Answer:
140
Step-by-step explanation:
Given:
In the Stone Ridge apartment complex 35% of the apartments have one bedroom.
If there are 49 one bedroom apartments.
Question asked:
What is the total number of apartments at Stone ridge ?
Solution:
<u>Let total number of apartments at Stone ridge</u> = ![x](https://tex.z-dn.net/?f=x)
Now according to question:
35% of the total apartments having one bedroom = 49
![35\%\ of x = 49](https://tex.z-dn.net/?f=35%5C%25%5C%20of%20x%20%3D%2049)
![\frac{35}{100}\times x = 49](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B100%7D%5Ctimes%20x%20%3D%2049)
![\frac{35x}{100} = 49](https://tex.z-dn.net/?f=%5Cfrac%7B35x%7D%7B100%7D%20%3D%2049)
By cross multiplication:
![35x = 49\times100\\35x= 4900\\](https://tex.z-dn.net/?f=35x%20%3D%2049%5Ctimes100%5C%5C35x%3D%204900%5C%5C)
By dividing both sides by 35
![\frac{35x}{35} = \frac{4900}{35} \\x = 140](https://tex.z-dn.net/?f=%5Cfrac%7B35x%7D%7B35%7D%20%3D%20%5Cfrac%7B4900%7D%7B35%7D%20%5C%5Cx%20%3D%20140)
Therefore, total number of apartments at Stone ridge is 140
Answer: hope this helps
Step-by-step explanation:
Write down the numbers, one under the other, with the decimal points lined up.
Put in zeros so the numbers have the same length (see below for why that is OK)
Then add, using column addition, remembering to put the decimal point in the answer.
Answer:
-0.28
Step-by-step explanation:
(1/5) : (-5/7)=(1*5)/(5*(-5))=-(7/25)=-0.28
The best description of the geometric construction of the quotient z/w on the complex plane is; Option A; z is scaled by a factor of One-fifth and rotated 90 degrees clockwise
<h3>How to find Complex Trigonometric numbers?</h3>
We are given;
z = 3(cos(15°) + i sin(15°))
w = 5(cos(90°) + i sin(90°))
Now, if we want to find the quotient z/w, it is clear that in geometric construction, the procedure will be to scale z by a factor of 1/5 and thereafter we will rotate by 90° clockwise.
Thus, option A is the correct answer.
