there are 148 juniors and 272 seniors attending prom this year. if there must be three chaperones per 60 students, how many chap
valkas [14]

21 chaperones are needed for 420 students.

Step-by-step explanation:

No. of juniors = 148

No. of seniors = 272

Total = 148+272 = 420 students

3 chaperones = 60 students

1 chaperone = \frac{60}{3}=20\ students

Ratio of chaperon to students = 1:20

Let,

x be the number of chaperons for 420 students.

Ration of chaperones to students = x:420

Using proportion

Ratio of chaperones to students :: Ratio of chaperons to students

1:20::x:420

Product of mean = Product of extreme

20*x=420*1\\20x=420\\

Dividing both sides by 20

\frac{20x}{20}=\frac{420}{20}\\x=21

21 chaperones are needed for 420 students.

What’s the answer to this problem , figure out the area and perimeter of this triangle
Zigmanuir [339]

Answer:

                Area = 67.5 m²

        Perimeter = 69 m

Step-by-step explanation:

<h3>Area of triangle:</h3>

   b = 27 m  & h = 5 m

     \sf \boxed{\text{\bf Area of triangle =$\dfrac{1}{2}bh$}}

                                   \sf = \dfrac{1}{2}*27*5\\\\     =\dfrac{135}{2}\\\\= 67.5 \ m^2

<h3>Perimeter of triangle:</h3>

       Perimeter = sum of all sides

                         = 27 + 34 + 8

                         = 69 m
