Price of gallon of gasoline one year ago is $ 4.1
<em><u>Solution:</u></em>
Given that you pay $ 3.69 for a gallon of gasoline
This is 90% of the price of a gallon of gasoline one year ago
To find: price of a gallon of gasoline one year ago
We can solve this sum by setting up proportion
Let "x" be the price of gallon of gasoline once year ago
By proportions we get,
Thus price of gallon of gasoline one year ago is $ 4.1
Method 2:
you pay $ 3.69 for a gallon of gasoline
Let "x" be the price of gallon of gasoline once year ago
3.69 = 90% of the price of a gallon of gasoline one year ago
3.69 = 90 % of x
Thus price of gallon of gasoline one year ago is $ 4.1
Answer:
There is no question??
Step-by-step explanation:
Step-by-step explanation:
Consider the provided information.
A convex polygon is a polygon with all its interior angles less than 180°.
Regular polygon is a polygon in which all angles are equal and all sides are the same length.
An irregular polygon does not have congruent sides and interior angles.
From the above definitions we can identify the similarities and differences between the interior and exterior angles of both polygons.
Difference:
The interior angles of regular polygon are equal.
Since, the interior angles of a regular polygon are equal, the exterior angles must also be equal to one another.
The interior angle of irregular polygons are not equal, however, each exterior angle may have a different measurement as well.
Similarity:
The sum of interior angles for both polygon are equal. Also the sum of exterior angles for both polygon are equal.
Set up equations like this (keep in mind that perimeter of a rectangle is all sides added up, so two lengths and two widths):
2l + 2w = 340
l = w + 10
Plug (w + 10) in for l in the first equation and solve for w:
2(w + 10) + 2w = 340
2w + 20 + 2w = 340
4w + 20 = 340
4w = 320
w = 80
The width of the field is 80 yd. Plug 80 in for w in either equation:
l = 80 + 10
l = 90
The length of the field is 90 yd.
