0.98768834034243
Step-by-step explanation:
Since 81 is smaller than 90, it is located in the first quadrant and in the first quadrant, the values for sin, cos and tan are always positive.
sin(81)= 0.98768834034243
The following questions are related to problems on simple fraction and arithmetic. Hence, the solutions to the questions are as follows :
1.)
Time on mathematics =<em> 1 hour</em>
Time on science homework = <em>7/8</em><em> hours</em>
Total time spent = (1 + 7/8) =
2.)
Total number of students = <em>60</em>
Fraction of girls = <em>3/4</em>
Fraction of boys = 1 - 3/4 = 1/4
Number of boys = 1/4 × 60 = 15 boys
3.)
Initial temperature = <em>- 2°C</em>
Final temperature = <em>8°C</em>
Change in temperature = Final temperature - Initial temperature
Change in temperature = (8 - (-2)) = 8 + 2 = 10°C
4.)
Elevation of everest = <em>20028 feets </em>
Elevation of dead sea =<em> - 485 feets</em>
Difference in elevation = (20028 - (-485)) = 20513 feets
5.)
