If the population of an ant hill doubles every 10 days and there are currently 100 ants living in the ant hill, what will the ant hill population be in 20 days?
Answers
Answer:
400
Step-by-step explanation:
The current number is 100, it doubles every ten days, and you're asking what the size will be in twenty days.
Beginning:
100 ants (ten days pass)
100 x 2 = 200
Middle:
10 of the 20 days have passed
Your new number is 200 ants
End:
200 ants (ten days pass)
Since every ten days the size doubles: 200 x 2 = 400
400 ants after 20 days

Use the benchmark fraction one half , 1, and 0 to help you estimate each answer before you solve. a one twelve mile b one and five twelfths miles c one and seven twelfths miles d twelve seventeenths mile
Answers
Answer: megan went a total distance of 1 5/12 miles or 17/12 (use which ever you need)
Step-by-step explanation:
Here, we want to calculate the total distance worked around the track
We are told that she ran 9/12 and skipped 8/12
The total distance around the track will be the sum of these two
Mathematically, that will be;
9/12 + 8/12= 17/12 but if wanted in mixed fraction [tex]1\frac{5}{12}[/tex]

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?
PLSS HELPP
Answers
Answer:
On first visit, weight =550 g
Weight gained on second visit= 350 g
Weight gained on third visit= 300 g
Present weight=550+350+300= 1200
Weight gained=1200-550=650
Percentage of weight increased
-------->650/550 × 100 = 118.18\%
So the kitten gained 118% weigh

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.
Answers
Answer:
3.391 Gallons Per Minute
Step-by-step explanation:
78/23=3.391
Round 3.391 to 3.4
Answer:
≈3.39130434783 gallons per minute
Step-by-step explanation:
The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:
[tex]78 : 23[/tex] OR [tex]\frac{78}{23}[/tex]
We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:
[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]
And of course, if there's a need to round, go ahead.
And please do not waste water!
