Luke rides his bike 20 miles in 4 hours. if he rides at a constant speed, select the answers here that are equivalent ratios to the speed he rides. a: 30 miles in 7hrs b: 25 miles in 6 hours c: 10 miles in 1 hr d. 15 miles in 3 hrs

D. 15 miles in 3 hrs because he bikes 5 miles per hour (20 divided by 4=5)

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
