Which fraction represents the decimal 0.8888...?
suter [353]

Answer: The decimal 0.88888.... represented by the fraction \dfrac{8}{9}

Step-by-step explanation:

Since we have given that

0.888888....

So, Let x = 0.88888....=0.\bar{8} -----(1)

Now, multiply by 10 on both sides, we get that

10x=8.8888.....=8.\bar{8}----------(2)

Now, Subtracting (1) from (2), we get that

10x-x=8.\bar{8}-0.\bar{8}\\\\9x=8\\\\x=\dfrac{8}{9}

Hence, the decimal 0.88888.... represented by the fraction \dfrac{8}{9}

17. Consider the function f(x, y, z) = xy ln(yz).
Lelu [443]

We can expand

f(x,y,z) = xy\ln(yz) = xy \ln(y) + xy\ln(z)

Then using the product and chain rules,

\dfrac{\partial f}{\partial x} = y\ln(y) + y\ln(z) + \boxed{y\ln(yz)}

\dfrac{\partial f}{\partial y} = x\ln(y) + \dfrac{xy}y + x\ln(z) = \boxed{x\ln(yz) + x}

\dfrac{\partial f}{\partial z} = \boxed{\dfrac{xy}z}

The sum of the areas of two circles is 80n square meters. Find the length of a radius of each circle if
astra-53 [7]

Answer:

8 meters.

Step-by-step explanation:

Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π

π x^2 + π 4x^2= 80π

x^2 + 4x^2= 80

5x^2 = 80

x^2 = 16

x = 4.

So the radius of the larger circle = 2*4 = 8 m.
