Answer:
see the attached graph
Step-by-step explanation:
The axes and units for the graph are given in the problem statement. The range of the graph is also given, but figuring the domain requires a little arithmetic. We assume the walking pace is constant, so the graph will be piecewise linear.
The vertical (y) axis is labeled with what the graph is modeling, "distance from home (in meters)." The horizontal (x) axis is labeled with what the model is in terms of "time (in minutes)."
The range of the graph is 0 to 400 meters, the range of distances Sam may be from home.
The domain of the graph is 0 to 9 minutes. The time it takes to complete the trip is 4 minutes to the shop, 2 minutes at the shop, and 3 minutes coming home, for a total of 4+2+3 = 9 minutes.
We are given that points on the graph will be (0, 0), (4, 400), (6, 400), and (9, 0). That is Sam is ...
Since we assume walking is at a steady pace, we connect these dots with straight lines. The resulting graph is attached.
The original price of the item is given by the equation A = $ 93.75
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 original price of the item be represented as A
Now , the equation will be
The discount percentage of the item = 20 %
The discounted sale price of the item = $ 75
So , original price - ( 20/100 ) original price = discounted price
Substituting the values in the equation , we get
A - ( 20/100 )A = 75
( 80/100 )A = 75
Multiply by 100 on both sides of the equation , we get
80A = 7500
Divide by 80 on both sides of the equation , we get
A = $ 93.75
Hence , the original price is $ 93.75

Step-by-step explanation:
Answer:
60mins/1 hour
Step-by-step explanation:
The student made an error by skipping the necessary step of converting hours to minutes before converting to minutes to seconds. The correct conversion is: 15 hours is equal to 54000 seconds.
In mathematics, specifically in units conversion, the correct step to convert hours to seconds would be to first convert the hours to minutes, and then convert minutes to seconds. The mistake the student made was skipping the step of converting hours to minutes before converting to seconds. Let's correct the calculation:
So, 15 hours is equal to 54000 seconds, not 900 seconds.
