Answer:

  • 64 = p - 9.75
  • p = 73.75

Step-by-step explanation:

A value that is 9.75 less than p can be represented by the expression ...

  p - 9.75

We are told that value is equal to 64, so the equation is ...

  64 = p - 9.75

__

This equation is solved by adding 9.75 to both sides.

  64 +9.75 = p -9.75 +9.75

  73.75 = p

The store price is $73.75.

Answer:

Length (L) = 72 feet

Step-by-step explanation:

From the question given above, the following data were obtained:

Period (T) = 9.42 s

Pi (π) = 3.14

Length (L) =?

The length of the pendulum can be obtained as follow:

T = 2π √(L/32)

9.42 = (2 × 3.14) √(L/32)

9.42 = 6.28 √(L/32)

Divide both side by 6.28

√(L/32) = 9.42 / 6.28

Take the square of both side

L/32 = (9.42 / 6.28)²

Cross multiply

L = 32 × (9.42 / 6.28)²

L = 72 feet

Thus, the Lenght is 72 feet
