A woman plans to buy some bottles of alcohol, a bottle of Heineken goes for $800 while that of monster drink $250. she doesn't h

Alja [10]

Answer:

The inequalities that must be satisfied is

$x + y \leq 32$

$x(800) + y(250) \leq 3500$

Step-by-step explanation:

Let the number of Heineken bottles be x

Let the number of monster drink bottles be y

Her crate cannot hold more than 32, This situation can be represented as

$\text{Number of Heineken bottles + number of monster drink bottles } \leq 32$

That is

$x + y \leq 32$ ------------------------(1)

Cost of one Heineken bottles = $800

Cost of one monster drink bottles = $250

then

$x \times \text{cost of one Heineken bottle } + y \times \text{ cost of one monster drink bottle} \leq 3500$ x

$x(800) + y(250) \leq 3500$ ------------------(2)

a car can complete a journey of 300 km with a speed of 60 km per hour I) how much does it take the to complete the journey and w

Verdich [7]

Step-by-step explanation:

First step:

Distance = 300km

Speed = 60km/hr

We know,

Using Speed = Distance ÷ Time

Time = Distance ÷ Speed

we have Total Time = 300÷60

Total Time = 5hr

Again,

Distance = 200km. (Time = 5hr,

Speed =? Distance = 200)

Speed = Distance÷ Time

= 200÷5

= 40km/hr

Factor completely, then place the factors in the proper location on the grid.

grandymaker [24]

Answer:

$(x^n + 2)(x^n + 8)$

Step-by-step explanation:

The polynomial $x^{2n}+10x^n + 16$ can be factored exactly the same as the polynomial $x^2 + 10x + 16$ . Here it factors into two numbers which multiply to 16 but add to 8. These factors are 8 and 2. So it factors into the expression (x+8)(x+2).

For the polynomial $x^{2n}+10x^n + 16$ it factors into the same factors except x ^n is used instead. The factors are $(x^n + 2)(x^n + 8)$

A quality analyst wants to construct a sample mean chart for controlling a packaging process. He knows from past experience that

rosijanka [135]

Using it's concept, it is found that the sample mean package weight for Thursday is of 19 ounces.

The mean of a data-set is given by the <u>sum of the observations divided by the number of observations</u>.

For Thursday, the package weights in ounces are given by: {18, 19, 20, 19}.

Hence, the sample mean in ounces is of:

M = (18 + 19 + 20 + 19)/4 = 19.

Which ordered pair is a solution of the equation?

Marrrta [24]

Answer:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.

Step-by-step explanation:

Given the equation

y = -2x+ 5

<u>Checking the ordered pair (2, -9)</u>

substituting x = 2 and y = -9 in the equation

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1

FALSE!

L.H.S ≠ R.H.S

Thus, the ordered pair (2, -9) is NOT a solution of the equation.

<u>Checking the ordered pair (-2, 9)</u>

substituting x = -2 and y = 9 in the equation

y = -2x + 5

9 = -2(-2) + 5

9 = 4 + 5

9 = 9

TRUE!

L.H.S = R.H.S

Thus, the ordered pair (-2, 9) is a solution of the equation.

Conclusion:

Only (-2, 9) is the solution of the equation.

Hence, option 'b' is correct.
