Answer:

<h2>All four interior edges are 4 inches, 3 inches, 4 inches and 3 inches.</h2>

Step-by-step explanation:

Givens

  • The area of the frame is 18 square inches.
  • The wide of the frame is 1 inch.
  • One of the outer edges of the fram is 5 inches long.

If one side is 5 inches long and the wide is 1 inch, then the inner side is 3 inches long, becase we must subtract the 2 inches of the wide.

The image attached shows all relations we need to make regarding both areas.

The inner area is defined as

A_{inner}=(b-2)3

The area of the whole

A_{whole}=5b

The area of the frame is defined as the difference of the inner area and the whole area

A_{frame}=A_{whole}-A_{inner}\\  18=5b-3(b-2)

Now, we solve for b

18=5b-3(b-2)\\18=5b-3b+6\\18-6=2b\\b=\frac{12}{2}\\ b=6

The interior each is defined as b-2, so its length is

b-2=6-2=4

Therefore, the interior edges are 4 inches and 3 inches long.

All four interior edges are 4 inches, 3 inches, 4 inches and 3 inches.

Help plz I'm desperate ​

<u>Anna:</u>

1st month = 18 + \frac{3}{4} = 18\frac{3}{4} inches

2nd month = 18\frac{3}{4} + \frac{3}{4} = 19\frac{1}{2}

3rd month = 19\frac{1}{2} + \frac{3}{4} = 20\frac{1}{4}

4th month = 20\frac{1}{4} + \frac{3}{4} = 21

5th month = 21 + \frac{3}{4} = 21\frac{3}{4}

<u>Grace:</u>

Because Anna is \frac{9}{4} inches shorter than Grace, we can start the count from the third month:

1st month = 20\frac{1}{4}

2nd month = 21

3rd month = 21\frac{3}{4}

4th month = 21\frac{3}{4} + \frac{3}{4} = 22\frac{1}{2}

5th month = 22\frac{1}{2} + \frac{3}{4} = 23

Digiron [165]

Answer:

10 hours

Step-by-step explanation:

45 pages per 1 hour and 30 minutes,  or 60 min +30 min =90 min

90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages

90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300

? minutes = 90*300/45 = 600 minutes

to read 300-page book will take 600 minutes = 10 hours

Svetach [21]

Answer:

I believe the answer is- The mean and MAD can accurately describe the "typical" value in the symmetric data set.

Step-by-step explanation:

The other answers don't make sense because the mean and MAD are being used for symmetrical distributions and asymmetrical means uneven distributions.
