Answers

Answer 1

Answer:

A!

Step-by-step explanation:

Edge 2021 :)

Answer 2

The solution to the system of equations  is a=2, b=-2 and c=0

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equations are

2a+b+c=2 ...(1)

-a+b-C=-4 ...(2)

a-2b+2c= 6 ...(3)

Isolate a for 2a+b+c=2

a=2-b-c/2

substitute a in equation 2 and 3

-2+b+c/2 -b-c=-4

2-b-c/2-2b+2c=6

(3b-c-2)/2=-4

5b+3c+2/2=6

Isolate b for (3b-c-2)/2=-4

b=c-6/3

By simplification we get a=2, b=-2 and c=0

Hence, the solution to the system of equations  is a=2, b=-2 and c=0

Answers

D. the probability that a customer buys EITHER a bird or a mouse.

The correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

What is probability?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given that, a pet store sells mice, reptiles, and birds,

Let event A = A customer buys a mouse.

Let event B = A customer buys a bird.

We need to tell that,

What does P(A or B) = 0.25 mean in terms of this problem,

So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,

Hence, the correct answer is:  The probability that a customer buys either a mouse or a bird is 25%.

Una tableta contiene 500 mg de paracetamol, ¿cuántas tabletas se obtendrán con 5kg del mismo medicamento? xfavor ayudenme con explicación y todo lo necesito para el sabado

Answers

Answer:

Se pueden obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad de 5 kg del medicamento

Step-by-step explanation:

La cantidad en masa de paracetamol en una tableta = 500 mg de paracetamol / tableta

El número de comprimidos que contienen 500 mg de paracetamol que se pueden obtener a partir de 5 kg del medicamento (paracetamol) se calcula dividiendo los 5 kg del medicamento por los 500 mg de paracetamol / comprimido de la siguiente manera;

[tex]El \ nmero \ de \ tableta = \dfrac{5 \ kg \ paracetamol}{500 \ mg \ paracetamol/tableta }[/tex]

Observamos que 5 kg = 5,000,000 mg

Por lo tanto;

[tex]El \ numero \ de \ tableta = \dfrac{5,000,000 \ mg \ paracetamol}{500 \ mg \ paracetamol/tableta } = 10,000 \ tabletas[/tex]

Por tanto, podemos obtener 10.000 comprimidos de 500 mg de paracetamol a partir de la cantidad dada de 5 kg del medicamento.

How many trays of each type of cookies should be make to maximize his profit?

Answers

Step-by-step explanation:

this is a linear programming problem.

the objective is to maximize profit

let the chocolate be x

and cookies be y

Maximize

2.5x+2y=P

constraint milk

3x+y=9------------------1

constraint flour

2x+4y=16----------------2

solving 1 and 2

3x+y=9

2x+4y=16

multiply 1 by 2 and 2  3 to eliminate x we have

  6x+2y=18

 6x+12y=48

-0-10x=-30

10y=30

y=30/10

y=3

put y= 3 in eqn 1 we have

3x=9-3

3x=6

x=6/3

Answers

Answer:

Some subjects are more important than others. You have to be working in a field where the concepts you learn in school.

I'd say that everything you learn in middle school and Algebra 1 + 2 , maybe a little of geometry you'll use at some point in your life.

Step-by-step explanation:

Everyone has asked themselves: When will I use math? Well, hundreds of careers use skills learned in high school math on a daily basis. The truth is virtually every career you could choose will build on the basic skills learned in High School Math.

But there are a number of craft and fine arts careers that do not require math skills or involve using them regularly, such as being a painter or sketch artist. Craft and fine artists produce original works that will be displayed or sold, and they may work with a range of materials, such as paint, glass or ink.

To conclude I might say that math is important and everyone should know more than just some basic skills in math.Life is long and sometime harsh for most of us and not always we get in life what we want,probably we will end up doing a job that it was not our dream job.

Or our preferences might change depending on different aspects of life.So knowing a 'little bit' from every subject we do in school is not a bad thing,at the end we know all that greatest things are achived will a hard work!So we should learn as much as we can! Math especially!

And all our hard work will be payed at the end,just remember this!

Which of the following is true about the lines defined by the equations 4x−2y=6 and x+2y=14? .
A.The lines share the same y-intercept.
B.Both lines intersect at point (1,−1).
C.The lines are perpendicular.
D.The lines are parallel.

Answers

Answer:

            Only:  C.  The lines are perpendicular.

Step-by-step explanation:

              4x - 2y = 6                           x + 2y = 14

           - 2y = - 4x + 6                        2y = - x + 14

               y = 2x - 3                             y = - ¹/₂x + 7

A.

y-intecept:  (0, -3)                                 (0, 7)

The lines don't share the same y-intercept

B.

x=1    ⇒   y = 2(1)-3 = -1      and        y = -¹/₂(1) + 7 = 6¹/₂ ≠ -1

the line  x+2y=14 doesn't go through point (1,−1) so the lines couldn't intersect at point (1,−1)

Slope:      m₁ = 2                                    m₂ = -¹/₂

C.

m₁· m₂ = 2·(-¹/₂) = -1

The lines are perpendicular.

D.

m₁  ≠  m₂          The lines are not parallel
