I need help solving this! I need and answer fast

ZanzabumX [31]

So to solve this question the first step should be to make 7 equal to 42. To do this multiply 7 by 6, likewise with x-4.
The new equation should be 42/6x-24 = 42/12.
We now can just get rid of the numerators (top number) to get 6x-24=12.
The next step is to add 24 to both sides which would leave you with 6x=36.
Divide by 6 and the answer should be x=6

Work out the area of this semicircle.Take pie to be 3.142 and give your answer to 2 decimal places 10cm

rosijanka [135]

Answer:

The area of the semi circle $A = 157.1 cm^2$

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given radius of circle 'r' = 10 cm</em>

<em>The area of the circle formula </em>

<em> </em> $A = \pi (r)^{2}$ <em></em>

<em>The area of the semi circle formula </em>

$A = \frac{\pi (r)^{2} }{2}$

taking π =3.142

$A = 3.142 X \frac{(10)^2}{2}$

On calculation , we get

$A = 157.1 cm^2$

<u><em>Final answer</em></u>:-

<em>The area of the semi circle </em> $A = 157.1 cm^2$ <em></em>

1) find the mean,
   20+10+30+20+50+30+40+20/8= 27.5
2) Find the distance of each value from that mean
   20- 7.5
   10- 17.5
   30- 2.5
   20-7.5
   50- 22.5
   30- 2.5
   40- 12.5
   20- 7.5
3) Find the mean of those distances
   7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10

The Mean absolute deviation for this data set is 10.
