What is the angle between a=7i+3j and b=4i-j

PolarNik [594]

$a\cdot b=(7)(4)+(3)(-1)=25\\\\|a|=\sqrt{7^{2}+3^{2}}=\sqrt{58}\\\\|b|=\sqrt{4^{2}+(-1)^{2}}=\sqrt{17}\\\\\cos \theta=\frac{25}{\sqrt{58}\sqrt{17}}\\\\\theta=\cos^{-1} \left(\frac{25}{\sqrt{58}\sqrt{17}} \right) \approx 37.235^{\circ}$

Isaac made 1 quart and 2 ounces of vegetable dip and poured 3 cups and 3 ounces of it into a bowl. How much dip remains?

defon

If you would like to know how much dip remains, you can calculate this using the following steps:

1 quart = 32 ounces
1 quart and 2 ounces = 32 ounces + 2 ounces = 34 ounces of vegetable dip

1 cup = 8 ounces3 cups = 3 * 8 ounces = 24 ounces
3 cups and 3 ounces = 24 ounces + 3 ounces = 27 ounces poured into a bowl

remaining: 34 ounces - 27 ounces = 7 ounces

The correct result would be 7 ounces.
