Givens
You have 4 suits in a deck of cards
There are 13 cards in each suit.
You draw a card that is one of 4, 5, 6, 7, 8, 9   There are six cards in each suit that will bring you success.

Formula
Number of cards in a deck = 4 * 13.
Number of cards that are a success = 4*6

P(4 - 9) = 4 * 6 / 4 * 13 = 6/13 = 0.4615 

Answer
P(4_9) = 0.4615 

If you have choices, please list them.

The circumference of a circle is 15π ft. What is the area, in square feet? Express your answer in terms of π.
DerKrebs [107]

Answer:

  • Area of the circle is 56.25π square feet.

Step-by-step explanation:

<u>Given that</u>:

  • The circumference of a circle is 15π ft.

<u>To Find</u>:

  • What is the area, in square feet?

<u>We know that</u>:

  • Circumference of a circle = 2πR
  • Area of a circle = πR²

Where,

  • Radius is denoted as R.

<u>Finding the radius of the circle</u>:

Circumference of a circle = 15π

⟶ 2πR = 15π

⟶ 2πR = 2π × 7.5

Cancelling 2π.

⟶ R = 7.5

∴ Radius of the circle = 7.5 ft.

<u>Finding the area of the circle</u>:

⟶ Area = πR²

⟶ Area = π(7.5)²

⟶ Area = π × 7.5 × 7.5

⟶ Area = π × 56.25

⟶ Area = 56.25π

∴ Area of the circle = 56.25π ft.²

kobusy [5.1K]

Answer:

Number of 1 $ bill = 20

Number of 5 $ bill = 6

Explanation:

 Let p represent number of one dollar bolls and q represent number of five bills.

A total of 26 bills are in a cash box.

      p + q = 26    ------------------------- Equation 1

The total amount of cash in the box is $50

      p + 5q = 50    ------------------------- Equation 2

Equation 2 - Equation 1,

        p + 5q - p -q = 50 - 26

        4q = 24

          q = 6

Substituting in equation 1.

         p + 6 = 26

         p = 20

Number of 1 $ bill = 20

Number of 5 $ bill = 6
