Answer:
you could do 4y times 2y which would be 80y plus 2y times 2y which would be 40y so then 40 y plus 80y equals 120y

Answer:
76 % of babies will be born out of wedlock in the
year
Step-by-step explanation:
Given: In 1990, 28 % of babies in the United States were born to parents who were not married. This increased by approximately 0.6 % per year.
To find: year when 76 % of babies born out of wedlock
Solution:
A sequence is said to be in arithmetic progression if the difference between the terms is same.
For a sequence with first term as 'a' and common difference as 'd', the nth term is given by 
The given situation also forms an arithmetic progression with 
Also, put 
So,

So, 76 % of babies will be born out of wedlock in the
year

Step-by-step explanation:
Answer:
Langdon is not correct. It means distributive property is not applicable for sines of angles.
Step-by-step explanation:
According to Langdon

We need to check whether Langdon is correct or not.
Taking LHS,


![[\because \sin 30=\frac{1}{2}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%2030%3D%5Cfrac%7B1%7D%7B2%7D%5D)

Taking RHS,

![[\because \sin 60=\frac{\sqrt{3}}{2}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%2060%3D%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%5D)
Since LHS ≠ RHS, therefore Langdon is not correct.
It means distributive property is not applicable for sines of angles.
