Area of a rectangle is 27 cm²

Given:

Perimeter of a rectangle = 24 cm

Length = 3x

Width = x

p = 2(l + w)

24 = 2(3x + x)

24 = 6x + 2x

24 = 8x

24/8 = x

3 = x 

Width = 3 cm ; Length = 3x = 3(3) = 9 cm

Area = length * width

        = 9cm * 3 cm

Area = 27 cm²

Alenkinab [10]

The measure of dispersion that measures how much the data differ from the mean is called the standard deviation.

<h3>What is standard deviation?</h3>

Standard deviation is a statistical measure of dispersion as opposed to the measure of central tendency like mean, median and mode.

The standard deviation is a measure of how spread out data values are around the mean.

It is defined as the square root of the variance and represented with the Greek letter σ.

David's dinner cost $24. He wants to leave a 20% tip. The tax rate is 8%. What is the total he will pay? (not $31.10)
Hitman42 [59]

Answer:

$30.72

Step-by-step explanation:

You were right with your answer, the teacher is probably just wanting you to tip on the subtotal (before tax) instead of the total total. Instead of doing total+tax+tip, we're going to figure out the tax and tip separately and then add it all together.

<u>Tipping on the subtotal (what your teacher wanted)</u>

20% of $24 = $4.80

8% of $24 = $1.92

$24+$4.80+$1.92=$30.72

<u>Tipping on the total (what you did)</u>

8% of $24 is $1.92

New total is $25.92

20% of $25.92 is $5.18

$25.92 + $5.18 = $31.10
