Answer:

Step-by-step explanation:
Given voltage of primary coil is 
And voltage of secondary coil is 
A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil
and secondary coil
.
Following equation represents the relation between them.

Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is

0.000000000093 in scientific notation is 9.3 x 10 ^ -11
The final cost depends on the amount he buys since the 16.99 is the constant. Equation form is 16.99n where n is the amount hence the inconsistent variable
Answer: 220 yards
Step-by-step explanation:
1 mile equals 1,760 yards
1,760 ÷ 8 = 220 yards
8/8 is 1... so that 1 is equal to the 1,760
You could divide it by 8 as shown above OR to double check yourself.. take your answer of 220 yards and add that 220 to 220 a total of 8 times which will give you your 1 mile equaling to 1,760 total yards which makes 1/8 mile equal the 220 yards. (I really hope this helps and makes sense as to how I figured that out for you:-) )
