Mack designed a water fountain with a square pyramid flowing into a cube. The edges of the bases of the pyramid and the cube have the same length and the heights of the pyramid and the cube are the same. Describe the relationship between the volume of the cube and the volume of the pyramid.

Please help me on this question. There are six questions in total and I did the rest (finding the volume/surface area) but this one I just don't understand. I'm willing to give up 60 of the 70 points I have for help (help that tells me the answer and explains it). Maybe even all 70. Please help if you understand. Thank you, minna.

Answers

volume of pyramid = 1/3 b2h
volume of  cube = b3

now , provided pyramid and cube have same edges and same heights.

thus, volume of pyramid = 1/3 b3
volume of cube = b3.

thus, ratio = 1/3b3/ b3 = 1/3.

Thus, volume of pyramid = 1/3volume of cube
V_(cube)=a^3\ \ \ and\ \ \ V_(pyramid)= (1)/(3) \cdot a^2\cdot h=(1)/(3)a^3\n \n (V_(pyramid))/(V_(cube)) = ((1)/(3)a^3)/(a^3)= (1)/(3)\n \n \nA_(cube)=6a^2\n \nh^2=a^2+( (1)/(2) a)^2\ \ \ \Rightarrow\ \ \ h^2= (5a^2)/(4)\ \ \ \Rightarrow\ \ \ h= (a √(5) )/(2)\n\nA_(pyramid)=a^2+4\cdot (1)/(2)ah=a^2+2a\cdot (a √(5) )/(2) =a^2(1+ √(5)) \n \n (A_(pyramid))/(A_(cube))= (a^2(1+ √(5)) )/(6a^2) = (1+ √(5))/(6)

Sandy has several pitchers to hold lemonade for the school bake sale.Two pitchers can hold 64 ounces each,and four pitchers can hold 48 ounces each.How many total ounces can sandy's pitchers hold? SHOW YOUR WORK TO EARN 8POINTS

Answers

We know that there are 2 pitcher of 64 ounces and 4 pitcher of 48 ounces.
To find how ounces Sandy's pitcher holds, we must do:
(64×2)+(48×4)=Total amount of lemonade
128+192=320 ounces
So, Sandy has 320 ounces of lemonade.

Final answer:

Sandy's pitchers can hold a total of 320 ounces of lemonade. This is calculated by multiplying the number of pitchers by the ounces each can hold, and then adding the totals for each group of pitchers.

Explanation:

To find the total amount of lemonade Sandy's pitchers can hold, you first need to calculate how much each group of pitchers can hold. Two pitchers can hold 64 ounces each, so for these two pitchers, the calculation is 2 pitchers * 64 ounces/pitcher = 128 ounces.

Similarly, four pitchers can hold 48 ounces each. So, for these four pitchers, the calculation is 4 pitchers * 48 ounces/pitcher = 192 ounces.

Finally, to find the total amount of ounces all pitchers can hold, you add the totals from each group of pitchers. The calculation is 128 ounces + 192 ounces = 320 ounces. Therefore, Sandy's pitchers can hold a total of 320 ounces of lemonade.

3x+y=15 5x-4y=8

resolucion de sistema por el metodo de sustitucion

Answers

Answer:

x=4

y=3

Step-by-step explanation:

we have the following equations

3x+y=15  equation 1

5x-4y=8  equation 2

using equation 1 we have:

y=15-3x equation 3

using equation 3 in equation 2 we have:

5x-4(15-3x)=8

5x-4*15+4*3x =8

5x-60+12x = 8

17x=68

x=68/17

so we have x=4

finally in equation 3:

y = 15-3(4)

y = 15-12

y = 3
