Answer:
$24.15
Step-by-step explanation:
Since we know its 35% of the original price we simply do 69×35% which equals 24.15. You can do it on your own work, or on a calculator to check.
You could also divide 69 by a hundred, which gives you .69 and multiply it by 35 which gives you the same answer
ρ - density, m - mass, V - volume
Liquid A:
Liquid B:
Liquid C:
The density of liquid C is approximately 0.96 g/cm³.
I think it goes something like this:
(X+1<5)^(X-4>-3)
-1 -1 +4 +4
___________________
X<4 ^ X>1
but i am not sure hope this way helpful..
Answer:
The pump fill the pool in 3/5 hours
Step-by-step explanation:
From noon to 1/4 hours later, the pool goes from 1/3 to 3/4 full. That's means that the pool fill X quantity in 1/4 hours, where X is calculate as:
So, the constant rate R can be calculated as:
That means that every hour the pool can be fill 5/3 full, so if we want to know how many hours is needed to fill the poll one time, we can write the following equation:
Where t is the time required to fill the pool. Solving for t we get:
t = 3/5 hours
so, the pump fill the pool in 3/5 hours or 36 minutes with a constant rate of 5/3.
3c^3. This is probably it. I'm pretty positive.
