Answer:

0.755 Yuan

Step-by-step explanation:

You already know it's going to be less than 1 since 1 yuan is 13.2455 yen.

Chinese Yaun : Japanese Yen

1 : 13.2455

divide both by 13.2455 to work out 1 Japanese Yen

0.0755 : 1

Multiply both 10

0.755: 10

Solve the quadratic equation by square roots: 1. 4x²= 81 2. (4x-3)²+7=39

Nataly [62]

Answer:

see explanation

Step-by-step explanation:

(1)

given

4x² = 81 ( divide both sides by 4 )

x² = $\frac{81}{4}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{81}{4} }$ = ± $\frac{9}{2}$

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

(2)

subtract 7 from both sides

(4x - 3)² = 32 ( take the square root of both sides )

4x - 3 = ± $\sqrt{32}$ = ± 4 $\sqrt{2}$

Add 3 to both sides

4x = 3 ± 4 $\sqrt{2}$ ( divide both sides by 4 )

x = $\frac{3}{4}$ ± $\sqrt{2}$

Perform the following calculations without rewriting the numbers in decimal form.

RSB [31]

Answer:

Answer will be $140\times 10^{13}$

Step-by-step explanation:

We have to perform the calculation $(1.42\times 10^{15}-2\times 10^{13})$ without changing into decimal

$1.42\times 10^{15}$ can be written as $142\times 10^{13}$

So $1.42\times 10^{15}-2\times 10^{13}=(142\times 10^{13}-2\times 10^{13})$

Now taking $10^{13}$ common

$10^{13}(142-23)=140\times 10^{13}$

HELP PLEASE !!!!!!! Pythagorean theorem

Phoenix [80]

Answer:

$\large\boxed{x=8\sqrt3}$

Step-by-step explanation:

The Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have:

$leg=8, leg=x,\ hypotenuse=16$

Substitute:

$8^2+x^2=16^2$

$64+x^2=256$ subtract 64 from both sides

$x^2=192\to x=\sqrt{192}\\\\x=\sqrt{(64)(3)}\\\\x=\sqrt{64}\cdot\sqrt3\\\\x=8\sqrt3$
