  • The operating system is a low-level software that supports a <em>computer’s basic functions</em>, such as <u>scheduling tasks and controlling peripherals</u> while the computer architecture has the <em>address bus bar</em>. This bus carries <u>signals related to addresses between the processor and the memory. </u>
  • The interface between <em>a computer’s hardware and its software</em> is its Architecture while An operating system (OS) is<u> system software that manages computer hardware and software resources and provides common services for computer programs.</u>

A hardware supplier manufactures three kinds of​ clamps, types​ A, B, and C. Production restrictions force it to make 10 more ty
Rufina [12.5K]

Answer:

A = 120

B = 40

C = 70

Solution:

As per the question:

Manufacturer forced to make 10 more type C clamps than the total of A and b:

10 + A + B = C                (1)

Also, 3 times as many type B as type A clamps are:

A = 3B                             (2)

The total no. of clamps produced per day:

A + B + C  = 330              (3)

The no. of each type manufactured per day:

Now, from eqn (1), and (3):

A + B + 10 + A + B = 330

2A + 2B = 320

A + B = 160                       (4)

Now, from eqn (2) and (4):

3B + B = 160

B = 40

Since, A = 3B

A = 3\times 40

A = 120          

Put the values of A and C in eqn (3):

120 + 40 + C = 330

C = 70
