Let us say that the number is x.
So the first step that Julio do is to cube the number so
that:
x^3
Then the next he did was take cube root of the number, so
that:
(x^3)^(1/3)
Solving this would result in:
x^(3/3) = x^1 = x
Since he ends up with 20, therefore:
x = 20
<span>Julio started and ended with the same number which is 20.</span>
Convert all to lb and find cost per 1lb
A.
54oz, convert to lb
54/16=3.375lb
find per lb
4.89/3.375=$1.4488888 per lb
B.
2 and 3/4=2.75, 3.91/2.75=$1.42181 per lb
C. 910/453.59=2.00621lb
3.10/2.00621=$1.545 per lb
compare
A: $1.4488888 per lb
B: $1.42181 per lb
C: $1.545 per lb
B is cheapest, followed by A then C
B is best buy
Answer:
n = 5/2
Step-by-step explanation:
(2n + 4) + 6 = -9 + 4(2n + 1)
2n + 4 + 6 = -9 + 8n + 4
2n + 10 = 8n - 5
15 = 6n
n = 5/2
Hope this helps!
Answer:
Assuming the given expression:m^2n^-3/m^6n^-1
then, both are correct. Whatever from both rule applies, it will yeild the same result. Both rules will be used either way, and the order in which they are applied does not matter as long as they are applied correctly at each step.
Answer:
100,800 seconds a week
Step-by-step explanation:
So first you would figure out how many minutes she spends each day watching so, 60 x 4 = 240
then how many seconds a day so 240 x 60 = 14,400 a day
now how many seconds a week 14,400 x 7 = 100,800
