Says 123 minutes is longer than 120 that's why it is that answer
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

Answer: w, 0
Step-by-step explanation:
you can see that G has the same distance from 0 as E does, so you can just take away the - sign. It hasn't left the line so its still 0.
Answer:
7x^2 -5x + 4
Step-by-step explanation:
5x^2 – 6x+2
- (-2x^2 - x - 2)
We got 5x^2 - (-2x^2) = 5x^2 + 2x^2 = 7x^2
-6x - (-x) = -6x + x = -5x
2 - (-2) = 2+2 = 4
So the equation would be 7x^2 -5x + 4

24 out of 120
24 / 120 = 0.2
Move the decimal two places to the right: 20.

3 is 12% of (unknown number)
12% × x = 3
or 12 / 100 × x = 3
Multiplying both sides by 100 and dividing both sides by 12,
we have x = 3 × (100/12)
x = 25
