One irrational number is π, also known as pi. A rational number is one that can be written as a ratio of two integers (whole numbers). Pi goes on forever, so it can't be written as a ratio. Therefore, π is irrational.
Answer:
they did not have enough materials
Step-by-step explanation:
By definition, the pitch of a roof is its vertical rise divided (In this case is 7 feet) by its horizontal measurement, which is called "Run" (42 feet). Therefore, you can calculate the pitch of this roof (P) by applying the following steps:
P=Tan^-1(Rise/Run) Rise=7 feet
Run=42 feet
When you substitute these values into the formula P=Tan^-1(Rise/Run), you obtain:
P=Tan^-1(Rise/Run)
P=Tan^-1(7/42) P=9.46º
