Answer:
60 meters
Step-by-step explanation:
The area of Square B is the difference of the areas of squares C and A, so is 225 square meters. The side length is √225 = 15 meters, so the sum of the lengths of the four sides is 4·15 = 60 meters.
The perimeter of square B is 60 meters.
Answer:
45.3 grams will be left
Step-by-step explanation:
Use the formula
A = P(1 - r)^t where A is the final amount, P is the initial amount, r is the percent change as a decimal, and t is the amount of time
Plug in what we know, we are given P = 780, r = 0.163, and t = 16
A = 780(1 - 0.163)^16
Now simplify...
A = 780(0.837)^16
A = 45.25868493
A = 45.3
