18

Step-by-step explanation:

3 meats * 3 veges* 2 desserts =

3 *3*2 = 18 different ways

18

Step-by-step explanation:

Let's label the meat A₁, A₂, and A₃

Vegetables B₁, B₂, and B₃

Desserts C₁ and C₂

Now just make as many ways you can

A₁ B₁ C₁

A₁ B₂ C₁

A₁ B₃ C₁

A₁ B₁ C₂

A₁ B₂ C₂

A₁ B₃ C₂

That's all of the A₁s

Now it's going to be the same fore A₂ and A₃

Since there are 6 in A₁, there'll be 6 in A₂ and 6 in A₃

Now that's 18

The mathematical way would be using the counting principle

So 3*3*2 = 18

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
