Using Pythagorean theorem (a^2+b^2=c^2)
15^2+20^2=c^2
225+400=c^2
625=c^2
Square root to get c alone

In the diagram, point X is the centroid. If<br> EX=8, what is the length of XC ?
Phoenix [80]

Answer:

16

Step-by-step explanation:

If X is the centroid that means that EC is a median along with the other lines that intersect inside the triangle. Medians drawn from a triangle have a special rule; this rule is that all medians have a 2:1 ratio between the different sections of one median. For example, EC is one median with the two sections XC and EX. Therefore XC and EX have a 2:1, with the 2 representing the longer section closest to the vertex. This means that XC is double EX, so to find XC simply double EX measurement, which is 8. So XC must equal 16.

Which of the following has a value this is less than zero? A:(-6)^2 B:1/3 x 2 C:0.5^2 D:-7^2
solniwko [45]

The value of -7² is less than zero which is the correct answer would be an option (D)

<h3>What is the fraction?</h3>

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

To determine the value is less than zero

Option A: (-6)² ⇒ 36

So this value is greater than zero

Option B: 1/3 × 2 ⇒ 2/3

So this value is greater than zero

Option C: 0.5² ⇒ 0.25

So this value is greater than zero

Option D: -7² ⇒ -49

So this value is less than zero
