During 7 1/2 months of hibernation, a black bear experienced a weight loss of 64.4 pounds. on average, what was the bear's weight change per month? round to the nearest tenth. enter your answer in the box.

Bear's weight change per month = 8.6 pounds per month

Step-by-step explanation:

The weight change per month can be calculated by dividing the change in weight by the time it took for the weight change.

Here it is given that weight loss is 64.4 pounds.

And it took months for this weight loss to happen.

Therefore,

Bear's weight change per month =

=

=

=

=

Bear's weight change per month = 8.6 pounds per month

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
