Answer: 0.382 ounces
Step-by-step explanation:
To find the unit rate of the weight of a single cookie, we will use division.
19.1 ounces per bag / 50 cookies in the bag = 0.382 ounces per cookie
To check our work, we will multiply 0.382 ounces per cookie by 50. Since the bag, with 50 cookies, weighs 19.1 ounces, 0.382 times 50 should equal about 19.1 ounces.
0.382 ounces * 50 cookies = 19.1 ounces ✓
Answer:
That's right!
Step-by-step explanation:
All of the points are in the right places! :P
X^a/b is
. The way I memorise that is x^1/3 is the cubic root of x. Do you get it? In that case, x is raised to a power of 1 and the cubic root is practically has a power of 3.
In your example,
is practically square rooting each term then cubing them individually. Remember when square-rooting any index you halve it. I'll elaborate:
=
= 4
Then cube each,
= 64
and
=
As for the 2nd part: you must use the rules of indices.
So breaking the question up:
3 * 3 = 9
stays as is since the 2nd term does not contain x
now:
This makes your final answer look like this:
I hope that helped and good luck in your test!
