Herman is traveling 125 miles from his house to the beach by car. Herman plans to stop for lunch when the ratio of the distance

Answer:

250 miles

Step-by-step explanation:

The given distance between the house and the beach is 125 miles.

Let $x$ miles be the distance between the house and the lunch stop.

So, at the time of the lunch stop, he already traveled $x$ miles, the remaining distance is the distance between the lunch stop and the beach.

Let $y$ miles be the remaining distance, so

$y=125-x.$

Give that the ratio of the distance he has traveled, $x$ , to the distance he still has to travel, $y$ , is $2:3$ ,i.e

$x:y=2:3$

$\Rightarrow \frac x y =\frac 2 3$

$\Rightarrow \frac {x}{125-x}=\frac 2 3$

$\Rightarrow 3\times x=2\times(125-x)$

$\Rightarrow 3\times x=2\times125-2\timesx$

$\Rightarrow 3 x=250-2x$

$\Rightarrow 3x-2x=250$

$\Rightarrow x=250$

Hence, the distance traveled by Herman when he stops for lunch is 250 miles.

Answer:

The area is 522.935 square inches.

Step-by-step explanation:

A trapezoid's area is calculated as follows: h(b1+b2)/2

Plugging numbers in gives 34.3+12.6=46.9

so now all that's left is to multiply 22.3 and 46.9, and divide by 2.

This gives 522.935

Hope this helps!
