Answer:

Step-by-step explanation:
From the question we are told that
5% solution of dextrose sugar in water
20% solution of dextrose in
100 milliliters of distilled water water
Generally in mathematically solving we call A the amount of D20W added
Since 20% of dextrose is needed

Total quantity after addition (100+x)
for DW5% total solution is


Mathematically




Therefore the required quantity 
Answer:
Option D Both students could be correct. Because the numbers are given in the original sequence, it is possible to find a common difference and common ratio between the successive terms.
Step-by-step explanation:
A geometric sequence has a common ratio. Here, that ratio would be 11/-5.5 = -2 if the sequence is geometric. That ratio would mean the next two terms are ...
11 × -2 = -22
-22 × -2 = 44
__
An arithmetic sequence has a common difference. Here, that difference would be 11 -(-5.5) = 16.5 if the sequence is arithmetic. That difference would mean the next two terms are ...
11 +16.5 = 27.5
27.5 + 16.5 = 44
__
These descriptions match those offered by the students, so both could be correct.

Answer:

Step-by-step explanation:
We are asked to find the product of
and
.
Upon writing our expression as a product we will get,

Let us convert our given mixed fractions to improper fractions.
Upon cancelling out 3 from our given expression we will get,
Upon dividing -7 by 2 we will get,

Therefore, our expression simplifies to -3.5.
