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:

a(n)=1.15[a(n-1)]

Step-by-step explanation:

we know that

$115\%=115/100=1.15$

Let

a0 -----> the length of the original copy

The first copy is equal to

a1=1.15(a0)

The second copy is

a2=1.15[1.15(a0)] or a2=1.15[a1]

The third copy is

a3=1.15{1.15[1.15(a0)]} or a3=1.15[a2]

therefore

A recursive formula will be

a(n)=1.15[a(n-1)]

A private ship carries two types of cargo: large crates and extra-large crates. Each type of crate weighs a specific amount.

Arisa [49]

Answer:

G. 32

Step-by-step explanation:

32 x 335 = 10720

16,100 - 10720 = 5380/190 = 28.3157894737

275 x 32 = 8800

18,800 - 8800 = 10,000/400 = 25 (This is the closer).

30 x 335 = 10,050

16,100 - 10,050 = 6050/190 = 31.8421052632

30 x 275 = 8250

18,800 - 8250 = 10550/400 = 26.375 (Same reason why it does't work)

25 x 335 = 8375

16,100 - 8375 = 7725/190 = 40.6578947368

25 x 275 = 6875

18,800 - 6875 = 11925/400 = 29.8125

24 x 335 = 8040

16,100 - 8040 = 8060/190 = 42.4210526316

24 x 275 = 6600

18,800 - 6600 = 12200/400 = 30.5

AlekseyPX

Answer:

The original price of the item is $28.

Step-by-step explanation:

So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.

So:

First convert 25% to a decimal, 0.25.

OP(original price) = 21 ÷ 1 - 0.25 =

1 - 0.25 = 0.75

21 ÷ 0.75 = 28.

3.2-4d=2.3d+3 i need the answer

borishaifa [10]

Answer:

d=0.031746

Step-by-step explanation:

1. Add 4d to both sides: 3.2=2.3d+3+4d

2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3

3. Subtract 3 from both sides: 3.2-3=6.3d

4. Simplify 3.2-3 to 0.2: 0.2-6.3d

5. Divide both sides by 6.3: 0.2/6.3=d

6. Simplify 0.2/6.3 to 0.031746: 0.031746=d

7. Switch sides: d=0.031746

Hope this helped!
