Answer: 1/5
Step-by-step explanation:
There are 10 numbers, out of 50, which have a 4 in their tens place: 40, 41, 42, 43, 44, 45, 46, 47, 48, and 49.
Therefore our desired probability is 10/50 or 1/5.
(2x-10)/4 = 3x
2x - 10 = 12x
10x = -10
x = -1
Answer:
I believe the answer is D
Step-by-step explanation:
I did it by eliminating all other options
A cant be true because with a 90 degree rotation RS is going to be perpendicular to R'S', not parallel.
B can't be true because SP is a straight line and R'S' like RS wont be (rotation doesn't change the fact that it isn't a completely straight line.
Now, rotation doesn't affect the degree of an angle. so...
C can't be true because 60 degrees isnt just going to change to 80 degrees out of nowhere
but D can be true because of this rule.
I hope this helps!
