The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm
Answer:
girlllllllll let me work it out lol
Step-by-step explanation:
Answer:
The population density (people per square mile) for the country is 5 person per square mile.
Step-by-step explanation:
Given:
Population of the country = 34,782,000
Area of the country = 7,539,000
To Find:
The population density of the country = ?
Solution:
The population density is the number people per square mile.
The population density can be found by

On Substituting the values
population density = 
Population density = 4.61
Population density = 5
We have a large numer and using scientfic notation is a great way to break down the number. So let's break it down!
1,000 x 1 = 1,000
3 x 100 = 300
6 x 10 = 60
3 x 1 = 3
So the form for scientific notation is a x 10b and we need to convert it into decial form.
1,360 becomes 1.36 (forget the 0) for a. 10 b is 103
1.36 x 103. Notation will always have a square. Our b.
10^3
SO, now we have
1.36 x 10^3 = 1,360
