The value of n in given proportion is 16
<em><u>Solution:</u></em>
We have to find the value of "n" in the proportion
<em><u>Given proportion is:</u></em>
![\frac{n}{28} = \frac{4}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B28%7D%20%3D%20%5Cfrac%7B4%7D%7B7%7D)
We can solve the above proportion by cross-multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable
![\rightarrow \frac{n}{28} = \frac{4}{7}\\\\\rightarrow 7 \times n = 4 \times 28\\\\\rightarrow n = \frac{4 \times 28}{7}\\\\\rightarrow n = 4 \times 4 = 16](https://tex.z-dn.net/?f=%5Crightarrow%20%5Cfrac%7Bn%7D%7B28%7D%20%3D%20%5Cfrac%7B4%7D%7B7%7D%5C%5C%5C%5C%5Crightarrow%207%20%5Ctimes%20n%20%3D%204%20%5Ctimes%2028%5C%5C%5C%5C%5Crightarrow%20n%20%3D%20%5Cfrac%7B4%20%5Ctimes%2028%7D%7B7%7D%5C%5C%5C%5C%5Crightarrow%20n%20%3D%204%20%5Ctimes%204%20%3D%2016)
Thus the value of n in given proportion is 16
Getting at least a 80% ( B average) is also good still very close to 90
Answer:
no it's 4540
Step-by-step explanation:
you just subtract 5220 from 9760 and you get your difference
To find the area, you would use the formula Area= Length times Width.
To find the perimeter, you would add up the length of all sides.
