I can’t see anything I would have helped you

a winery has a vat with two pipes leading to it. the inlet pipe can fill the vat 7 hours, while the outlet pipe can empty it in

raketka [301]

Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.

Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)

For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.

So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.

Now just divide the size of the vat by that number, and you find your answer.

70 gallons / 3 gallons per hour = 23 1/3 hours.

Express the polynomial as a product of linear factors f(x)=2x^3+4x^2-2x-4

Iteru [2.4K]

$f(x)=2x^3+4x^2-2x-4=2(x^3+2x^2-x-2)\\\\=2[x^2(x+2)-1(x+2)]=2(x+2)(x^2-1)=2(x+2)(x^2-1^2)\\\\\boxed{f(x)=2(x+2)(x-1)(x+1)}\\\\Used\ (a-b)(a+b)=a^2-b^2$

What is 6/100 + 2/10

Andreyy89

Answer:

$\frac{26}{100}$

Step-by-step explanation:

$\frac{6}{100}$ can stay untouched, but $\frac{2}{10}$ has to be changed to $\frac{20}{100}$ . Now that they have they have the same denominator, you can add them. $\frac{6}{100} + \frac{20}{100} = \frac{26}{100}$ , which can be simplified, which is $\frac{13}{50}$ .
