To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.
3 / 500 = 0.006
So our percentage of defective batteries is 0.6%.
Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.
12000 * 0.006 = 72
In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.

Answer: I think the length is 60.25 yd and the width is 19.75 yd
Step-by-step explanation: I formed a equation using the information that has been given.
Width : X
length : 1 + 3x
equation : (1 + 3x) + x = 80
Then, I added the like pairs ( 3x+x ). After, I subtracted 1 from 80 and got 79. Then I divided 79 and 4 (79/4) to get 19.75, which is my x value. later, I substituted the x value to the equation and received my answer.
The area of the flag that Joe created is 216 cm²
Step-by-step explanation:
Joe created triangular shaped flag for his history project
- The height of the flag was 16 cm
- The base of the flag was 27 cm
∵ The flag is shaped a triangle
∵ Area of a triangle = 
× base × height
∵ The base of the flag = 27 cm
∵ The height of the flag = 16 cm
- Substitute these values in the rule of the area above
∴ The area of the flag = × 27 × 16
∴ The area of the flag = 216 cm²
The area of the flag that Joe created is 216 cm²
