30 miles per hour
or, 30 miles per 60 minutes /:30
=> 1 mile per 2 minutes
50 miles => 2*50 minutes=100 minutes
100 minutes=60minutes+40minutes=An hour and 40 minutes
Given:
convex 41-gon
n = 41
Required:
Sum of interior angles.
Solution:
To solve for the sum of interior angles, we can use the formula:
Sum of interior angles = 180(n-2)°
Substituting,
Sum of interior angles = 180(41-2)°
Sum of interior angles = 7020°
Therefore, the sum of the measures of the interior angle of a convex 41-gon is 7020°.
Well, we need to divide $36.25 by 12.5. This will give us the per gallon price. So 36.25/12.5=2.90.
So regular gasoline is $2.90 a gallon
So, now we know this, if we add 14¢ to 2.90, we get $3.04. Now, we multiply 3.04 by 12.5=38. So, 12 and a half gallons of premium gas costs $38
