Answer:
1. A. 2. C. 3. C
Step-by-step explanation:
Break down $750. Where the first $500 is charged 1.5% and the remaining $250 is charged 1%
$500 * 1.5% = $7.50
$250 * 1.0% = $2.50
The total charge for the unpaid amount of $750 is $10.00
12 red + 16 blue + 18 white = 46 marbles
9. 3 marbles NO replacement: no white?
28/46 x 27/45 x 26/44
0.61 x 0.6 x 0.59 is about 22%
Each time we pick a red or blue we have one less to choose from next time
10. 4 marbles WITH replacement: all white?
18/46 x 18/46 x 18/46 x 18/46
0.39 x 0.39 x 0.39 x 0.39 is about 2%
11. 2 marbles NO replacement: red then blue
12/46 x 16/45
12 x 45 / 16 x 46
540/736
135/184 :)

Answer:
Step-by-step explanation:
In an isosceles trapezoid, two pairs of adjacent angles are supplementary. It means that the sum of the adjacent angles is 180°
Looking at the diagram, angle X and angle W are adjacent angles. It means that
X + W = 180
Since X = 105, then
105 + W = 180
W = 180 - 105 = 75°
Since W = b + 25°, then
b + 25° = 75
b = 75 - 25 = 50°
