Answer:
122.5
Step-by-step explanation:
Let the student normal score be 100
In the beginning score increased by 40%
Hence score at the beginning =100+40 = 140%
Now before end score decreased by 25%
Decrease = 25% of 140 = 35
Hence score at the end of month = 140-35 = 105
Average score for the month
= Total of scores of end and beginning month /2

Answer:
2.40 × 10²
Step-by-step explanation:
Data provided in the question:
we have to convert 820,000 Btu/h to kW
Now,
1 kW = 3412.142 Btu/h
or we can say
1 Btu/h = 0.00029307107 kW
Therefore,
820,000 Btu/hr in kW will be
= 820,000 × 0.00029307107 =
or
= 240.3182774
or
= 2.40 × 10²
Hence,
according to the question, X will be 2.4 and the term in the power of 10 is 2
