a quantity of carbon - 14 will take 1342.5 years to become 1/8 of its original size.
Step-by-step explanation:
1/2 of the atoms decayed after 5370 years
now half of( 1/2 of )the atoms decayed after 5370/ 2 years
i.e, 1/4 of the atoms decayed after 2685 years.
again half of (1/4 of the atoms ) decayed after 2685/2 years
i.e, 1/8 of the atoms decayed after 1342.5 y<u>ears.</u>
Answer:
<em>m = 1 </em>
Step-by-step explanation:
Slope =
-4 - 1 = -5
3 - (-2) = 5
5/5 = 1
Slope is 1

Answer:
55.8292 cm
Step-by-step explanation:
Circumference is diameter x pi.
7 x 3.14 = 21.98 inches
21.98 x 2.54 = 55.8292 cm
Answer:
The answer to your question is 10 children and 4 adults
Step-by-step explanation:
Data
Adult cost = a = $11
Children cost = c= $7.50
Total people = 14
Total cost = $119
Number of adults and children = ?
Process
1.- Write two equations to solve this problem
a + c = 14 ----------- l
11a + 7.5c = 119 ----------- ll
2.- Solve the equations by elimination
Multiply equation I by -11
- 11 a - 11c = -154
11a + 7.5c = 119
0 -3.5c = -35
c = -35/-3.5
c = 10
3.- Find a
a + 10 = 14
a = 14 - 10
a = 4
4.- Conclusion
The group bought 4 tickets for adults and 10 tickets for children.
Answer:
well 0
Step-by-step explanation:
basically when a point lies on an axis,one of its coordinates must be zero,let's say point a-
if you look at how far the point is from the origin along the x-axis,the answer is zero,therefore the x-coordinate is zero,any point that lies on the y-axis has an x-coordinate of zero.
