She has 90 markers because 18 times 5 is 90
- Midpoint Formula:
Plug the coordinates into the midpoint formula and solve as such:
<u>Your midpoint is (5,-1).</u>
Answer: W is your answer :)
Step-by-step explanation:
Answer: Choice C) 10.5
The distance from A to C is 7 units (count out the spaces between the two points, or subtract y coordinates 4-(-3) = 4+3 = 7)
Let AC = 7 be the base of the triangle. You might want to rotate the image so that AC is laying horizontally rather than being vertical.
Now move to point P. Walk 3 spaces to the right until you land on segment AC. This shows that the height of the triangle is 3 when the base is AC = 7.
base = 7, height = 3
area of triangle = (1/2)*base*height
area of triangle = 0.5*7*3
area of triangle = 10.5 square units
0.67, because when you have a percent like that you just need to move the decimal 2 places to the left.
