Five minutes after birth, a newborn is pale; has irregular, slow respirations; has a heart rate of 120 beats/min; displays minim
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

Three consecutive integers have a sum of 48 find the integers?
zavuch27 [327]

The sum of three consecutive integers is three times the middle one: if we call the middle one x, the three numbers are

x-1,\ x,\ x+1

So, their sum is x-1+x+x+1 = 3x

Which is three times the middle one.

So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.

So, the three numbers are 15, 16 and 17

Chandra has $36.25 in dimes and quarters If she has 250 coins in total, hwo many
vladimir2022 [97]

Answer:

175 dimes and 75 quarters

Step-by-step explanation:

Make a system of equations, where d is the number of dimes and q is the number of quarters:

d + q = 250

0.1d + 0.25q = 36.25

Solve by elimination by multiplying the top equation by -0.1:

-0.1d - 0.1q = -25

0.1d + 0.25q = 36.25

0.15q = 11.25

q = 75

Then, plug in 75 as q into one of the equations to solve for d:

d + q = 250

d + 75 = 250

d = 175

So, there are 175 dimes and 75 quarters
