Answer:

B. 1.2×10^-3 mm

Step-by-step explanation:

What constitutes an "appropriate" unit depends on the use of the number. Since we're not told of any particular use, we might choose the smallest of the available units: mm.

1.2×10^-3 mm

_____

<em>Additional comment</em>

The most appropriate unit would be the one that eliminates the power-of-ten multiplier:

= 1.2 µm

With both taps open, Blake can fill his kitchen sink in 6 minutes. When full, the sink drains in 10 minutes. How long will it ta

exis [7]

The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.

Step-by-step explanation:

Given that,

The kitchen sink can fill in: 6 mins

The sink can drain in: 10 mins

We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,

Lets say, the full tank = 1

Filling rate = $\frac{x}{6}$

Drainage rate = $\frac{x}{10}$

Hence, the time to fill the tank would be:

$\frac{x}{6} - \frac{x}{10} = 1$

$30.\frac{x}{6} - 30.\frac{x}{10} = 30.1$ (Multiply by LCM)

$5x - 3x = 30$

$2x = 30$

x = 15

Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.

natulia [17]

The rest of the statement is (3x+1) = 3x²+22x+7.

The divisor is one factor, and the quotient is the second factor. The factors get multiplied to make the dividend.
