Perusahaan sepatu pada tahun ke-2 mampu memproduksi sebanyak 1.200 pasang. Jika perusahaan tersebut mampu menaikkan produksinya 1,5 kali lipat dari tahun sebelumnya maka jumlah produksi selama 4 tahun adalah...

6,500 pairs

Step-by-step explanation:

The question in English is

Footwear companies in the second year were able to produce 1,200 pairs. If the company can increase its production 1.5 times over the previous year, the total production for 4 years is

we know that

In the second year the company produced 1,200 pairs

so

In the first year, the total pairs produced is equal to divide the total pairs produced in the second year by 1.5

In the third year, the total pairs produced is equal to multiply the total pairs produced in the second year by 1.5

In the fourth year, the total pairs produced is equal to multiply the total pairs produced in the third year by 1.5

therefore

The total production in 4 years is equal to

the square root of what number? if you add that, then someone will probably answer the question.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
