ANTONII [103]

Answer:

The voltage in exponential form would be $(\frac{3}{5})^3$ .

The original voltage in the circuit is $\frac{3}{5}$ of a volt.

Step-by-step explanation:

Let x represent the original voltage.

We have been given that the voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has been reduced 3 times.

The original voltage multiplied by itself for 3 times would be $x\cdot x\cdot x=x^3$ .

Now, we will equate $x^3$ with 27/125 as:

$x^3=\frac{27}{125}$

We know that 27 is cube of 3 and 125 is cube of 5, so we can represent our equation as:

$x^3=\frac{3^3}{5^3}$

$x^3=(\frac{3}{5})^3$

Therefore, the voltage in exponential form would be $(\frac{3}{5})^3$

Now, we will take cube root of both sides to find original voltage in the circuit as:

$\sqrt[3]{x^3} =\sqrt[3]{(\frac{3}{5})^3}$

Using property $\sqrt[n]{a^n} =a$ , we will get:

$x =\frac{3}{5}$

Therefore, the original voltage in the circuit is $\frac{3}{5}$ of a volt.

Maria made 7 2/3 pints of juice. She drank 5/6 pint of the juice and poured 3/4 of the remaining juice equally into 3 bottles. H

Ivahew [28]

First, change 7 2/3 to an improper fraction

7 x 3 = 21 + 2 = 23

23/3 is the amount Maria made

Find a common denominator for all: 24

(23/3)(8/8) = 184/24

(5/6)(4/4) = 20/24

Subtract the amount she drank from the whole

184/24 - 20/24 = 164/24

Find 3/4 of the bottle

(164/24)(3/4) = 5.125

finally, divide the number gotten with 3

5.125/3 = 1.70

1.70 pints were in each bottle.

hope this helps
