What ratios that are equivalent to 4 to 7.
expeople1 [14]
4 to 7 =  4/7

5/8 is not.

12/20 = 6/10 = 3/5 . It is not equivalent.

8:14 = 4 : 7 .  It is equivalent

5 to 10 = 1 to 2.  It is not.

16/28 = 8/14 = 4/7.  It is equivalent.

9 to 16 = 9 to 16.  It is not equivalent.

So only 8:14 and 16/28  are equivalent to 4 to 7.

Let W= { (x, y, z) |x=1|; y, z ∈ℝ } Prove that W is a subspace of ∈ℝ<br> How can I resolve this ?
Nataly [62]

Answer:

W is not a subspace.

Step-by-step explanation:

Notice that (-1,2,2) and (-1,5,3) are both elements of W. Because its x coordinate, x = -1, satisfy the condition |x| = 1.

but (-1,2,2) + (-1,5,3) = (-2,7,5) do not belongs to W. Because its first coordinate, x =-2, do not satisfy |x| = 1.

Find the length of the missing side please help
kozerog [31]

Step-by-step explanation:

7. Since they are similar triangles we have:

\frac{10}{8}  =  \frac{x}{12}  \\  \\ x = 15

So DF is 15

8. They are also similar. So:

\frac{14}{7}  =  \frac{x}{5}  \\ x = 10

So PR is 10
