There will be excactly 400 fiction books. The ratio of fiction to all is 4 to 9, or 4 to 900.
Answer:
you get the measure of angle XYZ by adding the measures of angles XY? and ZY?
70 +35 = 105 degrees is the measure of angle XYZ
8x²+3y²=24
8x²+3y²-24=0
Let x be 1 ,
Therefore
8+3y²-24=0
3y²-16=0
3y²=16
y²=16/3
y=4/1.7
y=40/17
<em><u>Take</u></em><em><u> </u></em><em><u>different</u></em><em><u> </u></em><em><u>values</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>&</u></em><em><u>y</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>plot</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>graph</u></em><em><u>!</u></em><em><u>!</u></em><em><u>!</u></em>
SA= 2LW + 2LH + 2WH
Substituting for the values, SA = 900 cm^2
