An electronics company has two production facilities, denoted A and B. During an average week, facility A produces 2000 computer
kozerog [31]

Answer:

8 weeks of production from A and 4 weeks of production of B required to produce 28,000 monitors and 132,000 televisions.

Step-by-step explanation:

Let the number of weeks of production for team A be x and for team B be y.

In a week, facility A produces 2,000 computer monitors.

In a week ,facility A produces 3,000 computer monitors.

Total monitors to be produced = 28,000

2000x+3000y=28,000

2x+3y=28..[1]

In a week, facility A produces 10,000 flat panel televisions.

In a week ,facility A produces 13,000 flat panel televisions.

Total flat panel televisions to be produced = 132,000

10,000x+13,000y=132,000

10x+13y=132..[2]

Solving equation [1] and [2] by eliminationg method.

5 × [1] + (-1) × [2]

10x+15y=140

-10x-13y=-132

y = 4

x = \frac{28-3\times 4}{2}=\frac{16}{2}=8

8 weeks of production from A and 4 weeks of production of B required to produce 28,000 monitors and 132,000 televisions.

An engineer estimated the weight of a steel beam to be 600 pounds. The actual weight of the beam was 639 pounds. Find the absolu
ser-zykov [4K]

Answer:

Absolute: 39 pounds

Relative: 6.5%

Step-by-step explanation:

To find the absolute difference, we simply have to see by how much pounds the estimation was off.

The real measure was 639 pounds, the estimated weight was 600.

D = 639 - 600 = 39 pounds.

For the percent of error, we divide the absolute difference (39) by the real value (639) and we'll get the % of error.  So,

%D = 39 / 600 = 0.0610, so 6.1%

We don't need to round it to the nearest tenth, since it's already to that precision level.
