Answer:

Step-by-step explanation:

So if you know that 10 skeins makes 4 scarves... then 20 skeins makes 8 scarves (because you doubled it)

and if 10 skeins make 4 scarves... then half that number of skeins should make half the number of scarves... so 5 skeins makes 2 scarves

So we know that 20 skeins makes 8 scarves and 5 skeins make 2 scarves... all we have to do is add up the skeins and find we get 10 scarves

1 yard in 6 minutes

Question 1
Part A

Find the unit rate.

Answers

The unit rate is 1 yard :: 6 minutes. This is correct because you cannot divide each number evenly.

The unit rate in feet per second is 1/120 feet/sec.

Given that, 1 yard in 6 minutes.

What is the unit rate?

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

We know that 1 yard=3 feet and 1 minute = 60 seconds

Now, 6 minutes = 360

So, unit rate is 3/360

= 1/120 feet/sec

Therefore, the unit rate in feet per second is 1/120 feet/sec.
