Ojos del salado is the highest mountain in chile, with a peak at about 6900 meters above sea level. the atacama trench, just off the coast of peru and chile, is about 8100 meters below sea level (at its lowest point). what elevation is halfway between the peak of mount ojos del salado and the atacama trench?

Let

y1---------> is the high of the mountain Ojos del Salado in meters, above sea level

y2---------> is the deep of the Trench in meters below sea level

we know that

so

Find the halfway elevation

calculate the distance

substitute the values

Find the midpoint

=15,000/2=7,500\ m

The midpoint is located below the sea level

so

therefore

the answer is

The halfway elevation is about below sea level

d

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
