Answer:
The total cost is 1.25 dollars.
Step-by-step explanation:
The reaction between HCl and CaCO₃ is giving by:
2HCl(aq) + CaCO₃(s) → CaCl₂(aq) + CO₂(g) + H₂O(l) (1)
0.500L M: 100.01g/mol
0.400M
According to equation (1), 2 moles of HCl react with 1 mol of CaCO₃, so to neutralize HCl, we need the next amount of CaCO₃:
The CaCO₃ mass of each tablet is:
Hence, the number of tablets that we need to neutralize the HCl is:
Finally, if every 80 tablets costs 4.00 dollars, 25 tablets will cost:
<u>So, the total cost to neutralize the HCl is 1.25 dollars.</u>

Answer:
1. Vertical shrink by a factor of ¹/₅
2. Right 5
3. Up 5
Step-by-step explanation:
Transformations of Graphs (functions) is the process by which a function is moved or resized to produce a variation of the original (parent) function.
<u>Transformations</u>
For a > 0
Identify the transformations that take the parent function to the given function.
<u>Question 1</u>
Comparing the parent function with the given function, we can see that the <u>parent function</u> has been <u>multiplied</u> by ¹/₅.
Therefore, the transformation is:
As 0 < a < 1, the transformation visually is a compression in the y-direction, so we can also say: Vertical shrink by a factor of ¹/₅
<u>Question 2</u>
Comparing the parent function with the given function, we can see that 5 has been <u>subtracted from the x-value</u> of the parent function.
Therefore, the transformation is:
<u>Question 3</u>
Comparing the parent function with the given function, we can see that 5 has been <u>added to the parent function</u>.
Therefore, the transformation is:

D:) infinitely many solutions
D.
Because if you break it down and split the digit place value you can start by doing 3×2000+300+50+4 is going to equal 7062 which is D.
