Answer: Top right graph
Less/more than is a filled in dot.
Less/more than or equal to is an unfilled dot.
a) 57.10 mi/ps b) (57.10,1),(114.20,2), and (171.30,3);
A) The constant rate of change in mi/ps is 57.10, since that is what is being added every time.
B) The coordinate points for the graph (time=x,distance=y) would be (57.10,1),(114.20,2), and (171.30,3). the x is horizontal distance, the y is vertical distance.
Step-by-step explanation:
Multiply the amount of feet in one mile by the amount of miles in the question(5,280 x 50 = 264,000)
Divide the amount of feet in 50 miles by the amount of minutes in 1 hour to get the amount of feet per mile (264,000 ÷ 60 = 4,400)
Divide the amount of feet per mile to get by the amount of seconds in a minute to get the amount of feet per second (4,400 ÷ 60 = 73.33)
Your answer rounded to the nearest whole number is 73
Answer:
70
Step-by-step explanation:
In this problem, 27 adults conduct a survey.
In the results of the survey, it is found that 35% of the adults are concerned with poverty.
If we call:
x = number of adults surveyed
y = adults concerned with poverty
This means that we can write the following relationship:
(1)
where 
represents the percentage of adults concerned with poverty, rewritten in decimal form (
)
Later, we are told that 200 adults are surveyed, so now we have
x = 200
So substituting into eq(1) we can find how many of these adults are concerned with poverty:
