Cerrena [4.2K]

Answer:

176 of 12% vinegar

44 of 7% vinegar

Step-by-step explanation:

Percentage vinegar required = 11%

Volume = 220 mL

First brand % = 7%

Second brand % = 12%

Let p = volume of 12% vinegar material

Mixture :

0.12p + 0.07(220 - p) = 220 * 0.11

0.12p + 15.4 - 0.07p = 24.2

0.05p = 8.8

p = 8.8 / 0.05

p = 176

176 of 12% vinegar and

220 - 176 = 44

44 of 7% vinegar

\sf\huge\underline\red{SOLUTION:}

Use formula:

\sf{V = \pi(\frac{d}{2})^2h}

Solving for diameter:

\sf d = 2 \times  \sqrt{ \frac{V}{\pi h} }  \\ \sf = 2 \times   \sqrt{ \frac{40}{\pi \times 1800} } \approx0.16821 \\  = \sf \large\boxed{\sf{\green{d = 0.17}}}

\sf\huge\underline\red{FINAL \: ANSWER}

\large\boxed{\sf{\green{d=0.17}}}

What two numbers multiplies to 36 and add to negative 21
anastassius [24]
Factor 36 and add them, make sure both are negatie
1+36=37, nope
2+18=20 nope
3+12=15,nope
4+9=13, nope
6+6=12, nope

the closest one is 20

I hope you meant adds to -20, because if you did, then answer is -2 and -18

if you did mean 36 and adds to -21, then the numbers are \frac{-21-3 \sqrt{33} }{2} and \frac{-21+3 \sqrt{33} }{2}, aprox -19.1168 and  -1.8831
