The ratio of the second to the third reagent is 3:5.
If 3 parts correspond to 30 mL, then 1 part = 30 / 3 = <<30/3=10>>10 mL.
Thus, 5 parts = 5 × 10 = <<5*10=50>>50 mL of the third reagent.
A paleobotanist examines fossilized leaves and finds that the ratio of broadleaf to needle-like plants in a prehistoric forest was 7:4. If she identifies 84 broadleaf fossils, how many needle-like fossils would her data suggest?
The ratio 7:4 means 7 parts broadleaf to 4 parts needle-like.
If 7 parts = 84 fossils, then 1 part = 84 / 7 = <<84/7=12>>12 fossils.
So, 4 parts = 4 × 12 = <<4*12=48>>48 needle-like fossils.
A computational analyst displays public health data showing that the number of weekly flu cases increased linearly from 120 in week 1 to 300 in week 6. What is the predicted number of cases in week 10 if the trend continues?
The increase over 5 weeks is 300 − 120 = 180 cases.
So, the weekly increase is 180 / 5 = <<180/5=36>>36 cases per week.
