a. no. 9 x 15 = 135, so if she sells more than 15 necklaces, she'll make a profit
b. 50n > 135 + 4.50n
Answer:
its y=x+3
Step-by-step explanation:
i believe that because the chart starts off with three and it only uses it once it goes up 1 for the rest
Answer:
The answer is 7(tan 50°)
Step-by-step explanation:
So first you need to find which formula you will be using to do this you need to find if you're talking about the hypotenuse, opposite, or adjacent.
The side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side
The side which we do not know the length to will be the opposite side because it is opposite from where the angle is.
There are 3 formulas:
sin A = Opposite side/Hypotenuse = BC/AB
cos A = Adjacent side/Hypotenuse = AC/AB
tan A = Opposite side/Adjacent side = BC/AC
There is one formula that has Opposite and Adjacent which is tangent so thats the formula you'll use
Next you plug in the values that you have so your formula will look like this:
Tan 50° = x/7
A will always be where you plug in the angle and then you plug in the information according to what side it is
Every time that x is the numerator you will just multiply both sides by the denominator which gives you:
7(tan 50°)
Which is your answer :))
Answer: 12 and 7
Step-by-step explanation:
There are exactly 15 remainders modulo 15 and they are 0,1,2,…,14.
It is given that at least two of them should have the same remainder when divided by 15.
Division algorithm.
Let aa be an integer and d a positive integer. Then there are unique integers q and r with 
such that 
q is called the quotient and r is called the remainder
q=a div d
r=a mod d
Pigeonhole principle If k is a positive integer and k+1or more objects are placed into k boxes, then there is at least one box containing two or more objects.
Hence, there are exactly 15 remainders modulo 15 and they are 0,1,2,…,14.
