How many are there then the total amount
Answer:
10% off would be $96.94
So using the Coupon for 10% off would be the best deal.
Irrational roots occurs with its conjugate.
Therefore, -√3 is also root of the function.
The answer is -√3.
Answer:
$153
Step-by-step explanation:
To find the total cost, we have to calculate the area of one bead, then all of them:
Area of one bead = pi x r^2 = 3.14 x 0.5^2 = 3.14 x 0.25 = 0.765cm^2
Area of 20 beads = 0.765 x 20 = 15.3cm^2
Now, we are able to calculate the ultimate cost of coating:
If the cost is $10 per cm^2, then we have to find how much it costs to coat 15.3 cm^2.
15.3 x 10 = $153.
Hope this helps
