something is wrong with your question bc 690 plus 575 equals to 1265
Answer:
![\approx \frac{11}{40}](https://tex.z-dn.net/?f=%5Capprox%20%5Cfrac%7B11%7D%7B40%7D)
Step-by-step explanation:
Juice squeezed from first orange =
= 0.235
Juice squeezed from second orange =
= 0.3
Juice squeezed from third orange =
= 0.45
Juice squeezed from fourth orange =
= 0.27
Juice squeezed from fifth orange =
= 0.47
Total juice squeezed from all the five oranges = 0.235 + 0.3 + 0.45 + 0.27 + 0.47 = 1.725
Total juice to be squeezed = 2 cups
More juice required = 2 - 1.725 = 0.275 ![\approx \frac{11}{40}](https://tex.z-dn.net/?f=%5Capprox%20%5Cfrac%7B11%7D%7B40%7D)
Therefore, to make it 2 cups of orange juice for the family, about
cups of more juice is required.
The answer to this is 10 39/88.
Sin (a+b) = sin a. cos b + cos a. sin b
a= 50° and b=40°, then
sin(50+40) = sin 50° . cos 40° + cos 50° . sin 40°
sin(50+40) = sin 90° = 1 and
sin 50° . cos 40° + cos 50° . sin 40° = 1
