Answer:
Amber rode for 36 minutes in total.
Step-by-step explanation:
Lets create a ratio table:
Time elpased (minutes) : Laps around park
9 : 1
36 : 4
Amber rode for 36 minutes in total.
To find this answer or you would divide the total volume by the volume of each box of candy. To find the volume of each box of candy you would multiply the length by the width by the height. 6 x 5 by 1/2 equals 15 in.³ per box. 64,000 is approximately 60,000, so 60,000÷15 = 4000 boxes approximately.
I think most of them are correct, you might wanna doubke check though! :)
answer: henri must make 160 brownies.
work:
set up as a system of equations.
= 
now, cross multiply to solve.
25(x) = 40(100)
25x = 4,000
now divide 4000/25.
4000/25 = 160.
40 is 25% of 160, so he must make 160.
