Answer:
125˚
Step-by-step explanation:
The angles given are supplementary. So we can set up the equation :
(3x+5)+(x+15)=180
Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.
3(40)+5=<A
120+5=<A
<A=125
Answer:
The approximate population of the small town after 10 years is 6,413
Step-by-step explanation:
Here we note that the general growth formula is given by;

For decreasing rate, we have;

Where:
A = Population after growth
P = Initial population = 13250
r = The annual reduction rate in decimals = 7 % = 7/100 = 0.07
t = Number of years of decrease= 10 years
Since the population is decreasing, then by plugging in our values into the above equation for decreasing rate, we have

= 6.412.766 ≈ 6,413
The approximate population of the small town after 10 years = 6,413
Answer:
Step-by-step explanation:
10+10=20
8+8 = 16
36 is perimeter of the rectangle
diameter of half circle is 8
formula for circumference of a circle is r π = 8 x 3.14
8 x 3.14 = 25.12 but your not done yet its a half circle so divide by 2
25.12/2 = 12.56
12.56 + 36 = 48.56 is final answer
