Answer:
Step-by-step explanation:
y = 3 fruit trees
x = 7 nut trees
Constant of proportionality = k
k = y/x
k = 3/7
f = 3/7n
Only answer if yk it! correct answer gets brainliest!

Answer:
The cost of leveling the ground is Rs 5340.6
Step-by-step explanation:
Given:
Diameter of the road roller = 90 cm
Length of the road roller = 2m 10 cm
Total number of number of revolution = 400
Cost of leveling = Rs 2.25 per square meter
To Find:
Total cost of leveling the ground = ?
Solution:
Step 1 : Finding the surface area of the road roller
Converting cm to m
90 cm = 0.9 m
2m 10 cm = 2 + 0.1 m = 2.1 m
Surface area of the road roller = surface are of the cylinder
=
r= radius of the road roller
r=
r=0.45
Now surface area is
=>
=>
=>
=>5.934
Step 2 : Finding the area of the ground
Total area of the ground = Surface area of the road roller X number of revolutions
=>
=> 2373.6
Step 3 : Finding the cost of leveling
Total cost of leveling = area of the ground X Cost per square meter
=>
=>5340.6
