The factory used to produce 126 articles a day. As a result of retooling, production increased to 189 articles a day. What was t
NARA [144]

Answer: The answer is 50%.


Step-by-step explanation:  Given that the factory produces 126 articles in a day. After retooling, the production of the articles increased and they started producing 189 articles in a day. We need to calculate the percent increase in labour productivity.

We have,

Percent Increase in labour productivity will be equal to the percent increase in the number of articles.

Increase in the number of articles after retooling = 189 - 126 = 63.

Therefore, percent increase in the number of articles is given by

p=\dfrac{63}{126}\times 100\%=\dfrac{100}{2}\%=50\%.

Thus, the labour productivity increased by 50%.

sladkih [1.3K]

Answer:

45

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

2x - 12 + 2x + 17 + 9x - 7 = 180 add like terms

13x - 2 = 180 add 2 to both sides

13x = 182 divide both side by 13

x = 14

m<X = 2x + 17 replace x with 14

2*14 + 17 = 45
