U have to add If u want to know the sum
Use the rule of 3, note that we will convert the hours to minutes:
60 - 84
75 - x
(75 * 84) / 60 = x
6,300 / 60 = x
105 = x
105 minutes = 1h 45m
Hope it helped,
Happy homework/ study/ exam!
Answer:
(a) y = ±(√x)/2
Step-by-step explanation:
You want to find y such that ...
x = f(y)
x = 4y^2 . . . . . . . put in the expression for f(y)
x/4 = y^2 . . . . . . .divide by 4
±√(x/4) = y . . . . . take the square root
y = ±(√y)/2 . . . . . simplify
