Answer:
72178.4777
Step-by-step explanation:
Easy! Just multiply 7 1/3 by 8 which leaves you with 58 2/3. Now, that 1/4 is 1/4 of an hour. If you can fill 7 1/3 boxes in 1 hour, how many can you fill in 1/4? 7 1/3 divided by 1/4 is 29 1/3. Add them together. 81 boxes.
The given expression is
81x²y³ + z
When x=3, y=4, z=19, then
81x²y³ + z
= 81*(3²)*(4³) + 19
= 81*9*64 + 19
= 46,675
Answer: D 46,675
