Answer:
18 weeks
Step-by-step explanation:
We are given the (time, population) pairs (0, 5) and (7, 47). With these values, we can use the two-point form of the equation of a line to write the equation of the linear model.
p = (p2 -p1)/(t2 -t1)(t -t1) +p1
p = (47 -5)/(7 -0)(t -0) +5
p = 6t +5 . . . . . the linear model matching the given points.
For p = 113, the time (number of weeks) is ...
113 = 6t +5
108 = 6t . . . . . . subtract 5
18 = t . . . . . . . . . divide by 6
After 18 weeks, the beetle population will reach 113.
Ok so direct variation is y=xk
invers is y=k/x
it seems to be that x is on top
therefor
y=x times 1/3
y=xk
direct variation
Answer:
44 cubic meters
Step-by-step explanation
9 + 4 + 6 = 19
9/19 of the patio will be cement
4/19 of the patio will be gravel
6/19 of the patio will be stones
Work out the amount of gravel - 4/19 * 209 = 44 cubic meters
