The length of a rectangle is seven inches more than its width. Its area is 78 square inches. Find the width and length of the re
Alekssandra [29.7K]

Answer:

Length: 23.38

Width: 3.34

Step-by-step explanation:

First I drew out a diagram so that I could visibly see the problem. [ a rectangle with 7x on one side and x on the other.

So to find the area you multiply length time width and 7x times x is 7x^2. The actual area is given: 78, so you set that equal to 7x^2.

Then you want to divide by 7 to get 11.14. Then you want to take the square root of 11.14 to get 3.338 which rounds to 3.34 {try not to round until the very end]. This gives you the width of the rectangle, so to find the length you would have to multiply x by 7 to get 23.38. When you multiply the length and width (3.34 x 23.38) you get 78.08 which can round to 78.

7x^2 = 78

x^2 = 78/7

x^2= 11.142...

x = sqrt(1.142...)

x = 3.338 --> 3.34 --> width

3.34 x 7 --> 23.38 --> length

3.34 x 23.38 --> 70.8

Find the sum of the first six terms of a geometric progression .​
Dominik [7]

Question:

Find the sum of the first six terms of a geometric progression.

1,3,9,....

Answer:

S_6 = 364

Step-by-step explanation:

For a geometric progression, the sum of n terms is:

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

In the given sequence:

a = 1

r = 3/1 =3

n = 6

So:

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

S_6 = \frac{1 * (3^6 - 1)}{3 - 1}

S_6 = \frac{3^6 - 1}{2}

S_6 = \frac{728}{2}

S_6 = 364
