Answer:
7hours and 30 minutes
Step-by-step explanation:
given a car travels with a speed of 50 miles -------->1hour
x miles -------->6hours
on cross multiplying we get the value of 'x'
x = 50×6 = 300
x=300miles
Now ,
40mls------->1h
300mls------->xh
x= 300/40
x=(3/4)×10
x= 7.5hours
x= 7½hours
The volume of a rectangular prism is given by the multiplication of its three dimensions: if
are the width, height and length of the prism, the volume is

So, in your case, you have

Given:


To find:
The value of
.
Solution:
We have,


Using properties of log, we get
![\left[\because \log_a\dfrac{m}{n}=\log_am-\log_an\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbecause%20%5Clog_a%5Cdfrac%7Bm%7D%7Bn%7D%3D%5Clog_am-%5Clog_an%5Cright%5D)
![[\log x^n=n\log x]](https://tex.z-dn.net/?f=%5B%5Clog%20x%5En%3Dn%5Clog%20x%5D)
Substitute
and
.



Therefore, the value of
is
.
