Consider the problem: Andre poured 27 ounces of rice into 6 containers. If all containers have the same amount of rice, how many ounces are in each container? Select an equation to represent the situation. A "?" is used to represent the unknown quantity.
a.6 x ? = 27
b.27 ÷ = ?
c.27 x 6 = ?
d.6 ÷ 17 = ?

4.5 ounces

Step-by-step explanation:

if you divide the amount of ounces (27) by the number of each container (6) you can find how many ounces are in each container. [27÷6=4.5]

oxygen became plentiful on earth

Explanation:

This is because banded iron formation is formed as a result of oxygen present in the ocean which is produced from cyanobacteria which undergo photosynthesis to produce carbohydrates and oxygen.

The oxygen produced are plentiful and they react with dissolved iron on the Earth's ocean to produce iron oxides which precipitated out and form a thin line floor on the ocean.
