A city is 7,642 feet above sea level. Is this elevation closer to the highest point or the lowest point?
tekilochka [14]

Answer:

It must be closer to the lowest point.

Step-by-step explanation:

There is a simple and a general explanation to it. As it gets higher up from the sea level, the elevation gets closer to the lowest point simply because the distance from the highest point keeps decreasing as you get closer. The elevation is the distance left between the highest point and the current point.

I need help please i​
balandron [24]

Answer:

<em>2 7/24</em>

Step-by-step explanation:

<em>First we have to add the gallons of two cow of each owner:</em>

<em>Hank's cows: </em><em>4 3/4 + 4 1/8</em>

<em>Add the whole numbers:</em>

<em>4 + 4 = 8</em>

<em>Now for 3/4 and 1/8 </em>

<em>Find common</em>

<em>6/8 + 1/8</em>

<em>= 7/8</em>

<em>Put together :</em>

<em>8 7/8</em>

<em>Debra's cows: </em><em>5 1/2 + 5 2/3</em>

<em>Add the whole number</em>

<em>5 + 5 = 10</em>

<em>Now for 1/2 and 2/3</em>

<em>3/6 + 4/6</em>

<em>1 1/6</em>

<em>10 + 1 1/6 </em>

<em>= 11 1/6</em>

<u><em>Since now we know that:</em></u>

<u><em>Hank - </em></u><em>8 7/8</em>

<u><em>Debra - </em></u><em>11 1/6</em>

<em>we can solve the question:</em>

<em>How many more gallons of milk did Debra's two cows produce on that compared to Hank's two cows?</em>

<em>Solution:</em>

<em>11 1/6 - 8 7/8</em>

<em>Subtract whole number</em>

<em>11 - 8 = 3</em>

<em>Now for 1/6 and 7/8</em>

<em>4/24 - 21/24</em>

<em>4-21/24</em>

<em>-17/24</em>

<em>2 7/24</em>
