Answer» Answer: (4)the given numbers are 2/7 and 6/7 we KNOW that, 2 < 3 < 4 < 5 < 6 ∴ 2/7 < 3/7 < 4/7 < 5/7 < 6/7 hence, three rational numbers lie between 2/6 and 6/7 are 3/7 = 0.428571429 , 4/7 = 0.571428571 , 5/7 = 0.714285714 (5) A COMPLEMENTARY angle are two angles whose sum is 90°. If one angle is 63,then take the other angle 'x'.. 63+x = 90 x=90-63 x= 27° (6) (9p + 16q) + (13p + 2Q) ⇒ 9p + 16q + 13p + 2q ⇒ 9p + 13p + 16q + 2q ⇒ 22p + 18q (7) We NEED to find square root of 625 by repeated subtraction method. 625−1=624 624−3=621 621−5=616 616−7=609 609−9=600 600−11=589 589−13=576 576−15=561 561−17=544 544−19=525 525−21=504 504−23=481 481−25=456 456−27=429 429−29=400 400−31=369 369−33=336 336−35=301 301−37=264 264−39=225 225−41=184 184−43=141 141−45=96 96−47=49 49−49=0 At last the answer comes out to be 0. Here number of steps to find this is 25. Thus square root of 635 is 25. |
