7
Step-by-step explanation:
Answer:
12km/h
Step-by-step explana:
Let's call the total distance 2a from which we can calculate t1 equivalent to the first half of the distance a/10 similar to t2 is a/15 from which the total time is a/6 . We have the average speed equal to the total distance dduowcngf divided by the total inferred time by 2a/(a/6) which equals 12km/h
Answer:
y = (1/2)x + 3
Step-by-step explanation:
The points are separated by 1 vertical unit for each 2 horizontal units, so the slope of the line through them is ...
slope = vertical change / horizontal change = 1/2
There is a point on the y-axis at y=3 where x=0, so we know the y-intercept of the line is 3. Then, in slope-intercept form, the equation of the line can be written ...
y = slope · x + y-intercept
y = (1/2)x + 3
Answer:
(a)(b)=0.45
a/b=0.8
Step-by-step explanation:
a=0.6
b=0.75
(a)(b)=(0.6)(0.75)=0.45
a/b=0.6/0.75=0.8
