Answer: 33 gallons
Step-by-step explanation:
We initially have 130 gallons of a acid solution and we need to change it to a
acid solution, and for that it is necessary to evaporate
gallons of water.
So, this situation can be mathemtically expressed as follows:
Then:
Isolating :
Hence, we need to evaporate 33 gallons of water.
Answer:
Polynomial expression that represents the area of blanket:
If :
Step-by-step explanation:
The area of the rectangle can be calculated with the formula:
Being l the lenght of the rectangle and w the width of the rectangle.
In this case, the lenght and the width are represented with:
Substitute them into :
Then:
Use Distributive property (Remember the Product of powers property: ):
Add like terms:
(Simplied form)
Evaluate :
Given:
A synthetic division problem.
To find:
The missing number it in the given synthetic division problem.
Solution:
The given synthetic division problem is:
In synthetic division, we need to add first and second row to get the bottom row.
Similarly,
Therefore, the missing value in the given synthetic problem is 10. Hence, the correct option is C.
