Step-by-step explanation:
The person is mentioned is Phil. His amount of money and number of miles are proportionally related (Clark's amount of money and number of miles are not proportionally related due to initial donation)
For Phil, y = ax is his model.
Look into the graph, we can see there is a point where y = 30 and x = 4.
Then rate = 30/4 = 7.5
Answer:
3. 3 : 5; 3: 5
Step-by-step explanation:
First, let's find the leght of the sides of each octagon.
The area of an octagon is defined by
Replacing the area
Therefore, the side of the first octagon is 1.6 inches long.
Its perimeter is: 
Therefore, the side of the second octagon is 3.8 inches long.
Its perimeter is 
.
Now, let's divide to find each ratio:
(the ratio between sides).
(the ratio between perimeters).
Therefore, the closest ratio is 3. 3 : 5; 3: 5
Answer:
-6

<span>To find the circumference of a circle, you use the formula, pi x diameter. Pi=3.14. The diameter is not given to you in the question but we know that radius is half of diameter. So 10 times 2=20. Diameter =20. </span><span> multiply pi and the diameter. 3.14 x 20=62.8. </span>62.8 cm is your circumference
You answer is 184.19
Have a nice day!!
