\frac{(5-a)^{2}}{(5-b)(s-c)}+\frac{(s-b)^{2}}{(s-c)(s-a)}+\frac{(s-c)^{2}}{(s-a)(s-b)} |
|
Answer» When we take LCM We get (s-a)³ + (s-b)³ + (s-c)³ /(s-a)(s-b)(s-c) Since 3s = a + b+c Then Denominator will become 3 (s-a)(s-b)(s-c). Hence answer will be 3 |

7.Are the following pairs of lines parallel? Justify your answer:a.b.tc.95° B120°75°P.65°C 115°75° |
|
Answer» a. no they are not parallel.115+95=180vertically opposite angle of 95=95.115 and 95 are co interior angles.if their sum=180.then the two lines are parallel.115+95=210 so they are not parallel. b.they are not parallel.65 and 120 are co interior angles.their sum is 185.So they are not parallel. c.they are parallel.vertically opposite angle of 75 is 75.the 75+x=180.x=105.therefore 75,105 are co interior angles.75+105=180.so they are parallel. |

radius of circular base of an ear of corn is 6.6cm and its length is 11.2cm. If on average 1cmsq area contains 2 corns kernels, then what is the total number of kernels on a corn |
|
Answer» Curved surface area of corn = πrlNow, l = √( r² + h² )= √( 6.6² + 11.2² )= √( 43.56 + 125.44 )= √169 = 13 cmSo, curved surface area = 22/7 × 6.6 × 13 cm²= 269.7 cm²Now, when 1 cm² covers = 2 kernels Then 269.7 cm² will cover = 269.7 × 2 = 539.4 kernels Hence, 539 kernels ( approx. ) will be in the corn. |
