Answer:
B) Brand 2
Step-by-step explanation:
Brand 1: $10.68 ÷ 12 = 0.89
Brand 2: $9.44 ÷ 16 = 0.59
Brand 3: $15.30 ÷ 18 = 0.85
Brand 4: $21.84 ÷ 24 = 0.91
Brand 5: $20.40 ÷ 30 = 0.68
Least cost per packet is of Brand 2
Answer:
Brand 2 is cheapest per 1 single dip from the 12
We know its cheaper each packet as we divide by its number of dips to its total to find single dip prices.
Therefore, as example single dip for Brand 2 = $0.59
The others range from $0.59 to $0.91 making the single range $32 (the difference in values higher to lower) as a single dip cost.
Their mean is 392 / 5 = $0.78 as a single dip cost.
Step-by-step explanation:
Brand 1 12 10.68 = 0.89
Brand 2 16 9.44 =0.59
Brand 3 18 15.30 =0.85
Brand 4 24 21.84 = 0.91
Brand 5 30 20.40 = 0.68

Answer:
Step-by-step explanation:
cylinder's height=3×(diameter of sphere)=3×6=18 cm
radius of cylinder=3 cm
volume of cylinder=π r²h=π(3)²×18=162 π cm³
volume of sphere=4/3 π(3)³=36 π cm³
reqd. empty space=162 π-3×36π=54 πcm³
