The answer is $46.22, you do $42.80 plus 8% on a calculator
117 and 413 have no common denominator, so 117/413 is it's simplest form
Answer:

Step-by-step explanation:
Since you are multiplying the same thing by itself, it'll have an exponential value, so count the t's and that is your exponent. Don't forget the "-" sign.
Answer:
The answer is A!!
Step-by-step explanation:
The right triangle with angle 45 ° has adjacent leg 9 feet
So the opposite leg is calculated from
tan 45 = opposite leg / adjacent leg ⇒ adjacent leg = 9 tan 45 = 9.
That is the distance bc.
The right triangle with angle 60° has adjacent leg 9 and opposite leg (x+9), where x is the distance ab.
Then tan(60) = (x+9) / 9 ⇒x+9 = 9 tan(60)
x + 9 = 15.59
x = 15.59 - 9 = 6.59
Answer: 6.59 feet
