Answer:
A. 27.50 = 5.50 + 2.75h
B. 8 hours
C. 9 hours
Step-by-step explanation:
Total spent = $27.50
Base fee = $5.50
Hourly rate = $2.75
A. Create an equation that can be used to determine how many additional hours, ℎ, Rose parked her car in the garage
Total cost = fixed cost + variable cost
27.50 = 5.50 + 2.75h
B: Solve the equation to determine the number of additional hours, ℎ, Rose parked her car in the garage.
27.50 = 5.50 + 2.75h
Subtract 5.50 from both sides
27.50 - 5.50 = 5.50 - 5.50 + 2.75h
22 = 2.75h
Divide both sides by 2.75
h = 22/2.75
= 8
h = 8 hours
C: What is the total number of hours that Rose parked her car in the garage
Total number of hours = first hour + additional hours
= 1 + 8
= 9 hours
Answer:
A. Integers
Step-by-step explanation:
Subtraction of whole or natural numbers can result in a negative number that is not in the set. Subtraction of irrational numbers can result in a rational number (√2 -√2 = 0, for example).
There are 10 possible numbers. 111 is one of the numbers. The probability is 1/10 or 0.1.
There are two numbers that are smaller than 107. The probability is 2/10 or 0.2.
**Side note**: Computers actually are not random, they are pseudorandom. They are very close to random, but not quite. However this will not affect the answer.
Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation
is similar to equation of line
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
