The first one can be written as a fraction because it is a repeating decimal.
The second one can be written as a fraction because it is a repeating decimal.
The third one can not be written as a fraction since it is nether terminating nor repeating.
The last one can be written as a fraction since it is a terminating decimal.
Answer:
Good night sagey!!!! sleep well
I'm assuming you want to solve for z :)
By simplifying both sides of the equation, then isolating the variable.
Exact form:
z= -5/3 , - 11/3
Mixed number form:
z= −1 2/3 , −3 2/3
Let us assume that the time taken by the category 3 hurricane to travel from Cuba to Key West = X minutes
Speed of the category 3 hurricane is given as 20.88 km/hr
So the category 3 hurricane can travel 20.88 km in 1 hour.
The distance between Cuba and Key West = 145 km
Then
20.88 km is travelled by the category 3 hurricane in = 60 minutes
145 km from Cuba to Key west is travelled by the category 3 hurricane in = X minutes
So,
X = [(145 * 60)/20.88] minutes
= 416.66 minutes
= 17 hours and 36 minutes
Time taken by the category 3 hurricane to reach Key West from Cuba is 17 hours and 36 minutes.
36 feet okay it is 36 feet of the area
