The answer is B) 7. PZ is half of PR, which makes RZ half of RP, making RZ also 7.

Answer: B) 7

Step-by-step explanation:

We know that a median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

  • Centroid : A point in a triangle where all the three medians of the triangle meet.

From the given figure, we can see that if C is the centroid of the triangle then QP must be a median of the triangle.

It implies the point Z must be the mid point of the line segment PR .

⇒ PZ=ZR

Therefore, RZ= 7 units .

100 POINTS PLEASE HELP ASAP!!!!<br> Explain the concept of using cancellation to reduce fractions.
Setler79 [48]

Explanation:

A "reduced" fraction is one that has mutually prime numerator and denominator. That is, the numerator and denominator have no common factors.

A fraction is "reduced" by canceling common factors from numerator and denominator. If "a" is a factor common to the numerator and denominator of a fraction, that fraction can be written with "a" canceled from each:

  \dfrac{ab}{ac}=\dfrac{a}{a}\cdot\dfrac{b}{c}=1\cdot\dfrac{b}{c}=\dfrac{b}{c}

Here is a numerical example:

  \dfrac{2}{4}=\dfrac{2\cdot 1}{2\cdot 2}=\dfrac{2}{2}\cdot\dfrac{1}{2}=\dfrac{1}{2}

__

A numerator factor and a denominator factor "cancel" because their ratio is 1, the identity element for multiplication. Anything times 1 is just that thing.

For ever 4 inches, you have 25 miles. Therefore if you have only one, you multiply to find the other. Now, since you have miles, you need to find inches. Therefore, 120 divided by 4, because every 4 inches is equal to 25 miles. Your answer should be 30 inches
