$2.00 in quarters is 8 quarters, since 1 quarter is 25 cents.
Out of those 8 quarters, only 3 are state quarters.
That means 5 are not state quarters.
So there is a 5/8 chance that the first quarter he takes out is not a state quarter.
If it is not, then there are 3 state quarters and 7 total quarters left, which means a 4/7 chance that the second quarter is not a state quarter.
To find the probability of both of these quarters not being state quarters, multiply the probabilities by each other.
4/7 • 5/8 = 20/56
Now simplify:
20/56 = 10/28 = 5/14
5/14 is in simplest form, so it is the answer.
So the answer is D. 5/14.
Answer:
Neither
Step-by-step explanation:
They do not form a 90° angle(so it's not perpendicular)
And they touch(so it's not a parallel)
I 'll suggest you solve it on CY math calculator it even shows you steps and it is free and if yo got really big answer that's correct because I checked your question on CY math calculator it was really big and the answer was
y = 883.4235323892×<span><span>10^ -168
to confirm your answer is correct check it on CY math calculator .

Answer:
B. 60°, 60°, 60°
Step-by-step explanation:
All triangle angles add up to 180
A) NOPE
50 + 45 + 45 = 140
B) YUP
60 + 60 + 60 = 180
C) NOPE
70 + 70 + 70 = 210
D) NOPE
80 + 55 + 25 = 160
