Answer:
Jeff's Popcorn 130^3
Step-by-step explanation
(Jeff's 130^3) .
First 20.5*10^2 which is 20.5*100 which equals 2050.
Then find the volume for the other box of popcorn.
30*8^2 which is 1920.
subtract 2050 by 1920 and you get 130.
Answer: 9 1/3 - 2/3 = 8 2/3 .
___________________________________
Note: If the answer were "8 1/3" ;
then: "8 1/3 + 2/3 =? 9 1/3 ? "
→ "8 1/3 + 2/3 = 8 3/3 = 8 + 1 = 9 = only "9" ;
____________________________________________
So the answer has to be MORE than "8 1/3"
Try "8 2/3" → "8 2/3 + 2/3 =? 9 1/3?" ?? ;
→ "8 2/3 + 2/3 = 8 4/3 = 8 + 1 1/3 = 9 1/3 " → Yes!
_________________________________________________
So, the answer is: "8 2/3" .
_________________________________________________
Another method:
_________________
Given the problem: "<span>9 1/3 - 2/3 " ;
___________________________________
Note that: "2/3 = 1/3 + 1/3"
__________________________________
So, "</span><span>9 1/3 - 2/3 = 9 1/3 - (1/3 + 1/3) = 9 1/3 - 1/3 - 1/3 = ?
________________________________________________
Start with: "</span>9 1/3 - 2/3" = 9. Then 9 - 1/3 = 8 3/3 - 1/3 = 8 2/3.
<span>______________________________________________________
</span>Another method:
____________________________
Given the problem:
____________________________
"9 1/3 - 2/3 = ?? " ;
____________________________
Convert "9 1/3" into "28/3" ; ("3*9 = 27"); ("27+1=28");
(The "3" comes from the "3" in the: "1/3" portion.)
_________________________________________________________
So, we rewrite as:
_____________________________________
28/3 - 2/3 = (28 - 2) / 3 = 26/3 ; or, 8 2/3 .

Answer:
B. x=5, y=4
Step-by-step explanation:
the tiny triangle is 3x smaller so just divide those numbers by three
Answer: hello your question is incomplete attached below is the complete question
answer :
a)
( option D )
b) A = 1/2 (6)(3) ( option B )
c) Area of shaded region = 9
Step-by-step explanation:
<u>a) Using integration with respect to x </u>
Area =
( note a = 10 )
= y^2/2 - 4y |⁷₄ + 10y - y^2/2 |¹⁰₇
= 33/2 - 12 + 30 - 51/2 = 9
hence the best integral from the options attached is option D

= [ 10x - x^2 /2 - x^2/2 - 9x ] ³₀
= 30 - 9/2 - 9/2 - 12 = 9
<u>b) Using Geometry </u>
Area = 1/2 * base * height
= 1/2 * 6 * 3
= 9
