If the product of the extremes is 8,then the geometric mean is

Jlenok [28]

The geometric mean of two numbers is the square root of their product:

$GM(a,b)=\sqrt{ab}$

So, if the product is 8, the geometric mean is $\sqrt{8}=2\sqrt{2}$

Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the o

uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

$Speed=\frac{distance}{time}$

in this problem

$Speed=\frac{y}{x}$

$y=(Speed)*x$

Equation First Train

$y1=70x$

Equation Second Train

$y2=80x$

$y1+y2=600\ miles$ ---------> equation $1$

Substitute the values of $y1$ and $y2$ in the equation $1$

$70x+80x=600$

Solve for x

$150x=600$

$x=4\ hours$

therefore

the answer is

$4\ hours$

At a bus station, buses begin their routes at 6 a.M. The schedule for two of the buses is based on the time intervals listed bel

Marianna [84]

Answer:

The next time both will leave the bus station at the same time is 7:15 a.m.

Step-by-step explanation:

Since 15 and 75 are multiples to each other.

So, L.C.M. of 15 and 75 is 75.

So, after 75 minutes both buses will leave the station at the same time.

Also since buses begin their routes at 6 a.m.

So, next time they will meet at

6 hours 0 minutes + 75 minutes = 7 hours 15 minutes = 7:15 a.m.
