Let h represent the height of the trapezoid, the perpendicular distance between AB and DC. Then the area of the trapezoid is
Area = (1/2)(AB + DC)·h
We are given a relationship between AB and DC, so we can write
Area = (1/2)(AB + AB/4)·h = (5/8)AB·h
The given dimensions let us determine the area of ∆BCE to be
Area ∆BCE = (1/2)(5 cm)(12 cm) = 30 cm²
The total area of the trapezoid is also the sum of the areas ...
Area = Area ∆BCE + Area ∆ABE + Area ∆DCE
Since AE = 1/3(AD), the perpendicular distance from E to AB will be h/3. The areas of the two smaller triangles can be computed as
Area ∆ABE = (1/2)(AB)·h/3 = (1/6)AB·h
Area ∆DCE = (1/2)(DC)·(2/3)h = (1/2)(AB/4)·(2/3)h = (1/12)AB·h
Putting all of the above into the equation for the total area of the trapezoid, we have
Area = (5/8)AB·h = 30 cm² + (1/6)AB·h + (1/12)AB·h
(5/8 -1/6 -1/12)AB·h = 30 cm²
AB·h = (30 cm²)/(3/8) = 80 cm²
Then the area of the trapezoid is
Area = (5/8)AB·h = (5/8)·80 cm² = 50 cm²
To change a fraction to an equivalent fraction, you can only multiply the numerator and the denominator by the same number (or, multiply the fraction by another fraction equal to 1).
Here you can multiply 2/5 by 2/2 (2/2=1) to get an equivalent fraction.
The answer is D.
We have that
<span>f(x) = 3.45x + 12
substitute for x=2
f(2)=3.45*2+12-------> f(2)=$18.90/month
$18.90 is the amount, that </span><span>Catherine pays for 2 units of power in 1 month
</span>
therefore
the answer is the option
<span>$18.90; this is the amount Catherine pays for 2 units of power in 1 month.</span>
