Answer:
- 1205 people per square miles
Step-by-step explanation:
- Population = 10 511 215
- Area = 8 723 square miles
<u>Population density is the number of people per unit of area:</u>
- 10511215 / 8 723 = 1205 people per square miles
(a)
A right angle sums to 90
6x + 4x + 10 = 90
10 x = 80
x = 8
(b) straight line = 180
5x + 13 + 3x + 7 = 180
x = 20
(c) Sum of triangle angles = 180
3x + 5 + 2x + 18 + 2x + 17 = 180
x = 20
(d) Sum of two angles in right angle = 90
90 = x + 30
x = 60
Answer:
v = -8
Step-by-step explanation:
2 + v/2 = -2
Subtract 2 from each side
2-2 + v/2 = -2-2
v/2 =-4
Multiply each side by 2
v/2*2 = -4*2
v = -8
Answer:
This is false because any number divided by 0 is undefined.
