The troposphere extends from the earth’s surface to a height of 6-12 miles depending on the location and the season. if a plane is flying at an altitude of 5.8 miles and the troposphere is 8.6 miles deep in that area how much higher can the plane go without leaving the troposphere

The plane can go 2.8 miles higher without leaving troposphere.

Step-by-step explanation:

Troposphere extends from the earth's surface to a height of 6 - 12 miles which varies on different locations.

If a plane is flying at an altitude of 5.8 miles.

The altitude of the troposphere is 8.6 miles deep from that location.

Therefore, the plane can go more up without leaving the troposphere = 8.6 - 5.8 = 2.8 miles

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
