Answer:
25 cents/ounce
Step-by-step explanation:
The unit rate means how much is one of the thing you are working with. In this case, the unit rate of a pint (16 ounces) is how much just one ounce will cost. So divide $3.93 by 16
$3.93/16 = $0.245625
Since we're working with money, round to the nearest hundredth
Unit rate is $0.25 per ounce, or 25 cents per ounce
Answer:
The correct answer is if you want no roots in the denominator, the correct answer is
* ![\sqrt[3]{2y^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2y%5E%7B2%7D%20%7D)
Step-by-step explanation:
The mistake is that you can't take a cube root of a square at step 3 when
is taken out.
First find the length of the diagonal of a square of side 4 inches:
d^2 = 4^2 + 4^2 = 2*4^2 = 32. Then the diagonal of the cube has length
sqrt( 32 + 4^2) = sqrt(32+16) = sqrt(48) = 4sqrt(3).
