# Find the value of L. Perimeter = 20. Width is 6. So what is L? On a square

QUESTION POSTED AT 05/12/2019 - 05:54 PM

Well first of all, that's not a square. On a square, all 4 sides are

the same, and the length is the same distance as the width. If the

width of a square is 6, and all four sides are the same, then the

perimeter is (4 x 6) = 24.

So the shape in your question may be a rectangle, but it's definitely

not a square one.

The perimeter is the distance an ant has to walk if you put him down

on one corner and he walks all the way around the shape until he gets

back to where he started from.

That's the perimeter.

If you set the ant down on the corner of a rectangle, then he walks the

length, then the width, the the length again, then the width again, and

he's back where he started.

That was 2 lengths and 2 widths ... the perimeter of every rectangle.

Take 2 widths away from the perimeter, and you have 2 lengths left. OK ?

You said that the width of your rectangle is 6. Two widths is 12.

Take the 2 widths away from the perimeter, and you're left with (20 - 12) = 8.

But that's 2 lengths !

So the length is half of 8 =

HhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhGiven:

trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long

⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in

⇒ 77inches by 105 inches

⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long

⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in

⇒ 160 inches by 92 inches

⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long

⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in

⇒ 66 inches by 148 inches

⇒ 9,768 square inches

130 square feet convert to square inches.

130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches

Perimeter = 2(160 + 117)

P = 2(277)

P = 554 inches

P = 2(277)

P = 554 inches

**Answer:**

The probability is 0.152

**Step-by-step explanation:**

We know that in this town 39% of all voters are Democrats. Therefore, the probability of a randomly selected voter being a Democrat is

The experiment of randomly select voters for a survey is called a Bernoulli experiment (under some suppositions). We suppose that exist independence in this randomly selection of voters. We also suppose that there are only two possibilities for the voter : It is Democrat or not.

Now the variable X : ''The randomly selected voter for a survey is Democrat'' is a Binomial random variable.

X ~ Bi (n,p)

The probability function for the BInomial random variable X is :

Where ''n'' is the number of Bernoulli experiments (In this case n = 2 because we randomly selected two voters)

P(X=x) is the probability of the variable X to assumes the value x

(nCx) is the combinatorial number define as

p = 0.39 in this exercise.

We are looking for P(X=2) ⇒

If we round to the nearest thousandth the probability is 0.152

QUESTION POSTED AT 01/04/2020 - 01:39 PM

X = multiplication

h = height

r^2 = radius squared

Formula of a cylinder: Pi x r^2 x height

So, if 176 = 3.14... times 4^2 times h

Then, 176 = 3.14 times 16h

Next, 176 = 50.24h

Finally, 3.5 = h

You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.
