Answer: 0.49 dollars, which is equivalent to 49 cents
==========================================================
Work Shown:
Divide the total cost over the number of items to get the unit cost
unit cost = (total cost)/(number of items)
unit cost = (1.47)/(3)
unit cost = 0.49 dollars
unit cost = 49 cents
---------------------------
Another approach:
3 oranges = 1.47 dollars
3/3 oranges = 1.47/3 dollars
1 orange = 0.49 dollars
1 orange = 49 cents
The unit cost is the cost of 1 item, so the the unit cost is 49 cents per orange.
The unit cost of an orange in this case is calculated by dividing the total cost ($1.47) by the number of units (3), which gives us a unit cost of approximately $0.49.
The unit price can be calculated by taking the total price and dividing it by the number of units. In this case, the total price is $1.47 and there are 3 oranges. So the unit price would be calculated as follows:
$$1.47 divided by 3 = $0.49 (rounded to the nearest cent)
Therefore, the unit cost of an orange is approximately $0.49..

Answer:
Frank can park 8.9 hours at the highest
Step-by-step explanation:
Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.
From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.
Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x
By adding this to the initial $2, we have the total $9.90
So, mathematically;
2 + x = 9.90
x = 9.9 -2
x = 7.9 hours
Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours

b) frequency
c) peak
d) amplitude
Answer: a) period
Step-by-step explanation:
a) Period is defined as the time it takes two successive crests of an ocean wave to pass a given point. It is measured in seconds.
b) Frequency is defined as the number of waves cycles that pass a point in a given time. It is measured in Hertz.
c) Peak is the highest point on the wave.
d) Amplitude is the distance between the rest position to a crest or a trough. It is measured in meters.
Translating the phrases into algebraic equation, peter's number would be: 29.
Let the unknown value be variable x, then translate the phrases given into algebraic expressions and solve for the unknown variable.
Let Peters number be x
-6(x - 14) = -90
Solve for x
-6x + 84 = -90
-6x = -90 - 84
-6x = -174
x = 29
Therefore, translating the phrases into algebraic equation, peter's number would be: 29.
