Step-by-step explanation:
5 x 4.5 = 22.5 (km)
150 – 22.5 = 127.5 (km)
35 – 5 = 30 (km/h)
127.5/30 = 4.25 (h)
4.25 x 35 = 148.75 (km)
Alternatively,
Let x be the distance that he cycles.
x/35 + (150 – x)/5 = 4.5
x + 1050 – 7x = 157.5
6x = 892.5
x = 148.75
Ans : 148.75km.

For parties of six or more, a restaurant adds a 20% gratuity (or tip). Ifa
dinner bill for a large party comes to $148.25, find the total dinner bill with
tip.
Answer:
$247.37
Step-by-step explanation:
The total dinner bill with a tip for the large party is $177.90.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.
Gratuity = bill x 0.2
Gratuity = 148.25 x 0.2
Apply the multiplication operation, and we get
Gratuity = 29.65
To find the total bill, we add the gratuity to the original bill.
Total bill = bill + gratuity
Total bill = 148.25 + 29.65
Apply the addition operation, and we get
Total bill = $177.90
Hence, the total dinner bill with a tip for the large party is $177.90.

Kevin and Kenneth each earn $135 a month as a salary. They earn a commission for each sale they make, and the ratio of Kevin and Kenneth’s commission is 3:4. If they sell products worth $610 each in March, and Kevin earns a 12% commission, how much money did each of them earn?
Answer:
I don't know but this might be helpful add and multiply the numbers they give you and divide by 12%
Step-by-step explanation:
The amount of money Kevin earn = $ 232.60
The amount of money Kenneth earn = $ 207.12
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the amount of money Kevin earn = A
Let the amount of money Kenneth earn = B
Salary of Kevin = $ 135
Salary of Kenneth = $ 135
Now , the equation will be
Ratio of Kevin's and Kenneth's commission be = a : b
The value of a : b = 3 : 4
Now , Kevin earns 12 percentage commission
So , the value of a = 12 %
So , the commission earned by Kenneth b = 12 x ( 4 / 3 )
The commission earned by Kenneth b = 16 %
Now , the total amount of products sold by Kevin and Kenneth = $ 610 each
So , the commission of Kevin a = ( 12/100 ) x 610
The commission of Kevin a = $ 73.20
And , the total earning of Kevin = amount of Kevin's salary + commission of Kevin a
Substituting the values in the equation , we get
The total earning of Kevin A = 135 + 73.2
The total earning of Kevin A = 207.12
Now ,
The commission earned by Kenneth b = ( 16/100 ) x 610
The commission earned by Kenneth b = $ 97.60
The total earning of Kenneth B = amount of Kenneth's salary + commission of Kenneth b
Substituting the values in the equation , we get
The total earning of Kenneth B = 135 + 97.60
The total earning of Kenneth B = $ 232.60
Therefore , the value of A is $ 207.12 and the value of B is $ 232.60
Hence ,
The amount of money Kevin earn = $ 232.60
The amount of money Kenneth earn = $ 207.12

3 Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.
4 Mr Hill, Mrs. Jackson, Mrs. Maury, Mr. Douglas.
The order is Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given, table shows the portion of votes each candidate get,
Nominees Voting Portion
Mr. Douglas 9/50
Mrs. Maury 26%
Mr. Hill 7/20
Mrs. Jackson 0.21
converting the votes in equal ratio,
Mr. Douglas = 9/50 votes
multiply and divide by 2
Mr. Douglas = 9 x2/50 x 2 = 18/100
Mrs. Maury = 26% = 26/100
Mr. Hill = 7/20
multiply and divide by 5
Mr. Hill = 7 x 5/20 x 5 = 35/100
Mrs. Jackson = 0.21 = 21/100
Mr. Hill is winner with most number of votes.
Hence the order beginning with winner is Mr. Hill, Mrs. Maury, Mrs. Jackson, Mr. Douglas.

A data set can have more than one median? True False
Answer:
False
Step-by-step explanation:
The given statement "A data set can have more than one median" is False.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median; It represents the middle value of the given data when arranged in a particular order.
Mode; It is that number that appears most frequently in the given set of data.
Given the statement as; A data set can have more than one median.
If the value changed is not the middle value (if number of observations are odd) or is not changing the average of two mid values (if number of observations are even), then the median won't change as it does not care about the value of the data unless its about the mid value of the sorted data or average of mid values.
Since the median and mean can only have one value for a given data set. The mode can have more than one value
The given statement is False.
