Complete question:
In 2016, the city of Rio de Janeiro had a population density of 5377 people/km2.
What was the population density of Rio in people per square meter?
Answer:
0.005377 peope/m²
Step-by-step explanation:
Given that :
Population density of Rio in 2016 = 5377 people/km²
To obtain population density in people per square meter, we convert 5377people/km² to people per m²
Recall:
1000 m = 1km
Hence,
5377 people/km² = 5377 people / (1000²)m
= (5377/1000000)people/m²
= 0.005377 peope/m²
Answer:
11/16
Step-by-step explanation:
First get common denominators
1/4*4/4=4/16
15/16-4/16=11/16
11/16 is the answer
Answer
B
Step-by-step explanation:
5*5*6=150
Y= 2x-1
Explanation: First, you find slope. If the first point it x-axis point is 0 and the second x-axis point is 1 then you already know the answer is over 1, so you have to figure out how many up you are going on the y-axis from -1 to 1. Which is 2, so your slope is 2/1 or just 2. Next, you find your y-intercept, which is where the line crosses the y-axis, and the easy way to find this is finding what y is equal to when x is equal to 0, in the problem you are told (0, -1) as a point, so they gave you your y-intercept right there, which is -1. Finally you right the equation in slip intercept form (y= mx+b) which is y= 2x-1
