Answer:
Number of term N = 9
Value of Sum = 0.186
Step-by-step explanation:
From the given information:
Number of term N = 
Number of term N = 
Number of term N = 9
The Value of the sum can be determined by using the expression for geometric series:

here;
m = 5
n = 9
r = 0.5
Then:




Answer:
The length of the ribbons in all were 25.3 meters.
Step-by-step explanation:
Given:
Lengths of the three pieces of ribbon were 10 meters and 9 decimeters, 3 meters and 10 decimeters, and finally 10 meters and 4 decimeters.
Now, to find the length of the ribbons in all.
So, by adding the length of all three pieces we get the length of all the ribbons:



.
Now, converting the decimeters into meters = 23 meters + 2.3 meters = 25.3 meters.
(1 decimeter = 0.10 meter)
(23 decimeter = 2.3 meter.)
Therefore, the length of the ribbons in all were 25.3 metres.

Here we go ~
Slope of the graph can be expressed as :





So, the value of x is 24 units
Answer:
y = -1/4x + 4
Step-by-step explanation:
(8,2) and (-4, 5)
Slope = (5 - 2)/(-4 - 8)
= 3/-12 = -1/4
Point (8,2)
b = 2 - (- 1/4)(8)
b 2+ 2 = 4
