Answer:
600 minutes or 10 hours
Step-by-step explanation:
We can solve this problem by looking at the net increase per minute. To find this, we can set rates for each value.
The pipe will be able to fill 1/120 of the tank in a minute, and the drain will drain 1/150 in a minute. So subtract the two:
1/120 - 1/150 = 1/600 of the tank per minute
Therefore you need 600 minutes to fill the tank, or 10 hours.
Answer:
well it uses the compound interest formula
F(x) = P_{0}(1 + \frac{r}{100})^x
so in your question
x = time in years for the initial formula
P_{0} = 293,.... r = 6% ...and...
then you need to substitute x = 4
simplify the brackets and you should get the answer.
10 is not a multiple of 3 so no 6/10 is not multiples for 3/10 and 6 is not a mutiple of 10 so it can't be also the same with 6/30 although 6/30 is multiples for 3 but 6 is not a mutiple for 10.
Answer:
x is less than -3
Step-by-step explanation:
3x^2+9x<0
x^2+3x<0
x(x+3)<0
x+3<0
x<-3
