Answer:

Step-by-step explanation:
I assume that the three points given are the vertices of the triangle. So the three points are:
A (-4,1)
B (-7,5)
C (0,1)
The area of a triangle is given by:

where b is the base and h is the height.
Here we can take as follows:
- We can take the base to be the side AC, so that its length is equal to the distance between the two points:

- The height of the triangle is therefore the perpendicular distance between AC and point B. This is equivalent the difference in the x-coordinate between any point on AC and B, so:

Therefore, the area of the triangle is:

Answer:
Step-by-step explanation:
note : P(C or D) = P(C)+P(D) - P(C and )
P(C or D) =0.29+0.47- 0
P(C or D) = 0.76
Answer:
1. MIGHT be 16 1/2
Step-by-step explanation:
causse 2/3 / 4/9 = 1 1/2
1 1/2 + 10= 11 +5 = 16
16+1/2 = 16 1/2
Answer:
64
Step-by-step explanation:
If you measure the cubes inside for the length, width and height, you get:
Length - 5 cubes
Width -5 cubes
Height - 3 cubes
The volume of the prism is 5 * 5 * 3 = 75. This means the prism can hold a total of 75 cubes
The amount of cubes already in there is 11
so 75 - 11= 64
