The variable z is directly proportional to x, and inversely proportional to y. When x is 14 and y is 10, z has the value 26.6.

AysviL [449]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in one variable will cause a corresponding increase in the other variable.

If two variables are inversely proportional, it means that an increase in one variable will cause a corresponding decrease in the other variable.

The variable z is directly proportional to x, and inversely proportional to y. If we introduce a constant k, the equation would be

z = kx/y

When x is 14 and y is 10, z has the value 26.6. It means that

26.6 = 14k/10

Cross multiplying, it becomes

26.6 × 10 = 14k

266 = 14k

k = 266/14

k = 19

The equation becomes

z = 19x/y

When x = 24, and y = 15, the value of z would be

z = 19 × 24/15

z = 30.4

There is an unknown number •it is a four digit number •the tens are double the ones •the thousands are double the tens •the sum

oksano4ka [1.4K]

Answer:

8542

Statement

1.It is a four digit number

2.The tens are double the ones

3.The thousands are double the tens

4.The sum of the digits is nineteen

Step-by-step explanation:

It is a four digit number

lets take 4 digit number-ABCD

The tens are double the ones

$C=2D$ -----------------------------1

The thousands are double the tens

$A=2C$ -------------------------------2

According to equation 1 and 2

$A=4D$

If we take

$D=1,2$

Possible number

$4B21$ OR $8B42$

The sum of the digits is nineteen

I use hit and trial method

$4B21$ - If I take B is maximum

$4+9+2+1\neq 19$

$8B42$ - If, i try to find value of B

$8+B+4+2=19$ ---------------------3

$14+B=19\\B=19-14\\B=5$

So the unknown number is- 8542
