Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
Answer:
i think it 5rad3
Step-by-step explanation:
Y ∝x
y= kx
substitute x and y values
108= k x 9
because you want to find k on its own you divide both sides by 9
108 ÷ 9 = 12
So k = 9
Now that we have 12 we can use this to find y
y = 12 x 8
You just simply times it because that's what y is
so y= 96 when x=8
To find y when x= 7 you do 7 x 12 which is 84
So y= 84 when x= 7
