It was reported that about 80% of airline tickets-nearly $65 billion worth last year are issued over the internet. What were the
frozen [14]

Answer:

The answer is nearly $81 billion.

Step-by-step explanation:

  • If we know that 80% of airline tickets worth $65 billion, then 65=80\%\plus{Total_{tickets}}=0.8\plus{Total_{tickets}}\\.
  • Then,to know how much billion dollars worth the total tickets, we just have to clear out Total_{tickets} of the equation, by dividing both sides by 0.8, which yields \frac{65}{0.8}=Total_{tickets}=81.25

Which relationship describes angles 1 and 2?
MissTica
<span>1) supplementary angles => sum of angles' measure is 180°


Two lines intersecting creating four angles with the left obtuse angle labeled one and the acute angle to the right labeled two

= > angle 1 +  angle 2 = 180°

Then those two match.


2) complementary angles => sum of the two angles = 90°

Two lines intersecting in a right angle with a square indicating a right angle in quadrant one and a ray splitting quadrant two with a two labeling the left angle and one labeling the angle on the right

=> angle 2 + angle 1 = 90°

Then those two match

3) vertical angles

Two parallel horizontal lines intersected by a vertical line with a square indicating a right angle in quadrant one of the top line and a one labeling the angle in quadrant two and two labeling quadrant four of the top line

Those two matches because the angle label 1 and the angle label 2 are vertical angles as per the definittion.

4) adjacent angles

Two lines intersecting in a V shape with the left angle of one hundred fifty seven degrees and a bottom angle of X degrees

Those two match becasue the angle of 157° and the angle of X° are adjacent.

Including a 6% sales tax, an inn charges $155.82 per night. Find the inn's nightly cost before tax is added.
Feliz [49]

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x
