The correct answer is C.

Triangle inequality means 2 sides of the triangle added up must be longer than the remaining side. Therefore, to find the correct answer quickly, we can add up the shortest 2 sides and see if they exceed the remaining side.

For A,
5 + 4 = 9
9 < 10
Therefore, A is incorrect.

For B,
5 + 7 = 12
12 < 13
Therefore, B is not correct.

For C,
7 + 3 = 10
10 > 9
C is the correct answer.

Heres D, to make sure the answer C is correct.
4 + 5 = 9
9 < 10
D is not correct.

Let's add up the remaining sides to make sure C completely satisfies the rule.

9 + 3 = 12
12 > 7
7 + 9 = 16
16 > 3

Therefore, the answer is C.

I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.

Hope this helps!:)

<span>Alice Correa bought three yards of cloth to make a dress
The cloth was on sale for 1.93 per yard.
Now,  how much did Alice pay for the cloth if the sales tax was 5%.
Let’ solve for the answer
=> 3 yard of clothes were both.
=> Price of clothes are 1.93 dollars per yard
=> then another sales tax is added which is 5%
=> 3 yards * 1.93 dollars = 5.79 dollars
=> 5.79 dollars * .05 = 0.2895
=> 5.79 + 0.2895
=> 6.08 dollars.
