Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
The total population in the region is 942000
<u>Step-by-step explanation:</u>
Radius of the region= 10 miles
Population density= 1500 per square mile
Area of the region = 2π(r x r)
= 2π(10 x 10)
=2(3.14) (100)
= 628 square miles
Population = 1500 x 628
= 942000
The total population in the region is 942000
X^2 + 6x - 27
(x - 3)(x + 9)
The answer is: (x - 3)(x + 9).
I think it’s 3.2 but I don’t know
Double is double, so you can solve
.. 2 = 1*e^(.08t)
and get the correct value of t.
Taking logs,
.. ln(2) = .08t
.. ln(2)/.08 = t ≈ 8.7 . . . . years
