The associative property will be:

(14\textbf{.}\frac{1}{7})\frac{2}{5}

So, Option C is the correct option.

Can the side lengths 12,15, and 13 form a triangle?​
Fantom [35]

Answer:

Yes

Step-by-step explanation:

It is a Pythagorean Triple. A Pythagorean Triple is the sides of a triangle that fit perfectly into the Pythagorean Theorem, which is:

a²+b²=c²

12, 13, and 15 are numbers that you should know off the top of your head so if you see a triangle with 2 of those numbers, you instantly know the 3rd number.

As a<br>Scientific notation<br>Express this number in standard form.<br>1.304 x 107 = ?​
aivan3 [116]

Answer:

13 040 000  

Step-by-step explanation:

To convert the scientific notation of a large number to a decimal number, move the decimal point as many places to the right as indicated by the exponent of 10.

Use zeros for placeholders as needed.

Move the decimal point seven places to the right

1.304 × 10⁷ = 13 040 000

We had to insert four zeros as placeholders.

1.304 × 10⁷ = 13 040 000
