Change the fraction to a improper fraction.

11/9 + 10/9

Since they have the same denominators you can add them.

11/9 + 10/9 = 21/9

The answer is 21/9

Hope this helps :)

You need to change the fraction into a improper fraction by multiplying the one by the nine and assuring to then repeat for the second one but instead of adding 2 add one. Then make sure the bottom numbers are the same the add the top numbers together making sure the bottom number is the same. The answer should be 21 over 9

Use The Scale Factor 1:12 To Find The Missing Dimension

adell [148]

Answer:

The length of the model is 21 inches

Step-by-step explanation:

we have

The scale factor

$\frac{1}{12}$

That means

1 unit in the model represent 12 units in the actual

1 inch in the model represent 12 inches in the actual

Remember that

$1\ ft=12\ in$

1 inch in the model represent 1 ft in the actual

The scale factor is

$\frac{1}{1}\ \frac{in}{ft}$

therefore

21 ft in the actual represent 21 inches in the model

nordsb [41]

Answer:

$\$164.5$

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

$i=\dfrac{P\cdot r\cdot r}{100}$

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

$i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5$

So the total amount will be,

$=\text{Principal}+\text{Interest}$

$=70+94.5$

$=\$164.5$

Arada [10]

Answer:

25, 34, 43

Step-by-step explanation:

-11 + x = -2, -11 + 9 = -2 -2 + x = 7, -2 + 9 = 7, 7 + 9 = 16 -2 - x = -11, -2 - 9 = -11 7 - x = - 2, 2 + x = 11, 11 - 2 = 9, 9 = x 7 - 7 = 0 - 2 = -2, 7 + 2 = 9, 7 - 9 = -2

16 + 9 = 25, 25 + 9 = 34, 34 + 9 = 43

J'espère que cela pourra aider : )

red marbles = 1/8 *56 = 7

There are 7 red marbles
