7/8+5/12 is 12/20 GCF of 4 and it simplifies to 3/5
Answer: $46.08
Step-by-step explanation: starts at 36....marks up by 60%
36 + 0.60(36) = 36 + 21.60 = 57.60
now they mark it down by 20%
57.60 - 0.20(57.60) = 57.60 - 11.52 = 46.08
Answer:
249.42 units²
Step-by-step explanation:
Given only the apothem of an n-sided regular polygon, the area can be computed as ...
... A = n·a²·tan(180°/n)
For n=3 and a=4√3, this is ...
... A = 3·(4√3)²·tan(60°)
... A = 3·48·√3 = 144√3 . . . . units²
... A ≈ 249.42 units²
Answer:
wait it keeps timing me ima write my answer in comments
Step-by-step explanation:
You have to combine -5.8c+1.4c which = -4.4c
then
combine 4.2-3.1 which = 1.1
so the answer is
-4.4c+1.1 or you can switch the numbers around
