Answer:
26.1 feet
Step-by-step explanation:
This question is solved using Pythagoras theorem
Pythagoras Theorem =
c² = a² + b²
c = longest side = 27 feet
One post is 12 feet tall while the other is 19 feet tall.
The vertical side = a is calculated as
19 - 12 = 7 feet.
The third side = b = how far apart they are = ?
Therefore,
27² = 7² + b²
b² = 27² - 7²
b = √27² - 7²
b = √(680)
b = 26.076809621 feet
Approximately = 26.1 feet
Therefore, the distance between the posts = 26.1 feet
If 40% or .4 of her savings is $85 then we can write the equation .4s=$85 (s being the original amount in savings)
Divide both sides by .4 to get s= $212.50 as the original amount that she had
Answer:
In the year 2010, the population of the city was 175,000
Step-by-step explanation:
If we rewrote this as a linear expression in standard form (it is linear, btw), it would look like this:

The rate of change, the slope of this line, is 11/2. If the year 2010 is our time zero (in other words, we start the clock at that year), then 0 time has gone by in the year 2010. In the year 2011, t = 1 (one year goes by from 2010 to 2011); in the year 2012, t = 2 (two years have gone by from 2010 to 2012), etc. If we plug in a 0 for t we get that y = 175,000. That is our y-intercept, which also serves to give us the starting amount of something time-related when NO time has gone by.
