Answer:
2520cm²
Step-by-step explanation:
Surface area = sum of the area of all the bases.
Area of bottom base = 28 * 30 = 840
Area of right base = 25 * 30 = 750
Area of left base = 17 * 30 = 510
Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420
Then add all the areas together to find surface area
Surface area = 840 + 750 + 510 + 420 = 2520cm²
Relevant Formulas:
Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base
Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles.
0.191= 19.1%
338mL × 0.191= 64.558mL acid
We round to the nearest tenth, getting a total of 64.6mL acid.
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
