son4ous [18]3 years ago

Answer:

12 possible outcomes

Step-by-step explanation:

If she's spinning them at the same time, this is how you do it:

There are 3 possible outcomes on the first spinner- Walk, Run, and Stop.

There are 4 outcomes on the second spinner- Red, Green, Blue, and Orange.

Since they're being spun at the same time, we need to consider all of the possible combinations, for example:

Walk & Red.

Walk & Green.

Walk & Blue.

Walk & Orange.

And so on.  Each outcome on the first gets multiplied by 4, since there are 4 sections on the 2nd spinner.  Same thing if you did it and switched- the 4 sections on the second spinner would each have 3 different outcomes.

In conclusion, you'd just multiply 3×4, and there you go.  Or, you can think of it as 4+4+4, if that's a little easier to understand.

Twice Sam's age added to half her mother's age is 48. Three times her age less one third of her
yan [13]

Answer:

Sam is 15 and her mother is 36

Step-by-step explanation:

Let Sam's age be x and her mother's age by y

We can figure out Sam and her mother's age by representing these scenarios using equations with variables and solving the system using elimination

2x+y/2=48

3x-1/3y=33

You start by making all the numbers in both the equations whole

2(2x+y/2=48)

3(3x-1/3y=33)

Becomes:

4x+y=96

9x-y=99

Add together to eliminate y

13x/13=195/13

x=15

Now that we have x we can plug the value into the x in the equations to give us the y-value

2x15+y/2=48

30+y/2=48

30+y/2-30=48-30

y/2=18

2 X y/2=18 X 2

y=36

Therefore x=15 and y=36

V = 2 - F + E
V = 2 - 12 + 18 
V = 8

(a) </span><span>12 faces, 18 edges, <u>8</u> vertices

<u>Question b:</u>

</span>V + F - E = 2
<span>E = V+ F - 2
E = 14 + 8 - 2
E = 20
