Answer:
Friday's drink will taste more like soda and Saturday's drink will taste more like orange juice.
Step-by-step explanation:
Not sure if this is the exact answer you want, but we can use fractions to determine how much one drink tastes compared to the other.
For Sam's Friday drink, we see that he makes 7 liters of orange soda by mixing 3 liters of orange juice with 4 liters of soda. As such, we know that 
and 
.
For Sam's Saturday drink, we can also approach it the same way: the drink has 
and 
Now, we can just compare the fractions with each other:
> and
> .
So we know that the Saturday drink will probably taste more like orange juice than the Friday one. Conversely, we know that the Friday drink will probably taste more like soda than the Saturday one.
The sum of the first eight terms of the geometric sequence whose first term is -2.5 and ratio is 2 is: -637.5
The nth term of a geometric sequence is given mathematically as;
T(n) = ar^n
- where, a = first term of the geometric sequence.
- r = common ratio of the sequence
- and n = nth term of the sequence.
Therefore, the sum of the first 8 terms of the geometric sequence is;
- <em>S(8) = a + ar + ar² + ar³ + ar⁴ + ar⁵ + ar⁶ + ar⁷.</em>
In essence;
- since common ratio, r = 2
Therefore, we have;
- S(8) = -2.5(1 + 2 + 2² + 2³ + 2⁴ + 2⁵ + 2⁶ + 2⁷)
S(8) = -637.5.
Therefore, the sum of the first eight terms of the <em>geometric sequence</em> whose first term is -2.5 and ratio is 2 is: -637.5
