make improper fractions first. Then look for a common denominator (7*9) you will get something like this:
((73*9 + 9*19*7)/(63))
24,717.
What you have to do is subtract 38,773-14,056 and then the answer would be 24,717. So all together 24,717 must be added to result in the sum of 38,773.
14,056+24,717=38,773.
She orders 5 pair in 5 different sizes:
5 x 5 = 25 pair
She orders 3 pair in 3 different sizes:
3 x 3 = 9 pair
Total pairs = 25 + 9 = 34 pair.
A triangular prism Vol. = area (A) of the triangular base × height (h) of prism
A triangular pyramid V = A × 1/3 h
So since they have same base A and h, the V of the pyramid will be exactly 1/3 the V of the prism
