Answer:
The surface area of the green prism is 2.5 times greater than the surface area of the blue prism
Answer:
- 273 mL of 5%
- 117 mL of 15%
Step-by-step explanation:
Let q represent the quantity of 15% dressing used. Then the amount of 5% dressing is (390 -q). The amount of vinegar in the mix is ...
0.15q + 0.05(390 -q) = 0.08(390)
0.10q = 31.2 -19.5 = 11.7 . . . . . . subtract 0.05(390) and simplify
q = 117 . . . . . . . . . . . . . . . . . . multiply by 10
390-q = 273
The chef should use 273 mL of the first brand (5% vinegar) and 117 mL of the second brand (15% vinegar).

<em>Additional comment</em>
You may have noticed that the value of q is (0.08 -0.05)/(0.10 -0.05)×390. The fraction of the mix that is the highest contributor is the ratio of the difference between the mix value and least contributor, divided by the difference between the contributors: (8-5)/(15-5) = 3/10, the fraction that is 15% vinegar. This is the generic solution to mixture problems.
I need a photo to tell you the answer
Answer:
it would actually be the opposite because if u multiply ur making the number higher, it can be a fraction but it would be 23/1 and thats a whole number u would need to divide by 100 and 100 bc if 10 u get 2 3/10 and if u divide by 100 u get 23/100 either way u get a fraction but if u divide by 10 u get a mixed fraction. If u just want a fraction u would have to divide from 100
Step-by-step explanation:
the same is for dividing decimals
