Peter's salary is twice anne's salary and half of david's salary. then the average salary of anne and david is _ of peter's salary

Average of salary of Anne and David is 1.25 of Peter's Salary

In the question, relations between salaries of Peter, Anne, and David is given. From the given relations, we need to make few equations and calculate the average of Anne and David in terms of Peter's Salary.

Let us assume Peter's Salary as P.

Then we can calculate Anne's salary A = .

Also David's salary = D =

Average of Anne's and David's salary =

Average of Anne's and David's salary  =

Average of Anne's and David's salary  =

Average = 1.25 \times P

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
