To estimate, you would usually round to a significant figure
so, 20* 70=1400
The actual answer is 1521, so we know we are close
If i understand the question correctly the plane will fly 6 trips of 500 miles each trip.
Number of minutes it takes the plane to fly 500 miles
= 500 / 11
= 45.45 minutes
For 6 trips this = 45.45 * 6 = 272.73 minutes
= 4.55 hours to nearest hundredth.
Answer:
2/3
Step-by-step explanation:
The slope of a line can be computed as:

where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(0,1) and (3,3)
Therefore, the slope of the line is

Two lines are said to be parallel if they have same slope: therefore, a line parallel to the one shown should also have slope of 2/3.
Step-by-step explanation:
there must be something wrong or missing in your problem description.
what I can read here :
-97 - 7 when divided by 2
-97 - 7 = -104
this divided by 2 is -52.
but there is no such answer.
so, the provided answers and the problem description do not fit to each other.
