Washington high school's head tennis coach, Ms. racket, runs a tennis camp for middle school students every summer. the students bring their own lunches, but Ms. racket provides them with snacks. there is a proportional relationship between the number of students who enroll in Ms. racket's tennis camp, x, and the total number of snacks she buys, y. what is the constant of proportionality? write your answer as a whole number or decimal. snacks per student.
X Y
10 30
13 39
14 42
21 63
The constant of proportionality is 3 as for 1 student she buys 3 snacks.
The constant of proportionality means the ratio between the terms x and y.
It is calculated by dividing y by x.
Here we get that:
X Y constant of proportionality(Y/X)
10 30 3
13 39 3
14 42 3
21 63 3
Therefore, we get the constant of proportionality as 3.

I think it’s 90% cuz it’s 45/50 therefore 90/100
184 x 7 = 1288
7 x 6 = 42
so you have 42 <span>defective bulbs</span>
Given:
The scale of a map is 
.
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,
It means, 80 miles in real life = 
on the map.
1 mile in real life = 
on the map.
60 mile in real life = 
on the map.
= 
on the map.
= 
on the map.
Therefore, the buildings are apart on the map.
