Answer:
<em>Correct choices: a) 5:12 and c) 7 to 12</em>
Step-by-step explanation:
The ratio of red beads to pink beads is 5:7. This means that for every 5 red beads there are 7 pink beads.
It also means that for every 12 beads there are 5 red beads and 7 pink beads.
Therefore, there are two part-to-whole ratios:
5:12 red beans to total beads, and
7:12 pink beans to total beads
Correct choices: a) 5:12 and c) 7 to 12
A)If the order of the speakers is important, we have 20x19x18x17, or 116,280 different options.
b) If order is not important, then we have 20 choose 4, or 4845 different slates. ☺☺☺☺
10 in; if the original 100% was 5 in, then you multiply that by 2.
D
using the double - angle identity
cos (2A) = cos² A - sin² A = 2cos² A - 1 = 1 - 2sin² A
the right side = 1 - 2sin² (112.5° ) with A = 22.5°
hence 2A = 2 × 22.5° = 45°
thus cos 45° = 1 - 2sin² ( 22.5°)
