Answer:
Compound interest is the best.
Step-by-step explanation:
Simple interest is that which is not added to the initial capital once the term of the investment or credit has expired.
Compound interest is that which is added to the initial capital at the end of the investment or credit.
Simple interest:
I= C x i x t
15,000 * 0.05 * 5 = $ 750
Compound interest:
Cf= Ci (1+i)ᵗ
Cf = 15,000 * (1.039)^5 = $ 18,162.22
So, if Cf - Ci = I -> 3,162.22 is the compound interest.
X - Columbian coffee ( in pounds),
y - Brazilian coffee ( in pounds );
x + y = 100
8.85 x + 3.85 y = 6.55 ( x + y )
----------------------------------------
x = 100 - y
8.85 ( 100 - y ) + 3.85 y = 6.55 * 100
855 - 8.55 y + 3.85 y = 655
- 5 y = - 230
y = ( - 230 ) : ( - 5 )
y = 46
x = 100 - 46
x = 54
Answer: 54 pounds of Columbian coffee and 46 pounds of Brazilian coffee should be used.
Answer:
x=2
Step-by-step explanation:
So if the equation is -12+7x=x, you need to subtract 7x, because you want to know the value of x. So the equation now looks like this: -12=-6x
you divide-6 to both sides because we want to iscolate the x
The answer is x=2
Hope it helps!
Answer:
9
Step-by-step explanation:
Subtract 1 2 12 12 from both sides of the equation + 1 2 = 2 1 + 1 2 − 1 2 = 2 1 − 1 2 2 Simplify Solution = 9
Each letter of the alphabet is worth two times as much as the one before it, implying that the value of each letter rises in mathematical progression. The formula for finding the nth term of an arithmetic progression would be used. I am written as
a + (n - 1)d = Tn
Where
The number of terms in the arithmetic sequence is represented by n.
The common difference of the terms in the arithmetic sequence is represented by d.
The first term of the arithmetic sequence is represented by a.
Tn stands for the nth word.
Based on the facts provided,
n = 26 characters1 Equals a
3 minus 1 equals 2 (difference between 2 letters)
Therefore,
1 + (26 - 1)2 = T26
51 = T26
The formula for calculating the sum of an arithmetic sequence's n terms
is as follows:
[2a + (n - 1)d] Sn = n/2
As a result, S26 is the sum of the first 26 terms.
S26 = 20/2[2 1 + (26 - 1)2] S26 = 20/2
[2 + 50] S26 =
676 = S26 = 13 52
