Nastasia [14]

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

Triangle OPQ is similar to triangle RST. Find the measure of side RS. Round your answer to the nearest tenth if necessary. OPQR
Andrews [41]

Answer:

RS  =  75.3

Step-by-step explanation:

You need to set up the proportion of corresponding sides.

\frac{PQ}{ST}  =  \frac{PO}{RS}

\frac{7}{31}  = \frac{17}{RS}

7(RS) = 31(17)

         =  527

RS = 527/7 = 75.2857...

     =  75.3
