$40.50 10 boxes at 6lbs = 60lbs

             36 boxes at 12 ounces = 432 ounces dived by 16(16 oz in a lbs)= 27 lbs

             60 lbs plus 27 lbs = 87 lbs total weight

 87lbs - 20lbs($12)= 67lbs - 30 lbs($10)= 37lbs x .50($.50 per pound)= $18.50

$12+$10+$18.50= $40.50

The length of line PQ is 7.5 inches. what is the absolute error of the measurement?
Rashid [163]

Answer:

The absolute error of the measurement is 0.25 inches

Step-by-step explanation:

we know that

The absolute error of a measurement is equal to one  half the unit of measure.

In this problem we have

7.5 inches

The measurement is given  by 0.5 inches

So

the absolute error of this  measurement is  

\frac{1}{2}(0.5)=0.25\ in

Therefore

the exact measurement could be between  

7.5 (+/-) 0.25 in

That is, between  7.25 in and  7.75 in
