Answer:
A. 1/5
Step-by-step explanation:
To find scale factor, simply find the length of one side on the copy and divide by the length of the corresponding side on the original.
For instance, the top side of the copy is 1 unit long, and the top side of the original is 5 units long. So, take 1 divided by 5 to get a scale factor of 1/5.
Answer:
C. about 25 years.
Step-by-step explanation:
We have been given that two Jackie takes off on a round-trip to Vega, 25 light-years away. She travels at an average speed close to the speed of light, say, 0.9999c.
To find time it will take Jakie to reach Vega, we will divide the distance of Vega by Gwen's speed.
![\text{Time}=\frac{\text{Distance}}{\text{Speed}}](https://tex.z-dn.net/?f=%5Ctext%7BTime%7D%3D%5Cfrac%7B%5Ctext%7BDistance%7D%7D%7B%5Ctext%7BSpeed%7D%7D)
![\text{Time}=\frac{25}{0.9999}](https://tex.z-dn.net/?f=%5Ctext%7BTime%7D%3D%5Cfrac%7B25%7D%7B0.9999%7D)
Therefore, it will take approximately 25 years for Jakie to reach Vega and option C is the correct choice.
Answer:
<em>Yes, the sum of a multiple of 3 and a multiple of 3 is closed under addition.</em>
Step-by-step explanation:
Let S = { 3n | n ∈ Z } be the set of multiples of 3.
So if x and y are two multiples of 3, then we can write that
x = 3n and y = 3m for some integers n and m in the set of integers i.e. Z.
To determine that the sum of 3n and 3m is closed under addition. As
x + y = 3n + 3m = 3(n + m) ∴ from the distributive property
As we can check that n + m is also an integer, as n + m ∈ Z
Also, x + y = 3 (n + m) is a multiple of 3.
<em>Therefor, the sum of a multiple of 3 and a multiple of 3 is closed under addition. </em>

Answer:
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
- first you divide both sides by 2 pi, which cancels out the other 2 pi
- then you square both sides, which cancels out the square root
- lastly you multiply both sides by g, which leaves you with L
to simplify:
- square the things in the brackets
- and multiply by g over 1, which is the same as g
- and as according to the pronumeral rule, you arrange the letters in alphabetical order
