Jimmy drove to his cabin on the lake and back. it took 0.6 hours longer to go there than it did to come back. the average speed
Neporo4naja [7]
To answer this item, we let x be the distance that Jimmy drove from his origin and back. Given the speeds, the time it takes for him to travel to and fro are,
                                   t1 = x / 46
                                   t2 = x / 52
respectively.

The equation that would best represent the scenario is,
                              x/46 - x/52 = 0.6
The value of x from the equation is 239.2.

The trip there takes x/46 which is equal to 239.2/46 which is also equal to 5.2 hours. The travel from the cabin back took 4.6 hours.

Trig help please, 2 questions, 10 pts
Scrat [10]
1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700. 
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.

a = 3.14

<h3>What is the area?</h3>

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference   is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

a= pi*r^2

a = 3.14*1^2

a = 3.14
