15) D a box of paper clips and 16) C Computation
hi
first case is : 2^0 = 1 , then each case is 2^(n-1) where "n" is the number of the case.
so case 3 is 2^(3-1) = 2^2 = 4 and case 64 is 2^(64-1) = 2^63
Sams club because you get 10 can with just a little bit of a difference price
You first need to find the last angle measurement which is
60 because 60+15+105= 180
Sin60 Sin105
——— = ———— Cross multiply
a 2
Sin60 * 2 = Sin105*a
1.7 = Sin105*a Divide both sides by sin105
1.79 = a
1.8 ≈ a
Answer: 80% of 50 equals 40
