Which equation applies the associative property?

Artyom0805 [142]

The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.

Work out the percentage change to 2 decimal places when a price of £125.99 is increased to £150.

gizmo_the_mogwai [7]

Answer:

Percent change is 19.06%

Step-by-step explanation:

It is given that:

Price before change = £125.99

Price after increase = £150

Change = 150 - 125.99 = £24.01

Percent of change = $\frac{Change}{Price\ before\ change}*100$

Percent of change = $\frac{24.01}{125.99} * 100$

Percent of change = 0.1906 * 100

Percent of change = 19.06%

Therefore,

Percent change is 19.06%

Ainat [17]

Answer:

$\bold{2\sqrt{3} ~is~irrational.}$

Step-by-step explanation:

Hi there!

$\bold{2\sqrt{3} }$ is an irrational number.

Now, what is an irrational number? An irrational number is a number that goes on for ever.

Examples: $\bold{\pi ,\sqrt{2} , \sqrt{3} ....}$

$\bold{\sqrt{3} }$ is a surd (an irrational square root)

If we multiply 2 times $\bold{\sqrt{3} }$ , we will get an irrational number.

Thus, $\bold{2\sqrt{3} }$ is an irrational number.

Hope it helps! Enjoy your day!
