Betsy and Marie both got their haircut on the same day bed she gets her haircut every 28 days and Mary gets her haircut every 35 days how many days will it be until they both get their haircut on the same day again

140 days until they both get their haircut on the same day again

Step-by-step explanation:

When two events, A and B, happen every x and y days, respectively, they will happen on the same day in each lcm(x,y) days. lcm(x,y) is the lesser common multiple of x and y which is not 0.

In this question:

Betsy every 28 days.

Mary every 35 days.

Multiples of 28: {0,28,56,84,112,140,...}

Multiples of 35: {0,35,70,105,140,...}

So the lesser common multiple between 28 and 35 is 140.

So

140 days until they both get their haircut on the same day again

last graph i believe

step-by-step explanation:

worked it out i believe

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
