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.

Answers

Answer:

The diagonal is 8.9 feet.

Step-by-step explanation:

Answer:

The diagonal is 8.9 feet

Step-by-step explanation:

The formula for a diagonal of a rectangle is √w^2+h^2, with w and h being the width and height. Plug in your numbers to get √7^2+5.5^2. Simplify that into √49+30.25, then to √79.25. Use your calculator to get 8.9022.

The diagonal is 8.9 feet.

I think the answer is a just from looking.
could you put a picture with the ruler next to all three sides please

You are flying from Houston to Chicago. You leave Houston at 7:30 A.M. At 8:35 A.M. you fly over Little Rock, a distance of 455 miles.

27. Write a linear equation that gives the distance in miles, y, in terms of time, x. Let x represent the pumber of minutes since 7:30 A.M.

28. Approximately what time will you arrive in Chicago if it is 950 miles from Houston?

​

Answers

Answer:

For a uniform move, the traveled distance equation is

y = v*x

where "v" is the average speed (or rate), in miles per minute, x is the time, in minutes.

To find "v" from the given data, divide 455 miles by 65 minutes (the flight time between the cities)

v = 455%2F65 = 7 miles per minute.

So, finally, your equation is

y = 7x.

Y = 7x thats itttt omldhdbdbdbdbdbdb

Answers

the answer to the first one is $7.60 because when you add $0.40 with $0.90, you get $1.30. because you have to add this to the money in the piggy bank, you would get $7.60; $6.30 + $1.30

Answer:

1.) 7.60

2.) 3.70

3.) 7.20

4.) 9.20

Step-by-step explanation:

6.30 + 0.40 + 0.90 = 7.60

Barrys has $7.60 total

3.20 + 1.60 = 4.80

8.50 - 4.80 = 3.70

Henrys change is $3.70

1.20 + (1.20 × 5)

1.20 + 6 = 7.20

The bouncy ball and pen cost $7.20 together

Monday: $2.30

2.30 × 3 = 6.9

Tuesday: $6.90

Solve 4 + x > 6. Graph the solution. A)graph1 B)graph2 C)graph3 D) graph4

Answers

Given the inequality expression 4 + x > 6, we need to solve for x and graph the equivalent graph of the function;

Given

4 + x > 6

Subtract 4 from both sides of the inequality

4 + x - 4 > 6 - 4x > 6 - 4x > 2

Next is to graph the solution x > 2 on the number line.

Since the inequality sign is greater than sign, the line arrow will point towards the right of the number line and the circle will be an open circle.
