Answer:
x = 1/18
Step-by-step explanation:
The answer would be 2/7, because 3 and 5 are the only factors of 15. 2/7 which is about 29 percent.
10 2/6= Becomes 9 8/6
-21/2= 3/6. -2 3/6
Answer 7 5/6 tons
Answer:
B. 10
Step-by-step explanation:
First, we need to recognize that the two triangles are similar (the triangle with a leg value of 21 and the triangle with a leg value of 4 and hypotenuse x)
Let's first label the leg of the second triangle as y.
Then, we can set up this equation

Cross multiplying gives us
84=y^2
So, y=sqrt(84) or 2 sqrt(21).
Now, using the pythagorean theorem, we get
4^2+2sqrt(21)^2=x^2
100=x^2
x=10
