760 total students....4 out of 7 graduated...3 out of 7 didn't
so 4/7(760) = 3040/7 = 434.28 <== so approx. 434 will graduate
and 3/7(760) = 2280/7 = 325.7...and approx. 326 won't graduate
Answer:
See below
Step-by-step explanation:
REMEMBER sec = 1/cos ...so the left side is
[1/cos -1] / [1/cos +1 ]
get common denominator for numerator and denominator
[ (1 -cos) /cos ] / [ (1+cos) / cos ]
now flip the bottom fraction and multiply to get
[(1-cos/cos) ] * [ cos / (1+cos) ] which simplifies to ( the 'cos' term cancels)
(1-cos) / (1+cos) done !
Well you need to find the y-intercept (the number after the number with the x) and plot that number on the graph. next you need to find the slope (ex. 3x+4 the slope would be 3/1) and then you would plot the rest of the points using the slope. and last you would draw a line through the points.
£840 - 100%
100%-5%=95%
840*95%:100% = 798 (£) - <span>the number sought</span>
