Answer:
B), x=-1, y=-2, z=1.
Step-by-step explanation:
What is that really supposed to mean
Answer:
Around 115 apples
Step-by-step explanation:
Lets convert 6 lbs to ounces
1 pound is 16 ounces
6 lbs * 16 ounces/ 1 lbs = 96 ounces
We can use ratios to determine how many ounces we can get for 90 dollars
$15 $90
-------------- = ----------------
96 ounces x ounces
Using cross multiplication
15x = 90* 96
15x = 8640
Divide each side by 15
15x/15 = 8640/15
x =576 ounces
Now each apple is 5 ounces
576 ounces * 1 apples/5 ounces =576/5 = 115.2 apples
Answer:
389.1 units² (nearest tenth)
Step-by-step explanation:
<u>Regular polygon</u>: all side lengths are equal, all interior angles are equal.
<u>Apothem</u>: a line drawn from the center of any polygon to the midpoint of one of the sides
<u>Radius</u>: a line drawn from the center of the polygon to a vertex.
Therefore, we have been given the apothem of this regular dodecagon.
<h3><u>Formulae</u></h3>
where:
- n = number of sides
- l = length of one side
- a = apothem (the line drawn from the center of any polygon to the midpoint of one of the sides)
where:
- l = length of one side
- n = number of sides
<h3><u>Solution</u></h3>
First, calculate the length of one side of the regular dodecagon by substituting a = 11 and n = 12 into the apothem formula:
Now substitute n = 12, the found value of l, and a = 11 into the area formula:
Heya how has your day been?
