{1, 2, 3, … ,97, 98, 99}How many numbers in the set above have 3 as a factor but do not have 6 as a factor?Please ill put brainliest

18. (3,9,15,21,27,33,39,45,51,57,63,69,75,81,87,93,96,99)

Step-by-step explanation:

Please mark me brainliest. I went through every number and calculated if it does or not. It took a while so please.

6 minutes

Step-by-step explanation:

Let the volume of the sink be Xm^3

The rate of filling the sink by the first faucet is R1 while the rate of draining the faucet is -R2(negative since it’s draining)

R1 = x/2

R2 = -x/3 ( negative as it is draining)

The time it would take both of them working at the same rate to fill the sink is as follows:

x/(R1 - R2) = T

x/( x/2 - x/3) = T

x = T(x/2 - x/3)

x = T( (3x - 2x)/6)

x = T(x/6)

x = Tx/6

6x = Tx

T = 6 minutes
