12 divided by 8/9 = ?

Mathematics

Oduvanchick [21]3 years ago

The answer would be 13 1/2 because you turn the 12 into a fraction then change the division sign into a multiplication sign and find the reciprocal of 8/9 which is 9/8 you could now divide 12/1 divided by 9/8 you could cross simply then dove to get 27/2 and in the end you get 13 1/2 if you turn the improper fraction into a mixed number.

Solve the following maximization problem graphically.
rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

P(x,y) = 11x + 10y

<h3>Constraints</h3>

The constraints are given as:

22x + 2y \le 68

8x + 16y \le 68

x,y\ge 0

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

P(x,y) = 11x + 10y

P =11 \times 2.833 + 10 \times 2.833

P =59.493

Approximate

P =59.5

Rewrite as a fraction

P =\frac{119}{2}

Hence, the maximized value of the function is (c) 119/2

LAST ONE I SWEAR BUT STILL WILL MARK BRAINLIEST
Pavel [41]

Answer:

a. 8x + 4y = −4

17x + 2y = −28

Step-by-step explanation:

{6x + 2y = −6

{3x − 4y = −18

{6x + 2y = −6

{1½x - 2y = −9

___________

\displaystyle \frac{7\frac{1}{2}x}{7\frac{1}{2} = -\frac{15}{7\frac{1}{2}} \\ \\ x = -2[Plug this back into both equations above to get the y-coordinate of 3]; \displaystyle 3 = y

Alternatively, you plug the solution of \displaystyle [-2, 3] into the top answer choice to get this:

{−16 + 12 = −4 ☑

{−34 + 6 = −28 ☑

These are genuine statements, therefore this system of equations is the system we are looking for.

I am joyous to assist you anytime.

A 2000 kilogram sports car accelerates at a ratr of 30 meters per second squared. The velocity of the car is v=at where a is acc
solniwko [45]

Answer:

KE = 900,000t²

Step-by-step explanation:

The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;

m is the mass of the sport car = 2000kg

v is the velocity of the car

Since v = at

v = 30t

Substituting the given values into the KE formula;

KE  1/2 * 2000 * (30t)²

KE = 1000*900t²

KE = 900,000t² Joules where t is the time measured in seconds
