Math and Arithmetic

To find the number of 2-number combinations that can be made with the numbers 1 through 6, we use the combination formula ( C(n, r) = \frac{n!}{r!(n-r)!} ), where ( n ) is the total number of items to choose from and ( r ) is the number of items to choose. Here, ( n = 6 ) and ( r = 2 ). Thus, the number of combinations is ( C(6, 2) = \frac{6!}{2!(6-2)!} = \frac{6 \times 5}{2 \times 1} = 15 ). Therefore, there are 15 different 2-number combinations that can be made with the numbers 1 to 6.

The weight of an object can be calculated using the formula ( W = m \times g ), where ( W ) represents weight, ( m ) is the mass of the object, and ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 ) on Earth). This formula indicates that weight is the product of an object's mass and the gravitational force acting on it.

If this is a speed problem, use the formula: distance = speed x time. Other than that, you can't convert from units of distance to units of time.

It can be in 3 answer form:

3 (rounded to the nearest whole number)

2.9 (rounded to 1 decimal place)

2.94 (already rounded to 2 decimal places)

The smallest number in the group is 0.88. When comparing decimal numbers, you look at the digits to the left of the decimal point first. In this case, 0.88 has the smallest value to the left of the decimal point. The other numbers, such as 0.999, 0.999999, 0.9, and 1.2, all have larger values to the left of the decimal point, making 0.88 the smallest in this group.

1 x 21 = 21

21 x 1 = 21

3 x 7 = 21

7 x 3 = 21

2 X 3^(2) = 2 x 9 = 18

or

( 2 x 3) ^(2) = 6^(2) = 36

So please be careful on gow you describe your sum.

Impossible to say without knowing the density .

Grams is a measure of MASS/WEIGHT

ml(Millilitres) is a measure of VOLUME.

The two points are (2,16) & ( 5,4) in ( x,y) form .

Use the eq'n

m = [y(1) - y(2)] / [ x(1) - x(2)]

These numbers are labels , NOT factors/indices.

Substituting

m = [16 - 4] / [ 2 - 5]

m = [ 12] / [ -3]

m = -4 The slope.

Being negative, on a graph, the line will go down from left to right.

Starting and running more than one program at a time is known as multitasking. This allows a computer to manage multiple processes simultaneously, enabling users to switch between applications smoothly. Multitasking can be achieved through time-sharing, where the CPU rapidly switches between tasks, or through parallel processing, where multiple processors handle different tasks at the same time. This functionality enhances efficiency and improves user experience.

The word' congruent' means 'exactly the same' , both in size, area and shape.

Since a triangle has 3 sides, and a square has four sides, they are NEITHER the same size NOR shape.

They are NOT congruent, but INCONGRUENT.

Do NOT confuse with 'similar'. 'Similar' means same shape, same angles, BUT different area.

Both terms have specific mathematical meanings, so be careful.

1.29 GB (gigabytes) is equivalent to 1,290 megabytes (MB) or about 1,310,720 kilobytes (KB). In terms of storage, it can hold approximately 1,000 songs, around 300,000 average-sized photos, or several hours of high-definition video, depending on the file size and quality.

In the story "The Daughter of the Sun," the empty box symbolizes lost hope and the consequences of greed. The protagonist learns that the box, once thought to hold great treasures, is devoid of material wealth, reflecting the idea that true value lies not in physical possessions but in love, relationships, and personal growth. The emptiness serves as a poignant reminder of the importance of appreciating what one has rather than coveting what one does not.
