**Answer:**

the anwser is 27

**Step-by-step explanation:**

glad I could help!

The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.

The angle to the right of y is given as 48.

The three inside angles of a triangle need to equal 180.

So y = 180 - 90 - 48 = 42 degrees.

**Answer:**

7630

**Step-by-step explanation:**

We have that the distance of a comet from Earth is about 7.63*10³ .

This number is given in scientific notation.

We want to write this number in standard form.

Since we are multiplying by a power of 10, we move forward three times.

Therefore in standard form:

Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minute. Plan B involves a fixed charge of $15 per month and call charges at $0.08 per minute.

Plan A $10 + .10/minute

Plan B $15 + .08/minute

If 250 minutes are used:

Plan A: $10+$25=$35

Plan B: $15+$20=$35

If 400 minutes are used:

Plan A: $10+$40=$50

Plan B: $15+$32=$47

B is the correct answer. How to test it:

Plan A: $10+(.10*249 minutes)

$10+$24.9=$34.9

Plan B: $15+(.08*249 minutes)

$15+$19.92=$34.92

Plan A < Plan B if less than 250 minutes are used.
