Let our two variables be: p # of pharmacy hours b # of babysitting hours Then we should have two statements from the given facts: and We can graph these inequalities by solving for either p or b in both inequality. Once the inequalities are graphed then any point that is shade...
The inequality 10x + 20y > 500 models all of the combinations of scores of 10 and 20 points that will give a total greater than 500 points in a game. What is not true about the values for x and y?
How would you figure: How much energy, in kJ, is absorbed by 23.8 g of acetone when it evaporates if its molar heat of vaporization is 32.0 kJ/mol? Acetone formula is C3H6O
Someone on a glass-bottom boat shines a light through the glass into the water below. A scuba diver beneath that boat sees the light at an angle of 17 degrees with resoect to the normal. If the glass's index of refraction is 1.5 and the water's index of refraction 1.33...
a post is driven into the ground. the first strike drives the post 30 inches into the ground. the next strike drives the post 27 inches into the ground. assume these distances form a geometric sequence, what is the total distance the post is driven into the ground after 8 stri...
