Answers

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Represent the terms with a variable

Let x be the amount she earns per hour as a cashier

Let y be the amount she earns per hour as a cook

STEP 2: Interpret the statements in the question as seen below:

[tex]\begin{gathered} 12x+10y=306 \\ 14x+22y=512 \end{gathered}[/tex]

STEP 3: Solve the simultaneous equation using elimination to get x and y

[tex]\begin{gathered} 12x+10y=306---(1) \\ 14x+22y=512----(2) \\ \\ \text{ Multiply equation 1 by 14 and equation 2 by 12} \\ 14\lbrack12x+10y=306\rbrack\Rightarrow168x+140y=4284----(3) \\ 12\lbrack14x+22y=512\Rightarrow168x+264y=6144----(4) \\ \\ \text{Subtract equation 4 from equation 3} \\ 168x\text{ cancels 168x, we have;} \\ 140y-264y=4284-6144 \\ -124y=-1860 \\ \text{Divide both sides by -124} \\ \frac{-124y}{-124}=\frac{-18600}{-124} \\ y=15 \end{gathered}[/tex]

STEP 4: Solve any of equation to get the value of x

[tex]\begin{gathered} \text{From equation 1} \\ 12x+10y=306 \\ y=15\text{, By substitution;} \\ 12x+10(15)=306 \\ 12x+150=306 \\ \text{Subtract 150 from both sides} \\ 12x+150-150=306-150 \\ 12x=156 \\ \text{Divide both sides by 12} \\ \frac{12x}{12}=\frac{156}{12} \\ x=13 \end{gathered}[/tex]

Since x represents the amount she earns as a cashier, hence She earns $13 per hour as a cashier

find the difference between the mode and median of the distribution of data

Answers

Step 1: Rewrite the dot plot in tabular form

Step : Compute the mode

From the table, we can see that the numer appears most ( that is the number with the highest frequence, f) is 4.

Therefore,

mode = 4

Step 3: Find the median

First arrange the data in ascending order. In this case, the data is already in ascending order.

If ∑f is odd, the median is the middle value which is at position

[tex]\frac{\sum f+1}{2}[/tex]

If ∑f is even, the median is the average of the two values at positions

[tex]\frac{\sum f}{2}\text{ and }\frac{\sum f}{2}+1[/tex]

In this case, ∑f = 12 is even.

Therefore, the median is the average of the numbers at position 6 and 7

number at position 6 is 3

number at position 7 is 4

Hence, the median is given by

[tex]\frac{3+4}{2}=\frac{7}{2}=3.5[/tex]

median = 3.5

Step 4: Find the difference between the median and mode

The difference is given by

[tex]4-3.5=0.5[/tex]

Hence the difference is 0.5

In a bake sale, you recorded the number of muffins sold and the amount of sales in a table as shown. a. What is a function that relates the sales and the number of muffins?b. How many muffins would you have to sell to make at least $175.000 in sales?a. Write the function.s= ______. (Type and expression using m as the variable.)

Answers

The function is S = N*1.75. The number of muffins that must be sold to earn $175 is 100.

The number of muffins sold and the amount of sales in a bake sale are shown in the given table. The number of muffins sold is 12, 14, 17, and 18. The amount of the sale is $21, $24.5, $29.75, and $31.5. We can write these in the form of coordinates as (12, 21), (14, 24.5), (17, 29.75), and (18, 31.5).

We should first determine if the ratio is constant. The ratio is the division of the sales amount by the respective number of muffins sold. We find that the ratio of all the pairs is the same and is equal to 1.75. We can form an equation as given below :

S = N*1.75

The variables "S" and "N" represent the sales amount and the number of muffins, respectively. We need to find the number of muffins that need to be sold to earn $175.

S = N*1.75

175 = N*1.75

N = 100

Answers

Los polinomios se clasifican según el número de términos que lo componen.

Los términos de una expresión están separados entre sí por los signos "+" y "-"

Se conoce como "monomio" a un polinomio con un solo término.

Son ejemplos de monomios:

6x²

2x

z

Un "binomio" es un polinomio de dos terminos.

Por ejemplo:

2x-3y

4x²+1

5y⁴z-2x²

Un "trinomio" es un polinomio con tres términos.

Por ejemplo:

2x+3y+z

y²-z+7

Un "cuadrimonio" es un polinomio de cuatro términos

Por ejemplo

xy+5y-9z+4

Los polinomios también pueden clasificarse según su grado. El grado del polinomio está dado por el valor del mayor exponente.

