The points a b c and d lie on a straight line ab:bd = 1:4
pochemuha

The points a b c and d lie on a straight line ab:bd = 1:4 are A line that extends to infinity on both sides and has no curves is called a straight line.AB:BC=3:4.

<h3>What do you call a straight line?  </h3>

A line is simply an object in geometry denoted as an object with no width that extends on both sides. A straight line is just a line with no curves.

  • AC=AB+BC=3+4=7;  AC:CD=2:1, i.e. AC=2;   because we get 2 different lengths for AC, we change the given ratio AC:CD to an equivalent one with AC=7 .
  • As follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5 )   Now we have AC:CD = 7 : 3.5 and AD = AC+CD= 7+3.5 = 10.5,, and the answer is: the ratio  BC:AD = 4:10.5.

Think about what you have learned about work ethic. In a paragraph of no less than 125 words, explain why employers prefer to hi
Zepler [3.9K]

An individual who possesses good work ethic embodies principles like reliability, dependability, dedication to the job, teamwork and cooperation, and a self-disciplined character. Most employers seek a strong work ethic; performance depends on it; satisfaction is derived from it; and it ensures career progression. It is that untouchable effort an employee exemplifies daily, regardless of whether someone is watching or not. A company that has its employees doing exemplary well has everything to do with their performance. Thus, if you have a strong work ethic, you will have qualities that will keep you in demand by huge companies. When you are skilled at the workplace and your colleagues notice and appreciate it, you will have a very deep sense of satisfaction within you. If you put 101 percent, your willingness to work hard will be recognized and will leave you shining brightly than others when the opportunity of promotion knocks.
