Answer:
(27/4, -1/4)
Step-by-step explanation:
Answer: by combining 1/4 and 1/3 and then you find the amount of left over dog food. Multiply the fractions so they have common denominators, then add. You will get 3/12 + 4/12 = 7/12. 12 - 7 = 5, so there is 5/12 of the bag left.
Step-by-step explanation:
Use similar volume to calculate
which is the (ratio of edges)^3 = (ration of volume)
so just put the numbers in, let the volume of smaller pyramid be y.
(3/4)^3 = y/320
27/64 = y/320
y=135in3
Answer:

Step-by-step explanation:
We can use the FOIL method to expand two multiplied binomials. It states that
. The FOIL method stands for First(first terms) outer(outer terms) inner(inner terms) last(last terms).
So, we can expand our binomials now!
