Answer:
C) x=7root 2 and y=7
Step-by-step explanation:
by using tan 45
which is equal to opp/adjacent side
so we get 1=7/y
therefore y=7
using pythogorus theorum we get that
x=root of 7^2 +7^2
which is seven root 2
change to improper fractions
8 1/2 = (2*8+1)/2 = 17/2
2 1/4 = (4*2+1)/4 = 9/4
17/2 divided by 9/4
copy dot flip
17/2 *4/9
17/9 *4/2
34/9
change back to a mixed number
3 remainder 7
3 7/9

Answer:
5 minutes.
Step-by-step explanation:
We have been given that the number of minutes needed to drain a bathtub, m, varies inversely as the rate of draining, r.
We know that two inversely proportional quantities are in form , where y is inversely proportional with x and k is constant of proportionality.
Upon substituting our given variables in inversely proportion, we will get:
Let us find constant of proportionality using our given information.
So our required equation would be .
Now, we will substitute in our equation to solve for time.
Therefore, it will take 5 minutes to drain the bathtub at a rate of 32 liters per minute.
