I hope this will help you.
Come on now, check your book on the "product to sum" identities
![\bf cos({{ \alpha}})sin({{ \beta}})=\cfrac{1}{2}[sin({{ \alpha}}+{{ \beta}})\quad -\quad sin({{ \alpha}}-{{ \beta}})]](https://tex.z-dn.net/?f=%5Cbf%20cos%28%7B%7B%20%5Calpha%7D%7D%29sin%28%7B%7B%20%5Cbeta%7D%7D%29%3D%5Ccfrac%7B1%7D%7B2%7D%5Bsin%28%7B%7B%20%5Calpha%7D%7D%2B%7B%7B%20%5Cbeta%7D%7D%29%5Cquad%20-%5Cquad%20sin%28%7B%7B%20%5Calpha%7D%7D-%7B%7B%20%5Cbeta%7D%7D%29%5D)
5 2/3 - 1 1/4
5-2 =3
2/3 - 1/4 = 8/12 - 3/12 = 5/12
answer is 3 5/12
You didn't provide the possible answers, but the smallest length of time will result in the least amount of interest.
Step-by-step explanation:
All you gotta do is multiply all the test amounts by 5 1/2.
If you have a calculator handy, I would change everything to decimals.
So for chopped onions, you would need
1.5 lbs x 5.5 = 8.25 = 8 1/4 lbs of chopped onion.
Chopped green pepper
.5 lbs x 5.5 = 2.75 = 2 3/4 lbs chopped onion.
Carrots
.5 lbs c 5.5 = 3.75 = 2 3/4 lbs carrots
Chopped Celery
4 stalks x 5.5 = 22 stalks of chopped celery.
And so on. I think you can do it from there.
