There are 15 girls and 18 boys. Therefore, the ratio of girls to boys in the cafeteria is 15 : 18 (or 15/18). However, both sides can be divided by 3, which simplifies the ratio to 5 : 6 (or 5/6).

Hope this helps!! :)

Answer: The ratio would be 5 girls to every 6 boys.

Step-by-step explanation:

Find a common number both can be divided be which would be 3, so 15 by 3 is 5, and 18 by 3 is 6. So, there is 5 girls for every 6 boys which is the ratio.

2d is cancelled

3d+4d=9d-16

7d=9d-16

16=9d-7d

16=2

Find the sumofthe geometrical progression of five terms, of which the first term is 7 and the multiplier is 7.Verify that the su
777dan777 [17]

Answer:

The sum of first five term of GP is 19607.

Step-by-step explanation:

We are given the following in the question:

A geometric progression with 7 as the first term and 7 as the common ration.

a, ar, ar^2,...\\a  = 7\\r = 7

7, 7^2, 7^3, 7^4...

Sum of n terms in a geometric progression:

S_n = \displaystyle\frac{a(r^n - 1)}{(r-1)}

For sum of five terms, we put n= 5, a = 7, r = 7

S_5 = \displaystyle\frac{7(7^5 - 1)}{(7-1)}\\\\S_5 = 19607

The sum of first five term of GP is 19607.

Verification:

2801\times 7 = 19607

Thus, the sum is equal to product of 2801 and 7.
