Answer:
Sum = 2,340°
Step-by-step explanation:
Sum of interior angles = 180·(n-2),
where n is the number of sides the polygon has
Sum = 180·(15-2)
Sum = 180·13
Sum = 2,340°
Answer:
Linear relationship
Step-by-step explanation:
This is a linear relationship as it is expressed in the form y= mx+b
Here y= n b = -6 and x= m
A linear equation corresponds to a straight line hence it shows a linear relationship.
There is a correspondence between algebra and geometry through co ordinate system. We can convert a point into a pair of numbers and vice versa.
If we are given the value of y we can determine x and vice versa.
n = 4m – 6
In the given equation suppose x = 5 so y will be 14
n= 4(5)- 6
n= 20-6= 14
Also if we have y= 18 x will be 6
n = 4m – 6
18 + 6= 4m
24/4= m
m= 6
Answer:
In this scenario you should use chefs if you have less than 55 people and you should use cece's if you have more than 55 people.
Step-by-step explanation:
To find out which one will be cheaper you need to know where they intersect, to do this you need to set up a system of equations.
y=28x+590 (chefs)
y=31x+425 (cece's)
to know where they intersect you need to make the y=0
28x+590=31x+425
Then solve
subtract the x from each side
590=3x+425
Subtract 425 from each side
3x=165
divide each side by three
x=55
now evaluate
Place a number above 55 (60 for example) into the place of x
28(60)+590=2,270
31(60)+425=2,285
In this scenario you should use chefs if you have less than 55 people and you should use cece's if you have more than 55 people.
