Answer:
11 months
Step-by-step explanation:
185 - 20 = 165
165 ÷ 15 = 11
Answer:
B. 4 3/8
Step-by-step explanation:
7/8 X 5 = 4 3/8
Given:
Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.
To find:
The area of the remaining tin.
Solution:
Area of a square is:
![Area=a^2](https://tex.z-dn.net/?f=Area%3Da%5E2)
Where, a is the edge of the square.
Area of the smaller square is:
![A_1=(3.7)^2](https://tex.z-dn.net/?f=A_1%3D%283.7%29%5E2)
![A_1=13.69](https://tex.z-dn.net/?f=A_1%3D13.69)
Area of the larger square is:
![A_2=(6.3)^2](https://tex.z-dn.net/?f=A_2%3D%286.3%29%5E2)
![A_2=39.69](https://tex.z-dn.net/?f=A_2%3D39.69)
The area of the remaining tin is:
![A=A_2-A_1](https://tex.z-dn.net/?f=A%3DA_2-A_1)
![A=39.69-13.69](https://tex.z-dn.net/?f=A%3D39.69-13.69)
![A=26](https://tex.z-dn.net/?f=A%3D26)
Therefore, the area of the remaining tin is 26 sq. cm.
You should take into account that the radius is half the diameter and the diameter is the length from the side to side of a circle.
To understand this question, we need some knowledge on radioactive decay. This type of nuclear decay is called a beta decay
<h3>Beta Decay</h3>
This is the process where a radioactive material is fired or naturally emits a beta particle which is equivalent to the lose of an electron and spontaneously becomes an entirely different element.
![^6_2He \to ^6_3 Li + ^0_-_1e](https://tex.z-dn.net/?f=%5E6_2He%20%5Cto%20%5E6_3%20Li%20%2B%20%5E0_-_1e)
The participating actors in this nuclear reaction are
This is the decay process of helium particle in which it became a lithium particle and emitted an electron in the process.
