Please help! 9/4(7+3-4*9)
Serga [27]

Answer:

58.5

Step-by-step explanation:

This expression should be simplified using order of operations. According to order of operations or PEMDAS, complete any numbers in parenthesis then any exponents, multiplication, division, additions and subtraction moving left to right through each operation.

Begin with Parenthesis.

(7+3-4*9) - Multiply first

(7+3-36) - Then add/subtract left to right

10 - 36 = -26

Replace -26 where the parenthesis were in the original expression.

9/4 (-26)

SpyIntel [72]
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))

The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)

S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi

After 30 days, he will have traveled 82.25 miles.
