sin 15=0.65
Answer:
Colin gets 
of the total money
Step-by-step explanation:
If we let the total amount be "90" (or any multiple of 9), then the solution gets much easy.
Let total money be 90.
Caroline gets 1/9, so that is:
1/9 * 90 = 10
Remaining is 90 - 10 = 80
This 80 is divided in the ratio 1:3, that means Colin gets 1 part and Sarah gets 3 part. That is 1 + 3 = 4 parts altogether.
80 divided in 4 parts is 80/4 = 20 each part.
Colin gets 1 part, that is 1 * 20 = 20
Colin gets 20 OUT OF 90 (total initial).
<em>What proportion is that? We simply divide and reduce!!</em>
<em />
20/90 = 2/9
Colin gets of the total money
I think you might have forgotten to add Suresh typing speed table....
Time (min) Total words
0.5 28
3 168
14 784
We can easily obtain Suresh typing speed by dividing Total Words/Time
Time (min) Total words Speed (Words/min)
0.5 28 56
3 168 56
14 784 56
And we know that Nancie's typing speed is 35 Words/ min
So, Nancie's rate is less than Suresh's/
Its 2x^2-4x, to check it add it to 3x^2-2x or
2x^(2)-4x+3x^(2)-2x
To solve this problem, the formula can be used
I = P / T
Where I is the fraction of the sample
P is the amount of the sample
T is the total amount of sample
Since P = 252 chicken sandwiches and I = 0.55
And solve for T
T = 252 / 0.52
<span>T = 458 sandwiches in total</span>
