What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Robert slices a large loaf of bread to make 12 sandwiches. He made 3 turkey sandwiches and 5 veggie sandwiches. The portion of the ham sandwich will be calculated as below:-

Total sandwich = Turkish sandwich  +  veggie sandwiches + ham

12 = 5 + 3 + ham

ham = 12 - 8 = 4

Therefore, the fraction of the ham sandwich will be 4.

Answers

Volume (tank)=base x heitht
base is a squeare, so base=side²

Volume(Tank)=side² * height
600 m³=side² * 6 m
side²=600 m³/ 6 m
side²=100 m²
side=√(100 m²)=10 m.
