For this case we can make the following rule of three:
1507 ----> 100%
1213 ----> x
Clearing the value of x we have:
x = (1213/1507) * (100)
x = 80.4910418
Rounding off we have:
x = 80.5%
Answer:
this player has made 80.5% of free throws
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12
Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.
The solution to the problem is as follows:
sin(10 deg) = 300/DF
<span>
DF = 300/sin(10 deg) = 1727.63 meters
