Relative to the ground Emma's velocity is 50 m/s + 1 m/s =
Answer: 51 m/s
We don't use that other equation.
Answer: 
Step-by-step explanation:
For this exercise you need to remember that a Square is defined as a Quadrilateral whose sides are equal in lenght and all its interios angles measure 90 degrees.
Based on that definition, and observing the squarE given in the picture attached, you can write the following equation:

Then, you need to solve for the variable "x" in order to find its value. You get that this is:

Now, knowing the value of "x" you can susbstitute it into any expression that represents the side of the square, and then you must evaluate in order to find the lenght of the side.
You get:

Answer:
Step-by-step explanation:
hello :
y = 4x - 5 means : 4x-y=5
y - 3 = 5(4-X) equivalent : y-3 = 20 -5x means : 5x+y =23
Answer:
$85.174
Step-by-step explanation:
Data provided in the question;
Treasury bond = $2000
Interest rate = 3.7%
Quoted at 115.1 points or 1.151%
Therefore,
the price of the bond = 1.151 × $2000
or
the price of the bond = $2,302
Thus,
the annual interest = Price of the bond × rate
or
the price of the bond = $2,302 × 0.037 = $85.174
Hence, the annual interest in $85.174
