user100 [1]

Answer:

It will take 11 minutes

Step-by-step explanation:

660 ÷ 60 = 11

Distance= rate×time

D=rt

660 (distance)= 60 (feet per minute or rate) × t (we have to find out the time it takes to get there.

We divide 660 by 60 to find the missing value, which is 11.

-Dominant- [34]

Answer:

C) 3 times the sq root of 3

Step-by-step explanation:

In a right angle triangle, the COS is definned as the ajacent side over the hypotenuse. So

COS 60 = JK/JL

COS 60 = JK/(6*sq root 3)

.5 = JK/(6*3**1/2)

JK = .5 *(6*3**1/2)

JK = 3*3**1/2
