Since the surface area of a prism is
A = 2lw + 2lh + 2wh
then the surface of the 1/3 scale key chain will be:
A = 2( l / 3 )( w / 3 ) + 2 ( l / 3 )( h / 3 ) + 2( w / 3 )( h / 3)
A = (2/9) ( lw ) + ( 2 / 9 ) ( lh ) + ( 2/9 ) ( wh)
A = ( 1 / 9 ) ( lw + 2lh + 2wh)
so the ratio <span>of the key chain to the book is 1/9</span>

Strange question to me
![P\approx0.90](https://tex.z-dn.net/?f=P%5Capprox0.90)
1) The first thing we need to do is to find the total number of visitors. This is going to be our Sample Space
31+26+2=31+28=59 Visitors altogether
2) The next thing to do is to find the favorable event. Note that we can see that 26 people purchased only one costume.
3) The final and last step is to find the probability, so we can write out the following:
![P=\frac{26}{59}=0.8965\approx0.90](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B26%7D%7B59%7D%3D0.8965%5Capprox0.90)
Thus, this is the answer: 0.90

Answer:
c. 19
Step-by-step explanation:
You must find everyone's age.
Toni is 21 and Toni's age plus Maria's age is 36. so 36-21= 15.
This tells us that Maria is 15.
Jacob's age plus Maria's age is 29. to find Jacobs age we need to subtract Maria's age from 29, 29-15 is 14.
Maria is 15,
Jacob is 14,
and Toni is 21.
Jacobs age plus marcels age is 33, so now we need to subtract Jacobs age to 33. 33-14 = 19
Marcel is 19 years old.
I hope this wasn't confusing and it helped. Have a good day.
