Answer:
Step-by-step explanation:
If cost is directly proportional to speed, then the equation for this is
£ = ks, where k is the constant of proportionality. We need to solve for this first.
400 = k4 so
100 = k. Now we will use that k value in the next equation to find the cost of a 6GHz processor:
£ = (100)(6) so
£ = 600
Answer: 8 feet
Step-by-step explanation:
Since, the scale of the drawings is 1 inch to 4 feet.
![\implies 1\text{ inch } = 4\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%201%5Ctext%7B%20inch%20%7D%20%3D%204%5Ctext%7B%20feet%7D)
By multiplying both sides by 2,
![\implies 2\times 1\text{ inch } = 2\times 4\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%202%5Ctimes%201%5Ctext%7B%20inch%20%7D%20%3D%202%5Ctimes%204%5Ctext%7B%20feet%7D)
![\implies 2\text{ inches} = 8\text{ feet}](https://tex.z-dn.net/?f=%5Cimplies%202%5Ctext%7B%20inches%7D%20%3D%208%5Ctext%7B%20feet%7D)
Thus, the actual length of the table = 8 feet.
