I believe it is a rational number
Answer: Our required expression is
Step-by-step explanation:
Since we have given that
Cost of game system = $219
Cost of sports pack = $115
Now, we need to calculate the total amount he spent in dollars is given by
This is our required expression which equals the amount he spent in dollars.
Now, the total cost he spent will be
Hence,our required expression is
The wording of the questions seems tricky but it’s actually simple
What it means is the total sum is 11 of 2 numbers
And the difference is 5
So fine the other number:
11-5= 6
6 is the other number
Answer:
first one
Step-by-step explanation:
1. What is the true density of water?
The true density of water is 1 g/cm³. (Actually, the exact density if water is not really 1 g/cm³, but a bit less (very, very little less), at 0.9998395 g/mol at 40 degree Celsius)
2. What variables change the density of water?
Temperature and purity can change the density of water.
3. How does water go against the concept of "Thermal Expansion"?
When water is a liquid, the water molecules are packed relatively close together but can slide past each other and move around freely(as stated earlier, that makes it a liquid). As the temperature increases or decreases from 4 degree Celsius, the density of water decreases.
