The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)
<h3>Answers:</h3><h3>Area of parallelogram = 63</h3><h3>Area of triangle = 34</h3><h3>Area of trapezoid = 84</h3><h3>The trapezoid has the largest area</h3>
==================================================
Work Shown:
area of parallelogram = base*height
area of parallelogram = 9*7
area of parallelogram = 63
----------
area of triangle = (1/2)*base*height
area of triangle = (1/2)*10*6.8
area of triangle = 34
----------
area of trapezoid = height*(base1+base2)/2
area of trapezoid = 6*(13+15)/2
area of trapezoid = 6*(28)/2
area of trapezoid = 168/2
area of trapezoid = 84
Answer:
28.26
Step-by-step explanation:
To find the area of a circle you take pi times the radius squared ()
And to find the radius you divide the diameter by two.
For this case we must factor the following expression:
We take the sign "-" as a common factor of the expression, taking into account that:
To factor, we must find two numbers that, when multiplied, result in -48 and when added, result in -2. These numbers are -8 and +6.
Then, we factor the expression within the parenthesis as:
Answer:
