Answer:
Y=1/3
Step-by-step explanation:
X=k/y
So let's make k the subject of formula
k=xy
x=1,y=5
So let's substitute
k=1×5
k=5
So we are to determine the value for y when x is 15
So let's solve
Y=k/x
Y=5/15
Y=1/3
Y=0.333333~0.3
So..... 14 + 3= 17. I think. I mean, this is what I got from what I understand.

Step-by-step explanation:
Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have
so
the slope is 
therefore
The constant of proportionality k is 
Answer:
0.04%
Step-by-step explanation:
If there are 1000 penguins per square miles, <em>the total number of penguins in a 10 square miles will be 1000*10 = 10,000 penguins/10square miles</em>
Since a polar bear has a territory of 10 square miles, and<em> can only eat four penguins within the 10square miles;</em>
<em />
Percentage of penguins that the polar bear can eat will be expressed as;
number of penguin eaten per 10square miles/total number of penguin per 10square miles * 100
Percentage of penguins that the polar bear can eat = 4/10,000 * 100%
Percentage of penguins that the polar bear can eat = 4/100%
<em>Hence, the percentage of penguins that the polar bear can eat in the 10 square miles is 0.04%</em>
