If it is a square then find the square root of 400. Which would get you 20. So 20 is the length of one side since it is a square you multiply 20 by 4 to get 80. The perimeter is 80 feet
Answer:
1400 sq. ft
Step-by-step explanation:
60 min = 1 hour
280 sq. ft / 12 min = x / 60 min
x = 60 min * (280 sq. ft / 12 min)
minuets cancel out
x = 1400 sq. ft
Answer:
The appropriate solution is:
(1) 22.81 minutes
(2) 0.171

For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
option 4
$ 3.75 + $ 2.49=$6.24
$6.24 / 2= $ 3.12
Each will pay $3.12
