Vera is using her phone. Its battery lifw is down to 2/5 and it drains another 1/9 fraction every hour. How long will her batter

just olya [345]

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:)

Elena has 35 magazine subscriptions to sell. Each magazine subscription costs $8.50. Elena sold 17 magazine subscriptions on Fri

KengaRu [80]

Answer : The answer is $153.00 from selling magazine subscriptions on Saturday.

Explanation : We know that each magazine is equal to $8.50. At first she sold 17 of the 35 magazines. 17 x $8.50 = $144.50 from selling 17 magazines. Now we do 35-17 to get how many magazines are left. So there is 18 magazines left. We need to do the same thing we did before, 18 x $8.50 = $153.00. She got $153.00 from selling 18 magazines on Saturday.

Write an equation to represent the total amount Shauna will owe her parents

Misha Larkins [42]

This would actually be a very broad question. So, when considering these kinds of questions, one thing that we would really want to consider would be the $(x)$ value in this case. We would want to find the amount, and also the terms of the expression.

So, let's suppose that the amount would be 200.

And let's say that Shauna makes 5 a week.

Then the expression would then look like $\boxed{5w=200}$

$(w)=weeks \\ \\ (5)= how \ much \ she \ makes \ in \ a \ week. \\ \\ so \ we \ do \ the \ amount \ she \ makes, \ and \ then \ \\multiplied \ by \ the \ amount \ of 
 \ weeks.$

I hope this would help you in your case of the problem! :)
