Solve the math problem

Marianna [84]

Answer:

<1 = 109 (Vertically Opposite to <3)

<2 = 71 (Corresponding to <6)

<3 = 109

<4 = 71 (Alternate Interior to <6)

<5 = 109 (Alternate Interior to <3)

<6 = 71

<7 = 109 (Corresponding to <3)

<8 = 71 (Vertically Opposite to <6)

Step-by-step explanation:

<1 = 2x + 29

<2 = x + 31

<3 = 2x + 29

<4 = x + 31

<5 = 2x + 29

<6 = x + 31

<7 = 2x + 29

<8 = x + 31

<1 + <2 = 180

(2x + 29) + (x + 31) = 180

(2x +x) + (29 + 31) = 180

3x + 60 = 180

3x = 180 - 60 = 120

x = 120/3

x = 40

<1 = (2x + 29)

= (2 * 40) + 29

= 80 + 29

= 109

<2 = x + 31

= 40 +31

= 71

Rationalize the denominator of $\frac{\sqrt{32}}{\sqrt{16}-\sqrt{2}}$. The answer can be written as $\frac{A\sqrt{B}+C}{D}$, whe

musickatia [10]

Rationalizing the denominator involves exploiting the well-known difference of squares formula,

$a^2-b^2=(a-b)(a+b)$

We have

$(\sqrt{16}-\sqrt2)(\sqrt{16}+\sqrt2)=(\sqrt{16})^2-(\sqrt2)^2=16-2=14$

so that

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{\sqrt{32}(\sqrt{16}+\sqrt2)}{14}$

Rewrite 16 and 32 as powers of 2, then simplify:

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{\sqrt{2^5}(\sqrt{2^4}+\sqrt2)}{14}$

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{2^2\sqrt2(2^2+\sqrt2)}{14}$

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{4\sqrt2(4+\sqrt2)}{14}$

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{16\sqrt2+4(\sqrt2)^2}{14}$

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{16\sqrt2+8}{14}$

$\dfrac{\sqrt{32}}{\sqrt{16}-\sqrt2}=\dfrac{8\sqrt2+4}7$

So we have A = 8, B = 2, C = 4, and D = 7, and thus A + B + C + D = 21.

$ 570 2% 4years simple interest

denis-greek [22]

For simple interest, just multiply all of them together

note that 2% = 0.02

570(0.02)(4) = 45.6

simple interest is 45.6

oh and if you need the equation, it is p(r)t, or principle x rate x time

hope this helps

Can you help me with this question plzz?

Dominik [7]

Answer: The answer is 96 wizards.

Step-by-step explanation:

So what I like to do is fraction formatting.

you start with x/blank $\frac{blank}{120}$ and $\frac{80}{100}$ you do cross multiply divide

and multiple 120 by 80(=9600) and divide by 100 (=96) because wizards are 20% less of the population than goblins, so they are equivalent to 80% of the goblins! Hope this helped!
