Mathematics
1 answer:
makvit [3.9K]2 years ago
4 0

Step-by-step explanation:

Using the properties of logarithms, the left side of the equation becomes

\log{3x^3} - \log{x^2} = \log{3x}

while the right hand side becomes

\log{27} - \log{x} = \log{\frac{27}{x}}

so we end up with

3x^2 =27 \Rightarrow  x = 3

True or false ? A car taking a turn at a constant speed is accelerating.
erastovalidia [21]
True. The velocity is changing because the direction is changing. Velocity is the combination of speed and direction. The change in velocity leads to a change in acceleration.

A shopkeeper fixed the marked price of his radio to make a profit of 30 %. Allowing 15 % discount on the marked price, the radio
topjm [15]

Answer:

10.5 %

Step-by-step explanation:

Here .

let the Cost Price be 'x'

the..

by the question..

the marked price was fixed to make 30% profit

then..

the marked price will be

x+ 30% of x

= x + 30/100 × x

=x+ 0.3x

=1.3x

soo .. the marked price is 1.3x

now.. after allowing 15% discount..

the selling price will be

1.3x - 15% of 1.3x

= 1.3x - 0.195x

= 1.105x

thank you...

plzz mark me brainliest now

now..

profit made = 1.105x-x

= 0.105x

soo .

in percentage..

profit percent = profit/cp × 100%

= 0.105x/x × 100%

= 10.5 %
