How does the precise nature of mathematics OR the imprecise nature of language sometimes get in the way of understanding problem

Degger [83]

Answer:

This is because mathematics uses some theories that helps to change words to equations. for example, a tree of height 50m makes a shadow on the ground. an observer standing at angle of 30 degrees, calculate the distance of the man to the tree. we use the the formula, tan (30)=opp/adj

$1 \div \sqrt{3 } = 50 \div x$

$x = 50 \sqrt{3} m$

Answer:

c = 9/16

Step-by-step explanation:

<h3>step1</h3>

(a-b)²

a² - 2ab + b²

here a = x

b = ?

so

x² - (2)(x)(?) + ?²

Now we can see that -(2x)? = -3x/2

-2x? = -3x/2

cancel -x on both sides

2? = 3/2

? = 3/2 * (2)

? = 3/4

so b = 3/4

<h3>step2</h3>

(x² - 3x + 9/16) = (x-3/4)²

so from the expression we can see that C = 9/16

Answer: a) 92 yards, b) 29.29 yards and 672.99 sq. yd.

Step-by-step explanation:

Since we have given that

Area of square pen = 529 sq. yd

Let the length of each side be 'a'.

As we know the formula for "Area":

$Area=a^2\\\\529=a^2\\\\\sqrt{529}=a\\\\a=23\ yd$

So, the perimeter of the square pen is given by

$4\times s=4\times 23\\\\=92\ yd$

So, perimeter of square pen = Perimeter of round pen

$92=2\pi r\\\\92=2\times 3.14\times r\\\\\dfrac{92}{2}=3.14\times r\\\\\dfrac{46}{3.14}=r\\\\14.64=r$

So, the diameter of round pen is $2\times r=2\times 14.64=29.29\ yd$

And the area of round pen is

$\pi r^2\\\\=3.14\times (14.64)^2\\\\=672.99\ sq.\ yd$

Hence, a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
