Answer:
30 minutes to 40 minutes.
Step-by-step explanation:
From the graph attached,
Distance of Sabrina from her home has been given on y-axis and time taken is on x-axis.
Sabrina's walked 2 miles to reach the library in the duration = 30 - 0
= 30 minutes
She stayed at the library from 30 minutes to 40 minutes (Represented by the straight horizontal line).
Then the third segment represents the journey of Sabrina from library to home.
Therefore, Sabrina was at the library between 30 minutes to 40 minutes.

Answer:
The equation for the nth term of the given arithmetic sequence is: 
Step-by-step explanation:
We need to write an equation for the nth term of the arithmetic sequence:
15,28,41 ....
The equation for arithmetic sequence is: 
Where 
is the nth term, 
is first term and d is common difference
In the given sequence we have:
a₁ = 15
a₂ = 28
We can find common difference using the formula:
So, the common difference d is 13
Now, equation for nth term will be:
So, the equation for the nth term of the given arithmetic sequence is:
where n=1,2,3..
Answer: She's wrong.
Step-by-step explanation:
Numbers of hours used in solving homework last week = 15
Numbers of hours used in solving homework this week = 18
Percentage increase = (18 - 15) / 15 × 100
= 3/15 × 100
= 1/5 × 100
= 20%
Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.
Besides the obvious one(81*1), the only 2 combinations are 9 and 9, or 27 and 3.
