KengaRu [80]

Answer:

Repeaters.

Step-by-step explanation:

This is essential to effective communication because your EMS system must use Repeaters.

These are machines used to carry signals across a great distance. We may be in ambulances or put around an EMS network in different areas. The repeater receives and re transmits signals from lower power systems, such as mobile and handheld phones, to a higher power.

how long will it take 14 machines to complete the task, given that 8 machines can complete the same task in 7 days?
torisob [31]

Answer:

4 days

Step-by-step explanation:

If 8 machines can complete a task in 7 days, how long will 14 machines take?

So, it is obvious that if the number of machines increases, the number of days taken to complete the task decreases; thus proving that this is an indirect / inverse proportion.

Let's take <em>x</em> as the number of days we need to find out.

 8 machines : 7 days

14 machines : <em>x</em> days

14 × <em>x </em>= 8 × 7

14<em>x </em>= 56

x = \frac{56}{14}

x = 4

How would I go about solving 12,15,18 thanks
grigory [225]
For 12, you would do 90=4x+42, and 48=4x, and x=12
for 15, you would do 90=8x+66, and 24=8x, and x=3
for 18, you would do 90=3x+57, and 33=3x, and x=11
