Answer; 47.27 Inches
Let the height of Dagne be x.
Now we are told that she can do a vertical jump that is 27.5% of her height. This is represented as 0.275x.
Now we are told the height she can jump is 13.2. Thus;
0.275x = 13.2
x = 13.2/0.275
x = 47.27 inches
1 hour equals 60 minutes.
Divide the minutes by 60 to find the decimal portion of the time:
21 minutes / 60 = 0.35
Now add that to 3 hours to get decimal hours:
3 hours 21 minutes as a decimal would be 3.35 hours
(x-h)^2+(y-k)^2=r^2
(x-0)^2+(y+2)^2=9^2
x^2+y^2+4+4y=81
x^2+y^2+4y-81+4=0
x^2+y^2+4y-77=0
Put each variable's value in parentheses:
P = 2(2.5) + 2(3 2/5)
Solve and get P = 5 + 6 4/5 which as 11 4/5.
The mixed number answer is 11 4/5
