Answer:
In the beginning, there is 60 L of water in the bathtub. The water drains out from the bathtub at 2.5 L per minute. How many minutes does it take until all of the water is drained out?
Zero of the function: (24, 0)
The value 24 min represents the number of minutes it takes for the water to completely drain out from the bathtub.
Step-by-step explanation:
Zero of the function is when y=0
0 = 60 -2.5 x
x = 24
Answer:
x = amount of pure acid to be added = 6.67ml
Step-by-step explanation:
George wishes to increase the percent of acid in 50ml of a 15% acid solution in water to 25% acid, how much pure acid must you add?
let
x = amount of pure acid to be added
15% of 50 + x = 25% of 50 + x
(0.15 * 50) + x = 0.25(50 + x)
7.5 + x = 12.5 + 0.25x
Collect like terms
x - 0.25x = 12.5 - 7.5
0.75x = 5
x = 5/0.75
x = 6.6666666666666
Approximately,
x = 6.67
x = amount of pure acid to be added = 6.67ml
It should cost $1.65 for each large drink.
You subtract $12 to $16.95 and that would give you 4.95 and divide it to the number of drinks they bought which is 3 and that would give you $1.65
