Ahummingbird's heart beats about 1250 beats per minutes while flying. that's h beats per minute faster than at rest. write an expression for how many times it heart beats per minute while at rest

you can use a^2+ b^2=c^2

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
