In expanded form that would be:
500,000 + 70,000 + 20
Hope that helps :)
71% water
29% land
71:29= 2,448=> the amount of earth surface that is covered with water is ~2,5 times bigger than the amount of earth surface that is covered with land

Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.
Step-by-step explanation:
A circular running track 1/4 is a mile long.
Elena runs on this track, completing each lap in 1/20 of an hour.
Speed formula is used to determine the speed of Elena. The formula of speed is given by:
----- (1)
where S is the speed, D is the distance and T is the time taken by Elena to run a circle.
Now, put the value of distance D and time T in the equation (1).
Speed = 5 miles/hour
Therefore, the running speed of Elena is 5 miles/hour.

Answer:
m=-1/6
Step-by-step explanation:
The slope equation is m=(y₂-y₁)/(x₂-x₁)
For this problem
y₂=-5
y₁=0
X₂=32
x₁=2
Then applying the equation
m=(-5-0)/(32-2)
m=(-5)/(30)
m=-1/6
m=-0,167
The negative means the slope is decreasing
