vredina [299]
Okay so all you have to do is find the Area of each shape, then add them together.  Starting with the square.  Your formula is A=s4    All you have to do is plug in your number.  A=26(4) Now solve. A=104.   Now we have to find the area of a semicircle.  Your formula is ((3.14)r squared)(.5) To find the radius (r) you divide the diameter by 2, so 26/2=13     Now all you have to do is plug in your numbers.   (3.14)(13 squared)(.5)    (3.14)(169)(.5)   
(530.66)(.5)   Your final answer is:  265.33 inches squared

We know that w = 21 so:

(4x+z)(3x-w)=0\\\\(4x+z)(3x-21)=0\\\\3x-21=0\\\\3x=21\qquad|\div3\\\\\boxed{x=7}

2 2/3 of what number is 6 1/7
borishaifa [10]

2\frac{2}{3} of 2\frac{17}{56} is 6\frac{1}{7}

Solution:

Given 2\frac{2}{3} of what number is 6\frac{1}{7}.

Let us first convert the mixed fraction into improper fraction.

$2\frac{2}{3}=\frac{(2\times3)+2}{3}=\frac{8}{3}

$6\frac{1}{7}=\frac{(6\times7)+1}{3}=\frac{43}{3}

Now, let us take the unknown number be x.

$2\frac{2}{3}\times x=6\frac{1}{7}

$\frac{8}{3}\times x=\frac{43}{7}

Do the cross multiplication.

$ x=\frac{43}{7}\times\frac{3}{8}

$ x=\frac{43\times3}{7\times8}

$ x=\frac{129}{56}

Now, again change the improper fraction into mixed fraction.

$ x=2\frac{17}{56}

Hence 2\frac{2}{3} of 2\frac{17}{56} is 6\frac{1}{7}.
