If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.

Leto [7]

Answer:

y = 6

Step-by-step explanation:

If x varies inversely proportional as y.

$x=\dfrac{k}{y}$ , k is constant of proportionality

k = xy

When x = 3 and y = 10

k = 3×10

k = 30

Put x = 5,

$y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6$

So, the value of y is 6 when x is 5.

A farmer has 7 3/4 rows of radishes in one field, 4 3/4 rows of radishes in another field, and 6 1/4 rows of radishes in a third

Gala2k [10]

Answer:

A. 18 3/4

Step-by-step explanation:

It is convenient to rearrange the sum to make it easier to compute:

7 3/4 + 4 3/4 + 6 1/4 = (7 3/4) +(4 +6) +(3/4 +1/4)

= 7 3/4 + 10 + 1

= 18 3/4

The farmer has 18 3/4 rows of radishes altogether.

Tony is making new numbers

KonstantinChe [14]

Answer:

The biggest number he can make is 348. Hope this helps!!!

Step-by-step explanation:

You have to multiply 4 and 7 together to get 28. Since if we multiplied every number together, we would end up with a lesser number, since anything multiplied by 1 is itself. Therefore, you next add 1 to 28 to get 29. Finally multiply 29 by 12 to get 348.
