Hi,
Because the angles are equal (38) and both are right triangles, it is assumed that 3x=12. Now you simply divide and get 4.
Answer:
look at explanation
Step-by-step explanation:
To solve all of these questions you just need to scale. While scaling you can divide or multiply.
1. (divide by 4 to get unit rate)
unit rate =
2. If it takes one hour to travel 40 miles, then we don't have to scale or anything. We know , the answer is...
"It'll only take one hour to travel 40 miles. This is correct because the unit rate is . "
3. Knowing that the constant speed of the plane is , we can scale then add half of the unit rate to get our answer.
x 3 = 800 x 3 = 2400
then add half of unit rate which is = 400
so, our answer is
4. <--- ( divided by 2) ( multiplied x 2.5) --->
To get an easier way to find the answer, if possible you can scale back farther than the 1 hour mark.
Elmer would take 2 and a half hours to ride 15 km.
5. The boys speed is . All we need to do is divide by 2. = 4
Answer: The correct answer is Choice C.
The fourth quartile is the last section of the graph. It goes from the right edge of the box to the last point on the graph.
The last point is 45 and the right edge of the box is 38.
Subtracting these values will give the range of the 4th quartile.
45 - 38 = 7
