The answer is 1/12.
The perimeter of a square garden with side s is:
P = 4s
s = 1/4P
Since it is painted 1/3 of 1/4 of the fence, the<span> fraction of the painted fence is:
1/3 * 1/4 = 1/12</span>
72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
Answer:
horizontal and vertical
Step-by-step explanation:
if its the plus?
Answer:
30 mph
Step-by-step explanation:
Let d = distance (in miles)
Let t = time (in hours)
Let v = average speed driving <u>to</u> the airport (in mph)
⇒ v + 15 = average speed driving <u>from</u> the airport (in mph)
Using: distance = speed x time

Create two equations for the journey to and from the airport, given that the distance one way is 18 miles:

We are told that the total driving time is 1 hour, so the sum of these expressions equals 1 hour:

Now all we have to do is solve the equation for v:







As v is positive, v = 30 only
So the average speed driving to the airport was 30 mph
(and the average speed driving from the airport was 45 mph)
Answer:
x = 0 y = 2
Step-by-step explanation:
4x + 2 = -2x + 2
6x + 2 = 2
6x = 0
x = 0
y = 4(0) + 2
y = 2
