The landmass of earth is approximately 5 × 10^7 square miles. glaciers take up an area of approximately 5 × 10^6 square miles. about what fraction of the earth’s total land area is taken up by glaciers? show work!

of the Earth’s total land area is taken up by glaciers.

Step-by-step explanation:

1. To solve this problem you must divide the area taken up by glaciers by the area of the landmass of Earth.

2. You know that the aproximated area of the landmass of Earth is miles² and the area taken up by glaciers is approximately miles², therefore, you have:

3. Therefore, the fraction of the Earth’s total land area that is taken up by glaciers is: .

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
