Answer:
Plants are restrictive to flow of eroding agents, bind soil in their roots.
Step-by-step explanation:
Soil Erosion is the wearing away of the topmost fertile layer of soil. Topsoil gets eroded mainly due to wind, water agents.
Plants help to prevent soil from erosion in following ways :
- Plants act as restriction to the speed of air & water, which are the main soil erosion agents. It also lets rain water get soaked into the ground water.
- Plants roots also bind the soil tightly, & make soil stronger to be eroded by erosive agents - water, air. Eg : Shrubs , trees, grass & ground are important soil erosion preventive plants, because of their extensive root systems.
Answer:
x = 8
Step-by-step explanation:
Given
- 8(- x - 7) = 120 ( divide both sides by - 8 )
- x - 7 = - 15 ( add 7 to both sides )
- x = - 8 ( multiply both sides by - 1 )
x = 8
Answer:
isosceles
Step-by-step explanation:
Answer:
1x + 4y = 4 ⇒ 6x + 24y = 24
6x - 8y = 0 ⇒ 6x - 8y = 0
32y = 24
32 32
y = 3/4
x + 4(3/4) = 4
x + 3 = 4
-3 -3
x = 1
(x, y) = (1, 3/4)

Answer:
The circumference of the circle is: "
37. 7 in." ; or, write as:
"
12
in. " .
______________________________________________________Explanation:______________________________________________________A square has all 4 (four) sides of equal length.
If the perimeter of the square = 48 inches;
the side length of each side of the square = "48 in. ÷ 4 = 12 in." ;
→ "12 in. = the diameter, "d", of the circle within the square" .
The formula for the Circumference, "C" , of a circle, is:
"C =

* d " ;
C =

* d ;
d = 12 in.
C = "
12
in. " ;
or; calculate the Circumference, "C", of the circle; using: "3.14" as an approximation for

;
C =

* d ;
= (3.14) * (12 in.) ;
= 37.68 in. ; round to: "
37. 7 in." .
