3. thirty divided by a number
4.the quotient of a number and thirty
5. a number divided by thirty
6. the product of a number and thirty

1, 4, 5

Step-by-step explanation:

This is the equation:

So because 1 and 4 are right because they both describe the quotient being of h and 30. 5 is right because fractions are really just the numerators divided by denominators (h÷30).

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
