Answer:
90 pairs
Step-by-step explanation:
We can use clues from the problem in order to set up our inequality.
First, we know that a pair of earrings, 
, costs $8.50. So, we can say that 
total profit.
That's a function we could use, but we need an inequality. Well, it says that Stephanie wants to make no less, or <u>at least</u> $765. This indicates that we need the 'greater than or equal to' symbol. Just replace the equal sign:
Now we can isolate to find how many earrings she needs to sell to make a profit of at least $765.
Stephanie needs to sell at least 90 pairs of earrings.
Hope this helps!
Answer:
Required coefficient :coefficient of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.
Explanation:
Formula for binomial expansion is 
We will substitute the values a=a, b=b and n=3 in the formula for binomial expansion we will get
After simplification of the terms we will get
Since, 
Therefore the required coefficient : coefficients of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.

Step-by-step explanation:
In the following triangle, a= ? , b= 2cm.
m<B= 105° , m<C = 15° ,m< A =?
Now, we know that sum of the interior angles of the triangle = 180°
m<B+m<C +m< A =180°
105°+15°+m< A=180°
m< A= 180- 120° = 60°
