Part A: The y-intercept is 5. If you look to the data, when x=0, y=5. This means that the turtle started off 5 miles away from its nest. (at 0 hours, the distance away from his nest was 5 miles)
Part B:Answer=22. Remember, if you take any two distinct points on a line, the slope of the line will be equal to the average rate of change. In short, we're just looking for the slope between the ordered pairs (1,27) and (4,93). The formula for slope is:

The average rate of change between x=1 and x=4 is 22. The average rate of changed describes the rate at which miles is changing with respect the the change in hour.
Part C: Answer=10hours. Since by now we know both the slope and the y-intercept, lets write the equation in slope intercept form and then solve for 225 miles.
y=mx+b
y=22x+5
225=22x+5
subtract 5 from both sides
220=22x
divide both sides by 22
10=x
It would take 10 hours for the turtle to travel 225miles from it's nest.
If x is any given number than I will use the Number five
Your equation will look like this
5^5=25
Diameter = 4 inches
Radius = diameter/2 = 4/2 = 2 inches
Area = πr^2 = π(2)^2 = 4π = 12.57 inches squared approx.
Answer:
x=4
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The answer is B as this is a simple ration question.
All you need to do is convert the question into ration fraction form:
24/60 =x/1990
x is the number of people whose favourite ice-cream is chocolate.
Do cross multiply on both sides and you will get 47760=60x.
x= 796.
Thus, you get your answer.
