Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.
Answer:
19.5
Step-by-step explanation:
The area of a triangle given 3 coordinates can be solved using the formula:

Where
A_x is x coordinate of first point (here 7)
A_y is y coordinate of first point (here 1)
B_x is x coordinate of 2nd point (here 0)
B_y is y coordinate of 2nd point (here 10)
C_x is x coordinate of 3rd point (here 9)
C_y is y coordinate of 3rd point (here 4)
Plugging these into the formula, we get out answer:

Hence, the area is 19.5
all of them???

She would make 7 of her shots shooting or 7/20 percent which is 35% shooting. You can also multiply 20x0.35 and it will give you 7.
