Answer:
Step-by-step explanation:
Solution :
It is given that :
Casey boarded a Ferry wheel at position of 3 'o' clock.
The angular speed of the Ferry wheel = 5.6 radians per minute
The radius of the Ferry wheel = 50 feet
The height of the center wheel of the Ferry from the ground = 55 feet
Let the number of minutes be = t
a). The expression of the varying number of radians θ is given by :
After t minutes, θ = angle swept
θ = 5.6 t radians
b). Finding the height from the center of the wheel.
We know that : y = r sin θ
Given r = 50 feet
So, y = 50 sin (5.6 t) feet
Therefore, the height above the ground can be found by :
h = y + 55 (from ground)
h = 50 sin (5.6 t) + 55 feet
Answer:
C) x = 9
Step-by-step explanation:
When two segments intersect in a circle like so, the product of the two parts of one segment will be equal to the product of the two parts of the other segment.
So,<em> 3 * 6 = x * 2</em>
Multiply: 18 = x * 2
Divide: x = 9
Answer:
22 fourth graders
Step-by-step explanation:
Set up an equation, with the total amount on one side and the amount per cone on the other. Let x represent the unknown number of students:
Now we need to solve for x. Do this by isolating it:
Undo the multiplication on the left side by dividing both sides by 1.47:
The 1.47 on the left now cancels each other out. Simplify:
x equals 22, so there are 22 fourth graders in the class.
:Done
