Answer: 1600batteries
Step-by-step explanation:
Let the number of inspected battery be y
2.5% of y = 40
5/2% of y = 40
Change 5/2% to fraction
5/200 × y = 40
5y/200=40
Cross multiply
5y= 40×200
5y=8000
y=8000÷5
y=1600
The total number of battery inspected is 1600.

Answer:
9 & 6
Step-by-step explanation:
First, check if, by adding them (sum), they equal 15:
9 + 6 = 15
Next, check the greater number, by multiplying it by 2:
9 x 2 = 18
Check the lesser number, by multiplying it by 3:
6 x 3 = 18
Note that they both have 18 as an answer.
9 & 6 are your answers.

Explanation:
The heights of the trees are directly proportional to the length of their shadows because at the same time of day, the sun will be at the same angle in the sky.
The trees and their shadows form 2 similar triangles:
Write as a proportion:
<span><span>heightshadow</span> <span>x20</span>=<span>1512</span></span>
<span>12x=20×15</span>
<span>x=<span><span>20×15</span>12</span></span>
<span>x=25</span> metres tall.
As check: find the constant for each tree:
<span><span>1512</span>=1.25 and <span>2520</span>=<span>1.25</span></span>
