Answer:
200*(1/2)^n
Step-by-step explanation:
This question can be solved by substituting the value of n= 1,2,3,4 in the both of the expression as there are four terms in the series.
For first expression 100*(1/2)^n-1
Thus formula 200*(1/2)^n correctly expresses the sequence 100, 50, 25,12.5
Answer:
x=16.5
Step-by-step explanation:
12.7 + 3.8 = x - 3.8 + 3.8
16.5 = x
A
reducing one side by 2 is expressed as (x - 2) ← length
increasing the other side by 2 is expressed as (x + 2 ) ← width
the area of new patio = (10 - 2 )(10 + 2) 8 × 12 = 96 ft²
Answer:
According to triangle theorems, we know that the interior angles of a triangle equals 180 degrees. Since we know that angle A and angle B are 55 and 30 degrees, all we need to do is add them up and subtract it from 180 degrees to find out the measure of angle C.
55 + 30 = 85 degrees
180 degrees - 85 degrees = 95 degrees (this is the measure for angle C)
Answer:
-
6 13/18
Step-by-step explanation:
5/9 times -4 is -20 over 9 -20/9 -2 2/9
3/4 times -6 is -18 over 4 -18/4 -4 1/2
You need them to have a common denominator
so you can multiply the first answer by 4 and the second by 9.
You get -242/36 after a while
and then
you simplify.
You can multiply 36 six times into -242 so you get the whole number of 6 plus 216
242-216 is 26
26 over 36 is 13 over 18
-6 13/18
