Answer:
20%
Step-by-step explanation:
According to the Question,
Given that, The average number of subscribers to an online magazine each year from 2010 to 2015 is given in the table.
Year Number of Subscribers Percentage increase(20%)
2010 320000
2011 384000 320000 × 1.20 = 384000
2012 460800 384000 × 1.20 = 460800
2013 552960 460800 × 1.20 = 552960
2014 663552 552960 × 1.20 = 663552
2015 796262 663552 × 1.20 = 796262
- The percent increase in the average number of subscribers each year since 2010 was 20% .
Answer:
feet : Shark is 72 feet below sea level.
Step-by-step explanation:
Let x represent depth of the shark.
We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be 
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be 
.We can represent this information in an equation as:
To find shark's position, we need to solve for x.
Therefore, feet represents shark's elevation, which represents that shark is 72 feet below sea level.
'Miami to Orlando' = 1 1/2 hours = 1.5 hours
'Miami to Tallahassee' = 5 times of 'Miami to Orlando', then
5 * 1.5 = 7.5
So the train would take 7.5 hours or 7 1/2 hours from Mami to Tallahassee.
Answer: √51
—————————
a^2 + b^2 = c^2
a^2 + 7^2 = 10^2
a^2 + 49 = 100
a^2 = 51
√(a^2) = √51
a = √51
