I think you forgot to attach the tree diagram along with the question. I am answering the question based on my research. "Writing the results from a choice of 2 types of bread, 2 meats, and 2 cheeses" is the one description that <span>matches the sequence of events shown in the tree diagram below. The correct option is option "A".</span>
Answer:
195 mL of the 90% solution
Step-by-step explanation:
Let the number of mL of 90% mixture = x
Hence, our equation is
780mL × 15% + x mL × 90% = (780mL + x) 30%
117 + 0.9x = 234 + 0.3x
Collect like terms
0.9x - 0.3x = 234 - 117
0.6x = 117
x = 117/0.6
x = 195 mL
Therefore, You will need 195 mL of the 90% solution
let me know if the propositions they gave don't match with mine.
thanks
Answer:
40 cm
Step-by-step explanation:
This is because the angle opposite the x is equal to the angle opposite the 40 cm making the sides equal as well.
Answer:
is already at its simplest form
Step-by-step explanation:
You cannot factor or GCF anything out of it, and you cannot just subtract exponents. Therefore, it is simplified already.
