Which number is greatest? 2.89 times 10 Superscript negative 8 1.997 times 10 Superscript 2 8.9 times 10 Superscript negative 6

love history [14]

<h3> The greatest number is $1.997 \times 10^2$ </h3>

<em><u>Solution:</u></em>

<em><u>Given that the numbers are:</u></em>

$2.89 \times 10^{-8}\\\\1.997 \times 10^2\\\\8.9 \times 10^{-6}\\\\5 \times 10^{-6}$

We have to find the number that is greatest

Convert the numbers to decimal

$2.89 \times 10^{-8} = 2.89 \times \frac{1}{10^8} =0.0000000289$

$1.997 \times 10^2 = 199.7$

$8.9\times 10^{-6}=8.9\times \frac{1}{10^6}=0.0000089$

$5\times 10^{-6}=5\times \frac{1}{10^6}=0.000005$

We can clearly see that, 199.7 is greatest number

Thus the greatest number is $1.997 \times 10^2$

Mr. Nelson drove for 6 2/3 hours at an average of 57 mph. How far did he drive?

xxMikexx [17]

$6\dfrac{2}{3}=\dfrac{6\cdot3+2}{3}=\dfrac{20}{3}\\\\v=\dfrac{s}{t}\\\\v=57mph;\ t=\dfrac{20}{3}h;\ s=?$

substitute

$\dfrac{s}{\frac{20}{3}}=57\ \ \ |\cdot\dfrac{20}{3}\\\\s=57\cdot\dfrac{20}{3}\\\\s=19\cdot20\\\\s=380\ miles$

Answer: 380miles.

Which expression is equivalent to 9^3/3^3

Allisa [31]

Answer:

3^3

Step-by-step explanation:

Exponents

9^3 can be rewritten as

3^2 ^3

Using exponent rules a^b^c = a^ (b*c)

3^2^3 = 3^6

3^6 / 3^3

We know that a^b / a^c = a^(b-c)

3^6 / 3^3 = 3^(6-3) = 3^3
