Let K=average weight of an okapi and L=that of a llama.
3L=K+190 and K+L=450 so K=450-L. Therefore 3L=450-L+190, 4L=640, L=160kg and K=450-160=290kg.
Okapi weighs 290kg, llama weighs 160kg.
You can tell a fraction is a unit fraction if it has a one above it examples 1/2 1/3 1/4
Let log2 (1/64) = x. Then,
2^x = 1/64
2^x = 1/(2^6)
2^x = 2^(-6)
So,
x = -6
log2 (1/64) = -6 <----- this is the answer.
I hope this helps. =)
Hello! our answer here is going to be:
43.
Lets understand this a little better!
when dealing with exponents, it is the base number (3) times its self how ever many the above number is (3 again)
so, it wont be 3 x 3, but instead 3 x 3 x 3 because that's how much the exponent is.
same rule applies with 4^2!
