Hi there :)
So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.
Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.
Good luck with the rest of your assignment, have a good day/night!!
The water will last for 3 days
<em><u>Solution:</u></em>
Given that, village having a population of 4000, requires 150 litres of water per head per day
<em><u>Let us first find the volume of tank</u></em>
The tank measuring 20m x 15m x 6m
Length = 20 m
Breadth = 15 m
Height = 6 m
![volume\ of\ tank = length \times breadth \times height](https://tex.z-dn.net/?f=volume%5C%20of%5C%20tank%20%3D%20length%20%5Ctimes%20breadth%20%5Ctimes%20height)
![Volume\ of\ tank = 20 \times 15 \times 6 = 1800](https://tex.z-dn.net/?f=Volume%5C%20of%5C%20tank%20%3D%2020%20%5Ctimes%2015%20%5Ctimes%206%20%3D%201800)
Thus volume of tank is 1800 cubic meter
From given,
Water required per person per day = 150 liters
<em><u>Therefore, water required for 4000 people per day is:</u></em>
![\rightarrow 4000 \times 150 = 600000 \text{ liters }](https://tex.z-dn.net/?f=%5Crightarrow%204000%20%5Ctimes%20150%20%3D%20600000%20%5Ctext%7B%20liters%20%7D)
Convert to meters
![600000 \text{ liters } = 600000 \times \frac{1}{1000}\ m^3\\\\600000 \text{ liters } = 600\ m^3](https://tex.z-dn.net/?f=600000%20%5Ctext%7B%20liters%20%7D%20%3D%20600000%20%5Ctimes%20%5Cfrac%7B1%7D%7B1000%7D%5C%20m%5E3%5C%5C%5C%5C600000%20%5Ctext%7B%20liters%20%7D%20%3D%20600%5C%20m%5E3)
<em><u>How many days will the water of this tank last?</u></em>
![\text{Number of days water will last } = \frac{\text{volume of tank}}{\text{total water required per day}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20days%20water%20will%20last%20%7D%20%3D%20%5Cfrac%7B%5Ctext%7Bvolume%20of%20tank%7D%7D%7B%5Ctext%7Btotal%20water%20required%20per%20day%7D%7D)
![\text{Number of days water will last } = \frac{1800}{600} = 3](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20days%20water%20will%20last%20%7D%20%3D%20%5Cfrac%7B1800%7D%7B600%7D%20%3D%203)
Thus the water will last for 3 days
40+1=41
10×4+1=41
that is what I have so there you go
Answer:
8 square inches
Step-by-step explanation:
The area is the number of square inches a shape covers. To find the area of a triangle use the formula A = 1/2 b*h. Here b = 4 and h = 4.
So the area is A = 1/2 4*4 = 8 square inches
