x 
[yards/weight x yards/unknown weight]
11x = 4080
x = 370.9 or 371 pounds
Answer:
AB = BC = 4
Step-by-step explanation:
This is a 45-45-90 triangle (right isosceles). This means that the side ratio is
1:1:, where AC is sqrt 2, and AB and BC are 1. Now, we need to plug this into our ratio. If sqrt 2 is 8, then 1 is x.
8/ = x/1 = x
x = 8/ = 4 (rationalized)
AB and BC are both 4 * sqrt 2
Answer: 7 hours.
Step-by-step explanation: Randall can assemble 5 race car tracks in an hour and Diggery can assemble 4 race car tracks in an hour. To see how many hours it takes to make 63 race car tracks, you need to add 5 and 4, since Randall and Diggery are working together. Both of them combined can make 9 race car tracks in total every hour. 63 can be divided by 9, which is 7. Therefore, it'll take 7 hours for both of them to make 63 race car tracks.
Let me know if this is right! :)
