Step-by-step explanation:

$a^n=\underbrace{a\cdot a\cdot a\cdot...\cdot a}_{n}$

$8=2\cdot2\cdot2=2^3\\\\16=2\cdot2\cdot2\cdot2=2^4\\\\32=2\cdot2\cdot2\cdot2\cdot2=2^5\\\\64=2\cdot2\cdot2\cdot2\cdot2\cdot2=2^6\\\\128=2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2=2^7\\\\256=2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2=2^8$

In a village, there was an epidemic and the population decreased by 10%. If there were only 1800 people left in the village, wha

tester [92]

$\bold{\boxed{\huge{\blue{\underline{Answer }}}}}$

$\bold{\underline{ Given :- }}$

$\sf{The\: population\: is\: decreased \:by\: 10 percent }$

$\sf{There\: were \: only \: 1800 \: people \: left}$

$\bold{\underline{ To\: Find :- }}$

$\sf{we \: have \: to \: find\: original \: population? }$

$\bold{\underline{ Let's \: Begin :- }}$

$\sf{Let \: the \: total \: population\: be \: x }$

$\sf{\underline{ Therefore }}$

$\sf{According \: to \: the \: question }$

$\sf{ x - 10/100 = 1800 }$

$\sf{ 100x - 10/100 = 1800}$

$\sf{ 100x - 10 = 1800 × 100}$

$\sf{100x - 10 = 180000}$

$\sf{ 100x = 180000 + 10}$

$\sf{ x = 180010/100}$

$\sf{ x = 1800.1 }$

$\bold{\pink{Hence , The\: original \:population \:of \: the\: village \:is \:1800.1 }}$

in a cookie jar,1/5 of the cookies are chocolate chip and 1/2 of the rest are peanut butter.What fraction of all the cookies is

Tamiku [17]

If 1/5 are chocolate chip, then 4/5 are not chocolate chip because 1 - 1/5 = 4/5.

Half of 4/5 are peanut butter. Half of 4/5 is 2/5, so 2/5 of the cookies are peanut butter.

Write the slope-intercept form of the equation of each line 13x-2y=14

HACTEHA [7]

Answer:

Step-by-step explanation:

First, lets put this into y=mx+b form.

You can bring the 13x over to the 14, by subtracting and you get -2y=14-13x, or also -2y = -13x + 14

Then you can divide both sides by -2 to get y, and you get

-2y/-2 = -13x/-2 + 14/-2 which is simplified to y=13/2x + (-7) which is

y=13/2x-7

{[( IMPORTANT )]}

THIS HAS THE SLOPE IN A IMPROPER FRACTION... CHECK IF YOU USE MIXED NUMBERS OR IMPROPER FRACTIONS

the mixed number form is y = 7 1/2 x -7

Hope this helps!
