Answer:

option B

2

Step-by-step explanation:

Given in the question

DO,h(7, 9) → (14, 18)

Formula to use

<h3>√(x1-x2)²+(y1-y2)²</h3>

distance formula = √((7-0)²+(9-0)²) = √(7²+9²) = √130

distance formula = √((14-0)²+(18-0)²) = √(14²+18²) = 2√130

Scale factor

√130 = 2√130

Working simultaneously and independently at an identical constant rate, 4 machines of a certain type can produce a total of x un
Jobisdone [24]

Answer:

B. 18

Step-by-step explanation:

The 4 machines can produce x units in 6 days. This means they have a daily total rate of x/6 units per day.

Since the machines are similar and that they work at the same rate, this means that the individual rates of each machine would be x/6/4 = x/24 units per day.

Now we are looking at producing 3x units in 4 days. This means that we want to produce 3x/4 units in a single day. Now, since each machine would work at a rate of x/24, we need to know the number of machines we need. To know this number, we simply divide what is to be achieved by the individual rate:

This is 3x/4 divided by x/24. This mathematically means 3x/4 * 24/x = 18 machines
