To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.

-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:

-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:

-3, -2.5, 1/5, (3 3/5), 10

In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.

The median is 1/5.

You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.

Write a rule to describe the transformation.

Angelina_Jolie [31]

Step-by-step explanation:

The function translation / transformation rules: f (x) + b shifts the function b units upward. f (x) − b shifts the function b units downward. f (x + b) shifts the function b units to the left

Rationalize the denominator and simplify. StartFraction 5 minus StartRoot 3 EndRoot Over 4 plus 2 StartRoot 3 EndRoot EndFractio

nasty-shy [4]

Answer:

$\frac{13-7\sqrt{3}}{2}$

Step-by-step explanation:

We need to rationalize the denominator of $= \frac{5-\sqrt{3}}{4+2\sqrt{3}}$ . For rationalizing we multiply the equation by $\frac{4-2\sqrt{3}}{4-2\sqrt{3}}$

So, solving

$= \frac{5-\sqrt{3}}{4+2\sqrt{3}}*\frac{4-2\sqrt{3}}{4-2\sqrt{3}} \\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{4+2\sqrt{3}*4-2\sqrt{3}}\\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{(4)^2-(2\sqrt{3})^2}\\= \frac{5(4-2\sqrt{3})-\sqrt{3}(4-2\sqrt{3})}{16-(4*3)}\\=\frac{20-10\sqrt{3}-4\sqrt{3}+2*3}{16-12}\\=\frac{20+6-14\sqrt{3}}{4}\\=\frac{26-14\sqrt{3}}{4}\\= \frac{2(13-7\sqrt{3})}{4}\\=\frac{13-7\sqrt{3}}{2}$

The triangle ABC goes through a series of transformations, resulting in the triangle A’B’C’. The three transformations are liste

Pie

Answer:

The new co-ordinates of A ( 2 ,-6)

Step-by-step explanation:

Type of transformation change to co-ordinate point

Vertical translation up 'd' units (x,y)→(x , y+d)

Vertical translation down 'd' units (x,y)→(x , y-d)

Horizontal translation right 'c' units (x,y)→(x+c , y)

Horizontal translation left 'c' units (x,y)→(x-c , y)

Reflection over x-axis (x,y) →(x , -y)

Reflection over y-axis (x,y) →(-x , y)

Given the original vertex A ( -2 ,3)

a) First reflection over x-axis ( -2 ,3) →(-2 , -3)

b) Vertical translation down '3' units so it changes (-2 , -3)→(-2 , -3-3)

(-2,-3)→(-2 ,-6)

and

c) The Horizontal translation right '4' units

now it changes ( -2 ,-6) → (-2+4,-6)→(2 ,-6)

Final answer:-

The new co-ordinates of A ( 2 ,-6)

Jacob is making spaghetti for the Anderson family reunion. He will use 14 boxes of spaghetti, with a total weight of 168 ounces.

Zigmanuir [339]

If your asking what the total weight would be. Take 168/14 and you get 12.
