1/3 = 2/6
so 2/6 + 5/6 = 7/6 or 1 1/6
1 1/6 + 1 = 2 1/6

Well, you can turn 1/3 in to 2/6 and 1 and 2/6 plus 5/6 is 2 and 1/6.

Which is the correct calculation of the y-coordinate of point A? 0 (0 - 0)2 + (1 - y2 = 2 O (0 - 1)² + (0- y2 = 22 (0-0)² + (1 -

Answer:

The y-coordinate of point A is $\sqrt{3}$ .

Step-by-step explanation:

The equation of the circle is represented by the following expression:

$(x-h)^{2}+(y-k)^{2} = r^{2}$ (1)

Where:

$x$ - Independent variable.

$y$ - Dependent variable.

$h$ , $k$ - Coordinates of the center of the circle.

$r$ - Radius of the circle.

If we know that $h = 0$ , $k = 0$ and $r = 2$ , then the equation of the circle is:

$x^{2} + y^{2} = 4$ (1b)

Then, we clear $y$ within (1b):

$y^{2} = 4 - x^{2}$

$y = \pm \sqrt{4-x^{2}}$ (2)

If we know that $x = 1$ , then the y-coordinate of point A is:

$y = \sqrt{4-1^{2}}$

$y = \sqrt{3}$

The y-coordinate of point A is $\sqrt{3}$ .

Can someone help me with number 135?

Nat2105 [25]

so from accidental deaths we have

30 from falls

47 from fires

200 from drowning

1950 car accidents

so the total of those is 30+47+200+1950, or 2227.

the ones that weren't car accidents will be 2227 - 1950, or 277.

if we take 2227 to be the 100%, how much is 277 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 2227&100\\ 277&x \end{array}\implies \cfrac{2227}{277}=\cfrac{100}{x}\implies x=\cfrac{277\cdot 100}{2227} \\\\\\ x\approx 12.4382577~\hspace{7em}\stackrel{rounded~up}{x=12}$

Doreen has $20. She wants to buy a pair of earrings that costs $7.58 and a necklace that costs &13.36. Does Doreen have enou

Mariana [72]

Hi!

To solve this, we need to know how much the earrings and necklace cost together, then we need to know if it's more or less than how much she has ($20)

So first, add the costs together.

7 . 5 8
+ 1 3 . 3 6
---------------
2 0 . 9 4

The necklace and earrings cost $20.94 which is more than $20.

The answer is no, Doreen does not have enough money.

Hope this helps! :)

Please help! Correct answer only, please! Consider the matrix shown below: Find the inverse of the matrix A: (i.e Find A^-1).

Step2247 [10]

Answer:

Hello There Again. The correct answer is D.

Explanation: Why is D. Because 5x2=10 which everyone know that 5x2=10x3x1=30 So the best choice will be D.

Hope It Helps!
