Answer:
Given: Population of ducks in lake, last year is 60.
Also, the population of ducks this year decreased by 1/4 th over the last year.
So, the population of ducks this year is = 60*(1-1/4)
= 60*(3/4)
= 45
Therefore, the population of ducks this year is 45 ducks.

Step-by-step explanation:
Divide 338 by 52 to get the answer
Answer:
Step-by-step explanation:
8d+2d+6d+9-6d = 0
First, combine like terms, so it would become;
10d+9 = 0
Then, separate anything without a variable;
10d = -9
Then you divide;
d= -0.9
The "mean" is the same thing as the "average".
To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.
If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.
If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.
Answer:
3
Step-by-step explanation:
Assuming you meant 
the degree is 3. The degree of a polynomial is always the highest degree one single term has. In this 
has a degree of 3, which is the highest in the polynomial, and therefore the answer. The degree of a term is the exponent or what the power of the term is. If the polynomial is in standard form, the degree will always be the first exponent.
