After that Divide the number that you wish to determine the percentage for

Then multiply the value from step two by 100.

In this case the answer will be 43.47

64 percent of 69 = 43.47

Answer: 43.47

Rectangle with a length of 96 inches and width of 60 inches. A rug maker wants to increase each dimension by a different amount.

mr Goodwill [35]

Answer:

The perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

Step-by-step explanation:

The question is incomplete.

The actual question should be:

A rug maker is using a patter that is a rectangle with a length of 96 inches and a width of 60 inches. The rug maker wants to increase each dimension by a different amount. Let l and w be the increases in inches of the length and width. write and simplify an expression for the perimeter of the new pattern.

Solution:

Original length of the rectangular pattern = 96 inches

Original width of the rectangular pattern = 60 inches

Let increase in length be = $l$ inches

New length of rectangle = $(96+l)$ inches

Let increase in width be = $w$ inches

New width of rectangle = $(60+w)$ inches

The perimeter of a rectangle is given by :

⇒ $2(length+width)$

Substituting the new length and width of the triangle.

⇒ $2(96+l+60+w)$

Simplifying.

⇒ $2(l+w+156)$

Using distribution.

⇒ $2l+2w+312$

Thus, the perimeter of the new rectangle in simplified expression can be given as:

$2l+2w+312$

What is the arc length of a semicircle with a radius of 14?

Deffense [45]

Answer:

Perimeter of the semicircle is the formula r(π+2).

Radius r=14 cm

So, perimeter =14(π+2)... where π= 22/7

=2(22+14)=44+28=72 cm

So , the answer is

72 I guess

Divide the binomial by the monomial to find the quotient -36x^4y + 144x^2 y^6/ -4x^2y

elixir [45]

The way that you would do this is by taking $-4x^{2}$ out of the binomial, or as I like to think about it, 'un-distributing'. :p
$-4x^{2}$ out of $-36x^{2}y$ , you end up with $12x^{2}$ .
When you take $-4x^{2}$ out of $144x^{2}y{6}$ , you get $-36y^{5}$ .
Put it together, and the solution is $12x^{2}$ - $36y^{5}$ .

Hope I helped!!

Public opinion in the large city of Bedrock is that 60 percent of the residents are in favor of increasing taxes to fund alterna

uysha [10]

Answer: 0.8461

Step-by-step explanation:

Let p be the proportion of residents are against the increase of taxes to fund alternatives to drug addiction treatment.

As per given , we have p=0.40

A random sample is taken with size : n= 400

Expecting sample proportion : $\hat{p}=\dfrac{150}{400}=0.375$

Now , the probability that more than 150 of the residents surveyed will be against increasing taxes if a random sample of 400 residents are surveyed will be :

$P(p>0.375)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.375-0.40}{\sqrt{\dfrac{0.40(0.60)}{400}}})$

$=P(z>\dfrac{0.375-0.40}{\sqrt{\dfrac{0.40(0.60)}{400}}})\ \ [\because\ z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]$

$=P(z>-1.02)=P(z-z)=P(Z$

$\approx0.8461$ [By z-table]

Hence, the approximate probability that more than 150 of the residents surveyed will be against increasing taxes if a random sample of 400 residents are surveyed is 0.8461 .
