The tires of a go-cart are 1 m in circumference. The tires revolve 15 times per second. What is the distance the go-cart travels in 40 seconds? Put your answer in meters.

Answers

Answer:

600 m

Step-by-step explanation:

The circumference of a tire is the distance around it.  The distance around these tires is 1 m.  

Since the tires revolve 15 times per second, this means every second the tires travel 15 m.

This means that in 40 seconds, the tires travel

15(40) = 600 m.

Step-by-step explanation:

B)

  1) Simplify the ratio of 3:6 to 1:2

  2) In order to see how many raisins are needed, multiply both sides by the amount that are needed to get four ounces of nuts (which is 2, as 2 x 2 = 4).

  3) Thus, you multiply the amount of ounces of raisins as well, so 1 x 2 = 2

C)

  1) Simplify the ratio of 3:6 to 1:2

  2) In order to see how many raisins are needed, multiply both sides by the amount that are needed to get four ounces of nuts (which is 8, as 2 x 8 = 16).

  3) Thus, you multiply the amount of ounces of raisins as well, so 1 x 8 = 8

does y-intercept and the x-intercept be the same point on a graph/

Answers

Step-by-step explanation:

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Answer:

This question doesn't really make sense, but if you are asking if the x and y-intercept can be the same point on a graph, yes: (0,0).

Step-by-step explanation:

- The y-intercept is the point where the line crosses the y-axis, and the x-intercept is the point where the line crosses the x-axis.

- For example, a coordinate that comes to mind that is both the y and x-intercept is the graph y=x (0,0).
