Answer:
Mary's mistake was that she didn't take into account of the power that 10 is raised to; since 2.01 is multiplied by 10 to the 6, it makes 2.01 bigger. You can also expand the number to check:
2 010 000 vs. 4800
Simplify the expression and you get 3a^4B
Just substitute the value x into the equation y=2x
y = 2x
y = 2(-1)
y = -2
use the same method for the rest
The number of 0.4 liter glasses of water that will be poured in the pitcher is 13
From the information given, we are being told that a pitcher can hold a maximum amount of 5.2 liters of water.
If we are to use a 0.4 liter of glass to pour water in the pitcher, then the number of times we will use the glass to pour water in the pitcher can be estimated as:
Number of glass that can fill the pitcher = 5.2 liters/ 0.4 liters
= 13 glass
