Answer 1

Answer:

1.15,072cm

2.117,750

3. 62.8m,31.4m

4-5; One and a half (1 1/2)

Step-by-step explanation:

1.Radius=20cm

C=2x3.14xr

C=2x3.14x20cm

C=125.6cm

How far will it go in 120 turns?

125.6cm×120turns=15,072cm

2.Diameter=50cm

C=2x3.14xr

since the radius is half the diameter;

50÷2=25

C=2x3.14x25=157

How far the diameter travel if it makes 750 revolutions?

157x750=117,750cm

3.Radius=10m

C=2x3.14x10=62.8m

Diameter=10m

since the radius is half the diameter;

10÷2=5m

C=2x3.14x5=31.4m

-The circle with the radius of 10 meter is twice greater than the circle with diameter of 10m

=31.4x2=62.8m

4-5; Diamater=760km

since the radius is half the diameter;

760÷2=380

C=2x3.14x380=2,386.4

-If levi wants to travel for 2000 km around the wall, he may travel one and half. (1 1/2)

Answer 2

Answer:

The bacteria colonize plant cells within root nodules, where they convert atmospheric nitrogen into ammonia using the enzyme nitrogenase and then provide organic nitrogenous compounds such as glutamine or ureides to the plant. The plant, in turn, provides the bacteria with organic compounds made by photosynthesis. This mutually beneficial relationship is true of all of the rhizobia, of which the genus Rhizobium is a typical example. Rhizobium is also capable to solubilize phosphorus.
