Responder:
2³
5⁴
10³
a^6
Explicação passo a passo:
Quando um certo valor é multiplicado repetidamente,
Por exemplo,
a * a * a * a = a⁴ (a multiplicado 4 vezes)
Por isso,
2 x 2 x 2 = 2³
5 x 5 x 5 x 5 = 5⁴
10 x 10 x 10 = 10³
a x a x a x a x a x a = a^6
Trigonometry:
We know that csc x = 1 / sin x and π = 180°;
sin 5π/ 6 = sin 150° = 1/2
csc 2π / 3 = 1 / sin 120° = 1 / √3/2 = 2 / √3
Finally:
4 · 1/2 + 7 · ( 2 / √3 )² = 2 + 7 · 4/3 =
= 2 + 28/3 = 2 + 9 1/3 = 11 1/3
Answer:
About $0.10 per ounce
Step-by-step explanation:
12 pound costs $18.75. Lets find the cost per pound first:
Cost Per Pound = 
We know, there are 16 ounces in 1 pound.
We know 1 pound costs 1.5625
To find cost per ounce, we have to divide this by 16.
So,
Cost Per Ounce = 
Rounded to nearest cent, that would be 10 cents per ounce
