A winery has a vat with two pipes leading to it. The inlet pipe can fill the vat in 5 hours, while the outlet pipe can empty it

Rashid [163]

Answer:

$time=40/3hours\approx 13.3hours$

Step-by-step explanation:

The rates are additive: you can calculate the<em> inlet </em>rate and the <em>outlet</em> rate and add them algebraically, i.e. the inlet rate will be positive and the outlet rate will be negative.

<u>1. Inlet rate:</u>

$1vat/5hours$

<u />

<u>2. Outlet rate:</u>

$1vat/8hours$

<u>3. Net rate:</u>

$\text{Inlet rate - outlet rate}=1vat/5hours-1vat/8hours\\\\ \text{Net rate}=(8-5)vat/40hour=3vat/40hour=(3/40)vat/hour$

<u>4. Time to fill the vat</u>

$rate=amount/time\implies time=amount/rate\\ \\ time=1vat/(3vat/40hour)$

$time=40/3hours\approx 13.3hours$

Using the rules for special cases, what is the result of?

Arlecino [84]

Answer:

C) 4x^2 -8x +4[/tex]

Step-by-step explanation:

(-2x+2)^2

we apply (a+b)^2 formula

$(a+b)^2 = a^2 + 2ab +b^2$

a= -2x and b= 2

Replace 'a' with -2x and 'b' with 2

$(-2x+2)^2 = (-2x)^2 + 2(-2x)(2) +2^2$

(-2x)^2 is 4x^2

$(-2x+2)^2 = 4x^2 -8x +4$

option C is the answer

Which value of p makes the equation 18+ 2 (3p – 8) = –37 true?

Volgvan

Answer:

p = -6.5

Step-by-step explanation:

<u>Given:</u>

18+ 2 (3p – 8) = –37

<u>Solving for p:</u>

18+ 2 (3p – 8) = –37
18 + 6p - 16 = -37
6p + 2 = -37
6p = -37 - 2
6p = -39
p = -39/6
p = -6.5
