By rename do you mean turn into an improper fraction?
if so, it is because without turning it into an improper fraction, you cannot subtract 3/4 from 1/4 because you would get a negative answer and that would be incorrect
Answer:
the process by which oxygen released into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis.
Explanation:
Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings
Answer:
Eritrea has faced several challenges since gaining independence from Ethiopia in 1993. The country has only one political party that maintains all of the control. Democratic national elections have yet to be held; the transitional government is still in power, and no constitution has been implemented. Furthermore, territorial disputes with Ethiopia continue. Eritrea's command economy is struggling. Over 80% of the population is engaged in subsistence agriculture. Climate changes have created problems for agriculture, and drought is a major issue. Finally, property damages due to war have proven costly.
Explanation:
That is the correct sample response.
There is a strong link between increased levels of education for females and lower fertility rates. That is, the higher the level of a woman's educational attainment, the fewer number of children she is likely to bear, and this effect is shown in countries and cultures around the world.
The volume of the cone is calculated by the formula:
V = B*H/3
r=D/2 = 6/3 = 2
where B is surface area of basis and H is height.
B is circle which fomula for surface is:
B = r^2 * pi = 3^2*3,14 = 9*3,14 = 28.26
from condition of height we write:
H = 3*D = 3*6 = 18
now volume is:
If we express all of that in equation of volume we get:
V = 1/3* 3^2*3,14*18
