Explanation

79 × 79 = 6,241

Explanation

x + y = 67 ... (equation 1)

x - y = 3 ... (equation 2)

where x and y are the two numbers.

We can solve this system of equations by adding equation 1 and equation 2, which eliminates y:

2x = 70

Dividing both sides by 2 gives:

x = 35

Now that we have x, we can substitute it into equation 1 to find y:

35 + y = 67

Subtracting 35 from both sides gives:

y = 32

So, the two numbers are 35 and 32.

Explanation

Bevel gears are specifically designed to transmit rotational power between shafts that intersect at a 90-degree angle.

Spur gears only transmit power between parallel shafts

Helical gears can transmit power between parallel or non-parallel shafts, but are not the primary choice for a 90-degree right-angle power transfer.

9  2]  FIND TRANSPOSE OF A MATRIX?

The additive inverse of a matrix A is a matrix -A, where each element is the negative of the corresponding element in A.

Given:  

A =  

[ -5 8 ]  

[  6 -2 ]

Then,  

-A =  

[ 5 -8 ]  

[ -6 2 ] ✔

Because:  

- (-5) = 5  

- (8) = -8  

- (6) = -6  

- (-2) = 2

Explanation

Given ratio: 35 : 84

Step 1: Find the GCD (Greatest Common Divisor) of 35 and 84  

GCD of 35 and 84 is 7

Step 2: Divide both terms by 7  

35 ÷ 7 = 5  

84 ÷ 7 = 12

Simplest form: 5 : 12

Explanation

0.75 × 0.567 = 0.42525  

0.42525 ÷ 0.134 ≈ 3.172

Explanation

Solution:

Add 0.525 and 0.2:

0.525+0.2=0.725

Now, add 0.725 and 0.5:

0.725+0.5=1.225

Explanation

5 is an odd number because it is not divisible by 2.

Unlike 6, 4, and 2, which are even numbers.

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.
