Answers:
25c= 1/2
Then R3.50 is 3/50
Step-by-step explanations:
25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2
For this you have to first find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.
3 ÷ 150 ÷ 1.
Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.
Since you are rounding to the nearest whole number, look at the digit in the tenth place. If it is 5 and greater, round up, if it is 4 and lower, round down
25.311 = 25
4.65 = 5
25 x 5 = 125
125 is your answer

Answer:
Exterior angle of a decagon will be 36°
Step-by-step explanation:
Measure of all interior angles of a polygon is represented by (n - 2)×180°
where n is the number of sides of the polygon.
Now we have to calculate the exterior angle of a regular decagon.
As we know exterior angle of polygon is supplementary of the interior angle.
So we will calculate interior angle first.
Sum of interior angles of decagon = (n - 2)×180° = 8×180° = 1440°
Since decagon is regular so all angles will be same.
So one angle of decagon = 1440 ÷ 10 = 144°
Now exterior angle = 180 - 144 = 36°
Each exterior angle of a decagon will be 36°.
