Answer:
The world record for the 200-m dash will be set at 18.0 seconds in the year 2920.
Step-by-step explanation:
To find what year the record will be 18 seconds, substitute 18 in for R, and solve for t.
-0.0028t + 20.8 = R
-0.0028t + 20.8 = 18
-0.0028t = -2.8
t = 1000
The record for the 200-m dash will be 18 seconds after 1000 years. To find which year this record will be set in, add 1000 to the original date, 1920.
1920 + 1000 = 2920

Answer:
24
Step-by-step explanation:
3/8 of the 64 total animals at the zoo are birds.
To solve, this, multiply 3/8 and 64
3/8*64=24
Another way to solve would be to make a proportion
3/8=x/64
Multiply both sides by 64 to get x by itself
64(3/8)=(x/64)64
24=x
So, 24 out of the 64 animals are birds
