Mai has ridden 18 miles of a bike course. the course is 60 miles long. what percentage of the course has mai ridden so far?

Mai has ridden 30% of the course

Step-by-step explanation: Course is 60 miles long, 15 × 4 = 60 ÷ 1/4 = 15, 6×10 = 60 and 6÷2 = 3. 15 would be 25% of the course, 3 would be 5% of the course. Add this together 15+3 = 18 miles you would get she's ridden 30% of the course

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
