Answer:
44 degrees
Step-by-step explanation:
Since MN is a tangent, it forms a right angle wheng it intersects line MP since MP is the diameter. So, 90+46 is 136 and since there are 180 degrees in a traingle, 180-136 is 44.

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:
n = 5
Step-by-step explanation:
Given
5n + 20n = 5(n + 20), that is
25n = 5(n + 20) ← divide both sides by 5
5n = n + 20 ( subtract n from both sides )
4n = 20 ( divide both sides by 4 )
n = 5
