Answer:
let the original price be 100%
then,100%-38%=62%
if 38% decrease =$27.28
let,62%decrease=x
by cross multiplying and dividing
x=$44.51 decrease
the sum of the %decrease=100%
also$44.51+$27.28=original price=$71.79
Answer:
264 ft²
Step-by-step explanation:
The right triangle shown at the right end of the figure has a missing leg that can be found using the Pythagorean theorem. (If you recognize the triangle as a 5-12-13 triangle, you already know its length is 12 ft.)
a² +b² = c²
5² + b² = 13²
b² = 169 -25 = 144
b = √144 = 12
So, the height of the parallelogram is 12 ft, and its base length is 22 ft. The area is the product of these ...
A = bh = (22 ft)(12 ft) = 264 ft²
