Answer: 8 5/8 turns
Step-by-step explanation:
Hi, to answer this question we have to simply to multiply the number of turns that the windmill makes per hour (5 3/4) by the time asked (1 ½ hours).
Mathematically speaking:
5 3/4 x 1 1/2 = (5x4+3)/4 x (1x2+1)/2 = 23/4 x 3/2= 69/8 or 8 5/8 (mixed form)
In conclusion, the windmill makes 8 5/8 turns in 1 1/2 hours.
100 sandwiches, using bun packages of 8...
100/8=12.5 Since you cant buy a half a package, round up to 13 packages
100 sandwiches, using bun packages of 12...
100/12=8.33 Since you cant have a third of a package, round up to 9 packages
6n=0.12
n=0.12:6
n=0.02
Answer: n=0.02
X = 2
So 6 + 2 = 8
6 - 2 = 4
8 x 4 = 32
(6-x)(6+x) = 32
36 - x^2 = 32
-36. -36
-x^2 = -4
X = 2
