Answer:

\dfrac{30x}{24}>\dfrac{450}{24}

Step-by-step explanation:

We are given the following in the question:

Let x be the total number of sparkling cans of water used in a day.

The family uses more than 15 cans each day so inequality becomes,

x > 15

Number of cans in 30 days

30x > 450

The family buys case of water with 24 cans in each case.

Number of cans used in a day is more than 15, so approx number of cans used in 30 days will be =

\dfrac{30x}{24}>\dfrac{450}{24}\\\\\Rightarrow \dfrac{30x}{24}>\dfrac{450}{24} = 18.75 \approx 19\\\\\text{Number of cases} > 19

Thus, the family buys around 19 cases or more of sparkling water in 30 days.

which function rule is represented by the tablex 0 1 2 3y 0 -7 -14 -21a y= 7xb y= -7xc y= x-8d y= 7x-14
salantis [7]

The answer is y = -7x

Expalnation

Two points on the table are (0,0) and (1,-7)

Change in y = -7-0 = -7

Change in x = 1-0 = 1

Slope m of the function = -7/1= -7

Using y= mx + c

Picking point (0,0), x = 0, y = 0

y = mx + c becomes

0 = -7(0) + c

0 = 0 + c

c= 0

Hence, the equation is y = -7x + 0

which is y = -7x

Option b is the correct answer

T. The entropy change As, for an ideal gas is given by the following formula: dT dV As=1C [c. R T V 7 where T is the thermodynam
MissTica

Answer:

The entropy change AS, for an ideal gas is given by: dt V Where T is the thermodynamic temperature, V is the volume and R=8.314. Determine the entropy change when a gas expands from 1 litre to 3 litres for a temperature rise from 100K to 400K given that: Cv = 45 + 6 x 10-T + 8 x 10-6T2 b) The average value of a complex voltage waveform is given by: V = ( 10 (10sin ox +3sin 30x +2 sin 508) dt Evaluate Vav correct to 2 decimal places.
