Answer:

difference\hspace{0.2cm} between\hspace{0.2cm} the\hspace{0.2cm} two\hspace{0.2cm} areas\hspace{0.2cm} =\hspace{0.2cm} 9(2\sqrt{3} -\pi)

Step-by-step explanation:

i) area of circle = \pi \times r^{2}  = 9\pi \hspace{0.1cm} where \hspace{0.1cm}r = 3.

ii) therefore side of hexagon, a = 2\sqrt{3}

iii) therefore area of hexagon, A = \frac{3\sqrt{3} }{2} a^{2}  =  \frac{3\sqrt{3} }{2} \times 12 = 18\sqrt{3}

iv) difference between the two areas in iii) and i)  =9(2\sqrt{3} -\pi)

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. x2+3/2x
denis23 [38]

Answer:

The added term needed for that expression to be a square is 9/16.

Step-by-step explanation:

We're provided with two terms, and asked to add an additional term to make this a perfect square.  For this to work, the term needs to be a scalar value that is the square of half the coefficient of the second term.

That coefficient is 3/2, so half of that is 3/4, and its square is 9/16.

If we tack that on the end then, we get:

x^2 + \frac{3x}{2} + \frac{9}{16}\\=(x + \frac{3}{4})^2

To confirm the answer, let's expand it and see if we get the original expression:

(x + \frac{3}{4})^2\\= (x + \frac{3}{4})(x + \frac{3}{4})\\= x^1 + \frac{3x}{4} + \frac{3x}{4} + \frac{9}{16}\\= x^2 + \frac{6x}{4} + \frac{9}{16}\\=x^2 + \frac{3x}{2} + \frac{9}{16}

So 9/16ths is the scalar that needs to be added on the end.

Stem and leaf plots, what is the mode median and range of the scores ​
frez [133]

Answer:

Mode = 81,  Median = 81 and Range = 39.

Step-by-step explanation:

The mode  is the most occurring value which is 81.

The median is also 81. There are a total of 19 numbers arranged in ascending order so the median is the 10th number.

The range is the highest - lowest number = 100 - 61 = 39.

CAN SOMEONE PLS ANSWER-If W(- 10, 4), X(- 3, - 1) , and Y(- 5, 11) classify AEXY by its sides . Show all work to justify your an
AnnZ [28]

Answer:

  • WX = \sqrt{74} \approx 8.6023253\\\\
  • XY = 2\sqrt{37} \approx 12.1655251\\\\
  • WY = \sqrt{74} \approx 8.6023253\\\\
  • Classify:  Isosceles

============================================================

Explanation:

Apply the distance formula to find the length of segment WX

W = (x1,y1) = (-10,4)

X = (x2,y2) = (-3, -1)

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-3))^2 + (4-(-1))^2}\\\\d = \sqrt{(-10+3)^2 + (4+1)^2}\\\\d = \sqrt{(-7)^2 + (5)^2}\\\\d = \sqrt{49 + 25}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\

Segment WX is exactly \sqrt{74} units long which approximates to roughly 8.6023253

-------------------

Now let's find the length of segment XY

X = (x1,y1) = (-3, -1)

Y = (x2,y2) = (-5, 11)

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-3-(-5))^2 + (-1-11)^2}\\\\d = \sqrt{(-3+5)^2 + (-1-11)^2}\\\\d = \sqrt{(2)^2 + (-12)^2}\\\\d = \sqrt{4 + 144}\\\\d = \sqrt{148}\\\\d = \sqrt{4*37}\\\\d = \sqrt{4}*\sqrt{37}\\\\d = 2\sqrt{37}\\\\d \approx 12.1655251\\\\

Segment XY is exactly 2\sqrt{37} units long which approximates to 12.1655251

-------------------

Lastly, let's find the length of segment WY

W = (x1,y1) = (-10,4)

Y = (x2,y2) = (-5, 11)

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-10-(-5))^2 + (4-11)^2}\\\\d = \sqrt{(-10+5)^2 + (4-11)^2}\\\\d = \sqrt{(-5)^2 + (-7)^2}\\\\d = \sqrt{25 + 49}\\\\d = \sqrt{74}\\\\d \approx 8.6023253\\\\

We see that segment WY is the same length as WX.

Because we have exactly two sides of the same length, this means triangle WXY is isosceles.

. Alex bought a new bike last weekend. It was $185 and he had to pay tax at a rate of 8%. How
egoroff_w [7]

Answer:

$14.80

Step-by-step explanation:

Original bike price: $185

Tax: 8% OR 0.08 as a DECIMAL

To find your answer, multiply the bike price by the DECIMAL (number) tax amount:

185 x 0.08

= 14.8

Therefore, Alex paid $14.80 in tax.
