What is the meaning of the bottom number if the pitch of a roof is 2/7
Y_Kistochka [10]

Based on the given value of pitch (slope), the bottom number simply means the horizontal distance an object runs through.

<h3>What is a pitch?</h3>

A pitch is also referred to as slope and it can be defined as the ratio of the vertical distance (rise) measured to the horizontal distance (running) measured.

<h3>How to determine the pitch (slope) of a roof?</h3>

Mathematically, the pitch (slope) of a roof can be calculated by using this formula:

Pitch (slope) = V/H

<u>Where:</u>

  • V is the rising vertical distance of an object.
  • H is the horizontal distance an object runs through.

<u>Given the following data:</u>

Vertical distance (rise) = 2 units.

Horizontal distance (running) = 7 units.

By critically observing the given value of pitch (slope) as 2/7, we can infer and logically deduce that the bottom number simply means the horizontal distance an object runs through.

1. Jadyn started off his long division problem incorrectly. What is his mistake?
Anastaziya [24]

The mistake Jadyn made in the long division is

  • Mistake in subtraction
  • the first quotient

<h3>What is long division ?</h3>

Long division refers to a way of dividing large numbers

performing the long division correctly gives

divisor    dividend     quotient     multiplication    subtraction  new dividend

8             335              40               8 * 40 = 320     335 - 320       15          

8             15                 1                   8 * 1 = 8            15 - 8                7  

8             70                0.8               8 * 8 = 64      70 - 64                6

8             60                0.07             8 * 7 = 56       60 - 56               4

8             40                0.005           8 * 5 = 40       40 - 40               0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875
