Answer: 7290

Step-by-step explanation:

Three times is asking you to multiply the points before them by three. Level one, as we know is 10. Then, to get level two's points, you would multiply 10 by 3, to get 30, & so on.

Level One:10

Level Two: 10x3=30

Level Three: 30x3=90

Level Four: 90x3=270

Level Five: 270x3=810

Level Six: 810x3=2430

Level Seven: 2430x3= 7290

the numerator of a certain fraction is four times the denominator. If 10 is added to both numerator and denominator the resultin
ad-work [718]
Okay so will have x be the denominator. 
Numerator: 4x
Fraction: \frac{4x}{x} which would be equivalent to 4.
If you add 10 to both the numerator and denominator the resulting fraction is
\frac{4x + 10}{x + 10}= 2
We multiply both sides of the equal side sign times (x + 10) we get...
4x + 10 = 2 * (x + 10)
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5 < denominator
4x = 4 * 5 = 10 < So the fraction is 10/5

Devon says that triangles TUV and XYZ are similar because TU/XY UV/YZ XZ/TV what is wrong with his reasoning?
jeka57 [31]

Answer:

Devon use \frac{XZ}{TV} instead of \frac{TV}{XZ} in his reason. So, we can say that triangles are not similar.

Step-by-step explanation:

If two triangles are similar then their corresponding sides are proportional.

If triangle TUV and XYZ are similar, then

\frac{TU}{XY}=\frac{UV}{YZ}=\frac{TV}{XZ}

The reason given be Devon is

\frac{TU}{XY}=\frac{UV}{YZ}=\frac{XZ}{TV}

He use the correct concept, that the corresponding sides of similar triangle are proportional. But he use \frac{XZ}{TV} instead of \frac{TV}{XZ} in his reason.

Therefore his reason is incorrect. So, we can say that triangles are not similar.
