\huge \: \bf \: Question:—

\sf \longmapsto6^9+6^8)/(6^8 \times 6^{-9})

\huge\bf Solution:—

\sf \longmapsto \:  \dfrac{ {6}^{9} +  {6}^{8}  }{ {6}^{8}  \times  {6}^{ - 9} }

\sf \longmapsto \dfrac{10077696 +  {6}^{8} } { {6}^{8}  \times {6}^{ - 9}  }

\sf \longmapsto \dfrac{10077696+1679616}{ {6}^{8} \times  {6}^{ - 9}  }

\sf \longmapsto \:  \dfrac{11757312}{{6}^{8} \times  {6}^{ - 9}}

\sf \longmapsto \dfrac{11757312}{1679616(6 {}^{ - 9} )}

\boxed{\bf \: As \: a^{-n} = 1/a(n) \: ,}

\sf \longmapsto \dfrac{11757312}{1679616  \bigg(\dfrac{1}{10077696} \bigg )}

\sf \longmapsto \dfrac{11757312}{ \dfrac{1}{6} }

\sf \longmapsto \:  \: 70543872

\boxed{\bf \:  \: \: Convert\: 70543872 \: to\: scientific \: notation}

\sf \longmapsto \: 7.0543872 × 10 {}^{7}

Step-by-step explanation:

<h3><u>Question</u><u>:</u><u>-</u></h3>
  • To simplify the expression

<h3><u>Expression</u><u>:</u><u>-</u></h3>
  • \frac{( {6}^{9}  +  {6}^{8} )}{( {6}^{8}  \times  {6}^{ - 9} )}
<h3><u>Solution</u><u> </u><u>:</u><u>-</u></h3>

= \frac{( {6}^{9}  +  {6}^{8} )}{( {6}^{8}  \times  {6}^{ - 9} )}

  • <em>[</em><em>In</em><em> </em><em>numerator</em><em> </em><em>we</em><em> </em><em>take</em><em> </em><em>6</em><em>^</em><em>8</em><em> </em><em>common</em><em>]</em>

= \frac{ {6}^{8} ( {6} +  1)}{( {6}^{8}  \times  {6}^{ - 9} )}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  \frac{( {6}^{8} \times 7)}{( {6}^{8}  \times  {6}^{ - 9} )}

  • <em>[</em><em>In</em><em> </em><em>denominator</em><em> </em><em>as</em><em> </em><em>we</em><em> </em><em>know</em><em>,</em><em> </em><em>a</em><em>^</em><em>x</em><em> </em><em>×</em><em> </em><em>a</em><em>^</em><em>y</em><em> </em><em>=</em><em> </em><em>a</em><em>^</em><em>(</em><em>x</em><em>+</em><em>y</em><em>)</em><em>]</em>

= \frac{( {6}^{8}   \times 7)}{( {6}^{8 + ( -9)} )}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

= \frac{( {6}^{8}   \times 7)}{( {6}^{ - 1} )}

A sample of men's heights was taken and the mean was 68.8 inches. The standard deviation is 2.8 inches. What percent of the men
jarptica [38.1K]

Answer:

87.29%

Step-by-step explanation:

Given: Mean= 68.8 inches

           Standard deviation= 2.8 inches

           

Now, finding the percent of the men in the sample were greater than 72 inches.

We know, z-score= \frac{x-mean}{standard\ deviation}

z-score= \frac{72-68.8}{2.8}

⇒ z-score= \frac{3.2}{2.8} = 1.14

∴ z-score= 1.14

Next, using normal distribution table to find percentage.

Coverting 0.8729 into percentage= 0.8729\times 100

We get the percentage as 87.29%

Hence, 87.29% of the men in the sample were greater than 72 inches.

Which equation can be used to solve for the rate, r, for Sam to change all the light bulbs in the office building by himself?
Bad White [126]

Answer:

\frac{3}{r}+\frac{3}{8}=1

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Working together, Sam and Charlie can change all light bulbs in the office building in 3 hours. It would have taken Charlie 8 hours to do the job alone. Which equation can be be used to solve for the rate 'r', for Sam to change all the light bulbs in the office building by himself.

Let Sam can change the bulbs in the office alone in 'r' hours  

Per hour work done by Sam alone = \frac{1}{r}

Let Sam takes he time to change the same bulbs in the office alone = 8 hours

Per hour work done by Sam = \frac{1}{8}

Since, Sam and Charlie complete the work together in time = 3 hours

Therefore, per hour work done by both = \frac{1}{3}

Equation for per work done by both will be,

Per hour work done by both = Per hour  work done by Sam alone + Per hour work done by Charlie

\frac{1}{r}+\frac{1}{8}=\frac{1}{3}

Therefore, equation for the rate 'r' will be,

\frac{1}{r}+\frac{1}{8}=\frac{1}{3}

\frac{3}{r}+\frac{3}{8}=1

You have two gifts to buy. You plan to spend no more than $40 on the two gifts combined. You want to spend at least twice as muc
belka [17]

You will spend a total of $39 on both gifts which is less than $40 and have spend twice as much on the first gift as you did the second ($13 x 2= $26).

IRINA_888 [86]

Answer:

  • a sphere
  • the definition needs to restrict all of the points to a plane

Step-by-step explanation:

In 3-dimensional Euclidean space, a sphere is the set of all points the same distance from a given point. The given definition of a circle only applies when the given point and the solution set are in the same plane, and the geometry is Euclidean.
