Answer:
Perimeter of figure = 68 centimeter
Step-by-step explanation:
Given information:
Width of side = 12 centimeter
Length of side = 22 centimeter
Find:
Perimeter of figure
Computation:
Perimeter of rectangle = 2[l + b]
Perimeter of figure = 2[Width of side + Length of side ]
Perimeter of figure = 2[12 + 22]
Perimeter of figure = 2[34]
Perimeter of figure = 68 centimeter
Answer:
1.5
Step-by-step explanation:
Answer:
The population increased by 34.69% over 20 years.
Step-by-step explanation:
It is given that the population of dolphins increases at a constant rate of 1.5% every year for 20 years.
Formula for population increase:

where, a is initial population, r is growth rate and t is time in years.
If the population of dolphins increases at a constant rate of 1.5% every year for 20 years, then the population after 20 years is



Where, a is the initial population.
The total percentage increase over the 20 years is

where, P is population after 20 years and a is initial amount.





Therefore the population increased by 34.69% over 20 years.
Answer:
6. 300/4 feet per hour or feet/hour
7. 90/10 feet per second or feet/sec
Try simplifying the fractions though.
Step-by-step explanation:
average rate of change just means the change in distance per the change in time (per meaning divided by). what is the change in distance? 700-400 = 300. change in time is 6-2 = 4 hours. so 300/4
Same thing, change in distance is 100 - 10 feet and change in time is 40-30 seconds so the average rate of change is 90/10 feet per second
Y=2/3x+2/3
I hope this helps!
