You have to distribute the 3 first then combine like terms and divide to get n by itself so n=1/2
Answer:
300 doors.

1.5 minutes for 1 door.
7.5 hours for 300 doors.
7.5 hours = 450 minutes.
Answer:
none of the above. (Talk to your teacher about this question.)
Step-by-step explanation:
The differences between length and width are 4, 6, 12, so are not constant at either 4 or 6.
The ratio of width to length is 2/3, 2/3, 3/5, so is not constant at 2/3 or 3/2.
None of the answer choices (even after editing to add appropriate math symbols) describes the relation between length and width.
Wouldn't 2 squares make a rectangle and so you would add 10+10+18+18=56
56 is you answer.hope this helps
Answer:
r = 1728 units
Step-by-step explanation:
Volume of sphere: V = (4/3)(pi)(r^3), were r is the radius.
Solving this for r^3, we get
V V 7234.56 units^3
------------- = r^3 = ---------------- so that --------------------------
(4/3)(pi) (4/3)(3.14) 4.19
Thus, r = 1728 units
