What do you round 150 to??
Vedmedyk [2.9K]
It depends on what you are rounding off to.

If you are round it off to the nearest ten, you must look at the unit number.
If you are rounding off to the nearest hundred, you must look at the ten number.

In this case I think they are asking to round to the nearest hundred. Now we must look at the ten number, which is the number after the 'hundred' number.

The ten number is '5' and the hundred number is '1'. If the ten number is 5 or above, it changes to 0 and it makes the hundred number one higher.

So because the ten number is 5, it changes to 0 and it makes the hundred number one higher, to become 2.

The number is now 200.

The length of a rectangular picture frame is 2 inches shorter than its width. If the perimeter of
jok3333 [9.3K]

Answer:

Length = 12 inches

Width = 14 inches

Step-by-step explanation:

Formula for perimeter of a rectangle is;

P = 2(L + W)

Where;

L is length

W is width

We are told that the length is 2 inches shorter than its width. Thus;

L = (W - 2)

Thus,perimeter is now;

P = 2(W - 2 + W)

P = 2(2W - 2)

P = 4W - 4

We are told that the perimeter is 52. Thus;

4W - 4 = 52

4W = 52 + 4

4W = 56

W = 56/4

W = 14 inches

From L = (W - 2) ;

L = 14 - 2

L = 12 inches

Compare the average score of a student at the beginning of a month and at the end of that month, if at first, it increased by 40
IceJOKER [234]

Answer:

Increased by 5%

Step-by-step explanation:

Let at the beginning the student's score be s points.

At first, it increased by 40%. So, the new score is

s+0.4s=1.4s

Then it decreased by 25%, so the new score is

1/4s-0.25\cdot 1.4s=1.4s-0.35s=1.05s

At the beginning of a month the score was s and at the end of that month the score was 1.05s. Since 1.05>1, the score increased by 1.05-1=0.05=5\%
