Explanation

√2 cannot be written as a ratio of two integers, so it is an irrational number.

Its decimal form is non-terminating and non-repeating (≈ 1.414...).

Explanation

4 TESTS AVERAGE IS 60. SO IF WE SUM THE TOTAL VALUE THEN

60*4=240

5 TESTS AVERAGE IS 58.SO IF WE SUM THE TOTAL VALUE THEN

58*5=290.

THEN TAKE THE DIFFERENCE OF SUM YOU GET

290-240= 50.

Explanation

A composite number is a natural number greater than 1 that has more than two positive divisors.

Both 6 and 4 are composite numbers, as they can be divided by 1, themselves, and other numbers.

However, 2 is a prime number because it only has two divisors: 1 and itself.

Explanation

"X" represents 10 and "V" represents 5.

So together they form 15 (10 + 5 = XV).

Roman numerals for the given numbers:

• 1 - I
• 5 - V
• 10 - X
• 50 - L
• 100 - C
• 500 - D
• 1000 - M

Explanation

The answer after we divide one number by another. dividend ÷ divisor = quotient.

Example: in 12 ÷ 3 = 4, 4 is the quotient.

Explanation

= - 4 x - 4 x - 4 + 4 x 4

= - 64 + 16

= - 48 

Explanation

An improper fraction is a fraction in which the numerator is greater than the denominator. Let's evaluate each fraction in the list:

1. $frac{15}{7}$: 15 is greater than 7, so this fraction is improper.
2. $frac{14}{9}$: 14 is greater than 9, which is also an improper fraction.
3. $frac{13}{7}$: 13 is greater than 7, so this is also an improper fraction.
4. $frac{12}{8}$: 12 is greater than 8, so this is also an improper fraction.

Since all four fractions have numerators greater than their denominators, all of them are improper fractions:

Explanation

5 ×  5 = 25

25 ×  5 = 125

125 ×  5 = 625

625 ×  5 = 3125

3125 ×  5 = 15625
