Step-by-step explanation:
first you go by counting by 2s and when your done it says one will ride alone so minus 1 that is 5 so the answer will be 5
From the half life equation, the remaining fraction 
where t = total time elapsed and T = Half life
Now, it is given that, 
And remaining fraction is
So, substituting these values in the above equation,
Taking log both sides,
Solving, we obtain that,
years
Answer:
The slope is 4
Step-by-step explanation:
First we pick 2 points (x, y):
(0, -2) and (1, 2)
Then, we use the slope (m) formula:
m = (y2 - y1)/(x2 - x1)
Given:
y2 = 2
y1 = -2
x2 = 1
x1 = 0
Work:
m = (y2 - y1)/(x2 - x1)
m = (2 + 2)/(1 - 0)
m = 4/1
m = 4
Answer:
G = 110
Step-by-step explanation:
The figure is a quadrilateral, which means the sum of the angles is 360
We know that angle E and G are the same
100+40 + E + G =360
Combine like terms
140 +E+G = 360
Replace E with G since we are looking for G
140 + G + G = 360
140 +2G = 360
Subtract 140 from each side
140-140+2G=360-140
2G = 220
Divide by 2
2G/2 =220/2
G = 110
