How much water conditioner for 2.5 gallon tank?

vivado [14]

If i'm correct you should add 0.5 mL to your 1 gallon tank, and I would say about 1.25 mL to your 2.5 gallon. It will not be extreme if you end up putting a little more in than you are supposed to. I'm not 100% because i haven't slept so my brain is being slow.

What is the missing length??

amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

$(15 + x) : (12 + 8) = x : 8$

$15 + x : 20= x : 8$

Convert to fraction

$\frac{15 + x}{20} = \frac{x}{8}$

Cross Multiply:

$(15 + x)*8 = 20 * x$

$120 + 8x = 20x$

Collect Like Terms

$20x - 8x = 120$

$12x = 120$

Solve for x

$x = \frac{120}{10}$

$x = 10$

<em>The length of the missing side is 10</em>

Given the formula A = 5h (B + b); solve for B.<br> 2

stellarik [79]

Answer:

B = A/5h - b; You could use

B = (A - 5hb)/5h This just puts everything over a common denominator.

Step-by-step explanation:

A = 5h (B + b) Divide both sides by 5h

A/5h = B + b Subtract b from both sides.

A/5h - b = B
