You divided cm³ by litres, that's where you went wrong.
The volume of the cilinder is 753982 cm³ which is 753.982 litres
To fill it takes 753.982/0.2 seconds ≈ 3769.9 seconds.
In an hour there are 60*60=3600 seconds, so it takes slightly more than one hour.
But as you can see you were very close. It helps to always write the unit with any number.
Answer:m<b=m<d+125 degrees

Answer:
B. (0, 4)
Step-by-step explanation:
so we need to find the value of m and n, and luckily we have 2 equations that'll help. (I'm going to use the substitution method for this instead of the Elimination method because I am lazy)
first we need to solve for m, but we already have an equation that tells us what m is equal to, m = n - 4.
now we just need to plug in our new m into the other equation and solve for n. (we are using m + 5n = 20 for that)
so now we get
(n - 4) + 5n = 20
so we solve for n
n + 5n = 24
6n = 24
n = 4
now that we know that n is 4, we can plug that into our m equation (m = n - 4)
m = 4 - 4
m = 0
now we have our m and n, and we can make our ordered pair.
(m, n)
(0, 4)
You can easily do this yourself. It takes more effort to create the question. Just multiply 22.854 by 5 then divide by 4 = 28.5675.
