Answer:
A. 2CO + O2 ---> 2CO2
Step-by-step explanation:
2CO + O2 ---> 2CO2
This can be solved algebraically. Before we start, as context, to find a percentage you multiply by the percentage/100.

This tells us that 90 is
120% of 75. However, your question wants us to find the <em>increase</em>, therefore we don't need that 100.
Therefore, the increase is
20%.
Answer:
Simplify by combining like terms
Step-by-step explanation:
She transforms
1/2 - 2x + 1 = -13/2
into
3/2 - 2x = -13/2
combining the terms 1/2 and +1 to get 3/2. Combining like terms is a very common step while solving an equation which allows us to simplify the expressions and is generally made before isolating the variable step.
First we need to find the heigh of the soda can be rearanging the volume formula, . We can make that We know that V is 36 and radius is half of the diameter, so radius is 2.
h = 2.87
Now, we can use the height to figure out the volume of a cone. The volume of a cone is
R is 2 again and h is 2.87
12.56*.96 = 12.0576
So a cone with a volume of 12.0576 is the largest that will fit into the soda can
