To solve the problem we must know about the Ratio.
<h2>What is Ratio?</h2>
A ratio shows us the number of times a number contains another number.
The length of the living space, in reality, is 21 meters.
Given to us
- The scale is given as 2 centimeters equals 2.5 meters.
To find
- the actual length of the living space if the length of the scale drawing is 16. 8 centimeters
<h3>Scale ratio</h3>
As it is given that 2 cm on the scale drawing is equal to 2.5 meters in real, therefore, the ratio can be written as
![\dfrac{\text{Length of the scale drawing}}{\text{Length in reality}} = \dfrac{2\ cm}{2.5\ meters}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BLength%20of%20the%20scale%20drawing%7D%7D%7B%5Ctext%7BLength%20in%20reality%7D%7D%20%3D%20%5Cdfrac%7B2%5C%20cm%7D%7B2.5%5C%20meters%7D)
<h3>Length of the living space</h3>
Using the same scale ratio,
![\dfrac{\text{Length of the living space in scale drawing}}{\text{Length of the living space in reality}} = \dfrac{2\ cm}{2.5\ meters}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BLength%20of%20the%20living%20space%20in%20scale%20drawing%7D%7D%7B%5Ctext%7BLength%20of%20the%20living%20space%20in%20reality%7D%7D%20%3D%20%5Cdfrac%7B2%5C%20cm%7D%7B2.5%5C%20meters%7D)
![\dfrac{16.8}{x} = \dfrac{2\ cm}{2.5\ meters}\\\\x=\dfrac{16.8 \times 2.5}{2} = 21\ meters](https://tex.z-dn.net/?f=%5Cdfrac%7B16.8%7D%7Bx%7D%20%3D%20%5Cdfrac%7B2%5C%20cm%7D%7B2.5%5C%20meters%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B16.8%20%5Ctimes%202.5%7D%7B2%7D%20%3D%2021%5C%20meters)
Hence, the length of the living space, in reality, is 21 meters.

Step-by-step explanation: just did it on apex. good luck!
Answer:
The student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
They all can be divided by 12 which is the largest number they can be divided by so 12
So we have a total of 39000
and a total of 9+4 parts to split it in
so split 39000 into 13 parts
39000/13 = 3000
9:4
9(3000) : 4(3000)
27000:12000
