A solid yellow stripe is to be painted in the middle of a certain highway. If 1 gallon of paint covers an area of p square feet
Zolol [24]

Answer:

440mt/p gallons

Explanation:

We are told that one gallon of paint covers an area of p square feet. Knowing this then, the question becomes how much paint is needed to cover a stripe that is t inches wide and m miles long.

Let us first use the dimensions of the stripe to find how much area that is in square feet. A stripe is rectangular so we will calculate the area as follows:

Area of stripe = width x length

                       = t inches x m miles              (we need to convert both to feet)

                       = (t inches x 1 ft/12 inches) x (m miles x 5280 ft/1 mi)

                       =440mt square feet

ow we can find out how much paint will be needed by using ratios

p square feet : 1 gallon

440mt square feet : x

x = 440mt/p gallons

What factors play a role in the rate at which molecules like O₂ and CO₂ can diffuse?
nadezda [96]

Answer:

The correct answer is b the magnitude of the concentration gradient of the molecule.

Explanation:

Dffusion is one of most important membrane transport process that allow several molecules such as gases oxygen and carbon dioxide to pass directly across the plasma membrane.The is no involvement of  carrier proteins or ion channels during passive diffusion.

    During passive diffusion molecules are transported along their concentration gradient that means from the region of high concentration to region of low concentration,until the concentration of both regions become same.
