Answer:

7

Step-by-step explanation:

6x6=36

7x6=42

8x6=48

36-9=25 thus it isn't possible because it's not between 31 and 37. 48-9=39 hence also not possible. However for 42, it is defintely possible. Thus answer is 7

Totally going on a limb and answering this right now for the fun, but really hoping to help. So multiples of 6. If you start at 6(6)=36. 9 less than 36 isn’t between 31 & 37. However, when you go to 6(7)=42, 9 less than 42 is 33 and 33 does indeed lie between 31 & 37. My final answer would be 33.

What is the probability that both of Eduardo's partners for the group project will be girls? StartFraction 9 Over 65 EndFraction
tester [92]

Answer:

StartFraction 24 Over 65 EndFraction

Step-by-step explanation:

Total number of students = 26

Number of boys = 10

Number of girls = 26-10

=16

Eduardo has to pull two names out of the hat without replacing them.

First name

Probability= Favourable outcome/Total outcome

Probability of girls=16

Total probability=26

Eduardo has to pull two names out of the hat without replacing them.

Probability= Favourable outcome/Total outcome

=16/26

=8/13

For the second name:

Without replacement of the first hat

Probability of girls=16-1=15

Total probability=26-1=25

Probability= Favourable outcome/Total outcome

=15/25

=3/5

Probability of both of Eduardo's partner for the group project will be girls=8/13*3/5

=24/65

Step-by-step explanation:

AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.

What is the perimeter of quadrilateral ABCD with verticals at A(-11,-6) b(-3,0) c(1,0) and d (1,-6)
dedylja [7]

<u>Answer:</u>

32 units

<u>Step-by-step explanation:</u>

We have a quadrilateral ABCD and we are given the following coordinates for these vertices:

A (-11,-6)

B (-3,0)

C (1,0)

D (1,-6)

AB = \sqrt{(0-(-6))^2+(-3-(-11)^2} = \sqrt{36+64} =\sqrt{100} = 10 units

BC = \sqrt{(0-0)^2+(1-(-3)^2} = \sqrt{0+16} =\sqrt{16} = 4 units

CD = \sqrt{(0-(-6))^2+(1-1^2} = \sqrt{36+0} =\sqrt{36} = 6 units

AD = \sqrt{(-6-(-6))^2+(1-(-11)^2} = \sqrt{0+144} =\sqrt{144} = 12 units

Perimeter of ABCD = 10+4+6+12 = 32 units
