step-by-step explanation:
Simply put if it's 50-50 then it just is what it is
The student's error is that d) Data is never symmetric, so this assumption is incorrect.
What is Median?Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given that,
A student claims that 50% of a sample of data is less than the median and 50% of data is greater than the median, therefore the data is symmetric.
In a symmetric distribution, the left hand side and the right hand side of the median will be equal.
That is, the left points and the right points are equal.
Hence the correct option is d) Data is never symmetric, so this assumption is incorrect.

Here is a scale drawing of a garden. Kim wants to plant a tree in the garden according to the following rules: It must be 7 m from A and 4 m from C. Place a cross where Kim can plant the tree.
Answers
Answer:
If the scale is 1 or more cm to every meter you can count 7 from A
if it is 2cm to every meter you can count 6cm and count this as 3 meter so that when you extend another 6cm you have 3m +3m = 6 meters it would just be 2 more cm to count for 1 m to equal it has 7m.
Repeat for 4m for C which is 4 groups of cm depending what the scale is.
The two should meet at a cross the same as counting one direction from 7 and counting across for 4 in another direction.
Step-by-step explanation:
On the scale drawing of the garden, the point to plant the tree is 3.5cm from point A and 2cm from point C
The scale factor is given as: 1 cm represents 2 m
From the question, we understand that the point to plant the tree is 7m from point A and 4 m from point C
Using the scale factor, the location of the point is calculated as follows:
\(\mathbf{A = \frac{7cm}{2}}\)
\(\mathbf{A = 3.5cm}\)
\(\mathbf{C = \frac{4cm}{2}}\)
\(\mathbf{C = 2cm}\)
This means that the point is 3.5cm from point A and 2cm from point C
