Dan does an experiment to find the value of A. He measures the circumference and the diameter of a circle.
He measures the circumference, C, as 170 mm to the nearest millimetre.
He measures the diameter, d, as 54 mm to the nearest millimetre.
Dan uses t =
( to find the value of a.
Calculate the upper bound and the lower bound for Dan's value of .
(4 marks)
upper bound =
lower bound =

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
