Evaluate the following using<br> powers of ten rules.<br> 104)1.042
Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = \frac{1.042}{10^4}

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

\frac{1.042}{10^4}=0.0001042

Therefore, answer is 0.0001042

The speed, v, of a wave is inversely proportional to the square root of the
yKpoI14uk [10]

Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

v \sqrt{d} = k    

If v  = 30 and d = 400, then

30(\sqrt{400}) = k

k = 30(20) = 600

Now v \sqrt{d} = 600

If d = 25, then v\sqrt{25} = 600

                         5v = 600

                            v = 120
