Answer:a
Step-by-step explanation:did it
You need to set this up with a proportion and solve. 18/x-5 = 13.5/12.
cross multiply 13.5x-67.5=216
now solve for x
13.5x=283.5
x=21
the missing side is equal to 21-5, which is equal to16
Answer:
Equation: P = P0(1.04)^n
Population at 12 years: 4323
Step-by-step explanation:
The population starts at 2700 and increases by 4% per year. In equation form this can be written as:
P = P0(1.04)^n
Where P is the final population, P0 is the initial population, and n is the number of years.
Subbing in 2700 for P0 and 12 for n we get:
P = 2700(1.04)^12
P = 4323
Answer: 1/4 chance of picking red
Step-by-step explanation: There are 120 buttons in all, so the fraction of red marbles is 30/120. 30/120 = 1/4
