Let n be the amount of time it takes for them to shampoo the carpet together. Then:
1/3+1/6=1/n
2n+n=6
3n=6
n=2 hours to shampoo the carpet together

Answer:
Step-by-step explanation:
cot(x)=cos(x)/sin(x)
sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)
(sin^2 + cos^(x))/sin(x) = 1 / f(x)
1 / sin(x) = 1 / f(x)
Taking the reciprocal of both sides, we get
sin(x) = f(x)
Answer:
F = 6
Step-by-step explanation:
When something is inversely proportional to another thing, when one of the numbers increases or gets multiplied by a constant, the other number decreases or gets divided by a constant.
In this scenario, when F = 3, d = 4.
When d = 2, we are dividing the earlier value of 4 by 2. Now, since F is inversely proportional to d, we have to multiply the value of F by 2 to get what F equals when d = 2. 3 times 2 is 6, so F = 6 when d = 2.
Second, fourth and fifth.
2^4 = 2*2*2*2 =16
4^2= 4*4 =16
16^1= 16=16
