Answer:
Step-by-step explanation:
C.
To do this, we must set up ratios:
Option One:
The first options costs only
$0.0092/gram (a fraction of a penny)!
Option Two:

The second option costs only
$0.0085/gram (cheaper than option one)!
Option Three: This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore,
1,000g costs $5.65. Next, we set up the ratio as usual:

The third option costs
$0.00565/gram.
Therefore,
option three is the cheapest! Hope this helps!
Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ = 
Cosθ = 
tanθ = 
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ = 
θ = 
Option (A) will be the answer.
Answer:
m = 56
Step-by-step explanation:
1/2m - 5 = 23
add 5 to both sides
1/2m - 5 + 5 = 23 + 5
1/2m = 28
multiply both sides by 2
1/2m(2) = 28(2)
m = 56
