Write an explicit formula for a-n, then term of the sequence 36, 39, 42,....

Answers

Answer:

a^n = 36 + (n-1) * 3

Step-by-step explanation:

Explicit formula for arithmetic sequences: a^n = a^1 + (n-1) * d

In this case, a^1 = 36 and common difference/d = 3

So...

a^n = 36 + (n-1) * 3 is the explicit formula for this sequence.

Answer:

3x + 2 4 5x

Step-by-step explanation:

The solution of the equation formed 3x + 5x = 4 - 2 will be; x = 1/4.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

We have given that sum of 3 times the value of x and 2 is equal to 4 less than 5 times the value of x then;

The sum of 3 times the value of x and 2 means (3x + 2)

4 less than 5 times the value of x means (4 - 5x)

Therefore, the equation would be;

3x + 2 = 4 - 5x

Now solving for x;

3x + 5x = 4 - 2

8x = 2

x = 1/4

Hence, the solution of the equation formed 3x + 5x = 4 - 2 will be; x = 1/4.

You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.The probability of choosing an odd number and then a 20

Answers

Answer:

P odd number, then 20) = 1 /14

Step-by-step explanation:

P( odd number) =  number of odd numbers/ total

number of odd numbers = 3

total = 7

P( odd number)   = 3/7

We keep the tile so that there are only 6 tiles left

P (20) = number of 20/ total

         = 1/6

We multiply the probabilities together

P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14

Mia has 4 horses and 11 apples. She gives each horse the same number of
apples, and she uses as many apples as she can. How many apples does Mia
give each horse? How many apples are left?
» Complete the equation.
11 : 4 =
R

Answers

Answer:

She gives 2 apples to each horse, and there will be 3 apples left.

Step-by-step explanation:

We know that Mia has 4 horses and 11 apples

She gives each horse the same number of apples, such that she uses the maximum number of apples that she can.

If she has 4 horses and she gives the same amount to each horse (let's say that this amount is N apples to each horse)

Then she uses a total of 4*N apples.

Then if N  =  1, she needs 4*1 = 4 apples.

if N = 2, she needs 4*2 = 8 apples.

if N = 3, she needs 4*3 = 12 apples.

But she has only 11 apples, so she can not give 3 apples to each horse.

Then the maximum number of apples that she can give to each horse is N = 2, 2 apples to each horse.

Now, we know that she has 11 apples in total, and she gives 2 to each of the 4 horses, then she gives:

4*2 = 8 apples.

The number of apples that are left are:

11 - 8 = 3

There are 3 apples left.

In 45 years will be 4 times older how old is she now

Answers

Answer and Step-by-step explanation:

The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.

 

       current age     future age

        x                    x+45

 

The future age is 4 times current age

 

x+45 = 4x

   45 = 3x

   15 = x

 

She is currently 15. 45 years from now she will be 60.

60 is 4 times her current age. So right now, she is 15.
