Answer:
The slope is 3 or 3/1.
Step-by-step explanation:
The amount of money will always be counted as a y value. So, you can do 345 - 255, which is 90, over 120 - 90, which is 30. You will have 90/30, that will simplify to 3 or 3/1. Therefore, your slope is 3.
The area of number four, the hexagon, is 841.78.

Answer:
pH = 3.3
Step-by-step explanation:
pH is given by the formula; pH = –log[H+]
The concentration of hydrogen ions is 5.0 × 10–4 moles per liter.
Therefore;
pH = - log₁₀(5.0 × 10^–4)
= -( - 3.301)
= 3.301
Thus;
The approximate pH will be; 3.3
