If y varies directly with x, find the value of y when x = 27 for the direct variation with the given information. y = 7 when x =
ElenaW [278]

Given:

y varies directly with x,

It is given that y = 7 when x = -9.

To find:

The value of y when x = 27 for the direct variation.

Solution:

It is given that y varies directly with x, so

y\propto x

y=kx             ...(i)

Where, k is the constant of proportionality.

It is given that y = 7 when x = -9. Putting these values in (i), we get

7=k(-9)

-\dfrac{7}{9}=k

Putting k=-\dfrac{7}{9} in (i), we get

y=-\dfrac{7}{9}x

Putting x=27,  we get

y=-\dfrac{7}{9}(27)

y=-21

Therefore, the required value is y=-21.

Help me with this please
borishaifa [10]

Answer:

11/60

Step-by-step explanation:

sin x = opp/hyp

cos x = adj/hyp

tan x = opp/adj = (opp/hyp)/(adj/hyp)

tan x = (11/61)/(60/61)

tan x = 11/61 * 61/60

tan x = 11/60

How do you simplify 3:9:15:24
vovikov84 [41]
All of those numbers have a common factor, which is 3. So you divide all of their values by 3.

3:9:15:24
=1:3:5:8

Because the values cannot be divided anymore, this ratio is in it's simplest form.
