Answer #1

We have 3 lots of Bronze weighing 3.45 grams, 48.5 grams, and 147.863 grams

If they are melt and are combined, the answer will just be the sum of all three numbers with appropriate significant number. In addition, we look only at the significant figures after decimal and keep the least significance digits. Here, 3.45 has 2 digits after decimal, 48.5 g has only 1 whereas 147.683 g has 3 digits. Thus, we will keep the least digits i.e. 1 digit after decimal.

Total weight = 3.45 g + 48.5 g + 147.863 g= 199.813 g = 199.8 g

So, the answer will be 199.8 g

Write a Racket function "combine" that takes two functions, f and g, as parameters and evaluates to a new function. Both f and g will be functions that take one parameter and evaluate to some result. The returned function should be the composition of the two functions with f applied first and g applied to f's result.
