A=P(1+rt)
A/P=1+rt
A/P-1=rt
AP-P/Pr = t
A-1/r=t
Answer:
(4!+4)/4-4
Step-by-step explanation:
Answer:
369/10
Step-by-step explanation:
10 1/4=41/4
3 3/5=18/5
----------------
(41/4)(18/5)=738/20
simplify
369/10
The sum of those angles in a hexagon have to add up to equal 720. You have the means to find the 3 angles that are unmarked and undefined, leaving you only with z. z = 114. If you can't figure out how to find those other angles besides z, we can talk, but for all intents and purposes, you got your z of 114.
let's recall that d = rt, or namely distance = rate * time.
b = speed of the boat
c = speed of the current
now, we know that going downstream the boat went 16 miles total, that's going only one way, so the distance the boat travels downstream as well as upstream to return is 16 miles flat.
when going downstream, the boat is not really going at "b" speed, is really going at "b + c" speed, because the current is adding its speed to it, so is really going faster than "b".
when going upstream, the boat is not really going at "b" speed" either, is really going slower at "b - c" speed, because the current is against it and thus subtracting speed from "b".
let's take a look at those in a table
