jack puts 1/3 pound of birdseed into his feeder every time he fills it. how many can jack fill his bird feeder with 4 pounds of
Flura [38]

Answer: Jack can fill his feeder 12 times with 4 pounds of birdseed.

Step-by-step explanation:

You need to analize the information given in the exercise, You know that every time Jack fills the feeder, he put \frac{1}{3} pounds into it.

Then, in order to solve this exercise, let "x" represents the number of times that Jack can fill his  feeder with 4 pounds of birdseed.

Keeping on mind the data provided in the exercise, you can set up de following proportion:

\frac{1}{\frac{1}{3}} = \frac{x}{4}

Finally, you must solve for "x" in order to find its value.

You get that this  is:

3= \frac{x}{4}\\\\(3)(4)=x\\\\x=12

Therefore, you can conclude that Jack can fill his feeder 12 times with 4 pounds of birdseed.

Row 0:                       1

Row 1:                      1     1

Row 2:                   1    2    1

Row 3:                 1    3    3     1

Row 4:               1   4   6     4     1

=========================================

Explanation:

This is known as Pascal's Triangle. Each value, other than the '1's, is found by adding the values directly above it. For instance, the '4' is the result of 1+3, and the 6 is a result of 3+3, and so on.

You can use the nCr combination formula to find the same values.

Alternatively you can expand out binomials of the form (x+y)^n, for integer values of n, and you'll find the coefficients of the terms match perfectly with Pascal's Triangle.
