(50 points worth ) A rectangular prism fish tank a length of 5 1/2 in., a width of 7 in., and a height of 2 1/2 in. Use this to
densk [106]
A) What's the volume of this fish tank? Show all work and express your answer as a mixed number in its most simplified form!
 By definition we have that the volume of a rectangular prism is given by:
 V = (w) * (l) * (h)
 Where,
 w: width
 l: long
 h: height
 We then have to replace the values:
 V = (7) * (5.5) * (2.5)
 V = 96.25 in ^ 3
 Equivalently:
 V = 96 1/4 in ^ 3


 B) Could this fish tank hold 100 in³ of water? Answer yes or no, then explain why in one or more sentences.

 No, this fish tank could not hold 100 in³ of water.
 This is because the prism volume (part A) is less than 100 in ^ 3.
 In other words;
 96 1/4 in ^ 3 <100 in ^ 3

What is the volume of the rectangular prism?<br> 1/3ft
IrinaVladis [17]
We know that 1 cube equals 1/3. If you count the rectangular prism, you learn that there are 30 cubes in total that make up the rectangular prism. So what I did was 1/3 times 30. You could also divided 1 by 3, and get 0.3333333333, which is equal to 1/3 (1/3 = 0.3333333333) So, you should come out with ten. Thus your answer would be D, 10ft cubed.


Hope this helps :)

Minimize Q=3x2+3y2​, where x+y=6.
weeeeeb [17]

Answer:

+(x + y) {}^{2}  = 6 {}^{2} \\ x {}^{2} + 2xy + y {?}^{2}  = 36

x {}^{2}  + y {}^{2}  = 36 - 2xy

q = 3(x {}^{2}  + y {}^{2} )

q = 3(36 - 2xy) = 108 - 6xy
