Answer:
0.5
Step-by-step explanation:
The decimal 0.25 represents the fraction 25/100. Decimal fractions always have a denominator based on a power of 10. We know that 5/10 is equivalent to 1/2 since 1/2 times 5/5 is 5/10. Therefore, the decimal 0.5 is equivalent to 1/2 or 2/4, etc.
You can do $42.25 divided by 6.5 = x or x times 6.5 = $42.25
Answer:
30° and 12
Step-by-step explanation:
The sum of the exterior angle and the interior angle = 180°
sum the parts of the ratio, 1 + 5 = 6 parts
Divide 180° by 6 to find the value of one part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio
(i)
The exterior angle = 30°
(ii)
The sum of the exterior angles of a polygon is 360°
To find the number of sides n divide 360 by 30 , that is
n = 360 ÷ 30 = 12
