At a gas station, it takes 14 seconds to pump 2 gallons of gas. if the amount of gasoline pumped varies directly with time, how
EleoNora [17]

Answer:

See below:

Step-by-step explanation:

If we do this, we know that 2 gallons takes 14 seconds. (2:14)

Based on that data, we can know that 1 gallon takes 7 seconds. (1:7)

-> 2/14 = 1/7

Now we can multiply by 12 to get 12 gallons on one side.

What we do on one side has to happen to the other side.

So, 12 gallons * 1 gallons = 12 gallons and 12 gallons * 7 gallons = 84 gallons.

So the final answer is 85 gallons,

A circular garden with a radius of 20 meters is surrounded by a walkway that measures 1 meter in width. -1 m 20 m Find the area
juin [17]
<h3>Answer:  128.74  square meters</h3>

=========================================================

Explanation:

The area of the garden only (ignore the circular pathway) is approximately

A = pi*r^2

A = 3.14*20^2

A = 1256

The area of the garden plus the path is approximately

A = pi*r^2

A = 3.14*21^2

A = 1384.74

Notie how I added on 1 meter to increase the radius to 21

Subtract the two circle areas to get the area of the circular ring.

1384.74 - 1256 = 128.74

The units for all of the areas mentioned are "square meters".
