Dear SailorMars, #4's question is very convoluted so I won't show you how to do it. Luckily, I do know how to do #5 and #6. With #5, multiply 8 5/6 by two to get 17 2/3, then do 50-17 2/3 to get 32 1/3 ft of tape. With #6, add 11 1/2 and 6 4/5 to get 18.3 gallons of gas, then do 18.3-3 3/10 to get 15 gallons of gas used.
Answer:
8/25, 0.16, 16%
Step-by-step explanation:
P(#>4) = P(5)+P(6) = 4/25+4/25 = 8/25
Answer:
A) 1/13
B) 1/52 (or 1/4)
Step-by-step explanation:
52 cards in total.
4 Queens in total.
4/52=1/13
1 Queen of diamonds.
1/4 of 1/13 = 1/4×1/13 = 1/52
The second part of the question isn't overly clear, so I think that the answer is most likely 1/52, but could be 1/4.
Answer:
X=4
Step-by-step explanation:
We just have to see what equals 22 added with 6 <em>and 16+6=22</em> and<em> 16/4=4</em>
Find the difference between the two prices:
617.40 - 420 = 197.40
Now divide the difference by the wholesale price:
197.40 / 420 = 0.47 = 47% markup.
