Perimeter means the sides add up to 12.
Rectangles have two pairs of equal sides.
2(one side) + 2(another side) = 12
2 (one side + another side) = 12
(one side + another side) = 6
To draw a rectangle with a perimeter of 12 units, the two adjacent sides must add up to 6.
1 + 5
2 + 4
3 + 3

Hello!
To understand this question we first need to find some common measurements to make this math easier.
One day is equal to 24 hours.
One hour is equal 60 minutes.
One day in hours would be equal to 24 · 60, or 1440 minutes.
1440 is equal to 100% of our day.
To find 50% we can then divide that value in half to get 720 minutes.
Half of that value, or 25%, is equal to 360 minutes.
Answer:
Step-by-step explanation:
At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.
<u>Take two points:</u>
<u>Find the rate of change:</u>
This is a 2 gallons per 3 minutes
<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>
- 3 : (2/3) = 3* 3/2 = 4.5 minutes
