Answer:
R7,200
Step-by-step explanation:
We find the new salary by multiplying the old salary by 20% and adding this value to the old salary.
Thus, we have 6,000 + (6,000 * 0.20) = 6,000 + 1,200 = R7,200
Hello!
The fraction is an improper fraction (the numerator is greater than the denominator). The whole number part of the mixed number is found by dividing the 24 by the 9. The fractional part of the mixed number is found by using the remainder of the division, which in this case is 6 (24 divided by 9 is 2 remainder 6).
Answer:
(x+3)^2+(y+5)^2=169 with a radius of 13
Step-by-step explanation:
honestly, I used wolfram alpha and it was able to find the radius form the center and the point it was passing through. I dont rember the work for this lol
Let
x-------> the length side of the poster
y-------> the width side of the poster
we know that
Area of the poster is equal to
-------> equation 
Area of the printed area is equal to
----> equation 
substitute equation in equation
![Aprinted=[210]-3x-2*[\frac{210}{x}]+6](https://tex.z-dn.net/?f=%20Aprinted%3D%5B210%5D-3x-2%2A%5B%5Cfrac%7B210%7D%7Bx%7D%5D%2B6%20%20)
using a graph tool
Find the vertex of the graph
The vertex of the graph is the point that represent the value of x for the largest printed area
see the attached figure
the vertex is the point 
the largest printed area is 
find the value of y
therefore
the answer is
The dimensions of the poster are
