Abigail shows up at a restaurant that has 30 tables. 12 of them are booths and 18 of them are tables with chairs. What is the probability that she is seated at a booth?

Question 5 options:

60%

40%

18%

12%

40%

Step-by-step explanation:The probability to be seated in a booth is 12/30.So this chances of not siting in a booth is 18/30.To find the percent yu have to find the part of 30.For example,60 times 60% is 18 then you subtract that by 100.100 subtract 60 equals 40.

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
