Answer:
the answer is 40.5!
Step-by-step explanation:
First, you have to add all of the numbers up!
Answer:
$0.067
Step-by-step explanation:
Total cost of 16 bags = $12.80
weight in 1 bag = 12 ounce
weight in 16 bag = 16 * weight in 1 bag
weight in 16 bag = 16* 12 ounce = 192 ounce
Thus,
192 ounce cost = Total cost of 16 bags= $12.80
cost of 182 ounce = $12.80
to find cost of 1 ounce , we divide both side by 182
cost of 1 ounce = 12.80/192 = $0.067
Thus,
the unit cost per ounce is $0.067
Answer:
C
Step-by-step explanation:
Trust me, take the square root of 24, which divides into 2 x 2 x 2 x 3, and you pull a pair of 2 out, left inside a 6
It would be negative six.
Throughout all of these steps I'm only going to alter the left hand side (LHS). I am NOT going to change the right hand side (RHS) at all.
Before I change the LHS of the original equation, let's focus on the given identity
cot^2(x) + 1 = csc^2(x)
Since we know it's an identity, we can subtract 1 from both sides and the identity would still hold true
cot^2(x) + 1 = csc^2(x)
cot^2(x) + 1-1 = csc^2(x)-1
cot^2(x) + 0 = csc^2(x)-1
cot^2(x) = csc^2(x)-1
So we'll use the identity cot^2(x) = csc^2(x)-1
---------------------------------------------
Now onto the main equation given
cot^2(x) + csc^2(x) = 2csc^2(x) - 1
cot^2(x) + csc^2(x) = 2csc^2(x) - 1 .... note the term in bold
csc^2(x)-1 + csc^2(x) = 2csc^2(x) - 1 .... note the terms in bold
[ csc^2(x) + csc^2(x) ] - 1 = 2csc^2(x) - 1
[ 2csc^2(x) ] - 1 = 2csc^2(x) - 1
2csc^2(x) - 1 = 2csc^2(x) - 1
The bold terms indicate how the replacements occur.
So the original equation has been proven to be an identity because the LHS has been altered to transform into the RHS
