Would it just be 45 songs?
I believe the correct answer from the choices listed above is the first option. The equation that can be used to solve the problem would be x + (x + 9) = 47.
The sum of two numbers is 47. ---> x + y = 47 where x is the smaller number and y is the larger.
The greater number is 9 more than the smaller number. -----> y = x + 9
x + ( x + 9 ) = 47
Volume without holes = 3 x 6 x 11 = 198 cubic inches.
Calculate volume of one hole:
3.14 x 0.5^2 x 3 = 2.355 cubic inches
There are 3 holes: 3 x 2.355 = 7.065
Subtract volume of the holes from the brick:
198 - 7.065 = 190.935 cubic inches.
Rounded to the nearest tenth: 190.9 cubic inches.
