Last week Bill earned $210 for a 30-hour
week. What was his pay rate? What would
he have earned for a 40-hour week?

Answer:

minus 5 by 7

Step-by-step explanation:

5 - 7 = -2

2 - 3 = -1

The smaller the negative integer, the bigger the number.

Let the number be x.

13 + 5x < 30

5x < 30 - 13

5x < 17

x < 17/5

Step-by-step explanation:

let number be x

equation= 13 + 5x =or<30

if 13+5x=30

5x=17

x=3.4

Answer:

x = -1

y = -5

Step-by-step explanation:

y = x - 4                                     y = x - 4

2x + 3y = -17                             y = (-1) - 4

2x + 3(x - 4) = -17                      y = -1 - 4

2x + 3x - 12 = -17                       y = -5

5x - 12 = -17

5x - 12 + 12 = -17 + 12                 Check

5x = -5                                    2x + 3y = -17

5x/5 = -5/5                           2(-1) + 3(-5) = -17

x = -1                                        -2 + -15 = -17

                                                   -17 = -17

Answer:

Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.

Step-by-step explanation:

Los Cuantiles (cuartiles, deciles, percentiles) son medidas de localización cuya  función es informar del valor de la variable que ocupará la posición (en tanto por  cien) que interese respecto de todo el conjunto de variables.

Los cuartiles son medidas estadísticas de posición que tienen la  propiedad de dividir la serie estadística en cuatro grupos de números iguales de  términos.

El primer cuartil o cuartil inferior es aquel valor de la variable tal que la cuarta parte (25%) de las observaciones son inferiores o iguales a él, y el resto (75%) es superior o igual. El segundo cuartil es la mediana, ya que se trata del valor localizado en la mitad de la distribución. Finalmente, el tercer cuartil o cuartil superior es un valor tal que las tres cuartas partes de las observaciones son inferiores o iguales a él.

En otras palabras, el primer cuartil Q1, es el valor en el cual o por debajo del cual queda aproximadamente un cuarto (25%) de todos los valores de la sucesión (ordenada); El segundo cuartil Q2 es el valor por debajo del cual queda el 50% de los datos (Mediana), el tercer cuartil Q3 es el valor por debajo del cual quedan las tres cuartas partes (75%) de los datos. Es decir, Q1, Q2 y Q3 determinan los valores correspondientes al 25%, al 50% y al 75% de los datos respectivamente. Q2 coincide con la mediana.

Para saber el puntaje máximo que obtuvo el 75% de los alumnos se debe calcular el tercer cuartil.

Answer:

  No

Step-by-step explanation:

The initial balance at the beginning of the year is not zero, so the balance is not proportional to the time since the beginning of the year.

__

A proportional relationship always starts at zero when the independent variable is zero.

Answer:

24

Step-by-step explanation:

The computation of the number of vertices does one of the base of regular prism is shown below:

V + F = E + 2

V + 14 = 36 + 2

V + 14 = 38

V  = 38 - 14

= 24

Answer:

Step-by-step explanation:

y = 1/8 x

Answer: 9

Step-by-step explanation:

12 + 8 + 7 + 12 + 6 = 45

There are 5 numbers

45 / 5 = 9

Answer:

mean = 9

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] , then

mean = [tex]\frac{12+8+7+12+6}{5}[/tex] = [tex]\frac{45}{5}[/tex] = 9

Answer:

She can get 10 pounds of steak and 10 pounds of chicken.

Step-by-step explanation:

As Jacie wants to have at least 20 pounds of meat, you can write the following  equation:

x+y=20, where

x refers to the pounds of steak

y refers to the pounds of chicken

Also, since the statement indicate that the steak is $8 per pound and chicken is $4 per pound and Jacie wants to spend at most 120 dollars on meat, you can write the following equation:

8x+4y=120

So, you have the following equations:

x+y=20 (1)

8x+4y=120 (2)

Now, you can solve for x in (1):

x=20-y (3)

Then, you can replace (3) in (2) and solve for y:

8(20-y)+4y=120

160-8y+4y=120

160-120=8y-4y

40=4y

y=40/4

y=10

Finally, you can relace the value of y in (3) to find x:

x=20-y

x=20-10

x=10

According to this, the answer is that she can get 10 pounds of steak and 10 pounds of chicken.

Answer:

the answer is y=30x

Step-by-step explanation:

however many inches times 30 is the consistent answer to the equation    

Answer:

y=30x

Step-by-step explanation:

We can start out by writing our slope-intercept form equation: y=mx+b. In this case, our y-intercept is 0, so we can write y=mx.

Let's find the slope. We can take the points (1,30) and (2,60). We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find our slope. Plug these values in, and we get [tex]\frac{60-30}{2-1}[/tex]. Evaluate this, and our slope is 30. So, our equation is y=30x.

Hope this helped!

Answer:

Step-by-step explanation:

Circumference

Circumference of a circle is calculated by the formula:

= π * diameter

= 3.14 * 52

= 163.28 units

Area

Area of a circle is calculated by the formula:

= π * radius²

Radius = DIameter / 2

= 52 / 2

= 26 units

Area = 3.14 * 26 * 26

= 2,122.64‬ units²

Answer:

the answer is 3.26and3.51

Step-by-step explanation:

the difference between them is 0.25 so by adding 3.01+0.25=3.26

3.26+0.25=3.51

3.51+0.25=3.76

3.76+0.25=4.01
