a photo masured 15cm by 10cm andbis put in a frame that measures 25cm by 20cm calculate the are of the space between the photograph and the frame

Answers

The frame is 25x20cm, meaning hat it has an area of 500. The photo is 15x10, meaning it has an area of 150. Therefore, if you subtract the areas (500-150) you get an area between the photograph of 350 cm squared.

the common ratio of a geometric series is 3 and the sum of the first 8 terms is 3280. what is the first term of the series?

Answers

Answer: 1

Step-by-step explanation:

The formula for calculating the sum of a Geometric series if the common ratio is greater than 1 is given as :

$S_(n)$ = $(a(r^(n)-1) )/(r-1)$

Where $S_(n)$ is the sum of terms , a is the first term , r is the common ratio and n is the number of terms.

From the question:

$S_(n)$ = 3280

a = ?

r = 3

n = 8

Substituting this into the formula , we have

3280 = $(a(3^(8)-1) )/(3-1)$

3280 = $(a(6561-1))/(2)$

Multiply through by 2 , we have

6560 = a ( 6560)

divide through by 6560, we have

6560/6560 = a(6560)/6560

Therefore : a = 1

The first term of the series is thus 1

ANSWER: The number is 10.
Hope this helps!!

I used the variable n as the number we needed to find. The equation was n + 8 + 12 = 3n
