Question

find fourth proportional to 6,8,10*​

Answer 1

Answer:

SOLUTION

TO DETERMINE

The fourth proportional of 6 , 8 , 10

EVALUATION

Let x be the fourth proportion

Then 6 , 8 , 10 , x are in proportion

So

\displaystyle \sf{ 6: 8 = 10 : x}6:8=10:x

\implies \displaystyle \sf{ \frac{6}{8} = \frac{10}{x} }⟹

8

6

=

x

10

\implies \displaystyle \sf{ 6x = 80}⟹6x=80

\implies \displaystyle \sf{ x = \frac{80}{6} }⟹x=

6

80

\implies \displaystyle \sf{ x = \frac{40}{3} }⟹x=

3

40

FINAL ANSWER

The fourth proportional of 6, 8, 10 is

\displaystyle \sf{ = \frac{40}{3} }=

40

Answer 2

Answer:

Nitrogen Fixation -Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrogen Assimilation -This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. FIXATION

Ammonification -Thisis part of the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back intoammonium so it can re- enter the nitrogen cycle. Nitrification- This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can thenabsorb. Denitrification -Extra nitrogen in the soil gets put back out into the air. There are special bacteria that perform this task as well.
