Let <em>x</em> = 0.424242... . Then 100<em>x</em> = 42.424242... . So we can write
100<em>x</em> - <em>x</em> = 99<em>x</em> = 42.424242... - 0.424242... = 42
which means
<em>x</em> = 42/99 = 14/33
and so
11.424242... = 11 + 14/33 = 377/33

Answer:
90/100
Step-by-step explanation:
You add 18 for every 20 students until you get to 100.
The lateral area of the prism is given by:
LA=[area of the two triangles]+[area of the lateral rectangles]
hypotenuse of the triangle will be given by Pythagorean:
c^2=a^2+b^2
c^2=6^2+4^2
c^2=52
c=sqrt52
c=7.211'
thus the lateral area will be:
L.A=2[1/2*4*6]+[6*8]+[8*7.211]
L.A=24+48+57.69
L.A=129.69 in^2
The total are will be given by:
T.A=L.A+base area
base area=length*width
=4*8
=32 in^2
thus;
T.A=32+129.69
T.A=161.69 in^2
