The ratio of boys to girls in a classroom is 15 to 12 . What is the ratio of boys to total students in the classroom?
zheka24 [161]

Answer:

15 to 27 (which is equal to 5:9)

Step-by-step explanation:

The ratio 15 to 12 indicates that there is a total of 27 people in the classroom (15+12).  So, if you want boys to total students, it's 15 to 27.  

You can divide each of these by 3 to simplify it and get 5:9.

Alecsey [184]

Answer:

<h2>1986, 1996</h2>

Step-by-step explanation:

       Given, Annual passenger revenue for the years 1980 to 2000 id=s modeled with the formula R=-40|x-11|+990.

Here, R is the annual revenue in millions of dollars, x is the number of years since January 1, 1980.

       Revenue in a year was $ 790 million.

So, R=790\\-40|x-11|+990=790\\40|x-11|=200\\|x-11|=5\\x-11=5\text{ (or) }x-11=-5\\x=16\text{ (or) }x=6

       So, after 6 yrs and 16 yrs from January 1, 1980, the Passenger revenue equals $ 790 million.

∴ Passenger revenue equals $ 790 million in 1986 and 1996.
