This is a geometric progression with 7 as the initial term and 2 the common ratio. 
<span>The formula to find the nth term is 7 times 2 to the n-1. </span>
<span>For the 10th term, n = 10 so the nth term equals 7 times 2 to the 9th power </span>
<span>or 7 * 2**9 = 7 times 512 which equals 3584. </span>
<span>Of your choices given above, the last one seems closest. </span>
<span>Hope this answers your question!</span>

Michelle wants to make a long-term investment. She wants to triple an initial investment of
UNO [17]

Answer:

It will take approximately 17 years

Step-by-step explanation:

Let the initial investment be x

The investment plus the principal yields 3x

The interest is thus 3x-x = 2x

Formula for simple interest is;

I = PRT/100

R is rate = 12%

T is time = ?

x =$2,000 which is the principal

2x = x * 12 * T/100

2 = 12t/100

12t = 200

t = 200/12

t = 16.67 which is approximately 17 years

In a class, the ratio of girls to boys is 2:3. If there are 30 students in the class, what is the number of boys?
loris [4]
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
