Answer:

-12 degrees.

Step-by-step explanation:

We remember that to calculate the average, we must add all values, then divide by the amount of values.

This means the first 4 days sum to -8 while the first 5 days sum to -20. Therefore, on the fifth day, the temperature was -12 degrees.

Answer:

Step-by-step explanation:

Comparing the triangles in the given questions, the following can be deduced:

5. The scale factor = $\frac{15}{10}$ = $\frac{12}{8}$ ≠ $\frac{9}{7}$

So that;

QR is similar to UT, PR is similar to US, but PQ is NOT similar to TS.

Thus, the triangles are NOT similar.

6. Scale factor = $\frac{15}{10}$ = $\frac{12}{8}$ = $\frac{9}{6}$

= 1.5

So that;

QR is similar to UT, PR is similar to US, but PQ is similar to TS.

Thus, the triangles are similar by Side-Side-Side (SSS).

7. Here, an exact scale factor can not be determined. Thus, the triangles are NOT similar.
