Answer:

The first plan of $49 will be best plan for her.

Step-by-step explanation:

Katherine used 1479 minutes call in the last 6 months.

So, the average monthly call that Katherine made is \frac{1479}{6} =246.5 minutes.

Now, there are two plans for mobile recharge.

One is 250 minutes call time for $49 and the other is 350 minutes call time for $65.

Since 246.5 < 250 and Katherine does not want to spend more for minutes she won't use, then the first plan of $49 will be the best plan for her. (Answer)

Answer:

  4th choice (if we guessed the blurry letters properly)

Step-by-step explanation:

The reflection maps ...

  (x, y) ⇒ (x -y)

Then the rotation maps ...

  (x, -y) ⇒ (y, x)

That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.

The frame around a picture with an area of 192 square inches, measures x inches across. The length of the picture with its frame
prisoha [69]
Okay so
area of picture= 192cm
area of frame= 40×24=960

960÷ 192= 5

Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24

The dimensions of the picture are then 8cm × 24 cm.
