Answer:
Half of each day is taken up by sleeping and eating.
Step-by-step explanation:
Since none of the terms have the same variables the like terms would be (A) because they are both constants
Answer:
The answer is D.
Step-by-step explanation:
40.5 multiplied by 21 is 850.5
so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
Please refer to the other post you saw.
Josh's estimate IS reasonable because when you have a number 5 or above after the decimal, you round up. Although it's reasonable to round up to 5 pounds, the actual amount is 4.5 pounds, or four and a half.
