Pamela bought 9 pounds of birdseed. What is the weight in ounces?

Answer:

A. The expression of "40 times the sum of 24 and 36" would be 40 x (24+36), and the value would be 2400.

B. for the words portion it would be "20 times the sum of 650 and 350", and the value of that expression is 20,000.

C. The expression of "divide the difference between 1,600 and 400 by 4" should be 1200 / 4, and if that is the correct way to format the expression then the value would be 300.

D. for the words portion it would be "100 times the sum of 78 and 12", and the value of that expression is 10,000.

Step-by-step explanation:

Answer:

40 times the sum of 24 and 36

40 × (24 + 36)

2400

20 times the sum of 650 and 350

20000

divide the difference between 1600 and 400 by 4

(1600 - 400) ÷ 4

300

100 times the sum of 78 and 12

9000

Answer:

Dos terceras partes de un número: [tex]\frac{2}{3}*x[/tex]

Un número menos su doble: x - 2*x

La suma de los cuadrados de tres números: x² + y² + z²

El producto de dos números divididos por un tercer número: [tex]\frac{x*y}{z}[/tex]

La suma de tres números consecutivos: x+(x+1)+(x+2)

Step-by-step explanation:

Una expresión algebraica es un conjunto de números y letras que se combinan con los signos de las operaciones aritméticas. En otras palabras, el lenguaje algebraico es el que utiliza letras, símbolos y números para expresar en forma breve y concisa enunciados en los que se pide realizar operaciones matemáticas.

Entonces, siendo x, y, z números al cual desear aplicar una operación aritmética, y teniendo en cuenta que:

las siguientes expresiones escritas en lenguaje algebraica serán:

Dos terceras partes de un número: [tex]\frac{2}{3}*x[/tex]

Un número menos su doble: x - 2*x

La suma de los cuadrados de tres números: x² + y² + z²

El producto de dos números divididos por un tercer número: [tex]\frac{x*y}{z}[/tex]

La suma de tres números consecutivos: es la suma del primer número, más el segundo que seria el primero más uno, más el tercero que seria el primero más 2. Esto es: x+(x+1)+(x+2)

Answer:

the  25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player

Step-by-step explanation:

The computation of the fabric used on a headband and wristband for each player is as follows:

For headband

= 843.81 inches ÷ (29 players + 4 coaches)

= 843.81 inches ÷ 33

= 25.57 inches

And, for the wristband, it would be

= 279.56 inches ÷ 29 players

= 9.64 inches

Hence, the  25.57 inches and 9.64 inches is the fabric used for headband and wristband for each player

Answer:45°

Step-by-step explanation:

First we need to find x

(5x-5)+(3x+3)+(5x)=180

Simplify

13x-2=180

Add 2 to each side

13x=182

Divide each side by 13

x=14

Now apply our x to angle B

3(14)+3

42+3

45

Angle B=45°

Answer:

Total amount taken in by the depeloper from the sale of apps = sum(5.99 * x * P(x))

= 5.99*0*0.05 + 5.99*20*0.25 + 5.99*40*0.18 + 5.99*60*0.12 + 5.99*80*0.3 + 5.99*100*0.1

= 319.87

Ans: $319.87

Step-by-step explanation:

The expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.

The continuous uniform distribution, sometimes known as the rectangle distribution, is a family of symmetric probability distributions in probability theory and statistics.

We have:

The number of apps a developer sells daily has the probability distribution represented in the table:

Number of Apps, x       0      20    40     60      80    100

P(x)                              0.05  0.25  0.18   0.12     0.3     0.1

Each app sells for $5.99

We can calculate the expected daily total dollar amount taken in by the developer from the sale of apps:

The total amount is taken in by the developer from the sale of apps:

= sum(5.99x[P(x)])

= 5.99×0×0.05 + 5.99×20×0.25 + 5.99×40×0.18 + 5.99×60×0.12 +

   5.99×80×0.3 + 5.99×100×0.1

= 0 + 29.95 + 43.128 + 43.128 + 143.76 + 59.9

= 319.866 ≈ $319.87

Thus, the expected daily total dollar amount taken in by the developer from the sale of apps is $319.87 option (E) is correct.