Un polinomio de grado cero es aquel que tiene coefficientes igual a cero.

Por ejemplo

0x²+0x

Un polinomio de primmer grado es aquel en el que la variable está elevada a la uno. En general este exponente no se escribe por lo que en un polinomio grado uno las variables no van a tener exponente.

Por ejemplo

x+2

x+y+4

Un polinomio de segundo grado es aquel cuyo mayor exponente es dos, es decir, tiene un termino elevado al cuadrado.

Por ejemplo:

x+y²+3

x-9y+5z²-7

Un polinomio de tercer grado es aquel cuyo mayor exponente es tres, es decir, al menos una variable está elevada al cubo.

Por ejemplo:

x

x³+y²

2x-y³+25

Teniendo estas definiciones en cuenta, puedes clasificar el polinomio:

[tex]2xy+9b-4x+9[/tex]

Este polinomio tiene 4 términos, "2xy", "9b", "4x" y "9" por lo que se lo puede clasificar como un cuadrimonio.

Como puedes ver, ninguna de las variables tiene exponente, es decir que, el exponente de mayor valor es 1, por lo que se puede clasificar como un polinomio de primer grado.

Entonces esta expresión es un cuadrimonio de primer grado

Your company fireworks show is getting bigger, The boss has requested that the viewing area (which is 4 ft x 6 ft) be doubled; the parking area (which is 540 ft x 75 ft) be doubled; and the city ordinance requires the fireworks to be in the air less than 4 seconds and not go any higher than 600 feet.

Answer the following questions:

1. Determine the dimensions of the new viewing area. The existing area is 6 ft long by 4 ft wide.

2. Determine the dimensions of the new parking area. The existing area is 540 ft long by 75 feet wide.

3. Determine the height of the fireworks and how long they are in the air using the following equation:

ℎ= −500/9 t^2 + 1000/3 t + 10

Answers

The solution to the questions are

New viewing area dimension: 8 ft by 12 ftNew parking area dimension: 1080 ft by 150 ftHeight of fireworks: 510 units

The dimension of the new viewing area

From the question, we have the following parameters:

Initial dimension of the viewing area:

4 ft by 6 ft

The scale of dilation is given as

Scale = 2 (i.e. doubled)

Using the above as a guide, the new dimensions are calculated using

New = Old * Scale

So, we have

New = (4 ft by 6 ft) x 2

Evaluate

New = 8 ft by 12 ft

The dimension of the new parking area

The given parameters are

Initial dimension of the parking area:

540 ft by 75 ft

We use the same scale factor as (a) i.e.

Scale = 2 (i.e. doubled)

Using the above as a guide, the new dimensions are calculated using

New = Old * Scale

So, we have

New = (540 ft by 75 ft) x 2

Evaluate

New = 1080 ft by 150 ft

The height of fireworks

The function is given as

ℎ= −500/9 t^2 + 1000/3 t + 10

Differentiate the function

So, we have

ℎ'= −1000/9 t + 1000/3

Set the differentiated function to 0

So, we have

−1000/9 t + 1000/3 = 0

This gives

1000/9 t = 1000/3

Multiply  both sides by 9/1000

t = 3

Substitute 3 for t in ℎ= −500/9 t^2 + 1000/3 t + 10

ℎ = −500/9 x 3^2 + 1000/3 x 3 + 10

Evaluate

ℎ = 510

Hence, the height is 510 units

In how many seconds the second bird catches the crab?

The equation that describes the height of the crab is:

d = -t^2 + 10

The equation that represents the path of the second bird is:

d' = 5t + 5

The bird will be able to catch the crab when both are at the same height, this happens when:

-t^2 + 10 = 5t + 5

We need to solve this for t.

-t^2 + 10 - 5t - 5 = 0

-t^2 - 5t + 5 = 0

Using the quadratic formula we will get:

t = (5 ± √( (-5)^2 - 4*(-1)*5))/(2*-1)

t =  (5 ± 6.7)/(-2)

We only care for the positive solution, which is:

t = (5 - 6.7)/(-2)  = 0.85

So the bird catches the crab after 0.85 seconds.

The polynomial 9x-7=-7

Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. We are able to perform mathematical operations on polynomial expressions such addition, subtraction, multiplication, and positive integer exponents but not division by variables.

The terms Poly (meaning "many") and Nominal (meaning "terms") make form the word polynomial.

The highest exponent of a monomial contained within a polynomial is referred to as the polynomial's degree. So-called polynomial degrees are polynomial equations with one variable having the largest exponent.
