Given the amount of water needed to fill the cement dam and the water pump rate, the time needed to fill the dam is 400 minutes or 6hours 40minutes.
Option B)6h 40min is the correct answer.
<h3>How long does it take to fill the dam?</h3>
Given that;
- Amount of water needed to fill the dam A = 30000 litres
- Pump rate r = 75 litres per minute
- Time needed to fill the dam T = ?
To determine how long it take to fill the dam, we say;
Time need = Amount of water needed ÷ Pump rate
T = A ÷ r
T = 30000 litres ÷ 75 litres/minute
T = 400 minutes
Note that; 60min = 1hrs
Hence,
T = 6hours 40minutes
Given the amount of water needed to fill the cement dam and the water pump rate, the time needed to fill the dam is 400 minutes or 6hours 40minutes.

Using x as the number of adult tickets sold
If 3x as many student tickets were sold as adults
--> the number of student tickets is 3x
If the total tickets is 572 and made up of 3x and x
This equation represents the relation ship
Total = 572
number of adult tickets + number of student tickets = 572
x + 3x = 572
When solving for x, we will find the number of adult tickets
x+3x =572
4x=572
x= 572/4
x= 143
143 adult tickets were sold

Step-by-step explanation:
Answer:
The units digit of our number should be and can be any of 0, 2, 4, 6 (four opportunities).
The tens digit of our number should be and can be any of 0, 2, 4, 6 (four opportunities).
The hundreds digit of our number should be and can be any of 0, 2, 4, 6, 8 (five opportunities).
The thousands digit of our number should be and can be any of 2, 4, 6 (three opportunities).
So, there are 4*4*5*3 = 16*15 = 240 such 4-digits totally even numbers, satisfying the condition. ANSWER
