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
<h3>Length of the living space</h3>
Using the same scale ratio,
Hence, the length of the living space, in reality, is 21 meters.

Answer:
<h2><u><em>
8.17</em></u></h2>
Step-by-step explanation:
- <em>What is the number between 8.1 and 8.24?</em>
<em></em>
<em>Add the numbers and divide by 2 and you will find the average</em>
(8.1 + 8.24) : 2 =
8.17
8.17 is exactly half way between them.
Answer:
9
Step-by-step explanation:
They are alternate interior angles, so they most both equal 80.
9y-1=80
9y=81
y=9
Answer:
c
Step-by-step explanation:
In a multiple regression model X1 and X2 are two independent variables and the assumption is made that the effect of of X1 and X2 on dependent variables is independent of each other.For example let y be the student grade and x1 is the study hour and x2 be the IQ level of student so the multiple regression model for this scenario will be
Y=b0+b1x1+b2x2+e
Hence we can see that effect of study hour and IQ level on the student grade and the effect of study hour on the student grade is independent of the value of IQ level.
