30 years - 14 years = 16 years
82 coins - 18 coins = 64 coins
64/16 = 4 coins per year or 4 countries per year
Shirley should visit about 4 countries per year.
Answer:
Step-by-step explanation:
1) 
Altitude = 2
Period = 2pi/(1/2) = 4pi
(since 1/2 is coefficient of x)
Altitude interval = [-4,0]
Domain interval = set of all real numbers
Phase shift = 0
Vertical shift = 2 down
2) y=-4sin(2x+pi/2)-2
Altitude = 4
Period = 2pi/(2) = pi
(since 2 is coefficient of x)
Altitude interval = [-6,2]
Domain interval = set of all real numbers
Phase shift = pi/2
Vertical shift = 2 down
11% = 0.11
6.5% =0.065
0.26 = 26%
-0.195 = -19.5%
-111 = -11100%
Answer:
1 1/3
Step-by-step explanation:
Half of 2 is 1, Half of 2/3 is 1/3. Thus, 1+1/3= 1 1/3
Answer:
x = 20
y = 28
Step-by-step explanation:
hari's age: x
harry's age: y
7x = 5y
4(x+4) = 3(y+4)
4x+16 = 3y+12
4x+4 = 3y
5/3(4x+4) = 5y = 7x
20/3x +20/3 = 7x
20/3 = 1/3x
x = 20
y = 28
