Use Pythagorean theorem.
[tex]|ON|^2+|MN|^2=|OM|^2\\\\x^2+x^2=8^2\\\\2x^2=64\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=32\to x=\sqrt{32}\\\\x=\sqrt{16\cdot2}\\\\x=\sqrt{16}\cdot\sqrt2\\\\\boxed{x=4\sqrt2}
Answer: |MN| = 4√2.
Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
Answer:
A
Step-by-step explanation:
Answer:
13.5 miles or 27/5 miles
Step-by-step explanation:
2 7/10 is equal to 2.7 If she plans to run 5 times as much as last week, multiply 2.7 by 5.
2.7*5=13.5
The correct answer is 0.125. Each outcome is out of 8 possible outcomes. 1/8 = 0.125 . Therefore, 0.125 is your answer.
