Umm I honestly don’t know
Answer:
reeee
Step-by-step explanation:
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
<u>Step-by-step explanation:</u>
Total mass of acid required= 85 ounces
Let the mass of 72% acid be 'a'
Let the mass of 25% acid be 'b'
a + b = 85
b = 85-a
85(40/100) = a(72/100) + b(25/100)
85(2/5) = a(72/100) +(85- a) (25/100)
34 = (72a/100) + (2125/100) - (25a/100)
34 - (2125/100) = (72a + 25a) /100
(3400-2125)/100 = 97a /100
97a = 1275
a = 13.15 ounces
b = 85 - 13.14
b = 71.85 ounces
13.15 ounces of 72% acid and 71.85 ounces of 25% acid are needed
Answer:
125%
Step-by-step explanation:
If you take the question
66 is what percent of 52.8?
and convert it into an equation it would be
66=x*52.8
Using this information we divide 66 by 52.8 this then gives us our final answer of 1.25 or 125%
Convert 16 tenths into .16 so
5 - .16 = 4.84
