If your average speed is 2.05 and your time is the average of .87+.94+.72=0.843 then your answer should be 1.728 because distance= speed x time. I don’t know if this is correct because you didn’t label what the numbers were but I hope this helped you!! :)

A ramp leads up to a building. The top of the ramp is 5 feet above the ground, and the bottom is 15 feet from the building as sh
kirill [66]
To answer this you have to use Pythagoras's theorem: a^2 + b^2 = c^2

Put in the values:
5^2 + 15^2 = c^2

Simplify it:
25 + 225 = c^2

Simplify again:
250 = c^2

Square root both sides:
15.8113883008 = c

So the ramp is:
15.8113883008 feet

Now round the number: 
15.8ft

The above is the answer :)

The population of a bacteria sample doubles every 6 hours. How long would it take for the population to triple?
seraphim [82]

The way to solve this question is to essentially reverse the equation I used in the other answer.


I would solve this with some theoretical values. If you start with 3, how long would it take for it to triple, or reach 9.


the equation would look like 9 = 3(2)^t/6, note how the instead of 1/2 it is now 2 in the parenthesis, as it doubles every 6 hours rather than halves every amount of hours.


When placed into an algebra calculator, the answer should be about 9.5 hours
