Question:

Linda bought 3 notebooks at \$1.20 each; a box of pencils at \$1.50 and a box of pens at \$1.70. How much did Linda spend?

You must first figure out how much Linda spent on notebooks. Since 1 notebook = \$1.20 Then 3 notebooks = 1.20 x 3 = \$3.60 Linda spent a total of (\$1.5 + \$1.7) on pens and pencils Total amount spent = 3.60 + 1.50 + 1.70 = \$6.80

Question:

A 600 mL sample of nitrogen is heated from 27 °C to 77 °C at constant pressure. What is the final volume?

The first step to solving gas law problems should be converting all temperatures to absolute temperatures. In other words, if the temperature is given in Celsius or Fahrenheit, convert it to Kelvin. This is the most common place mistakes are made in this type of homework problem. T K = 273 + °C Ti = initial temperature = 27 °C Ti K = 273 + 27 Ti K = 300 K Tf = final temperature = 77 °C Tf K = 273 + 77 Tf K = 350 K The next step is to use Charles' law to find the final volume. Charles' law is expressed as: Vi/Ti = Vf/Tf where Vi and Ti is the initial volume and temperature Vf and Tf is the final volume and temperature Solve the equation for Vf: Vf = ViTf/Ti Enter the known values and solve for Vf. Vf = (600 mL)(350 K)/(300 K) Vf = 700 mL Answer: The final volume after heating will be 700 mL.

Question:

Given that F(x) = 3x + 2 Find F(3) + F(5) - F(4)

This questions pertains to functions. The key to functions is to remember that any element that exists in the domain of a function MUST have an output , or in this case a range. F (x) = 3x + 2 Simply plug the elements in... F(3) = 3 *(3) + 2 = 11 F(5) = 3* (5) + 2 = 17 F(4) = 3* (4) + 2 = 14 Now place them altogether.... 11 + 17 - 14 = 28 - 14 = 14. This is your final answer
