A train ride at a carnival covers a distance of 3 miles in 20 minutes. Use a proportion to determine the speed for the ride in (blank) miles per 1 minute. (I also need help with this problem) Based on your findings, what is the speed for the ride in miles per hour. another question I have is, Jake makes 156 dollars in 2 weeks at his job with the traveling carnival. At this rate, how much does he make in a 52 week year. Set a proportion, show all your work. Please help.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

answer: you will have more water.

the answer is a.

606.0 sq. in.
