What is geometrical series?

A geometric series is the sum of an unlimited number of terms with a fixed ratio between them.

Option A: You receive 1¢ on the first day, 3¢ on the second day, 9¢ on the third day, 27¢ on the fourth day, and so on, tripling each day.

The sum of money till the 10th day will be

= a(rⁿ-1)/(r-1) = 1(3¹⁰-1)/(3-1) = 29,524¢ = $295.24

Option B: You receive $100 each day.

The sum of money till the 10th day will be = 10×$100 = $1,000

Hence, the second option is more profitable.

Step-by-step explanation:

First, we break the rhombus down into similar shapes,

The area of 2 triangles = The area of a square

So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,

10 multiplied by 5 =50

Thats the area of rectangle 1

Rectangle 2

A container is shaped like a rectangular prism and has a volume of 72 cubic feet. Give four different set of measurements that could be the dimensions of the container.

Need the answer to all dem ASAP!!!

Answers

Answer:

The formula for the volume of a prism is V = Bh

where,

B is the base area

h is the height.

Since, the base of the prism is a rectangle, therefore, volume of a rectangular prism = (L * B) * h

Assumptions:

Length, L and Width, B cannot be the same.

1.

h = 4 ft

B = 2 ft

L = 9 ft

2.

h = 4 ft

B = 3 ft

L = 6 ft

3.

h = 6 ft

B = 2 ft

L = 6 ft

4.

h = 2 ft

B = 2 ft

L = 18 ft
