Answer:

(n/4)-1

Step-by-step explanation:

total slices = n

total number of people =4

each people may be eat = n/4 slices

here Harris eats 1 slice fewer

then Harris eats (n/4)-1 slices

hope this helps you

MrRa [10]

Answer:

  • ength (l) : (10-2*5/3) = 20/3
  • width(w): (10 - 2*5/3) = 20/3
  • height(h): 5/3

Step-by-step explanation:

Let x is the side of identical squares

By cutting out identical squares from each corner and bending up the resulting flaps, the dimension are:

  • length (l) : (10-2x)
  • width(w): (10-2x)
  • height(h): x

The volume will be:

V = (10-2x) (10-2x) x

<=> V = (10x-2x^{2}) (10-2x)

<=> V = 100x -20x^{2} - 20x^{2} + 4x^{3}

<=> V = 4x^{3}  - 40x^{2} + 100x

To determine the dimensions of the largest box that can be made, we need to use the derivative and and set it to zero for the maximum volume

dV/dx = 12x^{2} -80x + 100

<=>  12x^{2} -80x + 100 =0

<=> x = 5 or x= 5/3  

You know 'x' cannot be 5 , because if  we cut 5 inch squares out of the original square, the length and the width will be 0. So we take x = 5/3

=>

  • length (l) : (10-2*5/3) = 20/3
  • width(w): (10 - 2*5/3) = 20/3
  • height(h): 5/3

Y=25000(1-0.63)^2<br> Find the decay rate.
Anestetic [448]

If I'm not mistaken.. the half-life should be 40,750 years.. so

y = 40,750


I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get

20,375.. so one of those should be correct

Which two rooms have an
alexgriva [62]

Answer: room 101 and room 107

Step-by-step explanation:

In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3

In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.

In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3

Therefore, room 101 and room 107 have the same ratio.

Solve for x<br> (-4/3) x - 6 = -26<br><br> A. −27<br> B. −15<br> C. 15<br> D. 27
andre [41]
- \dfrac{4}{3} x - 6 = -26

//Add 6 to both sides:
- \dfrac{4}{3} x  = -20

//Multiply by -1 on both sides:
\dfrac{4}{3} x  = 20

Multiply by 3 on both sides:
4x  = 60

Divide by 4 on both sides:
x  = 15

-----------------------------------------
Answer: x = 15 (Answer C)
