Pete and Marsha are going to buy a swimming pool. Mike wants a rectangular one that is 18 feet wide, 20 feet long, and 6 feet de
maks197457 [2]

Answer:

The pool that they buy is the circular pool which Marsha wants

The cost of the circular pool is $471.25

Step-by-step explanation:

The parameters of the swimming pools which each of Pete and Marsha wants to buy is given as follows;

The dimensions of the pool Pete wants = 18 feet wide, 20 feet long and 6 feet deep

The dimensions of the circle shaped pool Marsha wants = 20 feet across and 6 feet deep

The price of water, P = 25 cents per cubic foot

The pool they decide to buy = The pool that costs less to fill

The volume of water to fill the pool Pete wants, V₁ = 18 ft. × 20 ft. × 6 ft. = 2,160 ft.³

The cost of filling the pool Pete wants, C₁ = V₁ × P

∴ C₁ = 2,160 ft.³ × 25cents/ft.³ = 54,000 cents = 540 Dollars

The volume of water to fill the pool Marsha wants, V₂ = π·(20 ft.)²/4 × 6 ft. ≈ 1,884.96 ft.³

The cost of filling the pool Marsha wants, C₁ = V₁ × P

∴ C₁ ≈ 1,884.96 ft.³ × 25 cents/ft.³ ≈ 47,124 cents = 471.24 Dollars

The pool that they buy is the circular pool that Marsha wants and it costs $471.24 to fill

The sum of three consecutive integers is -51 what is the value of the smallest number
zubka84 [21]

Answer: Let's say the first number is x, the next one is x+1, and so on

Step-by-step explanation:

x + (x + 1) + (x + 2) = -51

x + x + 1 + x + 2 = -51

3x + 3 = -51

3x = -54

x = -18

11. One card is drawn from an ordinary deck of 52 cards. Find the probabilities of drawing the following.
Scilla [17]

Answer:

  1. 3/4
  2. 4/13
  3. 7/26
  4. 2/13
  5. 5.52

Step-by-step explanation:

<u>(a)</u>

  • Probability (A heart or a black card) = 13 + 26 / 52
  • Probability (A heart or a black card) = 39/52
  • Probability (A heart or a black card) = 3/4

<u>(b)</u>

  • Probability (A heart or a jack) = 13 + 3 / 52
  • Probability (A heart or a jack) = 16/52
  • Probability (A heart or a jack) = 4/13

<u>(c)</u>

  • Probability (A heart and the ace of clubs) = 13 + 1 / 52
  • Probability (A heart and the ace of clubs) = 14/52
  • Probability (A heart and the ace of clubs) = 7/26

<u>(d)</u>

  • Probability (A 9 or a jack) = 4 + 4 / 52
  • Probability (A 9 or a jack) = 8/52
  • Probability (A 9 or a jack) = 2/13

<u>(e)</u>

  • Probability (The 9 of hearts or a jack) = 1 + 4 / 52
  • Probability (The 9 of hearts or a jack) = 5/52

A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)
Hatshy [7]

The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

C=2\pi r

putting the values

75.36 = 2*3.14*r\\75.36 = 6.28r

Dividing both sides by 6.28

\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm

The area of circle is given by:

A = \pi r^2

Putting the values

A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2

Hence,

The area of flying disk is 452.16 square centimeters
