Find the comthon ratio of the geometric sequence 10,60, 360,...

Answers

Answer:

10

Step-by-step explanation:

The common ratio of the geometric sequence 10,60, 360,... is 6.

What are arithmetic and geometric sequence?

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, A geometric sequence 10,60, 360,...

We know the common ratio r in a geometric sequence is

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Therefore,

The common ratio in this geometric sequence  10,60, 360,... is,

= 60/10 = 360/60 = 6.

So, The common ratio is 6.

Answers

Answer:

-6

Step-by-step explanation:

Answer:

-6/1 or just -6

Step-by-step explanation:

15/4 ÷ (-5/8) is -6/1 .

Find the reciprocal of the divisor

Reciprocal of (-5/8) : (-8/5)

Now, multiply it with the dividend

So, 15/4 ÷ (-5/8) = 15/4 × (-8/5)

= 15 × (-8)  = -120

   4 × (-5)   =  -20

After reducing the fraction, the answer is -6/1 or just -6.

How can you solve linear equations by combining like terms?

Answers

Answer: In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz² and −5xyz² are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all constant terms are like terms.

I HOPE THIS HELPED ! :) mark me brainlist pls

Answer:

by combining them like the ordinary like ordinary integers.

Step-by-step explanation:

For example we have

8x + 4y = 3x - 6

you will bring 3x to the left so it will become -3x

8x - 3x + 4y = -6

then combine like terms

there you have

5x + 4y = -6

The given:

8x + 4y = 3x - 6

8x - 3x + 4y = -6

5x + 4y = -6

answer for the example: 5x + 4y = -6

for a repair job an electrician charges an hourly rate of d dollars plus a flat fee of 50 the electricion charged a total if 114 for a 4-hour repair job. Part B. What is the value of D

Answers

Answer:

B. 4d + 50 = 114

Step-by-step explanation:

Given parameters:

Hourly rate = $d/hr

Flat fee = $50

Charge for the 4hrs = $114

Number of hours = 4hrs

To find d;

    Total cost  = $114;

             $114  = Flat fee + (rate per hour x number of hours)

            $114 = $50 + 4d

The value of d can be calculate using;

           4d + 50 = 114

The value of d is 4d + 50 = 114

A food bank sends a truck with 400 pounds of food pantries every week, and receives a government surplus shipment of 3,200 pounds every other week. If it has 10,000 pounds of food on hand at the beginning of July, how much will it have six weeks later?

Answers

I’m pretty sure the answer would be 22,000 considering that have 10,000 pounds of food on hand, and every other week they receive 3,200 pounds of more food so that would be 3x 3,200= 9,600 because that is half of 6 weeks and every week of six weeks they receive 400 pounds of more food so 6x400 = 2,400
9,600+2,400=12,000 + 10,000 =22,000 pounds of food.

D) no solution

Answers

Answer:

no solution

Step-by-step explanation:

[1]    6x - 9y = 16

  [2]    2x - 3y = 7

// Solve equation [2] for the variable  x  

 [2]    2x = 3y + 7

 [2]    x = 3y/2 + 7/2

// Plug this in for variable  x  in equation [1]

  [1]    6•(3y/2+7/2) - 9y = 16

  [1]    0 = -5 =>  NO solution

According to a certain country’s department of education, 40.0% of 3-year-olds are enrolled in day care.

What is the probability that a randomly selected 3-year-old is enrolled in day care?

Answers

Given parameters:

Percentage of enrollment of 3-year-olds = 40%

Unknown:

Probability that a randomly selected 3-year-old is enrolled in a day care = ?

Probability is the likelihood of an event to occur.

   Probability  = [tex]\frac{Possible outcome}{Total out come}[/tex]

In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.

  We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.

The possible enrollment is 40 and the total is 100;

Input the parameters and solve;

      Probability  = [tex]\frac{40}{100}[/tex]   = [tex]\frac{2}{5}[/tex]

The probability that any randomly selected 3 year old is enrolled in day care is [tex]\frac{2}{5}[/tex]
