Answer:
The first step to do is trying to find the closest perfect square less than 845, and the closest perfect square more than 845.
In this case 29^2 (841) is the closest perfect square less than 845, and 30^2 (900) is the closet perfect square more than 845.
In conclusion we will say that 29 < √ 845 < 30.
Hope it helps you.
Answer:
4 4/5
Step-by-step explanation:
Answer:
correct option is D. 630 kcals
Step-by-step explanation:
given data
Ashley weight = 130 lb
exercise time = 48 minutes
VO2 = 2.72 LO2/min
VCO2 = 2.24 LCO2/min
to find out
total energy expenditure
solution
first we get here respiratory exchange ratio that is
respiratory exchange ratio (RER) =
...........1
RER =
RER = 0.823
now we get here calorific value that is
calorific value = 3.815 + 1.23 × RER
calorific value = 3.815 + 1.23 × 0.823
calorific value = 4.827 kcal/L O2
so now we get energy expended that is
energy expended = VO2 × calorific value × time
energy expended = 2.72 × 4.827 × 48
energy expended = 630 kcals
so correct option is D. 630 kcals
