M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)
M=103
So martha has 103 coins!
A. Sigma notation
The formula for finding the nth value of the geometric series
is given as:
an = a1 * r^n
Where,
an = nth value of the series
<span>a1 = 1st value in the geometric series = 940</span>
r = common ratio = 1/5
n = nth order
The sigma notation for the sum of this infinite geometric
series is therefore,
(see attached photo)
B. Sum of the infinite geometric series
The formula for calculating the sum of an infinite
geometric series is given as:
<span>S = a1 / (1 – r)</span>
Substituting the given values:
S = 940 / (1 – 1/5)
<span>S = 1,175</span>

A pentagon needs 540 degrees in total to be a complete pentagon.
-----------------------------------------------
Solution:
Add all angles.
121 + 108 + 102 + 100 = 431
Subtract to 540.
540 - 431 = 109 degrees.
-----------------------------------------------
Answer:
x = 109 degrees
-----------------------------------------------
Hope This Helped! Good Luck!
X= total acres on farm
x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres
ANSWER: There are a total of 800 acres on the farm

"t", is the time the first car has travelled when reaching "d" distance,
whatever that is, at that point, the second car is passing it
