A square picture with side length 30 cm is scaled by 60% on a photocopier the copy is then scaled by 60% again. What is the side

Sonja [21]

Answer:

10.8 cm

Step-by-step explanation:

we know that

1) A square picture with side length 30 cm is scaled by 60% on a photocopier

Remember that

$60\%=60/100=0.60$

The length of the first copy of the picture is

$30(0.60)=18\ cm$

2) The copy is then scaled by 60% again

The length of the second copy of the picture is

$18(0.60)=10.8\ cm$

The value of Y and Z

igor_vitrenko [27]

What I think you should do is that you multiply 99 and 82 degrees and divide that answer with 110 and you get z. Than for y is 99.

I don't know if it's right but that I think you should do.

Condense the following logs into a single log:

mamaluj [8]

QUESTION 1

The given logarithm is

$8\log_g(x)+5\log_g(y)$

We apply the power rule of logarithms; $n\log_a(m)=\log_(m^n)$

$=\log_g(x^8)+\log_g(y^5)$

We now apply the product rule of logarithm;

$\log_a(m)+\log_a(n)=\log_a(mn)$

$=\log_g(x^8y^5)$

QUESTION 2

The given logarithm is

$8\log_5(x)+\frac{3}{4}\log_5(y)-5\log_5(z)$

We apply the power rule of logarithm to get;

$=\log_5(x^8)+\log_5(y^{\frac{3}{4}})-\log_5(z^5)$

We apply the product to obtain;

$=\log_5(x^8\times y^{\frac{3}{4}})-\log_5(z^5)$

We apply the quotient rule; $\log_a(m)-\log_a(n)=\log_a(\frac{m}{n} )$

$=\log_5(\frac{x^8\times y^{\frac{3}{4}}}{z^5})$

$=\log_5(\frac{x^8 \sqrt[4]{y^3} }{z^5})$
