Answer:

D.

Step-by-step explanation:

First, multiply straight across and put everything together:

\frac{3a}{b}\cdot \frac{b^2}{12c}=\frac{3ab^2}{12cb}

Notice we can simplify by cancelling a b and reducing 3/12:

=\frac{ab}{4c}

This cannot be simplified further.

D.

How do i draw two number lines that show 0.20 and 1/5 are equivalent?
leonid [27]
The frist line may be one with the numbers 0, 1 and 2 and 10 divisions (marks at equal distance) between each integer. Each division will be equal to 0.1 units and then you can mark the second division from the zero point to the right as the 0.20 mark.

The other line must have the same integers, 0 , 1 and 2 placed in identical form as the first line. Then
   - draw an inclined straight line since the point zero,
   - mark 5 points in the inclined lined equally spaced over the line.
   - draw a sttraight line from the 5th point to the point with the mar 1 over the base number line.
   -  draw a parallel line to the previous one passing trhough the second point of the inclined line and mark the point where this parallel touchs the base number line. This point shall be at the same distance from zero than the 0.2 mark was in the first number line, meaning that 0.2 and 1/5 are equivalent.

Solve -9(t - 2) = 4(1-15).
snow_lady [41]

Answer:

t = 74 / 9

Step-by-step explanation:

-9(t - 2) = 4(1 - 15)

-9t + 18 = 4 - 60

-9t + 18 = -56

 -18      -18

-9t = -74

/-9     /-9

t = 74 / 9

ira [324]

Answer:

Step-by-step explanation:

Given that for X the amount of credit card debt for U.S. adults under 35, is

having mean as 8724 dollars.  

For this point estimate to be unbiased and most accurate we must ensure that

i) The sample represents the population

ii) Samples are drawn at random

iii) Sample sizes are sufficienly large.

Hence we see that C is not right as college students cannot represent the entire population.  Tv poll cannot be said to be random since there may be a significant population who was not aware about this poll.  A and B are right but B is better with more sample size.

Divide completely for the question below
juin [17]

Answer:

B) 5x^2

Step-by-step explanation:

\sqrt{\frac{50x^5}{2x} }

We can divide 50 by 2, we get 25 and we can cancel out x from x^5.

Therefore, we get

\sqrt{\frac{25x^4}{1} }

= √25x^4

When we take the square root of 25, we get 5 and √x^4 = x^2.

Taking the square root, we get

= 5x^2

Answer: B) 5x^2

Thank you.
