Ashby ate a lot for Thanksgiving dinner. He decided to go on a long run. He ran 6 miles in 57 minutes. How long did it take him
2 answers:
Answer : It take him to run one mile is, 9.5 minutes.
Step-by-step explanation :
As we are given that Ashby ran 6 miles in 57 minutes. Now we have to determine the time taken by him to run one mile.
As, he take time to run 6 miles distance = 57 minutes
So, he take time to run 1 miles distance =
= 9.5 minutes
Therefore, it take him to run one mile is, 9.5 minutes.

Answer:
<h3>- The ratio of the measure of central angle PQR to the measure of the entire circle is One-eighth. </h3><h3>- The area of the shaded sector depends on the length of the radius. </h3><h3>- The area of the shaded sector depends on the area of the circle</h3>Step-by-step explanation:
Given central angle PQR = 45°
Total angle in a circle = 360°
Ratio of the measure of central angle PQR to the measure of the entire circle is . This shows ratio that <u>the measure of central angle PQR to the measure of the entire circle is one-eighth</u>.
Area of a sector =
= central angle (in degree) = 45°
r = radius of the circle = 6
Area of the sector
<u>The ratio of the shaded sector is 4.5πunits² not 4units²</u>
From the formula, it can be seen that the ratio of the central angle to that of the circle is multiplied by area of the circle, this shows <u>that area of the shaded sector depends on the length of the radius and the area of the circle.</u>
Since Area of the circle = πr²
Area of the circle = 36πunits²
The ratio of the area of the shaded sector to the area of the circle =
For length of an arc
ratio of the length of the arc to the area of the circle =
It is therefore seen that the ratio of the area of the shaded sector to the area of the circle IS NOT equal to the ratio of the length of the arc to the area of the circle
