Step-by-step explanation:
if we tip/tax 6% of 156.67 we will do:
156.67*(6/100)=9.40 this is the amount of tip
156.67+9.40=166.07
Answer: 40 people
Step-by-step explanation:
There were 5 pies in the party and each person that came got an equal share of 1/8.
The number of people who were there is therefore:
= Number of pies / Share each person got
= 5 ÷ 1/8
= 5 * 8/1
= 40 people

Answer:
9*sqrt(2) (third in your list of answer)
Step-by-step explanation:
Lets indicate the vertices with the letters beginning the upper vertice A next clockwise B and finally C (right angle)
Angle C=45 degrees. ANgle C is 90 degrees ( small square on the diagram means 90 degrees) So the angle A= 180-90-45=45 degrees.
Angle A=angle C=45 degrees=> AC=CB=9
Using Phitagor theorem will get AB= sqrt(AC^2+BC^2)=sqrt(81+81)=9*sqrt(2)
