Answer:
308cm²
Step-by-step explanation:
Assuming the given unit is in cm
The expression for the area of a regular Octagon is
A=2(1+√2)a²
Given the apothem a = 8cm
Substituting we have
A=2(1+√2)8²
A= 2(1+1.414)64
A= 2(2.414)64
A= 308cm²
From lea st to greatest it would be 6.200, 6.4, 6.532, and 6.6
Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation
x - y = 280/14
x - y = 20
x = 20 + y
Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10
Substitute this in first equation,
x + 10 = 40
x = 30
In short, Speed of Boat = 30 mph, & speed of current = 10 mph

Answer:
1376 dogs
Step-by-step explanation:
This is just a multiplication problem if we convert the words to mathematical formulas.
There are 86 teams: . Each team has 16 dogs: .
So, we can add up 16 to itself 86 times, which is just 16 * 86 = 1376
Thus, the answer is 1376 dogs.
