Answer:

450L

Step-by-step explanation:

This is a ratio and proportion problem. First you need to determine the known ratio and the unknown ratio. In this case we have the known ratio:

$\dfrac{20 lbs}{3L}$

The unknown ratio in this case is:

$\dfrac{3,000lbs}{xL}$

So to do this, we just set up the proportion and solve for it:

$\dfrac{20lbs}{3L}=\dfrac{3,000lbs}{xL}\\\\{20lbs}=\dfrac{3L\times3,000lbs}{xL}\\\\{xL}=\dfrac{3L\times3,000lbs}{20lbs}\\\\{xL}=\dfrac{9,000L}{20}\\\\xL = 450L$

Answer:

Step-by-step explanation:

a= b^c << === >> logb(a) = c

a b c

Convert 45 = 9^√x << === >> log9 (45) = √x

1.7324867604 = √x

3.0 = x squared both sides

I used a log calculator on the internet when a Gaggled log calculators

$1)\\\\\dfrac{-45}{-5}=45:5=9$

$2)\\(-2)(4)=-8\\(2)(-4)+-8\\-16:2=-8\\-16:(-2)=8\neq-8\\\\\text{All of the following expressions have the same value except}\ -16:-2.$

$3)\\-3^2=-3\cdot3=-9$

$(-2)^4=(-2)(-2)(-2)(-2)=16\\-2^4=-(2)(2)(2)(2)=-16\neq16\\(-2)(-2)(-2)(-2)=16\\2^4=(2)(2)(2)(2)=16\\\\\text{All of the following are equivalent except}\ -2^4.$
