Explanation

1 Kilobyte (KB) = 1024 bytes

One Megabyte (MB) = 1024 Kilobytes (KB

One Gigabyte (GB) =  1024 Megabytes MB

One Terabyte (TB)= 1024 gigabytes (GB).

The size of information in the computer is measured in:

Kilobytes (KB)

Megabytes (MB)

Gigabytes (GB)

Terabytes (TB)

Explanation

1 TB equals 1,000 gigabytes  or 1,000,000 megabytes (MB).

Individual external hard drives often start at 1 TB of storage, with options that go up to 4 TB.

Explanation

Let's denote the two integers as x and y, where x > y:

Given x - y = 3 and x² + y² = 89.

From x - y = 3, we get x = y + 3.

Substitute x in the second equation:

(y + 3)² + y² = 89

y² + 6y + 9 + y² = 89

2y² + 6y - 80 = 0

y² + 3y - 40 = 0

(y + 8)(y - 5) = 0

y = -8 (not possible since y is positive) or y = 5.

If y = 5, then x = y + 3 = 8.

Check: 8² + 5² = 64 + 25 = 89.

The integers are 8 and 5.

Explanation

Inverse Proportion:

When one quantity increases, the other decreases in such a way that their product remains constant.

Example: Speed increases → Time to cover the same distance decreases.

Direct Proportion:

When one quantity increases, the other also increases at the same rate.

Example: More hours worked → More wages earned.

Explanation

we have given 120km/hr

1 hour = 60 min

then,

120/60 = 2

then 2 × 15 = 30 .

and that is our answer.

so, 30km/min

Explanation

A circle does not have a side and hence no vertex.

Hence, "circle" is different from all other given shapes.

 the square has 4 sides,

A hexagon has 6 sides,

triangle has 3 sides. 

Explanation
