There is 3.28084 feet in a meter
The answer is BC = 38.22 cm.
<u>Step-by-step explanation</u>:
We have, ∠BKD = 120° ,BK = 28 cm, Draw a perpendicular from point K on BC let it intersect at point M. In right angled ΔBMK, ∠BKM=30° and BK = 28 cm
sin30° = perpendicular/hypotenuse
1/2 = BM/BK
1/2 = BM/28
BM= 14 cm
Now , In right angled ΔBMK ,
cos30° = base/hypotenuse
√3/2 = MK/28
MK = 14√3 = 24.22 cm
KMCD is a square MK = MC = 24.22 cm
also, BC = BM + MC , putting values of BM & MC we get :
BC = 14 cm + 24.22 cm
BC = 38.22 cm.
1.60n<56
it should be greater than or equal to because if n is the amount of notebooks she can buy than n times 1.60 needs to be less or equal to $56
Y would equal 250 because 4*2=8 and 100*2=200 plus half of each so 8+2= 10 so now u have x and 200 plus 50 bc that’s half of 100 so now y=250
