Answer:
189
Step-by-step explanation:
3 4/5 + (3 4/5 - 1/2) =
19/5 + (19/5 - 1/2) =
19/5 + (38/10 - 5/10) =
19/5 + 33/10 =
38/10 + 33/10 =
71/10 which equals 7 1/10 tons <==
Approximate <em>R'</em> by using a linear approximation: for <em>x</em> close enough to 24, you have
<em>R'(x)</em> ≈ <em>L(x)</em> = <em>R' </em>(20) + <em>R''</em> (20) (<em>x</em> - 20)
Then
<em>R'</em> (24) ≈ <em>R'</em> (20) + <em>R''</em> (20) (24 - 20) = -4 + 50 (24 - 20) = 196
Ok, 65% of the attendants were men, 25% were women.
That leaves us with 10% remaining.
From those 10% .................The problem tells us that 40% are boys
So 10% * ( 0.4 ) = 4% ..............This means that 4% of the total attendants were boys.
So the distribution is
65%........men
25%........women
4%..........boys
6%...........girls
640 boys attended the game.....> this means that 4% of the total amount of people is 640.
So the number of persons that attended were
T= 100% *(640)) / 4% = 16000 people
