Answer:
hours of work done by assistant = 17.85
hours of work done by plumber = 35.7
Explanation:
Given data:
charges of plumber is $30
charges of assitant is $15
total labor charge is $1875
let x is the total hour of job by assistant
and 2x is total hours of job by plumber
so we have
15x + 30\times 2x = 1875
15x + 90x = 1875
105x = 1875
x = 17.85
therefore plumber work 2x i.e 35.7
hours of work done by assistant = 17.85
hours of work done by plumber = 35.7

Hi
Some tips for training for a marathon, for example could be running approximately 5 kilometers, to reach the end of a half marathon you need a more advanced physical and mental capacity that will only be achieved with constant training. To be prepared and endure it is necessary dedication and constant work for at least 5 weeks. We could start with a short series of training, for example distances not greater than 400 meters, this will help to influence the technique, also the strength. If we dedicate this type of training one day a week, we improve the speed and pace of the race. Another type of training is the background. This type of training aims to run a greater distance or more time than in the rest of your workouts of the week. It is not necessary that they be over the distance of competition but they do approach that one and its frequency must be weekly or every 6 days of training.
The only energy-rich connection that our muscle can have immediate form for a contraction is a substance called ATP, whose decomposition into ADP and phosphorus generates the energy needed to perform the movement. Since we do not have many molecules of this ATP in muscle, it is necessary to continuously generate this element to get the necessary chemical energy and therefore the subsequent mechanical energy. The ways to obtain this energy in training is through two ways: aerobic and anaerobic. In the first one there is a sufficient amount of oxygen for the oxidation of glycogen and fatty acids. In anaerobic oxygen supply is insufficient for oxidation, due to a high load intensity, and therefore the energy is obtained anaerobically, that is, without the presence of oxygen.

Explanation:
The chemical composition of salt is made by an acid and a base, in general it doesn't cause any good reaction in our bodies, just adds taste to the food but no more, and basically for its chemical composition it could increade the blood preasure level, other important fact is, during the salt's process extraction, this is mixed with other chemicals to make it lighter and whiter, and at the end all this chemicals flow into our blood system, acidifying our body and increasing blood preasure.
