Answer:
8xyz
Step-by-step explanation:
multiply all numbers and alphabets
- 288xyz, 2.360xyz, 3.648xyz
- find HCF of numbers and after multiply by xyz
- 288={2×2×2×31}
- 360={2×2×2×3×3×5}
- 648={2×2×2×3×3×3×3}
- HCF={2×2×2}xyz
- 8xyz
Yes because 11 is x and y together and the others are 11xy too
Answer:
227.75 cm
Step-by-step explanation:
a coin (Circle) with diameter 2.9cm
(radius) r = diameter ÷ 2
r = 2.9cm ÷ 2
r = 1.45cm
1 complete revolutions (perimeter or circumference of a circle ) = 2πr
= 2 × π × r
where r = radius, π is a constant = 22/7
= 2 × 22/7 × 1.45
= 9.11cm
thus in one complete revolution the coin travels a distance of 9.11cm.
therefore in 25 complete revolutions the coin will travel a distance of = 25 × 9.11 cm = 227.75 cm.
The distance covered in complete 25 revolutions of a coin with diameter of 2.9 when it's rolled is = 227.75 cm
2/5 = 20/50 = 40/100 = 40%
