Answer: c=5.4
The two roots are 3/5 and 9/5
Step-by-step explanation:
assume 5x2−12x c=0 is supposed to be 5x^2 - 12x + c = 0
p = (12 + sqrt(144-20c))/10
q = (12 - sqrt(144-20c))/10
p-3q=0,
1.2 + 0.1sqrt(144-20c) +
-3.6 + 0.3sqrt(144-20c) = 0
-2.4 + 0.4sqrt(144-20c) +2.4 = 2.4
sqrt(144-20c) = 2.4/0.4 = 6
144-20c=36
144-36=20c
c = 108/20 = 5.4
5x^2-12x+5.4=0
x = 3/5 or x = 9/5
Answer:
The answer is 25.07 gallons/ 1 minute
Step-by-step explanation:
The question is asking for the unit rate of 752 gallons/30 minute as related to the minutes. So, you're looking for the ratio of gallons to 1 minute. To solve for this, you must divide the initial ratio of gallons to minutes by the initial minutes. so 752/30 and 30/30. Dividing 30 by 30 will give you 1. So, you know you'll be getting the unit rate. 752/30 is 25.0666666667. However, rounded to the nearest hundred will result in 25.07.
So your answer will be 25.07 gallons/ 1 minute (per minute).
