Tyler used 114 gallons of paint to paint 47 of a fence. How many gallons will it take to paint the whole fence?

lara31 [8.8K]

Answer: It will take 199.5 gallons to paint the whole fence.

Step-by-step explanation:

Given: Paint required to paint $\dfrac47$ of fence = 114 gallons

Then , paint required to paint whole fence = $114\div\dfrac47$

i.e. paint required to paint whole fence = $114\times\dfrac{7}{4}$

i.e. Paint required to paint whole fence= 199.5 gallons

Hence, it will take 199.5 gallons to paint the whole fence.

According to Boyle's Law, if the temperature of a confined gas is held fixed, then the product of the pressure P and the volume

Bad White [126]

If PV = 800, then P can be written as a function of V,

P(V) = 800 / V

(a) The average rate of change of P as V increases from 200 to 250 in³ is then

(P (250) - P (200)) / (250 in³ - 200 in³) = (3.2 lb/in² - 4lb/in²) / (50 in³)

... = -0.016 (lb/in²)/in³

(Or -0.016 lb/in⁵, but I figure writing the rate as (units of pressure) per (unit volume) makes more sense.)

(b) We can also write V as a function of P :

V(P) = 800 / P

Take the derivative:

V'(P) = - 800 / P²

which immediately demonstrates that V'(P) ∝ 1 / P², as required. (The fish-looking symbol, ∝, means "is proportional to".)

If differentiating is supposed to be more involved, you can use the limit definition:

$V'(P)=\displaystyle\lim_{h\to0}\frac{V(P+h)-V(P)}h$

$V'(P)=\displaystyle\lim_{h\to0}\frac{\frac{800}{P+h}-\frac{800}P}h$

$V'(P)=\displaystyle\lim_{h\to0}\frac{\frac{800P-800(P+h)}{P(P+h)}}h$

$V'(P)=\displaystyle800\lim_{h\to0}\frac{-\frac h{P(P+h)}}h$

$V'(P)=\displaystyle-800\lim_{h\to0}\frac1{P(P+h)}=-\dfrac{800}{P^2}$
