Answer:
<h2>Sam cycled fast, at a rate of 10 miles per hour.</h2>Step-by-step explanation:
To solve this problem we have to find the slope of each case. The definition of a slope is:
Where is the first point, and
is the second point.
Let's find each slope.
<h3>Sam.</h3>Let's use the points and
Applying the definition of the slope, we have:
This relation means that Sam cycled 10 miles per hour.
<h3>Bobby.</h3>Let's use the points and
Bobby cycled 9 miles per hour.
Therefore, according to these ratios, Sam cycled fast, at a rate of 10 miles per hour.
Answer:
C. Claire has 10 country CDs and 5 Jazz CDs
Step-by-step explanation:
means that 10 out of 15. So we can assume that in total she has 15 CDs and 10 of them are Country and the other is Jazz.
This would rule out choice D.
If we reduce this fraction then we would have:
This means that two-thirds of her CDs are country music. So this would rule out A and B choices.
Now C is correct because 10 country plus 5 Jazz is equal to 15 CDs. So we have the correct total.
The answer is C.
