Answer:
5/2
Step-by-step explanation:
5/2 because 2/5 times 4 is 8/2 plus 1/2 is 9/2
Answer:
The answer is 581 square centimeters
Step-by-step explanation:
So, if he has 4 dozen eggs, ten dollars per dozen, he has spent $40 on 48 eggs. <em>This means the cost of one egg = 48/40. </em>This can simplify to <em>6/5 </em>which is equal to<em> $1.20. </em>This means the value of one egg is $1.20, including the broken ones! So if six were broken, we multiply 1.20 x 6 which equals <em>$7.20!</em>
Use this "formula" to help find percentages
<em>Part/Total = %( Percentage )/ 100</em>
Now that we know how much money has gone to waste, we can plug in the known values into this "formula."
<em>7.2/48 = x/100</em>
Solve accordingly; cross multiply, 720 = 48x; divide both sides of the equation by 48 to isolate the variable, 720/48 = 48x/48; now you have your final answer which is:
15 = x; going back to the "formula" this means 15% of his money has gone to waste. I hope this helped! :)
<span>Since: v =sqrt(3)/2 s^2h
6779 liters x 0.0353cu ft/1 liter= 239.299 cu ft
but by proportion s/h = 10/25
s = 10/25 h
and v = sqrt(3)/2 (10/25 h)^2 h
239.299 = 0.139 h^3
h = (239.299/0.139)^(1/3) = 11.985 ft</span>
