Answer:
144 bracelets
Step-by-step explanation:
Ashley is making bracelets to sell. She wants to make at least $450. Each bracelet costs $18 to make. She is selling them for $30 each. What is the minimum number she can sell to reach her goal
Let us represent the minimum number of bracelets she can sell= x
Hence, our Equation is
$18 + $30 × x ≤ $450
$18 + 3x ≤ 450
3x ≤ $450 - $18
3x ≤ $432
x ≤ $432/3
x ≤ 144
The minimum number of bracket = 144 bracelets
sin(45degrees) or BC/AB is 1/sqrt2(that's the value of sin45 degrees I recommend you to memorize this.)
x/12=1/sqrt2
x*sqrt2=12
x=12/sqrt2
Now rationalize this fraction to make the answer more formal.
x=12sqrt2/2(I multiplied both top and bottom by sqrt2)
Now simplify
x=6sqrt2
Question done! answer is C 6 square root of 2
Hope this helped any questions just put them in the comments.
I think the answer would be 90%
Answer:
Basically this is because division can be thought of as how many times does the divisor have to be multiplied in order to produce the dividend.
So you would need to multiply 1 8 times in order to produce the dividend,
Similarly, 10 goes into 80 8 times. The zeros are simply cancelled out in the division.
