Answer:
a) 13 cups
b) 1 .6kg
Step-by-step explanation:
a) 25 / 1.8 = 13.89
13 cups
to check the answer:
13 cups x 1.8kg per cup = 23.4kg in total
we can use 23.4 to figure out b
b) 25 kg - 23.4kg = 1.6kg
1.6kg

Answer:
432
Step-by-step explanation:
b x h (base x height)
the base is 27 yards and the height is 16.
27 x 16 = 432
Answer:
13 songs .
Step-by-step explanation:
The total number of songs recorded =
16 + 62.5 % of 16
= 16 * 1.625
= 26.
if 50% are removed the 26-13 = 13 songs are in the final album.
#3 sin(x) = -sqrt(2)/2 so x = 315 degrees. So we have sin(x+pi/3) = sin(375) = sin(15) which in exact form would be (sqrt(3) -1)/(2sqrt(2))
#4 to find x we take the arctan(20/21) which is approximately 43.6 degrees and add 180 to it since it's in the 3rd quadrant which is 223.6 degrees so we do sin(223.6 + 90) = sin(313.6) which equals -21/29. This can also be done with the pythagorean theorem. -21/29.
#5 13^2 - 5^2 = 12^2. so sin is -12/-13 = 12/13. we take arcsin of that and add 180 and then divide by 2 and take the sin of that and its approximately 3/sqrt(13).
#6 sin is 4/5 so we take arcsin of that and get 143.13 which -60 is 83.13 and we take the sin of that to get 3/10 + 2sqrt(3)/5
Hope this helped :L
