Answer:
Step-by-step explanation:
We are given the vertices of triangle ABC. We need to find the length of median AD.
Please see the attachment for figure.
D is mid point of BC because median bisect the opposite side of triangle.
Using the formula of mid point. we get coodrinate of D
D is mid point of B(1,5) and C(-3,-1)
AD is median of triangle ABC. Now we find length of median AD using distance formula of two coordinate.
A(5,1) and D(-1,2)
Thus,
i don’t know your choices but this is the answer i got: -2(9x-10)
Answer:
1. 0.05x90
2. 4.5
Step-by-step explanation:
1. 0.05(50+40)
50+40=90
0.05x90
2. 0.05(50)+0.05(40)
0.05x50= 2.5
0.05x40= 2
2.5+2= 4.5
That all i could do sorry but I hope this helps
Answer:
0.4
Step-by-step explanation:
Radius of inner circle = r
Radius of entire circle = r + r + r + r + r = 5r
Probability that an arrow hitting the target will land on inner circle ;
Area of inner circle / area of entire circle
Recall :
Area of circle = πr²
Hence ;
πr² / π(5r)² = πr² / π25r² = 1 / 25 = 0.4
