The second answer. When there is a smaller number above a number, that means how many time you multiply that number by itself!
The second answer because an exponent is the number of times the base is being multiplied by itself.

a triangle has two side lengths of 8.5 centimeters and 9.5 centimeters. What is a possible length for the third side? Explain why this is a possible length

Answers

Answer:

12.7 centimeters

Step-by-step explanation:

Using Pythagorean Theorem,

[tex]a^{2} +b^{2} =c^{2}[/tex]

8.5² + 9.5² = √162.5

√162.5 ≈ 12.7²

The possible side lengths for the third side of the given triangle is x ≤ 18.

What is Triangle?

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given that,

a triangle has two side lengths of 8.5 centimeters and 9.5 centimeters.

We have to find the possible side lengths for the third side.

We know that,

"Triangle Inequality theorem" states that for a triangle, the sum of any two sides will be always greater than or equal to the third side.

Here, sum of first two sides ≥ length of third side

Let x be the third side.

8.5 + 9.5 ≥ x

18 ≥ x

Hence the possible side lengths are x ≤ 18.

Answer:

There are 7340032 zipcodes that can be created without one, three, or five, as the first number.

It is C, x-axis

Step-by-step explanation: if the point is at 0 on the y-axis but on a number greater than or less than 0 on the x-axis then the point is on the x-axis line.

Answer:

Since the y-coordinate is zero, that means that our point lies on the x-axis because any point on the x-axis has a v-coordinate of 0.  Therefore our best option would be option E (x-axis).

The answer is 14,800 square yards.

Step-by-step explanation:

Square Area:bh: 145 x 80 = 11600

225-145=80/2= 40 (the base)

Triangle Area: 1/2 (b) (h): 1/2 (40) (80) = 1600

Since there are 2 riangles multiply 1600 by 2 = 3,200

Add 11600 + 3,200 = 14,800
