A rectangle container that has a length of 30 cm,a width of 20 cm,and a height of 24 cm is filled with water to a depth of 15 cm
Ket [755]
<span>V(h 24) = 30 cm*20 cm*24 cm = 14400 cm³ =  14,4 liters</span>
<span>V(h 15) = 30 cm*20 cm*15 cm =    9000 cm³  =  9 liters</span>
<span>                         + 6,5 liters = + 6500 cm³      </span>
9 liters +   6,5 liters = 15,5 liters         =>   15,5 liters -14,4 liters = 1,1 liters
now  15500 cm³   =>    1100 cm³ =1,1 liters  too much !!

A quality control officer is randomly checking the weights of pumpkin seed bags being filled by an automatic
Anni [7]
<h2>Answer:</h2>

Option: D is the correct answer.

   D. x < 397.9 and x > 402.1

<h2>Step-by-step explanation:</h2>

It is given that:

Each bag is advertised as weighing 400 grams.

Also, a  bag must weigh within 2.1 grams in order to be accepted.

Hence, for the bag being accepted the weight must be no less than 2.1 gram from 400 gram and should be no more than 2.1 gram from 400 grams.

i.e. the weight of the bag must be such that:

              400-2.1≤ x ≤ 400+2.1

i.e.

             397.9 ≤ x ≤ 402.1

Hence, if the weight of the bag is less than 397.9 grams or is more than 402.1 grams then the bag will be rejected.

i.e. The range for the bag being rejected is: x<397.9 grams and x>402.1 grams.
