Answer:
Step-by-step explanation:
Based on the information provided we can create the following direct proportion equation...
D = 3.5x
In this equation, the variable D represents the distance that Brianna has walked while the variable x represents the number of hours she walked. In this equation, the constant of proportionality would be the 3.5 miles that Brianna walks per mile. This value affects the entire equation because it is multiplied by the number of hours Brianna walks which is directly proportional to the Distance she travels, as one value increases so does the other.
Answer:
360
Step-by-step explanation:
The formula for the sum of an infinite geometric series is a₁/(1-r), where a₁ represents the first value and r represents the ratio. We can plug in our values here to get
a₁/(1-r) = 240/(1-1/3)
= 240 / (2/3)
= (240/1) / (2/3)
= (240/1) * (3/2)
= 360

Answer:
Step-by-step explanation:
Answer = 15 pi or about 37.12
Explanation: First you find the circumference using the formula c=2(pi)r. Radius = 18
C=2pi(18). Circumference= 36pi
Next find the measure of the arc. Multiply (36pi) by (150*degree of the arc*/360*total degree of a circle*). Plug into calculator.
