Answer: They were marching for 32 minutes.
Step-by-step explanation: If you multiply the 4/5 times by 60 minutes (1 hour), then you will get 48 minutes. 48 minutes is the time of the band practice. Once you get that, then multiply that by 2/3 to get the amount of minutes marching. Once you multiply 2/3*48, you will get 32, which is how many minutes they were marching during band practice.
Answer:
9
Step-by-step explanation:
since they're similair then similair sides will be proportional
CB is similair to EF
=
same thing if you try with the hypotenuse AB similair to DE
=
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
r=16
6,2,7
1,2,1
Pretty sure but double check with someone else.
