Lincoln Middle School plans to collect more than 2000 cans of food in a food drive. So far, 668 cans have been collected. Write

Schach [20]

Let x be the unknown number.

<span>7x + 668 </span><<span> 2000</span>    => 7x plus 668 is less than 2000

where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.

7x + 668    < 2000
      - 668    -668
7x < 1332
÷7 ÷7
x < 190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000

What is the solution of the equation 3^x=12? Round your answer to the nearest ten-thousandth.

Lady_Fox [76]

Hey!

Okay, so if   $f(x)$ equals   $g(x)$ , then $In(f(x))$ equals   $In(g(x))$ . So, we'll plug in the numbers into this 'equation' we have now.

$In(3^{x} ) = In(12 )$

And now we'll apply this log rule →   $log_{a} (x^{b} ) = b * log_{a} (x)$

$In(3^{x} )=xIn(3) \\ xIn(3)=In(12)$

Now we have to solve $In(3^{x} )=xIn(3) \\ xIn(3)=In(12)$ . To do that, we'll divide both sides of the equation by   $In(3)$ .

$\frac{xIn(3)}{In3} = \frac{In(12)}{In(3)}$

Now we simplify

$x = \frac{In(12)}{In(3)}$

<em>So, this means the equation   $3^{x} =12$ solved is   $x = \frac{In(12)}{In(3)}$ or</em>  2.2619.

Hope this helps!

Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the enti

andrew-mc [135]

$40\ \frac{miles}{hour} \cdot \frac{1hour}{60minutes} = \frac{40}{60} = \frac{2}{3} \ \frac{ mile}{minute} \\ \\ Now \ that \ we \ have \ the \ speed \ in \ \frac{ miles}{minute} , \ when \ we \ calculate \ the \ time, \\ \\ it \ will \ also \ be \ in \ minutes \\ \\
time = \frac{distance}{speed} \\ \\
time=\frac{60}{\frac{2}{3}}= 60 :\frac{2}{3}= \not60 ^{30} \cdot \frac{3}{\not2^1}= 90 \ minutes \\ \\ Answer : \ Rene \ gets \ to \ the \ lake \ for \ 90 \ minutes$
