Answer:

6.

Step-by-step explanation:

2.3 repeating = 2 1/3

So 3 2/3 + 2 1/3

= 5 + 1

= 6.

Answer: 6

Step-by-step explanation:

3\frac{2}{3}+2.3^-

Let's begin by converting the repeating decimal to a fraction and then to a mixed number.

Take the number:

2.3^-

Let x (our result) be equal to that number.

x=2.3^-

Multiply by 1 followed by as many zeros as repeating decimals; in this case 1. Therefore, 10.

10x=2.3^-*10

This basically moves the decimal point one number to the right and since we have infinite 3's, we simply move 1 three and add another.

10x=23.3^-

Subtract this and the original equation (x=2.3^-)

10x=23.3^-\\-x=2.3^-

-----------------

10 - 1 = 9 and we have the same infinite repeating number 3, therefore they cancel out, leaving 23-2 = 21

9x=21

Divide by 9

x=\frac{21}{9}

Simplify by 3.

21/3=7

9/3=3

x=\frac{7}{3}

Now, convert to a mixed number. To do this, divide.

7/3=2

6

-------

1

The 2 is the whole number, 1 is the numerator and 3 the denominator.

2\frac{1}{3}

------------------------------------------------------------------------------------------------

Now we can solve this;

3\frac{2}{3}+2\frac{1}{3}

Add the whole numbers and the fractions separately.

(3+2)+(\frac{2}{3}+\frac{1}{3})

5\frac{3}{3}

3 and 3 can be simplied.

3/3=1

3/3=1

5\frac{1}{1}

The result is 1, add this to the 5.

5+1=6

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.
tia_tia [17]
<h3>Answer:  6.93</h3>

Work Shown:

Use the pythagorean theorem to find x

a^2 + b^2 = c^2

x^2 + 11^2 = 13^2

x^2 + 121 = 169

x^2 = 169 - 121

x^2 = 48

x = sqrt(48)

x = 6.92820323027551

x = 6.93

Let's try an make a formula to make things easy.

_________________________________________________

Look at Andrew's pattern, it goes up 6 every time. Lets look at the 6 times table

6 times table:           6, 12, 18, 24, ...

____________________________________

First think, how would you work out the <u>7</u>th term in the <u>6</u>th times table?

You would do <u>6</u> times <u>7</u>.

So the formula for the 6th times table is:

6n     (where n is the term you want to find out)

_______________________________________

So to get the 9th term in the 6 times table, you would replace the n with 9, like so:

9th term in 6 times table = 6 x 9 = 54

______________________________________

Now lets compare the 6 times table to Andrew's pattern:

6 times table:           6, 12, 18, 24,

Andrew's pattern:     3, 9, 15, 21,

_____________________________________

If you look, you can see that Andrew's pattern is the 6 times table minus 3!

So what would be the formula for Andrew pattern?

---> it would be:  6n - 3   (since it's the 6 times table but minus 3)

_____________________________________

We can use this formula to easily work out the 20th term in Andrew's pattern!:

20th term = 6 x 20 - 3 = 120 - 3 = <u>117</u>    (remember, replace the n with 20)

______________________________________

Now let's make a formula for Ben's pattern!

Ben's pattern goes up in 5s, so lets compare it to the 5 times table:

5 times table:       5, 10, 15, 20

Ben's pattern:       3, 8, 13, 18,

The formula for the 5 times table is 5n, and Ben's pattern is the 5 times table but minus 2.

So the formula for Ben's pattern is: 5n - 2

__________________________________

<u>Now swap out the n for 20</u>  (to get the 20th term):

20th term = 5 x 20 - 2 = 100 - 2 = <u>98</u>

_________________________________________

So Andrew's 20th term is <u>117</u>, and Ben's 20th term is <u>98</u>.

All we do now is subtract them to find the difference:

117 - 98 = <u>19</u>

- - - - - - - - - - - - - - - - - - - - - - - - -

Answer:

Ben's 20th term is smaller by 19!

- - - - - - - - - - - - - - - - - - - - - - - - - -

What is the simplified polynomial and the value
Elanso [62]

The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186

From the polynomial given;

  • x²yxy -xy²xy +xy.

The polynomial can be factorised to yield a simpler form as follows;

  • xy(x²y - xy² +1).

This is so because, xy is a common factor.

The value is therefore;

  • (-3×2)((-3)²2 - (-3×2²) +1)

  • -6(18+12+1)

= -186

Two dressmakers, Sue and Anne, sewed costumes for a local theater production. Sue sewing alone for 10 hours sewed some of the co
crimeas [40]

Answer:

Sue would have taken 15 hours to sew all the costumes.

Step-by-step explanation:

In 10 hours, Sue sewed 5 costumes (1 every 2 hours).

Sue= 5 costumes

Sue sewed in 10 hours, twice as many costumes as Anne in 16 hours. Then 5 is twice costumes than Anne produced. Therefore, Anne sewed 2.5 costumes.  

Anne: 2.5 costumes  

In total they had to sew 5+2.5= 7.5 costumes. Then Sue would have taken 7.5*2= 15 hours to sew them all.
