This also 7th fgrade homework!!
harkovskaia [24]

Answer:

Down the left-hand column, the pattern is counting by 5's. Therefore, 5, 10, 15, 20, 25. Down the right-hand column, the pattern is counting by 4's. Therefore, 4, 8, 12, 16, 20. Thus, the ratios are:

5:4

10:8

15:12

20:16

25:20

In other words, the first line (5:4) is the base ratio. The second line multiplies the original values by 2, the third line by 3, the fourth line by 4, and the fifth line by 5.

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
Likurg_2 [28]

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.
