Answer:
x=17
Step-by-step explanation:
The angle seen here is 180 degree so the equation we make to solve for the variable should equal to 180
First let's set up our equation:
7x+2x+27=180
Then we will combine like terms:
9x+27=180
Next we have to get rid of 27 so we only have 9x on one side. To do this let's subtract 27 on both sides of the equation:
9x=153
Now all we have to do is divide both sides by 9 to isolate the variable:
and you get x=17
The correct relation for the sea gull population is: P(t) = 5.3t^(11/7)
Answer:
d. about 66.5 hundred thousand
Step-by-step explanation:
Given that :
P(t) = 5.3t^(11/7)
Population, P is in hujdred thousand ; t = number of years
Population after 5 years ;
t = 5
P(5) = 5.3 * 5^(11/7)
P(5) = 5.3 * 5^1.5714285
P(5) = 5.3 * 12.542422
P(5) = 66.474840
P(5) = 66.5 (approximately)
Hence, population after 5 years will be about 66.5 hundred thousand.
Answer:
0.125
Step-by-step explanation:
<u>Smaller Wheel</u>
Total Number of Equal Sectors = 8
The number of Red sectors =3
The probability of obtaining red on the smaller wheel 
<u>Larger Wheel</u>
Total Number of Equal Sectors = 12
The number of Red sectors =4
The probability of obtaining red on the larger wheel 
Assuming that the wheels are independent and each outcome is equally likely, the probability that we get red on both wheels
The probability is: 0.125
The answer is 2[2^2(2-1)]=2*4*1=8
