Answer:
B.
Step-by-step explanation:
Total coins = 11 ( 3 + 4 + 4 = 11).
The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).
The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).
The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).
The probability of picking all three in that order = 3/11 x 2/5 x 4/9 = 8/165
The slope of the line passing the points (1, 1) and (0, 0) is 1
<h3>Slope of a line</h3>
The formula for calculating the slope of a line is expressed as
Slope = y2-y1/x2-x1
Given the coordinate points (1, 1) and (0, 0)
Substitute the given coordinate points
Slope = 0-1/0-1
Slope = -1/-1
Slope =1
Hence the slope of the line passing the points (1, 1) and (0, 0) is 1

For #19 part A :
By vertical angles and then same side interior angles 3x + 2x = 180
5x = 180
x = 36
For #19 part B:
You are correct with the 35, but you missed the fact that the 105 angle is supplementary with the unknown angle inside the triangle. So:
180 - 105 = 75
Then:
180 = 35 + 75 + x
180 = 110 + x
x = 70

Answer:
x=5
Step-by-step explanation:
2x+2-7=5
2x-5=5
2x=10
x=5
