Answer:
$0.02
Step-by-step explanation:
Brand a
1.28 ÷ 8 = 0.16 per ounce
Brand b
1.68 ÷ 12 = 0.14 per ounce
0.16 - 0.14 = 0.02
Answer:
a = 7.21
Step-by-step explanation:
Remark
This just uses a^2 + b^2 = c^2. You know 2 of the three things there.
<em><u>Givens</u></em>
Solution
a^2 + b^2 = c^2 Substitute the givens
a^2 + 12^2 = 14^2 Expand
a^2 + 144 = 196 Subtract 144 from both sides
a^2 = 196 - 144 Collect like terms on the right
a^2 = 52 Take the square root of both sides.
sqrt(a^2) = sqrt(52)
a = 7.2111
a = 7.21 Answer
