The length of a rectangular deck is 5 times it’s width. If the decks perimeter is 36feet, what is the deck area?

Answers

Answer:

45

Step-by-step explanation:

P = 2(L+W)

36 = 2(5W + W)

36 = 10W + 2W

36 = 12W

W = 3

5W = 5(3) = 15

15 x 3 = 45

The area of a rectangular deck is 45 square feet.

Given that, the length of a rectangular deck is 5 times it’s width.

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

The decks perimeter is 36 feet

Let the width of a deck is w, then the length of a deck is 5w.

Now, 2(5w+w)=36

⇒ 6w=18

⇒ w=3 feet

So, length=5w=15 feet

Area =15×3

= 45 square feet

Therefore, the area of a rectangular deck is 45 square feet.

When a standard pair of six sided dice are rolled, what is the probability of getting a 6?
(Express your answer as a decimal rounded to the thousandsth place.)

Answers

Answer:

0.5 because it has a total of 6 sides

Probability of getting a 6 is equal to
1 - the probability of not getting a six.
The probability of not getting a six on a single roll is 5/6. The probability of not getting a 6 for 2 rolls is (5/6)^2.
The probability of getting a six is

1 - (5/6)^2 = 11/36.

Step-by-step explanation:

A solution that shows up as a result of the process of solving an equation, but that does not work in the original equation, is called "an extraneous solution".

Radical and rational expression equations can have extraneous solutions. For radical equations, they are typically ones that require a negative square root (or negative root of even index). For rational expression equations, they typically involve "excluded" values, values that make a denominator be zero.

A pump fills an empty pool at a rate of 500 cubic meters per hour. If one liter is equivalent to one cubic decimeter and 1 meter is equal to 10 decimeters, how many liters of water are in the pool half an hour after the pump starts?

Answers

If a liter equals a cubic decimeter and a meter equals ten decimeters, then 250,000 liters of water is filled in the pool in half an hour.

What is meant by cubic decimeter?

1000 cubic centimeters make up one cubic decimeter. Repeating this procedure would allow us to translate between cubic centimeters and meters or between cubic decimeters and meters. We must keep in mind three conversions. 1000 cubic centimeters is equal to one cubic decimeter.

1 cubic meter = 1000 liters

because, 1 liter = 1 decimeter³

1 meter = 10 decimeters

1 decimeter= 0.1 meters

1 liter = 0.1³ meter³

1 m³ = 1000 liters

Given:

In 1 hour the amount of water filled = 500 cubic meters

In half an hour the amount of water filled = 250 cubic meters

= 250,000 liters.

Therefore, 250,000 liters of water exists filled in the pool in half an hour.

Here is the explanation. As Hye drinks 4/3 gallons of water in 11/2 hours, we have a constant rate. There are 12 thirds in 4, so we are trying to find how long it takes Hye to drink 12/3 gallon. In this case, 4/3x3=12/3, so we multiply 11/2 by 3 as well, which gives us 33/2 hours. 33/2 in decimal form is 16.5 hours. Hope it helps!
