Question

Adrian loves the pancakes! The problem is, the recipe serves only six, and he has 540 people in his family (including aunts, uncles, and cousins). Now, he needs help increasing the recipe to feed his entire family. However, Adrian is particular - he insists on using only three significant figures with scientific notation.

Answer 1

Answer:

ingredient. U.s unit. SI unit. SI unit(540)

flour. 2cups. ²/6. 180cups = 1.8×10²

milk. 2cups. ²/6. 180cups. =1.8×10²

eggs. 2. ²/6. 180eggs. =1.8×10²

melted butter. ⅓cup ¹/18. 30cups. =3×10¹

sugar. 1spoon. ¹/6. 90spoons. =9×10¹

baking powder 2spoons ²/6. 180spoons. =1.8×10²

salt. ½spoon. ¹/12. 45spoons. =4.5×10¹

Explanation:

1) to get the SI unit divide the U.S unit by 6

example:eggs = 2÷6. =²/6

2) to get the SI unit for 540 people ,multiply the SI unit by 540.

example:eggs ²/6×540. = 180

3)convert the answers to scientific notation

example:eggs =180. =1.8×10²
