Dividend’’. This is due toSolution
The demographic dividend is a rise in the rate of economic growth due to a rising share of working age people in a population. This usually occurs late in the demographic transition when the fertility rate falls and the youth dependency rate declines.
Evaluate:
√729 + √49 - √16 + 1/√64
Simplify:

(1/5)(40% of 800 – 120) = ? × 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 – 20% of 5280) = ? ÷ 3
∛157464 =?
