Answer:
The wheel will make 40 revolutions.
Step-by-step explanation:
We are given;
Diameter = 77 cm = 0.77m
Radius = 0.77/2
Radius = 0.385 m
Speed = 1.1 m/s
time = 1min 28 sec = 88 sec
Now, we know that;
Distance = speed×time
Thus;
Distance = 1.1 × 88
Distance = 96.8 m
Also,
Number of revolution = distance/circumference
Number of revolutions = 96.8/(2 × π × 0.385)
Number of revolutions ≈ 40
Answer: - 6 1/2
Step-by-step explanation:
We should note that:
=-4 - 2 1/2
= -6 1/2
For example, let's assume you owe Bob $4 and then you owe Bill $2 1/2. To calculate the total amount owed, you would have $6 1/2.
Answer:
Step-by-step explanation:
1_| 1 -2 -5 6
<u> 1 -1 -6</u>
1 -1 -6 0
Q(x)= x^2 - x - 6
R: 0
A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is <em>x</em>, then the diagonal is such that
√(2) <em>x</em> = 10 cm
→ <em>x</em> = 10/√(2) cm ≈ 7.07 cm
The perimeter of a square is 4 times its side length, so the perimeter is
4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm
which makes 28.4 cm the closest answer.
