Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
Multiply both sides of second equation by 20 to get
Subtract that from first equation to get
Divide both sides by 0.7 to get
, so about $428.57 was spent in store. This leaves

Answer:i dont know but hope this helps
Step-by-step explanation:
A straight line is divided into a number of parts with a unit distance between them. By representing a number on a number line, we can easily tell the difference between two numbers and make comparisons between them. It can also be defined as a line on which numbers are marked at a uniform distance.
Answer:
2
Step-by-step explanation:
Given the system of equations:
Comparing 
with the general standard equation of a circle 
.
The first equation is an <u>equation of a circle centred</u> at (0,0) with a Radius of 3.
The second equation 9x+2y=16 is a <u>straight line equation.</u>
A straight line can only intersect a circle at a maximum of 2 points.
Therefore the greatest possible number of solutions to the equations in the system is 2.
