I guess the chef is making the mixture for the sheriff... Let <em>x</em> be the amount of dressing with 5% vinegar that is required, and <em>y</em> the amount of 15% vinegar dressing (both amounts in mL).
The sheriff wants 390 mL of the mixed dressing, so that
<em>x</em> + <em>y</em> = 390
<em>x</em> mL of the 5% dressing contains 0.05<em>x</em> mL of vinegar, while <em>y</em> mL of the 15% dressing contains 0.15<em>y</em> mL of vinegar. The resulting mixture should have a concentration of 9% vinegar, so that it contains 0.09 (390 mL) = 35.1 mL of vinegar. This means
0.05<em>x</em> + 0.15<em>y</em> = 35.1
Solve for <em>x</em> and <em>y</em> :
<em>y</em> = 390 - <em>x</em>
0.05<em>x</em> + 0.15 (390 - <em>x</em>) = 35.1
0.05<em>x</em> + 58.5 - 0.15<em>x</em> = 35.1
23.4 = 0.10<em>x</em>
<em>x</em> = 234
<em>y</em> = 156
Answer:
<em>37cm = 370 millimeters</em>
<em>37cm = 0.37 meter</em>
<em>37cm = 0.00037 kilometers</em>
Step-by-step explanation:
37cm = 370 millimeters
37cm = 0.37 meter
37cm = 0.00037 kilometers
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
