Answer:
The required expression is 
Step-by-step explanation:
Consider the provided information.
A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.
Steps to write a number in scientific notation.
- Move the decimal place to the right so that the new number from 1 up to 10.
- Determine the exponent, the exponent is the number of times you moved the decimal.
Now, consider the number 0.000075
Move the decimal point to 5 place right so that the new number from 1 up to 10.
Now, put the exponent the number of times you moved decimal.
Hence, the required expression is
$1400 / 7 = $200
$200 x 2 = $400
$1400 - $400 = $1000
John has $1000 left in his account.
Answer:
+ 3
Step-by-step explanation:
For this case we can use the law of the sine to solve the problem.
We have then:
From here, we clear the value of x.
We have then:
Rewriting we have:
Answer:
The angle R is given by:
