Answer:
B
Step-by-step explanation:
So, to figure this out, we must find the total miles Maria ran in a week.
We know that she ran 2.75 miles each day.
She did this for 7 days.
Her goal was 17.5 miles.
So first, multiply the amount of days by the amount of miles per day:
7*2.75
=
19.25
So now we know that she ran a total of 19.25 miles in a week.
Since she onlu needed to run 17.5 miles, we can instantly rule out:
A - Runs less 17.5 miles
C - Runs exactly 17.5 miles
This leaves:
B - She runs 1.75 miles more than 17.5 miles
D - She runs 2.75 miles more than 17.5 miles
To figure out which on is correct, subtract her total miles by her goal:
19.25-17.5
=
1.75
So we know it must be:
B - She runs 1.75 miles more than 17.5 miles
This is because we figured out she ran an extra 1.75 miles.
Hope this helps! :)
Answer: The largest dimensions that are possible would be 50 foot by 125 foot.
Step-by-step explanation:
Since we have given that
Amount a farmer has available = $1500
Let x be the side perpendicular to the river.
Let y be the side parallel to the river.
Number of section perpendicular to the river = 3
cost of material for the side parallel to the river = $6 per foot
Cost of material for the side perpendicular to the river = $5 per foot
So, total cost becomes
Area would be
Now, put A' = 0 to get the critical points.
So, it becomes,
so, at x= 50 it will give maximum dimensions.
So, the largest dimensions that are possible would be 50 foot by 125 foot.
