Question

The ratio of trumpets to violins in a particular music classroom is 1 to 3 . If there are 9 trumpets in the classroom, how many violins are there?

2
3
9
27

The correct answer is: 27

No. of trumpets = 9
Ratio of trumpets to violins = $fraction numerator text no. of trumpets end text over denominator text no. of violins end text end fraction equals 1 third$ (given)
$text no. of trumpets end text equals fraction numerator text no. of violins end text over denominator 3 end fraction not stretchy rightwards double arrow text no. of violins end text equals 3 left parenthesis text no. of trumpets end text right parenthesis$
So, no. of violins = 3(9) =27.

I = $V over R$
The formula above is Ohm's law for an electric circuit with current I, in amperes, potential difference V, in volts, and resistance R, in Ohms. A circuit has a resistance of 500 ohms, and its potential difference will be generated by n six-volt batteries that produce a total potential difference of 6n volts. If the circuit is to have a current of no more than 0.25 ampere, what is the greatest number, n, of six-volt batteries that can be used?
