Answer: OPTION C.

Step-by-step explanation:

According to the Quotient of powers Property, if you divide two numbers whose base is the same, you must rewrite the base and subtract the exponents. Observe:

\frac{a^m}{a^n}=a^{(m-n)}

Notice that "a" is the base and "m" and "n" are the exponents.

Therefore, knowing this property, you can solve the exercise.

Given the following expression:

\frac{3^{15}}{3^3}

You can notice that the base 3 is in the numerator and in the denominator, then you must  apply the Quotient of powers Property and subtract the exponents.

You get that the result is:

=3^{(15-3)}=3^{12}

Suppose it takes 18 hours for a pipe to fill a tank of water, if the tank
Lemur [1.5K]

Answer:

Step-by-step explanation:

Let the volume of tank be x

In 18 hours volume of tank filled = x

we have to find the volume of tank which is filled in 1 hours.

For that we divide LHS and RHS by 18

In 18/18 hours volume of tank filled = x/18

In 1 hours volume of tank filled = x/18

In 30 hours volume of tank emptied = x

we have to find the volume of tank which is emptied in 1 hours.

For that we divide LHS and RHS by 30

in 30/30 hours volume of tank filled = x/30

In 1 hours volume of tank filled = x/30

If tank is empty and one starts to fill it, two things will happen

it will start filling at rate of x/18 hours

But there is leak which will start to empty the tank at  x/30 hours

So , at any given time rate if filling of water will be rate of filling the tank- rate of emptying the tank

In 1 hour volume of tank filled if both filling and leaking takes place simultaneously =  x/18 -x/30 = (30-18)x/18*30 = 12x/18*30 = x/3*15 = x/45

In 1 hour volume of tank filled = x/45

in 1*45 hour volume of tank filled = x/45*45 = x

Thus, it will take 45 hours to fill the leaky tank  .

(Use distributive property)<br> 6 (5x + 3)
S_A_V [24]

Answer:

30x + 18

Step-by-step explanation:

Using distributive property, you can find the answer like so.

Multiply 6 and 5x first

6(5x + 3)

30x + 3

Now multiply 6 by 3

6(5x + 3)

30x + 18

Hope I explained this well to you. :)

13c = 1,690<br><br><br><br> What is the value of c?
Ivan

Answer:

130

Step-by-step explanation:

If you replace the value of c with 130, you can multiply 13 with 130 to get your answer.

13 x 130 = 1690

Or, you can multiply 13 with 13 and add the 0 onto the end. This makes the same answer. To add a zero onto the end of a number multiply it by ten.

169 x 10 = 1690
