so assuming the tank is just a big tall rectangular box-like tank.
well, the volume of a rectangular prism is simply the product of its length, height and width. So the volume for this one will be 40 * 36 * 18, or 25920 ft³.
if we fill that up to only 5/6, not the whole tank, how much is 5/6 of 25920? well, is really just their product, namely 21600 ft³.
and then we dump 1/3 of that 21600, how much is that anyway? well 1/3 of 21600 is really just their product, so 7200 ft³.
so we had 21600 ft³ of water, and dumped 7200 ft³, we're left only with 21600 - 7200, or 14400 ft³.
Answer:
Mya’s equation
Step-by-step explanation:
Given that:
Detergent left in bottle after a certain number of washes x
Dexter’s equation,
y= -1.6x+50
Mya’s equation,
y = 50(.75)x
y = Detergent left in bottle.
Given that amount of Detergent left is about 1/2 ounces = y
For Dexter’s equation,
y= -1.6x+50
0.5 = 1.6x + 50
0.5 - 50 = 1.6x
-45.5 = 1.6x
x = 28.4375
For Mya’s equation :
y = 50(0.75)x
0.5 = 37.5x
0.5 / 37.5 = x
0.0133333 = x
Hence, Mya’s equation
