Commercial formulas contain 20 calories per 30 ml. a 1-day-old infant was fed 45 ml at 0200, 0530, 0800, 1100, 1400, 1630, 2000, and 2230. what is the total amount of calories the infant received today? record your answer using a whole number.

  240 calories

Step-by-step explanation:

At each feeding, the baby received ...

  45 mL × (20 calories)/(30 mL) = 30 calories

There were 8 feedings, so the total caloric intake was ...

  (30 calories) × 8 = 240 calories

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

the answer is d on edge
