Since it is in the thousandths place, the value of the six is .006
hope this helps :)
7 centimeters is a possible length for the third side ⇒ B
Step-by-step explanation:
Let us revise the triangle Inequality Theorem
- The sum of the lengths of any 2 sides of a triangle must be greater than the length of the third side
- To prove that by easy way add the smallest two sides, if their sum greater than the third side,then the sides can form a triangle
Assume that the length of the third side is x cm
∵ The length of two sides are 7 cm and 10 cm
∵ The length of the third side is x cm
- Put the sum of x and 7 greater than 10 ( x and 7 are the smallest sides)
∴ x + 7 > 10
- Subtract 7 from both sides
∴ x > 3
- Put the sum of 7 and 10 greater than x (7 and 10 are the smallest sides)
∵ 7 + 10 > x
∴ 17 > x
∴ x < 17
- By using one inequality for x (combined the two inequalities in one)
∴ 3 < x < 17
That means the length of the third side is any number between 3 and 17
There is only one answer between 3 and 17
∵ 7 is between 3 and 17
∴ The length of the third side could be 7 cm
7 centimeters is a possible length for the third side

Answer:
64
Step-by-step explanation:
Lets take mei lin's first four test scores to be 60 since it average out to be 60.
After the 5th test,
mei lin new average score is
![\frac{new \: total \: score}{total \: number \: of \: tests} \\ = \frac{60 + 60 + 60 + 60 + 80}{5} \\ = \frac{320}{5} \\ = 64](https://tex.z-dn.net/?f=%20%5Cfrac%7Bnew%20%5C%3A%20total%20%5C%3A%20score%7D%7Btotal%20%5C%3A%20number%20%5C%3A%20of%20%5C%3A%20tests%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B60%20%2B%2060%20%2B%2060%20%2B%2060%20%2B%2080%7D%7B5%7D%20%5C%5C%20%20%3D%20%20%5Cfrac%7B320%7D%7B5%7D%20%20%20%5C%5C%20%20%3D%2064)
A Relation is said to be a Function if an element of Domain of the Function has one and only one image in the Co-domain of the Function.
⇒ A is not a Function, Because Element 4 has Three images
⇒ B is a Function, Because Each Element has a Unique Image
⇒ C is not a Function, Because Element 7 has Two images
⇒ D is a Function, Because Each Element has a Unique Image
⇒ E is a Function, Because Each Element has a Unique Image
So, The Relations which are Functions are : B - D - E
