sin 50' ka maan

Answer»

As previously mentioned, it depends upon the units of the argument.

Radians. 50 radians is several complete turns, in fact nearly 8. 50 = 15.915 π. So if we take sin(50 radians) we get: sin(50) = –0.262 374 853 704

Degrees. sin(50°) = 0.766 044 443 119

powlnci casts d sllddow Jmiongk travels 14 km in 25 minutes. I the speed remains the same, howfacan it travel in 5 hours?

Answer»

Let the distance travelled by the truck in 5 hours be x km.We know, 1 hour = 60 minutes∴ 5 hours = (5 × 60) minutes = 300 minutes

The given information in the form of a table is as follows.Distance travelled (in km)14xTime (in min)25300

The distance travelled by the truck and the time taken by the truck are directly proportional to each other. Therefore,

14/25 = x/300

x = (14 x 300)/25 = 168

Hence, the distance travelled by the truck is 168 km.

10 cm long cylindricalfrustum of a cone. If thdiameter of the cylindr12.CBSE 2012The radii of the circular ends of a bucket of height 15 cm are 14 cm andr em (r< 14). If the volume of bucket is 5390 cm3, find the value of r

Answer»

Volume of the bucket=1/3πh(R²+r²+Rr)

=5390=1/3*22/7*15(196+r²+14r)

=5390=22/7*5(196+r²+14r)

=5390*7/110=196+r²+14r

=49*7=196+r²+14r

=343=196+r²+14r

=0=196-343+r²+14r

=0=r²+14r-147

=r²+21r-7r-147=0

=r(r+21)-7(r+21)=0

=(r-7)(r+21)=0

r=7 or -21(rejected)

hence r=7

125+(20-13÷2(20)-13-14)×20

Answer»

125 + (20 - 13 ÷ 2(20) - 13 - 14)*20

= 125 + (20 - 13÷40 - 27)*20

= 125 + (20 - .325 - 27)*20

= 125 + (20 - 27.328)*20

= 125 + (-7.325)*20

3. Letbe a rational number and y be an irrational number. Is x+ ynecessarily an irrational number? Give an example in support of your2010,'14answer

Answer»

Rational Number are those numbers which can be expressed in the form p/q where q is not equal to 0 and p and q belongs to integers a rational number can be expressed in the form of decimal too.

Say x = 2and y = 3

It clearly states that x+y =5 ( Product is not following the definition of Rational numbers )Proving that x+y is an irrational number.

Rational means number between two integer say x and y are 2 and 3 respectively.

=1/2(2+3)=5/2 or 2.5 ( Rational number of x and y we get which follow the definition of Rational number )

Or (a) Briefly discuss the different pathways of energyproduction by oxidation of glucose in differentorganisms

Answer»

After conversion of glucose into pyruvate , energy can be released by any of the 3 pathways .1. Aerobic respiration - Pyruvate is oxidized in the presence of enough oxygen to release water, carbon dioxide and energy in the form of 38 ATPs. This process is conducted in mitochondria.2. Anaerobic respiration - energy is released in the presence of less amount of oxygen then required. The end products are 2ATPs and lactic acid.3 .Fermentation-This pathway is followed by yeast to respire. Energy is released in the absence of oxygen. The end products are energy, carbon dioxide and water.
