A 5-mile race takes place along a straight course. The number line shows the distance, in miles, from start to finish. The race director would like to place a water station along the course such that the distance from the start to the water station and the water station to the finish line is in a 7:5 ratio. Where would the water station be located? Round to the nearest tenth of a mile, if necessary.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.

1200 inches = 30 yards12 inches= 1 foot3 feet= 1 yard3feet= 36 inchesyou can set up a proportion then use inverse operations that looks sorry it looks so sloppy lol
