Decompose 8/10 in 2 ways

Answers

The decomposition of the fraction A = 8/10 is solved and

a) A = 2/5 + 2/5

b) B = 5/10 + 3/10

What is decomposition of fraction?

A fraction can be expressed as the product of a whole number and a unit fraction. Decomposition of fraction means break down a fraction into smaller parts. The denominator which is the bottom number gives the total number of pieces

Given data ,

To decompose 8/10 in two ways, we need to find two pairs of fractions that add up to 8/10

First way:

We can write 8/10 as 4/5, and then decompose 4/5 into two fractions with a common denominator. One way to do this is to split 4/5 into two equal fractions:

8/10 = 4/5 = 2/5 + 2/5

Another way to decompose 8/10 is to split it into a sum of a whole number and a fraction that is less than 1. We can write 8/10 as 0.8, and then decompose it into 0.5 and 0.3:

8/10 = 0.8 = 0.5 + 0.3

Second way:

We can also decompose 8/10 in a different way. We can write 8/10 as the sum of two fractions with a common denominator, where one of the fractions is a unit fraction (a fraction with a numerator of 1):

B = 5/10 + 3/10

Hence , the decomposition of the fraction A = 8/10 is solved

The first four sequences are shown below 9,5,1,-3 which of the following functions best defines this sequence

Answers

Answer:

Arithmetic sequence.

Step-by-step explanation:

We have been given 9,5,1 and -3

We need to check what kind of sequence is this.

d=a_2-a_1

d is common difference we will check difference of consecutive terms.

5-9=-4

1-5=-4

-3-1=-4

We can see the difference between all the terms are same that is -4

So, this is an arithmetic sequence.

Arithmetic sequence is the sequence in which the difference between consecutive terms are same.

Adele palmer’s charge account statement showed a previous balance of $1,500 , a finance charge of $5, new purchases of $150, and a payment of $80,00 what Is her new balance?

Answers

Answer:

New Balance = $1,575.00

Step-by-step explanation:

We can find Adele's new balance by adding the amounts she is charged to her previous balance and subtracting the amount she has paid so far:

Previous balance = $1,500.00

Finance charge = + $5.00

New purchases = + $150.00

Updated Total = $1,655.00

Payment = - $80.00

New balance = $1,575.00


A football team has four chances with the ball to gain ten yards and keep going to try to make a touchdown. A team gained 7 yards, lost 2, gained 4, and lost 1.

Answers

7 - 2 = 5

5 + 4 = 9

9 - 1 = 8

Sp the total yards they moved was 8 yards.

Hope I helped ya! 
So, if losing yards represented by negatives and gaining yards is represented by positives, the equasion whould look like this:
7+(-2)+4+(-1)

The assosiative property tells us that we can group numbers together, like this:
7+4+(-2)+(-1)

And if it helps, add parentheses like this:

(7+4)+(-2)+(-1)

And solve those first:
(11)+(-2)+(-1)

And solve -2+-1
(11)+(-3)

And that equals:
-8

Hope this helps you out!
