Answer:

176

Step-by-step explanation:

10 cents for 1 message because 9.10\91=.10 which is 10 cents

9.10=91 if you move the dot over once to the right you get your answer so...

17.60 mover to the right would be 176, .1 per text

A large container holds 8 gallons of water. After 56 minutes the container only has 1 gallon of water left. At what rate is the

Korvikt [17]

Answer:

The rate at which water leaking is $\frac{1}{8}$ gal/min.

Step-by-step explanation:

Given:

A large container holds 8 gallons of water.

After 56 minutes the container only has 1 gallon of water left.

Now, to find at what rate is the water leaking.

So, water leaked from the container = 8 gallons - 1 gallon = 7 gallons.

Time taken for leakage = 56 minutes.

Now, to get the rate:

$\frac{Gallons\ of\ water\ leaked}{Time\ taken\ for\ leakage}$

$=\frac{7 gallons}{56 minutes}$

$=\frac{1 gallon}{8 minutes}$

The rate = $\frac{1}{8}$ gal/min.

Therefore, the rate at which water is leaking is $\frac{1}{8}$ gal/min.

3^x= 3*2^x solve this equation

kompoz [17]

In the equation

$3^x = 3\cdot 2^x$

divide both sides by $2^x$ to get

$\dfrac{3^x}{2^x} = 3 \cdot \dfrac{2^x}{2^x} \\\\ \implies \left(\dfrac32\right)^x = 3$

Take the base-3/2 logarithm of both sides:

$\log_{3/2}\left(\dfrac32\right)^x = \log_{3/2}(3) \\\\ \implies x \log_{3/2}\left(\dfrac 32\right) = \log_{3/2}(3) \\\\ \implies \boxed{x = \log_{3/2}(3)}$

Alternatively, you can divide both sides by $3^x$ :

$\dfrac{3^x}{3^x} = \dfrac{3\cdot 2^x}{3^x} \\\\ \implies 1 = 3 \cdot\left(\dfrac23\right)^x \\\\ \implies \left(\dfrac23\right)^x = \dfrac13$

Then take the base-2/3 logarith of both sides to get

$\log_{2/3}\left(2/3\right)^x = \log_{2/3}\left(\dfrac13\right) \\\\ \implies x \log_{2/3}\left(\dfrac23\right) = \log_{2/3}\left(\dfrac13\right) \\\\ \implies x = \log_{2/3}\left(\dfrac13\right) \\\\ \implies x = \log_{2/3}\left(3^{-1}\right) \\\\ \implies \boxed{x = -\log_{2/3}(3)}$

(Both answers are equivalent)
