Slope of this line is given by:
<em>Aaron’s rate for mowing lawns is 0.5 acres per hour</em>
Step-by-step explanation:
It is given that time is tracked by Aaron related to x coordinate.
and the area of land mowed in acres is related to y coordinate.
Two of his points are given as:
(3, 1.5) and (5,2.5)
We know that the coordinates are represented in the form of (x,y)
i.e. first coordinate represents x coordinate and
second coordinate represents y coordinate.
So, it can be observed that:
Change in x coordinate =
i.e. total time taken is 2 hours.
Change in y coordinate =
i.e. total land mowed taken is 1 acre.
In other words, <em>it takes 2 hours for Aaron to mow 1 acre of land.</em>
So, "option 1) It takes Aaron about 1 hour to mow 2 acres." is incorrect.
<u>Rate of mowing</u> lawn is the <em>land mowed by Aaron in 1 hour</em>.
Land mowed in 2 hours = 1 acre
Land mowed in 1 hours = acre i.e. 0.5 acre
Also, slope of a line is given as:
Here
As per formula:
So, option 2) Aaron’s rate for mowing lawns is 0.5 acres per hour.
Answer:
see below
Step-by-step explanation:
The overbar on decimal digits means they repeat forever.
Any fraction with a denominator consisting of powers of 2 and/or 5 will terminate. These can be converted to decimal by multiplying the fraction by a number to make the denominator an appropriate power of ten.
1 2/3 = 1.66666666666... repeating
1 3/5 = 1 (3·2)/(5·2) = 1 6/10 = 1.6
1 1/4 = 1 (1·25)/(4·25) = 1 25/100 = 1.25
1 33/50 = 1 (33·2)/(50·2) = 1 66/100 = 1.66
Of course, your calculator can tell you the decimal equivalents, too.
