If there are 10 billion transistors (each of a square shape) uniformly (without space) distributed on a silicon chip with the sq
Karo-lina-s [1.5K]

Answer:

the transistors have L=1 mm of linear size

Step-by-step explanation:

For the silicon chip the area is A=1 cm² and for the transistors the area is At=L² (L=linear size) . Then since N= 10 billion transistors of area At should fit in the area A

A=N*At

A=N*L²

solving for L

L= √(A/N)

Assuming that 1 billion=10⁹ (short scale version of billion), then

L= √(A/N) = √(1 cm²/10⁹) = 1 cm / 10³ = 1 mm

then the transistors have L=1 mm of linear size

Answer:

  • Library 2 charges more for each book loaned.
  • Library 1 has a cheaper subscription fee.

Step-by-step explanation:

Based on the table, we can write the equation for the cost of borrowing from Library 2 using the two-point form of the equation of a line:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

for (x1, y1) = (2, 15.50) and (x2, y2) = (8, 26) this equation becomes ...

  y = (26 -15.50)/(8 -2)(x -2) +15.50 . . . . . fill in the values

  y = (10.50/6)(x -2) +15.50 . . . . . . . . . . . . simplify a bit

  y = 1.75x -3.50 +15.50 . . . . . . simplify more

In the above, we have x = number of books; y = cost. We can use "n" and "C" for those, respectively, as in the equation for Library 1. Then the monthly cost for Library 2 is ...

  C = 12 + 1.75n . . . . . . . arranged to the same form as for Library 1

_____

Now, we can answer the questions.

Library 2 charges more for each book loaned. (1.75 vs 1.50 for Library 1)

Library 1 has a cheaper subscription fee. (10 vs 12 for Library 2)

_____

The numbers in the cost equations are ...

  C = (subscription fee) + (cost per book loaned)·n

Andrei [34K]

Answer:

1 = t/45 + t/105

Step-by-step explanation:

Greg's father mow a lawn in 45 minutes that means that he mow in a rate of 1/45

Greg mow a lawn in 1 hour 45 minutes (105 minutes) that means that he mow in a rate of 1/105

If they mow a lawn in t minutes that means the rate is 1/t

Then, the rate in which they mow a lawn has to be equal to the sum of the rate individually as follows

1/t = 1/45 + 1/105

1 = t/45 + t/105
