Without putting the first card back, you pick a second card at random. 4, 5, 6, 7 What is the probability of picking an odd number and then picking an even number? Write your answer as a fraction or whole number

Answer/Explanation:

The answer is B!

A mixed number from an improper fraction is when you take that improper fraction and fix it into whole numbers. It's kind of like a decimal but with fractions.

Examples:

6/4 = 1 and 2/4 or 1 and 1/2

9/2= 4 and 1/2

17/6= 2 and 5/6

Make sense?

improper fraction into a mixed number
1. divide the numerator by the denominator

2. the quotient becomes the whole number

3. the remainder becomes the numerator

4. the denominator remains the same.

12 : 5 = 2 remainder 2

Answer:

x(x−4)

Step-by-step explanation:

Answer:

x (x-4)

Step-by-step explanation:

Utilizando los dos puntos dados, veremos que la relacion lineal es:

Una ecuación lineal se escribe como:

y = a*x + b

donde a es la pendiente y b es la ordenada al origen.

Sí sabemos que una linea pasa por los puntos (x₁, y₁) y (x₂, y₂), entonces la pendiente va a ser:

a = (y₂ - y₁)/(x₂ - x₁).

Aca tenemos los dos puntos:

(20km, $190)

(25 km, $242)

Entonces la pendiente será:

a = ($242 - $190)/(25km - 20km) = $10.4 /km

y = ($10.4 /km)*x + b

Para obtener el valor de b, usamos uno de los puntos. Evaluando en x = 20km deberiamos obtener y = $190, entonces:

$190  =  ($10.4 /km)*20km + b

$190 = $208 + b

$190 - $208 = b = -$18

Entonces la ecuación es:

y = ($10.4 /km)*x -$18

B) La tarifa minima es lo que obtenemos con x = 1 km, entonces es:

y =  ($10.4 /km)*1 km - $18 = -$7.6

Notar que da un valor negativo, lo que indica que la relación quizas no es lineal.

C) La cuota por kilometro es la pendiente de la relación lineal, en este caso será: $10.4 /km.

Answer: A

Step-by-step explanation:

Answer:

y = 37

Step-by-step explanation:

the 3 angles lie on a straight line and sum to 180°

sum the 3 angles and equate to 180

y + 29 + 40 + 2y = 180 , that is

3y + 69 = 180 ( subtract 69 from both sides )

3y = 111 ( divide both sides by 3 )

y = 37

Answer:

2.5

Step-by-step explanation:

Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5

1: 5 x 5 = 25

2: 5 x 2 = 10

3: 25 - 10 = 15

4: 15/6 = 2.5

The weight of each triangle is 2.5

Have an amazing day!

PLEASE RATE!!

Answer: 2.5

Step-by-step explanation:

What we know:

Both sides need to be equal, and one side already has a constant defined value.

That value is 25 (units)

How to solve:

By using a simple algebraic equation, we can find the value of a triangle's weight. X will represent a square's weight, and y will represent a triangle's weight.

Process:

Set up equation                                                 5x = 2x + 6y

Substitute                                                           5(5) = 2(5) + 6y

Simplify                                                               25 = 10 + 6y

Cancel out                                                         -10    -10

                                                                           15 = 6y

Separate variable                                              /6    /6

Solve                                                                   2.5 = y

Solution: y (triangle weight) = 2.5

You can check this by adding 2.5 6 times (15) to 5 2 times (10). This will equal 25, which would balance out the other side

Answer: julie spent 4 more dollars than mindy

Step-by-step explanation: julie spent 36 dollars in the dress while mindy spent 32 dollars

Julie spend  [tex]\$4[/tex]  more money than Mindy on the dress.

Off/Discount is an amount that is subtracted from the regular price of an item.

The original price of dress [tex]= \$39.99[/tex]

Julie buys the dress for [tex]10\%[/tex] off at its original price.

So,

Julie buys the dress for  [tex]= 39.99-(39.99*\frac{10}{100} )[/tex]

                                         [tex]= \$35.991[/tex]

Mindy buys the same dress for [tex]20\%[/tex] off at its original price.

Mindy buys the same dress for [tex]= 39.99-(39.99*\frac{20}{100} )[/tex]

                                                    [tex]=\$31.992[/tex]

So,

Julie spend more money than Mindy on the dress [tex]=35.991-31.992[/tex]

                                                                                    [tex]=\$3.999[/tex]

                                                                                    [tex]=\$4[/tex]

Hence, we can say that Julie spend  [tex]\$4[/tex]  more money than Mindy on the dress.

Answer:

x=5

Step-by-step explanation:

An isosceles trapezoid has two pairs of congruent base angles. This means angle F has to equal angle E. So we have 2x^2+21=3x^2-4. Move the variables to one side and we get 25=x^2. Square root both sides and we get two values x=5 and x=-5. Since angles cannot necessarily be negative, we only want the positive value. In this case x=5.
