How many pounds each of a soybean meal at 16 percent protein and cornmeal at 8 percent protein should be mixed together in order to get 320-lb mixture that is 14 percent protein?
Let S be the amount in pounds of soyabean meal and C be the amount in pounds of cornmeal.You can create two equations relating S & C by considering the amount of protein and total weight:16% S + 8% C = 14% of 320 lbS + C = 320 lbwhich can be used together to solve for S and C:subtract 6¼ times {1} from {2} to get:S - 16%S × 6¼ + C - 8% C × 6¼ = 320 - 14 × 6¼ of 320→ 100% S - 100% S + 100% C - 50% C = 100% of 320 - 87½% of 320→ 50% C = 12½% of 320→ C = 25% of 320 = 80Now substitute for C in {2}:S + 80 = 320→ S = 240Therefore you need 240lb of soyabean meal and 80 lb of cornmeal.
What is C in the equation -14 plus c plus 6 equals -5?
-14 + c + 6 = -5-14 + c = -5 minus 6-14 + c = -11c = -11 minus -14c = -11 plus 14c = 3
How many degrees F is 14 degrees C?
14 deg C = 57.2 deg F.
How do you find the chord of a 35 degrees arc in a circle of radius 14 inches?
Use the Law of Cosines: c^2 = a^2+b^2-2ab cos C. Here, the two legs of a triangle are both the radius (14 inches long), and the angle between them is 35 degrees. So c^2 = 14^2+14^2-2*14*14*cos 35 c^2 = 2*14^2(1-cos 35) c^2 = 70.89.. c = 8.42..
