A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==

Barbara is deciding between Banquet Chefs and CeCe's Catering to cater an awards banquet. Barbara needs to choose the company th
zmey [24]

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.
