- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?

Answers

Answer:

Mariana takes the two pills together after 18 hours.

Step-by-step explanation:

Mariana must take two pills; one every 6 hours and another every 9 hours.

She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.

To find the time to take the two pills together, take the least common multiple of 6 and 9.

6 = 2 x 3

9 = 3 x 3

So, the least common multiple is 2 x 3 x 3 = 18

So, she takes the two pills together after 18 hours.

Sheldon has a traditional health insurance plan. He has a $200 deductible. The level of co-insurance for his plan is 90/10, where 10 represents Sheldon’s portion. He does not have a co-payment. If Sheldon incurs a $1,500 hospital bill, how much money will the insurance company pay for the bill?

Answers

The answer is $1,170. The hospital bill is $1,500 less the $200 deductible which is $1,300. Sheldon will then pay for 10% of his portion so multiply $1,300 by 10% with is $130 and deduct it to $1,300 which gives you $1,170.

AB and BA name the same ray.
Always
Never
Sometimes

Answers

Answer:

AB in terms of rays, can never be BA.

Step-by-step explanation:

AB and BA name the same ray.

No, this is never true. A ray starts from a point and move in a single direction to infinity.

So, if starting point is A and ray is moving towards B, so it will continue moving towards the points further from B.

Therefore, AB as in terms of rays, can never be BA.

They are never the same ray. ray AB begins at point A and goes through point B to infinity and ray BA begins at point B and goes through point B to infinity
