Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24
The answer is 73.24 years.
Answer:
x =
and y = 
Step-by-step explanation:
Known that he sum of angles on a straight line is
. From the diagram;
2y + x + y = 
x + 3y =
................ 1
Also,
2x + x + 2y = 
3x + 2y =
.............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y =
............. 4
7y = 360
y = 
y = 
substitute the value of y in equation 1,
x + 3y = 
x + 3(51.4) = 
x + 154.2 = 
x =
- 154.2
x = 
Thus, x =
and y = 
Answer:
35,-70
Step-by-step explanation:
Answer:
25+1.50m=80
she can travel 36.7 m
Step-by-step explanation:
25+1.5m=80
1.5m=80-25
1.5m=55
m=55/1.5
m=36.6666=36.7
