Answer:
About 12 ft
Step-by-step explanation:
using a simple graph on a calculator, you can convert you sq feet to feet, hope this helps.
To fill 1/5 meters it takes:
3/5 divided by 4 1/2
=3/5 divided by 9/2
=3/5 x 2/9
=2/15
To fill 5/5 or 1 meter it takes:
2/15 x 5
=10/15
=2/3
Therefore, it takes 2/3 minutes to fill an empty aquarium to a depth of 5/5 or 1 meter.
Answer:
B
Step-by-step explanation:
Parallel lines have the same slope while perpendicular lines have slopes which are negative reciprocals.
Here the slope of line m is 5/3.
Here the slope of line n is -3/5.
These lines are perpendicular.
Line n crosses through point k and can be shown through substitution. Substitute (5,-4) into line n.
y = -3/5 x - 1
-4 = -3/5(5) - 1
-4 = -15/5 - 1
-4 = -3 - 1
-4 = -4
The solution is B where n passes through K and the lines are perpendicular.
0.33 because 1.98 divided by 6 is 0.33 which is the unit rate
