A.)
original/ new-original = x/100
118,000/138000-118,000= x/100
118000/20000= x/100
118/20=x/100
20x=11800
11800/20=590
The population increased 590%
ANSWER= 25
a= 4 b=7
10+(7-4)•5
subtract 7-4= 3
10+3•5
multiply 3•5=15
10+15
add them and your answer is 25
Step-by-step explanation:
The area of a circle = pi r^2
d = 2r Divide by 2 to get the radius
r = d/2
The diameter = 2.8 cm
r = d/2
r = 2.8/2
r = 1.4
The area of the circle = pi * r^1
The area of the circle = 3.14 * 1.4^2
The area of the circle = 6.1544
But you are working with a semic circle
The area of a semicircle is 1/2 that of a circle
Area of semicircle = 1/2 6.1544 = 3.0772 =3.08 when rounded
