Answer:

1/4

Step-by-step explanation:

Assuming the number cube is a six-faced die, you have

1 2 3 4 5 6

three odd numbers, and three even numbers. Therefore, the chance of it landing on an odd number or even number is 3/6, which equals 1/2. That means you have a 50% chance to get an odd number, or an even number.

So, you have two die. Both have a 50/50 chance of getting an even or odd number. So what's the chance of one landing on an odd number, and the other landing on an even number?

You would have a 25% chance for an even and then an even number

You would have a 25% chance for an odd and then an odd number

You would have a 25% chance for an even and then an odd number

You would have a 25% chance for an odd and then an even number.

25% as a simplified fraction is 1/4. Therefore, 1/4 is your answer.

A company provided the following data: Selling price per unit: 60 Variable cost per unit 20 Total fixed costs 400,000 HOw many u

EastWind [94]

Answer:

The company needs to sell 9000 units in order to turn a profit of $40,000

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

From the question we can get some important hints before creating our formula. First the Selling Price will be profit so it will be a positive number, but both unit cost and fixed costs are losses so they will be negative values in our formula. Also our formula will depend on the amount sold which we can represent as the variable x. With these hints we can create our formula as the following

$(60x-20x)-400,000 = y$

Where:

x is the amount of units created and sold
y is the total profit after selling x-units

Now that we have our formula the question asks how many units need to be sold in order to earn a profit of $40,000. We can calculate this by replacing the $40,000 with y and solving for x like so,

$(60x-20x)-400,000 = 40,000$ .... add 400,000 on both sides

$40x= 360,000$ ... divide both sides by 40

$x= 9000$

The company needs to sell 9000 units in order to turn a profit of $40,000

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

What values of x and y satisfy the system of equations {10x+3y=−5−5x−4y=10? (0,−53) (25,−3) (−2,0) (12,−103)

Kitty [74]

Answer:

The solution of the equation

( 0.4 ,-3)

Step-by-step explanation:

Explanation:-

Step(i):-

Given system of equations

10 x+3 y = −5 ...(i)

- 5 x - 4 y = 10 ...(ii)

Multiply (i) with '5'

10 × 5 x + 3×5 y = - 25

50 x + 15 y = 25 ...(iii)

Multiply (ii) with '10'

-5 × 10 x - 4×1 0 y = 100

- 50 x - 40 y =100 ...(iv)

Step(ii):-

Solving (iii) and (iv)

50 x + 15 y =- 25

- 50 x - 40 y =100

- 25 y = 75

Dividing ' - 25' on both sides, we get

y = -3

substitute y = -3 in equation (i) , we get

10 x+3 y = −5

10 x - 9 = - 5

10 x = -5 + 9

$x = \frac{4}{10}$

x = 0.4

Final answer:-

The solution of the equation ( 0.4 ,-3)
