A light bulb consumes 3600 watt-hours in 3 days and 18 hours. How many watt-hours does it consume per day?
Tasya [4]

18 hours = 18/24  reduces to 3/4 of a day

3/4 = 0.75

so 3600/3.75 = 960 watts per day

Which equation is correct
Anika [276]

For this case we have to define trigonometric relations of rectangular triangles that:

  • The cosine of an angle is given by the leg adjacent to the angle on the hypotenuse of the triangle.
  • The sine of an angle is given by the leg opposite the angle on the hypotenuse of the triangle.

Then, according to the figure we have:

Sin (G) = \frac {15} {17}\\Cos (G) = \frac {8} {17}

Answer:

Sin (G) = \frac {15} {17}

Option D

Abdullah and Kanna are working on the same problem.
Leona [35]

Answer:

Abdullah is correct.

Step-by-step explanation:

The bottle contained originally 12 fl oz, so 12 fl oz is 100%.

The box now contains 20% more, so now it contains 120% of 12 fl oz.

120% * 12 fl oz = 1.2 * 12 fl oz = 14.4 fl oz

Also, 20% is 1/5. Abdullah divided 12 oz into 5 equal parts, and then he added one more 1/5. He interpreted the problem correctly. The amount in the new bottle is the amount of the old bottle plus 20% of that old amount.

Kanna considers the original amount to be 80%. When he adds another 20%, he is adding 1/4 of 12 which is too much. That is why he gets an incorrect answer that is to high. He interpreted the problem incorrectly. For him, the old bottle has 20% less than the new bottle. That is incorrect.

Abdullah is correct.
