To evaluate the given expression, we must follow the rules of PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) in solving.
Therefore, first calculate what's inside the parentheses:
(1619.2) / (8194.23)
Then perform the operation in between the parentheses:
<span>(1619.2) / (8194.23) = 0.20
</span>
Therefore the answer after evaluating the expression is 0.20.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
500 meters/4 minutes = 125 meters/minute
<span>4 minutes / 500 meters = 0.008 minutes/meter</span>

Answer:
6825
Step-by-step explanation:
From the equation, the series is a geometric series, such that
a = 5
r = 4
n = 6
sum of a geometric series is a(r^n - 1)/(r - 1)
therefore,
sum of the series is 5 x (4^6 - 1) / (4 - 1)
= 5 x (4096 - 1) / 3
= 5 x 4095 / 3
= 6825
Plug in -6 for a and -5 for b
3(-6)^2 - 4(-5)
3(36)+20
108+20
=120
