You need to find out if 57 can be divided evenly by a number other than 1 and 57.
57 is odd, so it is not divisible by 2.
The digits of 57 are 5 and 7. Add 5 + 7 to get 12. Since 12 is divisible by 3 (12/3 = 4), then 57 is also divisible by 3.
57/3 = 19
19 is a prime number, so the only factors of 57 are 1, 3, 19, 57.
57 rows can be divided into 19 sections of 3 rows each or 3 sections of 19 rows each.
Answer:
7:3
Step-by-step explanation:
Sum of all exterior angles = 360°.
Number of sides = 360 ÷ 40 = 9
Each interior angle = 180 - 40 = 140°.
Answer: <span>The regular polygon has 9 sides and each of its interior angles 140°</span>
Answer: √7 feet
Step-by-step explanation:
Hypotenuse(h)=4ft
Base(b)=3ft
Now,Using pyhagoras theorem,
h²=p²+b²
4²=p²+3²
16-9=p²
p=√7feet
Hence, the remaining side is √7feet
42.5x/100 = 20.57
42.5x = 20.57*100
42.5x = 2057
x = 2057/42.5
x = 48.4
