Answer:
2√42 ≈ 12.961
Step-by-step explanation:
All of the right triangles are similar, so ...
short leg/long leg = BC/AC = AC/CD
AC² = BC·CD = 7·24 = 168
AC = √168 = 2√42
Answer:
Of means multiply in math (most of the time).
So multiply.
2/5 x 7/10 = 14/50 divided by 2/2 = 7/25
Step-by-step explanation:
Alright, since there are 5 numbers, and the mean (or average) is (sum)/(amount of numbers), we have (sum)/5=14. Multiplying both sides by 5, we have the sum being 80. The median of 10 means that in a, b, c, d, e, 10 has to be c and the numbers have to be in ascending order. A and b must be 10 or lower, while d and e must be 10 or higher. Putting some random numbers in, we can have 1, 1, 10, 15, and e. We left e there because the sum needs to be 80, and since 1+1+10+15=27, 80-27=53=e. This, however, would not work if e was less than 10 and we therefore would have needed to make some numbers lower to compensate for this. Our answer is therefore 1, 1, 10, 15, 53
Answer:Take out your "like terms" out of the problem
2(y)- 16
2(2) = 4
4(y) - 8 = 0
y + 8 = 8y
8 + 0 = 8
We have one solution in this problem from the calculation we just did!
So, therefore your answer would have to be y=8
Answer:
choice. c.) (5, 1/2)
Step-by-step explanation:
(5, 4) and (5, -3)
Use midpoint formula ( (a + x)/2 , (b + y)/2) for (a,b), (x,y)
midpoint = ( (5+5)/2, (4+- 3)/2) = (5, 1/2)
