Wouldn't the ratio from length to width be 8?
The number of rotations for the new wheel will be 1,056 rotations
<h3>How to calculate the circumference of a wheel?</h3>
Let the initial circumference be 50 rotations (assumed)
If the number of rotations of the circumference of the tires were increased by 20%, then the new circumference will be:
Ne circumference = 1.2 * 50 = 60
number of rotations for the new wheel = 63360/60
number of rotations for the new wheel = 1,056 rotations
Hence the number of rotations for the new wheel will be 1,056 rotations

Answer:
£592 for 16 boxes
Step-by-step explanation:
The classroom floor area is ...
A = LW = (8.8 m)(2.2 m) = 19.36 m²
The cupboard floor area is ...
A = (2.3 m)(2.1 m) = 4.83 m²
Then the total area to be covered is ...
19.36 m² +4.83 m² = 24.19 m²
At 1.6 m² per box, the number of boxes required is ...
(24.19 m²)/(1.6 m²/box) = 15.12 boxes
If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...
(16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor
Complementary angles add up to 90 degrees.
The complement of 57 is (90 - 57) = 33 degrees.
(x - 4)² = 25
x - 4 =
√25
x - 4 =
5
x = 5 + 4 or x = -5 + 4
x = 9 or x = -1
Method Use : Completing the square-------------------------------
Answer: x = 9 or x = -1-------------------------------
