We have to write number 4 in different places in ones, tenths,hundredths, and thousandths.
So, numbers are = 4.000 , 0.004 , 0.040 , 0.400
The statements can be like =
In 4.000 , the 4 is in ones place.
In 0.400, the 4 is at tenth place.
In 0.040 , the 4 is at hundredth place.
In 0.004 , the 4 is at thousandth place.
<h3>
Dan's equation is wrong.</h3>
Step-by-step explanation:
Given, Dan borrows money to buy a new trumpet $400 at simple interest rate of 5% .
here P =$400, r = 5% and t = 1


Therefore he will need to pay back after one year is = 400+(0.05×400)
So, t = 400+(0.05×400)
Dan's equation is wrong.
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
