f = (f1 f2) / (f1 + f2)
f(f1 + f2) = f1 f2
f f 1 + f f 2 = f1 f 2
f1 f2 - f f2 = f f1
f2 (f1 - f) = f f1
f2 = (f f1) / (f1 - f) <==== solution
Answer:
The direct consequences of poverty are well-known — limited access to food, water, health care or education are a few examples. However, the consequences of poor living conditions on the community are seldom discussed; indeed, if members of a community suffer from poor living conditions, then the entire community suffers.
Temperature changes depending on the time of the day.
Step-by-step explanation:
Answer:
x: C
y: A
z:
Step-by-step explanation:
In a 45-45-90 triangle, the hypotenuse is larger than either of the legs by a factor of 
. The length of x is therefore:
In a 30-60-90 triangle, the longer leg is larger than the shorter leg by a factor of 
. Therefore:
The hypotenuse of the 30-60-90 triangle is twice larger than the smallest leg, so it has a length of 
.
By the pythagorean theorem, you can find z+y:
Hope this helps!
