Answer:
3600 gallons of water was removed from the basement.
Step-by-step explanation:
Given:
Rate of each pump = 40 gallons/min
We need to find find the number of gallons of water removed from the basement.
Solution:
Now Given:
After half an hour, the one pump burns out.
Now we know that;
1 hour = 60 mins
hour =
Now for 30 mins both the pumps were working and removing the water.
So we can say that;
Water remove for first 30 mins =
Also Given:
the second pump finishes removing the water half an hour later.
So we can say that;
Water removed for next 30 mins =
Now we can say that;
Total water removed from the basement is equal to sum of Water remove for first 30 mins and Water removed for next 30 mins .
framing in equation form we get;
Total water removed from the basement =
Hence 3600 gallons of water was removed from the basement.

Answer:
274 mL
Step-by-step explanation:
Often medical solutions expressed as a percentage are not really a percentage as such. A percentage is the ratio of two quantities with the same units.
Here, the context given by the problem suggests the "25%" solution is really (25 g)/(100 mL). That is, the units are grams and milliliters--different units.
With that assumption, we want to find the volume (v) of solution needed to deliver 6 g of medicine. An appropriate proportion* is ...
v/(6 g) = (100 mL)/(25 g)
v = (6 g)(100 mL)/(25 g) = 24 mL
So, the total volume of the infusion is ...
250 mL +24 mL = 274 mL
_____
* The concentration is given in terms of g/mL, but we have used a proportion that is mL/g. The reason for that is we want the variable to be in the numerator of the ratio. The variable here represents volume, so we have written the proportion with volumes in the numerators.
Having the variable in the numerator means the equation can be solved in one step--by multiplying by its denominator.
No, 3/4 is equivalent to 6/8 and 7/8 is in its final form
Answer:
Dylan
Step-by-step explanation:
Rate of Origami Making
1) June
= 10/30
= 1/3 origami birds per minute
2) Dylan
= 4/10
= 2/5 origami birds per minute
2/5 > 1/3
So Dylan was faster.
