Answer: 5.6

Step-by-step explanation:

Da loooong division:

move the decimal over 1 and add a 0 to the 14 (because you moved the decimal)

25/140

25 goes into 140 5 times. 5 * 25 = 125.

140 - 125 = 15

add a 0 (because 25 doesnt go into 15)

25 goes into 150 6 times.

6 * 25 = 150

150 - 150 = 0.

You put the decimal back into the answer (right after the 5, before the 6)

Find the constant of variation for the relation and use it to write and solve the equation.

Ksenya-84 [330]

Answer:

When x = 1 and z = 4, $y=\frac{80}{9}$

Step-by-step explanation:

The variation described in the problem can be written using a constant of proportionality "b" as:

$y=b\,\,x\,\,z^2$

The other piece of information is that when x = 5 and z = 1, then y gives 25/9. So we use this info to find the constant "b":

$y=b\,\,x\,\,z^2\\\frac{25}{9} =b\,\,(5)\,\,(1)^2\\\frac{25}{9} =b\,\,(5)\\b=\frac{5}{9}$

Knowing this constant, we can find the value of y when x=1 and z=4 as:

$y=b\,\,x\,\,z^2\\y=\frac{5}{9} \,\,x\,\,z^2\\y=\frac{5}{9} \,\,(1)\,\,(4)^2\\y=\frac{5*16}{9}\\y=\frac{80}{9}$
