Simple,
2.) If a circle is divided into 9 parts and your are trying to find three of those parts, first find what is 1 of those parts...
In a circle there is 360°
360/9=40
That is 1 part.
For three parts it would be 40*3=120
Your answer is 120°
3.) Do the same thing here.
A circle is 360°
360/10=36
Now, for four of those parts...
36*4=144
The answer is 144°.
First factor the second fraction's denominator.
It is a difference of squares so it can be factored as (y + 4)(y - 4)
Notice the first fraction's denominator is y + 4. So you already have that.
Therefore the LCD is (y + 4)(y - 4) :)
Answer:

Step-by-step explanation:
Answer:
No solution because the lines are parallel and never intersect. If it were two perpendicular lines the solution would be where the two lines intersect.
Step-by-step explanation:
It takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
<em><u>Solution:</u></em>
Given that:
principal = $ 25000
rate of interest = 5 %
Total amount = $ 30000
Number of years = ?
Formula used:
Total amount = principal + Simple interest
30000 = 25000 + Simple interest
Simple interest = 30000 - 25000
Simple Interest = $ 5000
<em><u>The simple interest is given as:</u></em>
![S.I = \frac{pnr}{100}](https://tex.z-dn.net/?f=S.I%20%3D%20%5Cfrac%7Bpnr%7D%7B100%7D)
Where, "p" is the principal
"n" is the number of years
"r" is the rate of interest
Substituting the values in formula, we get
![5000 = \frac{25000 \times n \times 5}{100}\\\\5000 = 250 \times n \times 5\\\\n = \frac{5000}{250 \times 5}\\\\n = 4](https://tex.z-dn.net/?f=5000%20%3D%20%5Cfrac%7B25000%20%5Ctimes%20n%20%5Ctimes%205%7D%7B100%7D%5C%5C%5C%5C5000%20%3D%20250%20%5Ctimes%20n%20%5Ctimes%205%5C%5C%5C%5Cn%20%3D%20%5Cfrac%7B5000%7D%7B250%20%5Ctimes%205%7D%5C%5C%5C%5Cn%20%3D%204)
Thus it takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
