Answer:
Surface Irrigation. Water is scattered equally throughout the land with the help of gravitational pull and it doesn’t require a machine to take care of it.
Localized Irrigation. Water is scattered throughout the land under low pressure.
Drip Irrigation. In this process of drip irrigation, the water drops fall on the root of every plant that is around the system.

Answer:
2.5
Explanation:
The given costs for the purchase and delivery of the cupcakes are;
The cost of 10 cupcakes and the delivery fee = $30
The cost of 25 cupcakes and the delivery fee = $67.50
Let 'c' represent the fixed cost of delivery of the cup cakes, and let 'x' represent the cost of each cup cake, we have;
30 = 10·x + c...(1)
67.50 = 25·x + c...(2)
Subtracting equation (1) from equation (2) gives;
67.50 - 30 = 37.50 = 25·x - 10·x + c - c = 15·x
∴ x = 37.50/15 = 2.5
The cost of each cupcake, x = 2.5
(∴ The delivery fee = 30 - 10 × 2.5 = 5)
The cost of each cupcake is 2.5.
Answer:
true
Explanation:
as temperature decreases, medium particles move slower. so it would take longer for energy to transfer into sound waves.
