A pump empties the pool at the rate of 1000 gals every 4 hours how long does it take to pump our 20,000 gallons
Answer:
Step-by-step explanation:
Solving (9): The equation of the table
We start by calculating the slope (m)
Where:
The equation is then calculated using:
So, we have:
Open bracket
Solving (10):
Required
Find x
Divide both sides by 4.8
It is not a function did I do good
Hello!
A sample of Bromine-82 begins at 80 mL. We are given that this value will decrease by half of its current amount every 35 hours. First, we'll determine the number of times that 35 goes into 140. This will reveal the number of times we should divide the sample by 2:
140 ÷ 35 = 4
We have now proven that there are 4 periods of 35 hours in 140 hours. This means that we will divide the sample in half a total of 4 times, as follows:
1. 80 ÷ 2 = 40
2. 40 ÷ 2 = 20
3. 20 ÷ 2 = 10
4. 10 ÷ 2 = 5
We have now proven that an 80 mL sample of Bromine-82 will be reduced to only 5 mL after 140 hours. Therefore, the correct answer is 5 mL.
I hope this helps!
No, it's not reasonable.<br /><br />I'd much rather help you than blankly state the answer, so here I go.<br /><br />Ya' know those syringe's you see in science class. maybe you've had a lab with them, perhaps you've seen in them in shows. Now imagine that filled up with a superrrrrr tiny amount of water. Now imagine that in a bowl. See, it doesn't make sence.
*If it helps, one ml=one gram.
