How many revolutions does a go kart with a wheel circumference of 62.8318 inches make in a 1609 m race? Please answer as quickly
Rudiy27

Answer: 1008 revolutions

Step-by-step explanation:

1 revolution is equal to 2\pi r

To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel

You must first convert 62.8318 in to meters.

We know that 1 inch is 0.0254 meters

Then

62.8318\ in*\frac{0.0254\ m}{1\ in}= 1.5959\ m

revolutions = \frac{1609}{1.5959}\\\\revolutions=1008.21\\

Finally The wheel made 1008.21 revolutions

PLZ HELP,ANSWER WHAT IS IN THE PICTURE
MrMuchimi

Answer: X'(-3, -2), Y'(-5, 1), and Z'(2, -3)

Step-by-step explanation:

Upon reflection across the x-axis, the x-coordinates remain the same while the signs of the y-coordinates flip. So, the coordinates will be X(3, -2), Y(5, 1), and Z(-2, -3).

Upon reflection across the y-axis, the signs of the x-coordinates will flip while the signs of the y-coordinates remain the same. So, the coordinates will be X′(-3, -2), Y′(-5, 1), and Z′(2, -3).
