Barry Road his scooter<br> for 24 minutes at a speed of 0.5 per minute how far did he go
liraira [26]
Well, I'm not sure what units "0.5" apply to, but to find the distance he rode, you will need to multiply.

0.5 * 24 = 12.

Barry rode his scooter for a distance of 12 [insert units here].

Hope this helps! Have a great day :)

A Ferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. If the Ferris wheel makes one comp
Morgarella [4.7K]

Answer:

y = 11 - 10cos(0.1\pi t)

Step-by-step explanation:

Suppose at t = 0 the person is 1m above the ground and going up

Knowing that the wheel completes 1 revolution every 20s and 1 revolution = 2π rad in angle, we can calculate the angular speed

2π / 20 = 0.1π rad/s

The height above ground would be the sum of the vertical distance from the ground to the bottom of the wheel and the vertical distance from the bottom of the wheel to the person, which is the wheel radius subtracted by the vertical distance of the person to the center of the wheel.

y = h_g + d_b = h_g + R - d_c (1)

where h_g = 1 is vertical distance from the ground to the bottom of the wheel, d_b is the vertical distance from the bottom of the wheel to the person, R = 10 is the wheel radius, d_c is the vertical distance of the person to the center of the wheel.

So solve for d_c in term of t, we just need to find the cosine of angle θ it has swept after time t and multiply it with R

d_c = Rcos(\theta(t)) = Rcos(\omega t) = 10cos(0.1\pi t)

Note that d_c is negative when angle θ gets between π/2 (90 degrees) and 3π/2 (270 degrees) but that is expected since it would mean adding the vertical distance to the wheel radius.

Therefore, if we plug this into equation (1) then

y = h_g + R - d_c = 1 + 10 - 10cos(0.1\pi t) = 11 - 10cos(0.1\pi t)

If I have 10 dollars and I win 6 out of 10 and lose 4 out of 10 and bet 1$ each trade, how much should there be left after 10 tr
ololo11 [35]

you will be left with 12 dollars.

<u> </u><u>Step-by-step explanation: </u>

Given:

The actual money you have = 10 dollars.

The bet amount for each trade= 1$

For each win, you get extra +1 dollar.

Step 1:

So, you won 6 trades= (6*1)= 6$

Step 2:

For each lose, you loss -1 dollar.

Step 3:

So, you lose 4 trades= (4)*(-1)= -4$

Step 4:

After 10 trades, the money you earned is= 6$ -4$= 2 dollars.

Finally, the total money left after 10 trades is= actual money + earned money                                                

= $10 + $2= 12 dollars.
