This kind of triangle is acute triangle because on the given three angles, none of them does not exceed more than 90°.
The speed of the airplane is the ratio of the distance to the time
The initial average speed of the airplane is approximately 110.8 mph
Reason:
Given parameters are;
The distance between Portland Oregon and Seattle Washington = 145 miles
The decrease in travel time when the speed is increase by 20 mph = minutes
The initial speed of the airplane, v = Required;
Solution;
Therefore;
Which gives;
Therefore
0.2·v² + 4·v - 2,900 = 0
v ≈ ±110.8 mph
The initial average speed of the airplane, v≈ ± 110.8 mph

4pockets = 25 multiply by 4 = 100
your answer is 100
Hi! (◕‿◕)
Number of faces: F=a+3
Number of vertices: V=2a
Number of edges: E=4a-1
V+F-E=2
Replacing V=2a; F=a+3; and E=4a-1 in the formula above:
(2a)+(a+3)-(4a-1)=2
Eliminating parentheses:
2a+a+3-4a+1=2
Adding similar terms:
(2+1-4)a+(3+1)=2
(-1)a+4=2
Solving for a. Subtracting 4 both sides of the equation:
(-1)a+4-4=2-4
(-1)a=-2
Dividing both sides by (-1)
(-1)a/(-1)=-2/(-1)
a=2
Answer: The value of a is: a=2
GDP1 = 200*18 = $3600
We assume that the work hours increase to 210 and the productivity falls to 8.
GDP2 - 210*8= $1680
Growth Rate = (GDP2 - GDP1)/GDP1 * 100 = 1000/120000 * 100 = 0.83%
Growth Rate per Capita = (GDP2/p2 - GDP1/p1) / (GDP1/p1) * 100 = -0.17%
The negativity growth rate per capita make some sense, since the population rise to 1% while the GDP only rise by .83%. So that we get a negative number.
So the new zombie's rate of economic growth is equal to -53.33% ((1680 - 3600) /3600) * 100
