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
The sum of three consecutive integers is three times the middle one: if we call the middle one 
, the three numbers are
So, their sum is 
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
Answer:
7x+14=0, 7x=-14, x= -2
Step-by-step explanation:
add like terms, then get x on one side, number on the other, then divide both sides by 7
Answer:
Step-by-step explanation:
π/2 < 4π/5 < π
4π/5 is in Quadrant II
sin(4π/5) = y-coordinate of A
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
