Answer:
Image result for If y is a positive integer, for how many different values of y is, ∛144/a whole number brainly
2 different values
Therefore, "y" must be a factor of 144. Therefore, for 2 different values of "y" ( and ) is a whole number
example
We need the remember that:
Therefore, the radicand (In this case ) must be a perfect cube in order to get a whole number.
Remember that a perfect cube are the numbers that have exact cube roots. Therefore, "y" must be a factor of 144.
Now, we need to descompose 144 into its prime factors:
Then, the factors of 144 are:
Substitute values into to check:
Answer:
800g
Step-by-step explanation:
10% of x = 80 g
x = 80 x 10
x = 800g
Answer: Look below
Step-by-step explanation:
10% = $120.90
1% = $12.09
11% = $132.99
$1,209 + $132.99 = $1,341.99
She made a $132.99 profit or $1,341.99
—————————————————————
8% = 96.72
$1,341.99 - $96.72 = $1245.27
————————————————
Or if it is $96.72 off the price she bought it then it would be
$1,209 - $96.72 = $1,112.28
