Answer:6.1
Step-by-step explanation: the equation is 6n=30.5+n. the first thing you you do is subtract n on both sides which would be 6n-n which gives you 5. the equation now is 5n=30.5. now what you do is divide 5 on both sides so it would be 30.5/5 and that gives you 6.1
Answer:
It will take 6.118 minutes to fill up the pool to a depth of 20 cm
Step-by-step explanation:
The first step is to calculate the volume of the wading pool.
we will assume it is a cylinder, hence the volume will be = ![\pi r^{2}h](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7Dh)
<em>Where r= radius of the pool = 115/2 = 57.5cm</em>
<em>h = depth of the pool =20 cm</em>
The volume of the pool will be ![\pi \times57.5^{2} \times 20 =2.08 \times 10^{5} cm ^{3}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes57.5%5E%7B2%7D%20%5Ctimes%2020%20%3D2.08%20%5Ctimes%2010%5E%7B5%7D%20cm%20%5E%7B3%7D)
We are filling a pool of 208,000cm ^{3} at the rate of 34000cm^3, cubed per minute.
To get the time it will take to fill up the pool, we will have to divide as follows:
208,000cm ^{3} / 34000cm^3 =6.118 minutes
Therefore it will take 6.118 minutes to fill up the pool to a depth of 20 cm
True, if you see the picture of a triangle with altitudes, the lines are drawn on the inside. Hope that helps!)
Answer: the answer is C or 736 cm2 (correct me if am wrong and am sorry if a i am)
I need help on that one too♀️
