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.

Help me please and show work

Answer:

Red circle: 30 cm

Blue circle: 60 cm

Step-by-step explanation:

The circle's circumference is calculated with

$d \times \pi$

They want you to make it <em>about</em> how long it is so instead of pi we can just use 3 (since pi is about 3,14). The diameter (d) is double the ratio.

So now we just put in the numbers.

For the red one

$10 \times 3 = 30$

The circumference is about 30 centimetres.

For the blue one

We know the ratio of the smaller so we just add together the small ratio with the rest of the length that we know so the blue one's ratio is 10 cm. (5+5=10)

And now we just put the numbers in again.

$20 \times 3 = 60$

The circumference is about 60 centimetres.

Four different stores posted ads on special 15-oz cans of baked beans -8 for $6 = 75 cents per can -10 for $10 = $1 per can -2 f

worty [1.4K]

Answer:

75 cents per can

Step-by-step explanation:

8 for $6 = 75 cents per can

10 for $10 = $1 per can

2 for $3 = $1.50 per can

The last store sold 28-oz for $1.40 each

To obtain the cost per 15-oz can of baked beans

28-oz / 15-oz = 1.86667of 15 - oz cans of baked beans can be obtained from 28 - oz.

The price per can will now be :

$1.40 / 1.8666666

= $0.75

= 0.75 * 100 = 75 cents

Hence, for the last store, they sold at 75 cents per can similar to the first store.

Choose the point on the terminal side of -210°. Please only answer this question if you are willing to show work so I can learn

N76 [4]

X=rcos∅=r cos (-210)=r cos 210=rcos (180+30)=-r cos 30
$x=-r* \frac{sqrt 3}{2} = \frac{- sqrt 3r}{2} ,$
$y=r sin (-210)=-rsin 210=-rsin (180+30)=-r(-sin 30)$
1 $or y=r sin 30=r* \frac{ 1}{2} = \frac{r}{2}$
