Mika bought 9 rolls of film to take 180 pictures on a field trip. Some rolls had 36 exposures and the rest had 12 exposures. How

Juli2301 [7.4K]

The number of each type Mika bought =x = 6.8 rolls; y= 2.2 rolls.

<h3>Calculation using ratio</h3>

The number of rolls of film Mika bought = 9 rolls

The number of rolls that had 36 exposures = x

The number of rolls that had 12 exposures = y

The total number of exposures = 36 + 12 = 48

To find the exposure by one roll = 48/9 = 5.3

If one roll = 5.3 exposure

x roll = 36 exposure

Make x roll the subject of formula,

x roll = 36/5.3 = 6.8 rolls

If one roll = 5.3 exposure

y roll = 12 exposure

Make y roll the subject of formula,

y = 12/5.3 = 2.2 rolls

Therefore, the number of each type Mika bought = x = 6.8 rolls; y= 2.2 rolls.

Rounded would be about 37, or 36.8.

Hope this helps!!!!

$P=4a$

$d\sqrt{2a}$

Solving for P:

$P=2\sqrt{2d} =2*\sqrt{2*13.01}$ ≈36.79784
