PLEASE HELP!!!!!!! ALSO SHOW WORK

Dimas [21]

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.

Help please, show steps<br>3n/7-1=1/8

goldfiish [28.3K]

Given:

$\frac{3n}{7}-1=\frac{1}{8}$

First, let's move the -1 to the right side. When we add $1 + \frac{1}{8}$ , we get $\frac{9}{8}$ .

$\frac{3n}{7}=\frac{9}{8}$

Now we can cross multiply, multiply (3n)(8) and (7)(9)

$(3n)(8)=(7)(9)$

Simplify the left side.

$24n = (7)(9)$

Simplify the right side.

$24n=63$

Divide both sides by 24 to isolate n.

$\frac{24n}{24}=\frac{63}{24}$

Simplify.

$n=\frac{21}{8}$
