3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
Answer: 0.3125 hours
Step-by-step explanation:
The formula for time taken to cover a distance is:
= Distance / Speed
Distance = 2.5 miles
Speed = 8 miles per hour
Time taken = 2.5 / 8
= 0.3125 hours
In minutes this is:
= 0.3125 * 60 mins
= 19 mins approx
Answer:
31.76 ft and 58.64 ft
Step-by-step explanation:
The radius measures between 13 feet and 24 feet.
The wheel is able to turn 7π/9 radians before getting stuck.
We need to find the range of distances that the wheel could spin before getting stuck. That is, the length of arc.
Length of an arc is given as:

where θ = central angle = 7π/9 radians
r = radius of the circle
Therefore, for 13 feet:

For 24 feet:

The wheel could spin between 31.76 ft and 58.64 ft before getting stuck.
