Existen tres órdenes de producción en proceso. Las ordenes A y B juntas tienen 150 unidades; B y C juntas, 100 unidades, y A y C juntas, 150 unidades. ¿Cuánto tiene cada orden?

Answers

Answer 1

Answer: orders are a, b, c, lets write equations to represent the problem's info:
a + b = 150
b + c = 100
a + c = 150
so we have 3 unknowns and 3 equations, so we can solve.
Use the first equation:
a + b = 150
a = 150 - b
and substitute in the 3rd:
a + c = 150
150 - b + c = 150
then
b = c
and we can substitute that in the original equation:
b + c = 100
2b = 100
b = 50
c = 50
and substitute in the first equation:
a + b = 150
a = 150 - b = 150 - 50
a = 100
then a = 100, b = c = 50

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%. How many total employees does the company now have?

Answers

Answer:

The total number of employees company have now are 531 .

Step-by-step explanation:

As given

A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%.

18% is written in the decimal form .

$= (18)/(100)$

= 0.18

Increase in number of employees = 0.18 × Number of employees in company .

= 0.18 × 450

= 81

Total number of employees company have now = Number of employees + Increase in number of employees

= 450 + 81

= 531

Therefore the total number of employees company have now are 531 .

You just multiply 450 by .18 and it'll give you the 18% you have to add to 450.
So the equation would look like:

450(.18)=81

Which you then add:

450+81= 531

So 531 is your total!
