natima [27]

The correct answer is option A, that is, a landfill in the region of nonporous bedrock.  

A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.

A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.

Illusion [34]

The correct answer is A. 20.2 s

Explanation:

The table shows there were three trials to measure how much time a toy car needs to move 1 meter on different surfaces. Now, to find the average time on a surface simply add the results of the three trials and divide this by number 3 (number of trials). The process to know the average time on dirt is shown below:

20 + 19.2 + 21.5 = 60.7 - Results of each of the trials

60.7 ÷ 3 = 20.2 s - Divide the total by the number of trials

This means the average time for the toy to move on dirt was 20.2s
