Question

One-half the square of b

Answer 1

A machine produces 240 bolts in 25 minutes. At the same rate how many bolts would be produced in 45 minutes

Answer 2

`(b^2)/(2)`

Explanation:

We are supposed to write an algebraic expression for given word phrase.

The square of b would be 'b' raised to second power:
`b^2`.

Half the square of b would be
`b^2` divide by 2:
`(b^2)/(2)`.

Therefore, our required expression would be
`(b^2)/(2)`.
