Answer:
1/4
Step-by-step explanation:
The equation for the area of a triangle: A = 1/2bh
If all of the dimensions are halved then A = 1/2(1/2*b)(1/2*h) = 1/8bh
1/8bh is 1/4 of 1/2bh.
Answer:
=1050 wildebeests
Step-by-step explanation:
We can form an arithmetic series for the wildebeest migration.
Sₙ=n/2(2a+(n-1)d) where n is the number of terms, d is the common difference and a is the first term.
a=24
n=20
d=3
Sₙ=(20/2)(2(24)+(20-1)3)
Sₙ=10(48+57)
=1050 wildebeests
This is my answer. I can to screenshot it as it would not let me post.
