Question

What does inversely proportional mean?

Answer 1

Inversely Proportional: when one value decreases at the same rate that the other increases.

Answer 2

examples?

Answer 3

i don't think s i can explain but
i know the equation for inverse prp \[\huge\rm y=\frac{ k }{ x }\]haha :P

Answer 4

What is the K?

Answer 5

K is constant

Answer 6

^what she said :)
constant of variation

Answer 7

In this equation, we know that if y increases, x decreases and vice versa

Answer 8

The time it takes to erect a bonfire is inversely proportional to the number of students doing the work. If it takes 20 students 1.5 hours to do the job, how long will it take 35 students to do the job, to the nearest minute?

Answer 9

time = y
students= x

Answer 10

THis is a super confusing problem

Answer 11

okay equation for inverse variation is y =k/x <--(y inversely proportional to x)
read the question
**time it takes to erect a bonfire is inversely proportional to the number of students**
time inversely proportional to number of students
let time = t
students = S
so equation would be \[\huge\rm t =\frac{ k }{ s }\]

Answer 12

when t =1.5 s=20 so plug in t and s value solve for k (constant of variation)

Answer 13

ohhhh okay so 30

Answer 14

that's k
you need y value when =35
so now use the same equation solve for y

Answer 15

\[\rm y=\frac{ 30 }{ 35 }\]

Answer 16

6/7

Answer 17

6/7 x 60 = 360/7 = 51.43 minutes

Answer 18

***to the nearest minute*** so 60 sec in a mint multiply that by 60

Answer 19

so 51 minutes?

Answer 20

ye

Answer 21

got it thanks!!
