Decimal calculations (division) and unit conversion. a packaging company can fill a 3-pound box in 0.4 seconds and move to the next box in 0.1 seconds. how many 2-pound boxes can be filled by the machine in 3 hours?

29454

Step-by-step explanation:

Given in the question,

3 pound box  0.4 sec

1 pound box   0.4/3

                            2/15 sec

2 pound box 2*2/15

                            4/15 sec

One 2 pound box can be filled and move to next box in 4/15 + 0.1

= 11/30 sec

We know that 1 hour = 3600 seconds

                     3 x 3600 = 10800 seconds

2-pound boxes can be filled by the machine in 3 hours

10800/ 11/30

29454 boxes

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
