In-s [12.5K]

Answer:

  (A)  125 scoops

  (B)  31 scoops

Step-by-step explanation:

The volume of a cup in terms of radius and height is ...

  V = (1/3)πr²h

The radius is half the diameter, so the volume in terms of diameter is ...

  V = (1/3)π(d/2)²h = (π/12)d²h

The number of cups it takes to empty the sink will be the sink volume divided by the cup volume, so will be ...

  n = (4000π/3)/((π/12)d²h)

  n = 16000/(d²h)

__

(A) The number of cups required of diameter 4 and height 8 is ...

  n = 16000/(4²·8) = 125

  125 scoops are required to empty the sink

__

(B) The number of cups required of diameter 8 and height 8 is ...

  n = 16000/(8²·8) = 31.25 ≈ 31

  31 scoops are required to empty the sink

Answer the following equations:
Andrew [12]

Step-by-step explanation:

3(t+5) = 9

3t+15 = 9

3t = -6

t = -2

2(f-7) = -10

2f - 14 = -10

2f = 4

f = 2

-(c - 9) = 4

-c + 9 = 4

-c = -5

c = 5

-6(2t + 8) = -84

-12t - 48 = -84

-12t = -36

12t = 36

t = 3

-10 (s + 2) = -57

-10s - 20 = -57

-10s = -37

s = 3.7

7(3w + 8)/3 = -9

By cross multiplication,

7(3w + 8) = -27

21w + 56 = -27

21w = -83

w = -3.95

35/5 = (F - 32)/9

7 = (F - 32)/9

By cross multiplication,

63 = F - 32

63 + 32 = F

95 = F

<em>Hope</em><em> </em><em>it</em><em> </em><em>helps</em><em>.</em>
