9-8.2-(-1.9) =
9-8.2+1.9
.8+1.9
2.7

-8-(-5.4)-1.8 =
-8+5.4-1.8
-2.6-1.8
-4.4

Alex has a higher score by 7.1.

The correct answer is a translation.

A rotation would change the direction, a reflection would change the direction, and a dilation would change the size.

I hope this helps :)

Are Triangles similar?
kvasek [131]

Given:

A figure of triangles.

To find:

Whether the triangles SPT and triangle QPR are similar.

Solution:

In triangle SPT and triangle QPR,

\angle PST\cong \angle PQR           (Given)

\angle SPT\cong \angle QPR           (Common angle)

In triangles SPT and triangle QPR, two corresponding angles are congruent. So, by AA property of similarity both triangles are similar.

\angle SPT\sim \angle QPR

Therefore, yes, the triangle SPT and triangle QPR similar. Option A is correct.

PLEASE HELP URGENT!!!
spin [16.1K]

Answer:

0.70

Step-by-step explanation:

According to the given question,

P(A) = 0.60

P(B) = 0.25

P(A and B) = 0.15

And we are asked to find P(A or B) ,

We know,

  • P(A or B) = P(A) + P(B)-P(A and B)

Putting the values we get,

  • P(A or B) = 0.60 + 0.25 - 0.15

  • P(A or B) = 0.70

Thus option B is correct one.
