The answer is D. 1,000,000
A calculator would answer this, but i’m assuming your asked to make a estimate without a calculator. An easier way to look at dividing by fractions would be multiplying by its reciprocal
Since this fraction is .004 or 4/1000 the reciprocal would be 1000/4, or 250.
Since 250 times 4,367 is still a relatively hard multiplication problem. I would just make the 250, 200.
Now that the problem is simplified, a trick when multiplying any number divisible by 10, is to take the zeros out, multiply the number, then add them back.
So 4,367 x 2 = about 8,600, then adding two 0s from the 200, that is now 860,000.
Looking at the answers the closest to this is 1,000 so the answer is D
3/8 of a foot = 3/8 x 12/1 or 4 1/2 inches
So our 1/2 inch grows by a factor of 9 because 4 1/2 ÷ 1/2 = 9 Think how many 1/2 dollars are in 4 1/2 dollars. (Answer is 9)
So our 8 4/9 in the catalog has to grow the same
8 4/9 x 9 = 8 4/9 x 9/1 = 76/9 x 9/1 or 76 inches which is 6 ft 4 inches.
(76 ÷12 = 6 r4)
Answer:
456 squirrels
Step-by-step explanation:
We have the following formula:
N = M * C / R
Where "N" is the estimated population size, "M" is the number of individuals already tagged, "C" is the total number of those caught the second time regardless of whether or not they are tagged, and "R" is the total number of tagged recaptured individuals.
Now, replacing we have:
N = 114 * 96/24
N = 456
Therefore, there are approximately 456 squirrels in the conservation area.
Answer:
8 classes
Step-by-step explanation:
Given
Required
The number of class
To calculate the number of class, the following must be true
Where k is the number of classes
So, we have:
Take logarithm of both sides
Apply law of logarithm
Divide both sides by log(2)
Round up to get the least number of classes
Joel spent 72.5% of his time exercising after playing soccer on Tuesda
<h3>How to determine the percentage?</h3>
The given parameters are
Minutes spent on Tuesday = 27 more minutes than Monday
Total minutes spend = 60
This means that
Tuesday = Monday + 27
Monday + Tuesday = 60
Make Monday the subject in Tuesday = Monday + 27
Monday = Tuesday - 27
Substitute Monday = Tuesday - 27 in Monday + Tuesday = 60
Tuesday - 27 + Tuesday = 60
Evaluate
2 * Tuesday = 87
Divide by 2
Tuesday = 43.5
The percentage of time spent exercising on Tuesday is then calculated as
Percentage = 43.5/60 * 100%
Evaluate the expression
Percentage = 72.5%
Hence, Joel spent 72.5% of his time exercising after playing soccer on Tuesday
