If you turn all the numbers into decimals it becomes, -6.25, -6.35, -6.20, and, 6.1 so in order it would go 6.1, -6.20, -6.25, -6.35
5/100=0.05
0.05*45.90=2.295
$2.30 is the tax. Feel free to correct this If wrong.
Answer:
a) 165.52 degrees.
b) 131.41 degrees.
c) 118.96 degrees.
d) 159.73 degrees.
Step-by-step explanation:
The sine of an obtuse angle is positive as it is in the second quadrant.
a) Using a calculate the angle whose sine ( arcsin) is 0.25 = 14.478 degrees
so the obtuse angle = 180 - 14.478 = 165.52 degrees to nearest hundredth
b) c) and d) are calculated in the same way.
Probability = option(s) that we want / total number of possibilities
Options that we want = cash or credit card = 50 + 4 = 54
Total number of possibilities = cash, debit card, credit card = 50 + 2 + 4 = 56
54 / 56 = 0.96
Answer: 0.96
Hope this helps!
False
lets say u have 2 sets of points (1,2) , (3,4)
now lets say (1,2) is (x1,y1) and (3,4) is (x2,y2)
slope = (y2 - y1) / (x2 - x1)
slope = (4-2) / (3-1) = 2/2 = 1
now, lets say (1,2) is (x2,y2) and (3,4) is (x1,y1)
slope = (y2 - y1) / (x2 - x1)
slope = (2 - 4) / (1 - 3) = -2/-2 = 1
in conclusion, the naming of the points will not effect the slope
