A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
mote1985 [20]

Answer:

36

Step-by-step explanation:

We need to find the LCM of the two numbers because we need to know the lowest number that 12 and 9 are both in.

12 × 1 = 12

12 × 2 = 24

12 × 3 = 36

12 × 4 = 48

9 × 1 = 9

9 × 2 = 18

9 × 3 = 27

9 × 4 = 36

We can see that 36 is the lowest number that occurs both in 12 and 9 so the blue and red light will both link at 36 seconds

Natalija [7]

Answer:

5

Step-by-step explanation:

The Apgar score is calculated based on 5 medical criteria:  

-Appearance – skin color

-Pulse – heart rate (taken with a stethoscope or by feeling the umbilical cord)

-Grimace – reflex response

-Activity – muscle tone

-Respiration – breathing quality

Each one of the criteria is evaluated on a 0 to 2 scale, once every criteria are measured, the values are added up and the child would have an Apgar score between 0 and 10.  

Here:

Apparence = 0

Pulse = 2

Grimace = 1

Activity = 1

Respiration = 1

Total= 2 + 1 + 1 + 1 = 5
