**Step-by-step explanation:**

i hope this helps its kind of hard to see but i tried lol

**Answer:**

5

**Step-by-step explanation:**

Assuming both players can answer the same question, the minimum number of questions is **the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.**

Let x be the number of questions, solving by trial and error:

**Therefore, the minimum number of questions in the game is 5.**

**Answer:**

It would be...

**Step-by-step explanation:**

Similar By: 22.5 and 27

ABCD: G AND H AND F

I am not sure but I try hard

So we set it up like beofre

c=number of calzones

s=number of slices

total of 59 so

c+s=59

total money was 456

9c+6s=456

we can divide both sides by 3 to simplify

3c+2s=152

use subsitution

c+s=59

minus s both sides

c=59-s

subsitute 59-s for c in other equation

3c+2s=152

3(59-s)+2s=152

177-3s+2s=152

177-s=152

minus 177 both sides

-s=-25

s=25

sub back

c=59-s

c=59-25

c=34

34 calzones

25 slices

**Answer:**

**Step-by-step explanation:**

- Amount of radioactive material = 576 grams
- Half-life = 64 hours
- Time = 256 hours

<u>Cycles of reduction:</u>

<u>Material will be left:</u>

- 576*(1/2)^4 =
- 576*1/16 =
**36 grams**
