To multiply fracti0ons, we need to convert them to improper fractions:
-2 1/4 = -9/4
-4 1/2 = -9/2
Now, lets multiply:
-9/4 * -9/2 = 81/8
Hope this helps!
Take note that the answer is positive because when multiplying, two negatives make a positive.
Answer:
A) $29.68
B) $5.60
Step-by-step explanation:
<u>Part A Explanation)</u>
To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>
<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>
28.00 + (28.00 * .06) = 29.68
<u>Part B Explanation)</u>
This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.
28.00 * .20 = 5.6
<em>.20 out of 1 is 20%</em>

Answer: (2,0)</h3>
Explanation:
The vector (0,2) points directly north and the length of this vector is 2 units. It's the distance from (0,0) to (0,2).
When rotating 270 degrees counterclockwise, we'll turn to the left or westward direction (90 degrees so far) then at some point aim directly south (180 degrees so far) and finally ultimately end up pointing directly east (after getting to 270). So that's how we go from (0,2) to (2,0).
If you were to go clockwise, then everything flips and you'll ultimately end up pointing directly west. The length of the vector stays the same the whole time.
Well not all lines are lines of symmerty, because if you draw a let's say a rectangle on a piece of paper and draw a diagonal line through it, well the two sides don't really lie perfectly on one another!!
