Answer: A) 0.625 Explanation: 5/8 is Nothing but to divide 5 into 8 parts.     As 5 is smaller than 8, the quotient starts with a decimal point to make 5 as 50 to be divisible by 8. (0.)     Now 50 goes for 6 times in 8 leaving a remainder 2. (0.6)      Again 2 is smaller than 8, As it already has decimal point in the quotient, now 2 becomes 20.      Now 20 goes for 2 times in 8 leaving a remainder 4. (0.62)      Again 4 is smaller than 8, As it already has decimal point in the quotient, now 4 becomes 40.     Now 40 goes for 5 times in 8 leaving a remainder 0. (0.625)     Therefore, the decimal value of 58 is 0.625.   Now find a decimal value of 1117 and Discuss your at Discuss.

Explanation :

Answer: C) Both A & B Explanation: Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source. Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal). Geothermal power plants require high-temperature (300°F to 700°F) hydrothermal resources that come from either dry steam wells or from hot water wells.
