-First question: 74cm squared
-Second question: 21.8628 ft squared (not sure what to round to)
H. Looks like you circled it, so yes, you’re right!
Let x be the total number of beavers. We mark 119 out of x beavers. Then, we found 39 marked beaver out of 89 caught beavers. So, if we build the proportion

we get, solving for x,

So, it is reasonable to suppose that there are about 272 beavers in total. Note that this is an estimate, both numerically and conceptually, since we have no information about the set of beavers caught at the beginning and the end of our experiment.
Answer:
The correct answer is option C.
Step-by-step explanation:
Precision is defined as the closeness of two or more measurements to each other.This is how much close are the series of measurements of a same object to each other.
For example : If we measure volume of water in flask which comes out to be 2 mL and again on measuring for the number of times we get same value of 2 mL. Hence, this measurement will said to be precise.
A scale measures weight to the nearest 0.5 lb.So, from the given options the measurement which is appropriate to the given precision scale is 140.5 lbs.
Answer:

Step-by-step explanation:

When dividing fractions, you just need to remember that all you need to do is get the inverse of the divisor and multipy.
So for the problem
5 = divident
3/4 = divisor
So we get the inverse of 3/4 which is 4/3 and then multiply.
Look above to see the process.