Answer:

The correct option is;

(-2, 213) and (2, -213)

Step-by-step explanation:

The reflection of a point across the x-axis is given as follows;

The coordinates of the point of the pre-image = (x, y)

The coordinates of the point of the image after reflection = (x, -y)

The reflection of a point across the y-axis is given as follows;

The coordinates of the point of the pre-image = (x, y)

The coordinates of the point of the image after reflection = (-x, y)

Therefore, from the given points, The reflection across the y-axis of the point (-2, 213) is (2, 213) and the reflection across the x-axis of the point (2, 213) is (2, -213)

Answer:

$44.25

Step-by-step explanation:

12.5 + 2.75 + .5 + 20 + 8.5 =44.5

2.75 + .5 = 3.25

20 + 12.5 + 32.5

3.25 + 32.5 + 8.5 = 44.25

Answer:

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Step-by-step explanation:

you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain

Dough = 6 ounces

Suase = 4 ounces

Dough + sauce = 6 + 4 = 10

Let x = total number of guests

Dough ingredients + sauce ingredients = 130

10x = 130

Divide both sides by 10

x = 130/10

= 13

x = 13

Number of guests = 13

Total ounces of dough = 6 ounces × 13 guests

= 78 ounces of dough

Total ounces of sauce = 4 ounces × 13 guests

= 52 ounces of sauce

Therefore,

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

then add the zero

Answer:

Step-by-step explanation:

a triangles angles add up to 180

subtract 102 from 180

180-102

that’s 78

a and b are equal so divide 78 by 2 to get 39

a and b are both 39

Answer:

A= 39 B= 39

Step-by-step explanation:

A triangle = 180 degrees

subract the 102 from 180 to get 78

the tqo angles are equal because of the dashes which means you can divide 78 by 2 to get the answer.

Answer:

a) La pizza tenía 8 porciones.

b) Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones.

f) Véase la imagen adjunta para mayor detalle.

Step-by-step explanation:

Sean [tex]x[/tex], [tex]y[/tex], [tex]z[/tex] las razones de consumo de Julián, Mica y Juan, de acuerdo con una lectura cuidadosa del enunciado tenemos que:

[tex]x+y+z=1[/tex] (1)

(i) Julián comió 2/8 del total:

[tex]x = \frac{2}{8}[/tex] (2)

(ii) Juan comió el doble que Julián:

[tex]z = 2\cdot x[/tex] (3)

(iii) Mica comió la mitad de lo que comió Juan:

[tex]y = \frac{1}{2}\cdot z[/tex] (4)

Al aplicar (2) en (3), tenemos que Juan comió:

[tex]z = \frac{4}{8}[/tex]

Y ahora se aplica el resultado anterior a (4):

[tex]y = \frac{1}{2}\cdot \frac{4}{8}[/tex]

[tex]y = \frac{2}{8}[/tex]

a) El total de porciones queda representado en el denominador de las fracciones calculadas. Por tanto, la pizza tenía 8 porciones.

b) El número de porciones consumido por cada persona está representada por el numerador de las fracciones calculadas. Por tanto, Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones en tanto que la suma de porciones consumidas de las tres personas es igual al valor del denominador.

f) A continuación, anexamos el gráfico correspondiente que sustenta todos los cálculos matemáticos hechos en puntos anteriores.

Answer:

After 100 songs

Step-by-step explanation:

2.50x=1.50x+50

.50x=50

÷.50

X=100

Great Songs will be the better deal after 100 songs.

Mathematical operations can also be defined by using built-in functions to subtract, divide, and multiply. The arithmetic operator is the one who conducts the arithmetic operation.

* Multiplication procedure: Values on both sides of the operator are multiplied.

For instance, 7×2 = 14

/ Division: Divides the left operand by the right operand

For instance, 4/2 = 2

MyTunes imposes a fee of $2.50 per song. Great Songs charges $1.50 for each song and includes a $50 one-time membership fee, as stated in the question.

Let the songs that come after Great Songs would be x, the better the deal.

⇒ 2.50x = 1.50x + 50

⇒ 0.50x = 50

Divided by 0.50 into both sides of the equation,

⇒ x = 100

Therefore, Great Songs will be the better deal after 100 songs.

Answer:

C is not a function but D is

Step-by-step explanation:

For one input, you can only have one output for this to be a function. For table C, the input of 4 has 4 different outputs, so it cannot be a function.

D is a function however, because each input has only one output, even if the output is the same number.
