mridul jogs around a rectangular park of 100m by 80m at the rate of 9km per hour. how much time will he take in jogging 6 rounds
anyanavicka [17]

Answer:

14minutes

Step-by-step explanation:

first you need to find the distance which you must find the perimeter P=100+80+100+80

=360 so you multiple it by 6 to get

=2160meters

so you need to convert the meters to kilometers

which is 1000m =1km

what about 2160m you cross multiply

to get 2.16km.

<em>so</em><em> </em><em>th</em><em>e</em><em> </em><em>di</em><em>stance</em><em> </em><em>repre</em><em>sent</em><em> </em><em>D</em><em>=</em><em>2</em><em>.</em><em>1</em><em>6</em><em> </em><em>km</em>

<em> </em><em> </em><em> </em><em>an</em><em>d</em><em> </em><em>spee</em><em>d</em><em> </em><em>represent</em><em> </em><em>S</em><em>=</em><em>9</em><em>k</em><em>m</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>now</em><em> </em><em>yo</em><em>u</em><em> </em><em>nee</em><em>d</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>time</em><em> </em><em>represented</em><em> </em><em>by</em><em> </em><em>T</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>T=D/S

T=2.16km/9km/h

so the km cancels each other

<u>you</u><u> </u><u>get</u><u> </u><u>0</u><u>.</u><u>2</u><u>4</u><u>h</u><u> </u><u> </u><u>for</u><u> </u><u>thi</u><u>s</u><u> </u><u>is</u><u>n't</u><u> </u><u>the</u><u> </u><u>solu</u><u>tion</u><u> </u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><em><u>you</u></em><em> </em><em>k</em><em>now</em><em> </em><em>th</em><em>at</em><em> </em><em>1</em><em> </em><em> </em><em>hour</em><em>=</em><em> </em><em>6</em><em>0</em><em> </em><em>minut</em><em>es</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>what</em><em> </em><em>about</em><em> </em><em>0</em><em>.</em><em>2</em><em>4</em><em>h</em><em> </em><em>you</em><em> </em><em>cr</em><em>oss</em><em> multiply</em>

<em>to</em><em> get</em><em> </em><em>1</em><em>4</em><em>.</em><em>4</em><em> </em><em>so</em><em> </em><em>you</em><em> </em><em>round</em><em> </em><em>it</em><em> </em><em>of</em><em>f</em><em> </em><em>t</em><em>o</em><em> get</em><em> </em><em>1</em><em>4</em><em> </em><em>minut</em><em>es</em>

In an arithmetic​ sequence, the nth term an is given by the formula an=a1+(n−1)d​, where a1 is the first term and d is the commo
Dmitry_Shevchenko [17]

Answer:

a_{10} = \frac{10}{65536}

Step-by-step explanation:

The first step to solving this problem is verifying if this sequence is an arithmetic sequence or a geometric sequence.

This sequence is arithmetic if:

a_{3} - a_{2} = a_{2} - a_{1}

We have that:

a_{3} = 40, a_{2} = 10, a_{3} = \frac{5}{2}

a_{3} - a_{2} = a_{2} - a_{1}

\frac{5}{2} - 10 = 10 - 40

\frac{-15}{2} \neq -30

This is not an arithmetic sequence.

This sequence is geometric if:

\frac{a_{3}}{a_{2}} = \frac{a_{2}}{a_{1}}

\frac{\frac{5}[2}}{10} = \frac{10}{40}

\frac{5}{20} = \frac{1}{4}

\frac{1}{4} = \frac{1}{4}

This is a geometric sequence, in which:

The first term is 40, so a_{1} = 40

The common ratio is \frac{1}{4}, so r = \frac{1}{4}.

We have that:

a_{n} = a_{1}*r^{n-1}

The 10th term is a_{10}. So:

a_{10} = a_{1}*r^{9}

a_{10} = 40*(\frac{1}{4})^{9}

a_{10} = \frac{40}{262144}

Simplifying by 4, we have:

a_{10} = \frac{10}{65536}
