Y is inversely proportional to a^3

Mathematics
1 answer:
Ludmilka [50]3 years ago
6 0

Answer:

y = 0.64/x^3

Step-by-step explanation:

If y is inversely proportional to a^3, we can write the equation:

y * a^3 = k

Using a = 2 and y = 10, we have:

10 * 2^3 = k

k = 80

If a is directly proportional to x, we can write the equation:

a = c * x

Using x = 4 and a = 20, we have:

20 = c * 4

c = 5

Now, using the value of a = 5*x in the equation y * a^3 = 80, we have:

y * (5x)^3 = 80

y * 125x3 = 80

y = 80/(125x3) = 0.64/x^3

  • 3.5 : 3.5 + 2
  • 3.5 : 5.5
  • 3.5 x 2 = : 5.5 x 2
  • 7 : 11

Multiply the ratio into the amount paid :

  • 52.25 x 7/11
  • 4.75 x 7
  • <u>$33.25</u>

<u></u>

Eric's share of the money is <u>$33.25</u>

Can someone please help me out<br> ASAP I WILL GIVE OUT BRAINLY
SashulF [63]

Answer:

x = 9

Perimeter = 74

Area = 342

Step-by-step explanation:

First, find x. to do so, set your formula up as

18 = 8x - 54

18 + 54 = 8x

72 = 8x

72/8 = x

9 = x

Now that you have x, find your missing side

2x + 1 = y, x

2 * 9 + = y

19 = y

Your perimeter is P = 2(l+W)

P = 2(18 * 19)

P = 74

Your area is A = wl

A = 19 * 18

A = 342
