well, in short, the students and chaperones are at a 2 : 9 ratio, and we know there are 171 students, how many chaperones then, so long they maintain a 2:9 ratio?

\bf \cfrac{chaperones}{students}\qquad 2:9\qquad \cfrac{2}{9}\qquad \qquad \cfrac{x}{171}=\cfrac{2}{9}\implies 9x=2(171) \\\\\\ 9x=342\implies x=\cfrac{342}{9}\implies x=38

WILL MARK YOU BRAINLIEST. Please help
olya-2409 [2.1K]

Answer:

20%

Step-by-step explanation:

Well, it's actually relatively simple.

The first thing to do would be to write this in a fraction form. You payed 72,000 out of 360,000.

72,000/360,000.

now you take that fraction, and convert it's to its decimal form which will give you a 0.2.

0.2 in decimal form is converted to 20.0% (when you convert a decimal to a fraction, you multiply by 100, or move the decimal two places to the right).

Another way to do this is simplifying the fraction.

take 72,000/360,000 and find what X is when

72,000/360,000 = x/100

you will find that 72,000/360,000 Is equal to 20/100. since percents are calculated as out of a hundred. your answer would still come out as 20%

Select the correct answer. Which equation represents a line that is perpendicular to line FG?
emmasim [6.3K]

Answer:

Hey there!

Equation of Line FG: y=\frac{1}{2} x+3.5, because the slope (rise over run) is 2 and we see that the y intercept is 3.5.

Equation to a Line Perpendicular to FG: y=-2x-3\\, because the equations of perpendicular lines have the same (but could also be different y-intercepts), and opposite reciprocal slopes.

Let me know if this helps :)
