1/3x + y = 4....subtract 1/3x from both sides
y = -1/3x + 4 <===
(-2, -9)
Simply plug -2 into the equation.
1.75 or if it’s a fraction 1 3/4
Step-by-step explanation:
The delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles
<h3>What is population density?</h3>
Population density can be defined as the number of individuals within a species in a specific geographic area.
The formula for population density is expressed as;
Population density = Number of people/Land area
Where;
- Number of people = 20000
- Population density = 1000
Land area = 20000/ 1000
Land area = 20 square miles
But ;
Area = πr²
Substitute the value of area in the formula
20 = 3. 142 × r²
r² = 20/ 3. 142
r² = 6. 37
r = √6. 37
r = 2. 5 miles
Thus, the delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles
