Answer:
The answer to your question is: AC = 36
Step-by-step explanation:
Data
Segment AC with midpoint = B
AC = 5x - 9
AB = 2x
AC = ?
Process
total length = AC but B is the midpoint so AB + AB = CA
2AB = CA
Substitution 2(2x) = 5x - 9
4x = 5x - 9
Solve for x 4x - 5x = -9
-1x = -9
x = -9/-1
x = 9
Finally, AC = 5x - 9
= 5(9) - 9
= 45 - 9
= 36
There are a couple of different approaches you can use for this. Here's one.
1. Determine how many digits repeat. (There is just one repeating digit.)
2. Call your number x. Multiply x by 10 to the power of the number of digits found in step 1.

3. Subtract the original number, then solve for x.

If you recognize that 0.333... (repeating) is 1/3, then you know that 0.0333... (repeating) is 1/10×1/3 = 1/30. Add that to 0.8 = 4/5 and you get
... 4/5 + 1/30 = 24/30 + 1/30 = 25/30 = 5/6
I think the answer is B. 55. Butbi would cheat to make sure.
Answer:
4 sqrt(2) =c
Step-by-step explanation:
The base is the triangle
We can use the Pythagorean theorem to solve
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
4^2 + 4^2 = c^2
2 * 4^2 = c^2
Take the square root of each side
sqrt(2 * 4^2) = sqrt(c^2)
sqrt(2) *sqrt( 4^2) = c
4 sqrt(2) =c
Answer:
In standard form x^2/64 + y^2/100 = 1
Step-by-step explanation:
The major axis is the y axis because 10 has a larger value than 8.
8x8 = 64
10 x10 = 100
