Answer:
1200 ml per hour
Step-by-step explanation:
To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:
![\frac{300~ml}{15~min}=\frac{x~ml}{60~mins}](https://tex.z-dn.net/?f=%20%5Cfrac%7B300~ml%7D%7B15~min%7D%3D%5Cfrac%7Bx~ml%7D%7B60~mins%7D)
Now we solve for x:
![\frac{300~ml}{15~min}\cdot 60~mins=x~ml](https://tex.z-dn.net/?f=%20%5Cfrac%7B300~ml%7D%7B15~min%7D%5Ccdot%2060~mins%3Dx~ml)
![\frac{18000~ml}{15} =x~ml](https://tex.z-dn.net/?f=%20%5Cfrac%7B18000~ml%7D%7B15%7D%20%3Dx~ml)
![1200~ml =x~ml](https://tex.z-dn.net/?f=%201200~ml%20%3Dx~ml)
And so, now that we know the value of x, the rate we wanted to find is
![\frac{1200~ml}{60~mins}](https://tex.z-dn.net/?f=%5Cfrac%7B1200~ml%7D%7B60~mins%7D)
Which is just 1200 ml per hour.
Answer:
Total price of the album including tax is $10.08
Step-by-step explanation:
Sales price without discount and tax = $12
% discount = 20%
Sales price with discount = 12 - (20/100 × 12) = 12 - 2.4 = $9.6
% sales tax = 5%
Tax = 5/100 × 9.6 = $0.48
Total price of the album including tax = $9.6 + $0.48 = $10.08
Answer: 108
Step-by-step explanation: The 40% percent taken away from $270 would be $108, because I round it to 50% percent off and that would $135 but since it's 40% off not 50% so I took away 10% from $135, and that's how I found my answer .
