Answer:

C.18(38) +2.5s >/= 750

Step-by-step explanation:

If Patty earns $18 an hour, plus an additional $2.50 each time one of her customers completes survey and Patty plans to work 38 Hours then the inequality which shows the earning of atleast $750 is 18(38)+2.5s>=750 which is option C.

Inequality is like an equation which shows the relationship between two or more variables but it is expressed in greater than, less than, greater than or equal to, less than or equal to signs.

We have been given that the number of surveys is s.

Earning on the basis of hours=18*38

Earning from customer's survey=s*2.50

Earning required by Patty=$750

Inequality which shows atleast $750 earning of Patty is :

18*38+2.50s>=750

we have to use greater than sign because the earning that Patty wants to earn is atleast 750 so it can be equal to or more than 750 dollars.

Hence the inequality will be 18(38)+2.5s<=750.

Answer:

3 feet

Step-by-step explanation:

The diagram showing the pool and the walkway has been attached to this response.

The area of the pool = 15feet x 17 feet = 255 square feet

The total area of the pool and the walkway = 483 square feet

The area of the walkway is the difference between the total area and the area of the pool. i.e

Area of walkway = total area - area of pool

Area of walkway = 483 - 255 = 228 square feet

Now, from the diagram, the walkway can be seen as four rectangles - A, B, C and D - all with a width of x.

Area of rectangle A = (17 + 2x) * x = 17x + 2x²

Area of rectangle B = (17 + 2x) * x = 17x + 2x²

Area of rectangle C = 15 * x = 15x

Area of rectangle D = 15 * x = 15x

Area of walkway = Area of rectangle A + Area of rectangle B + Area of rectangle C + Area of rectangle D

228 = [17x + 2x²] + [17x + 2x²] + [15x] + [15x]

228 = 64x + 4x²

4x² + 64x - 228 = 0

Divide through by 4

x² + 16x - 57 = 0

Now let's solve the quadratic equation:

x² - 3x + 19x - 57 = 0

x(x - 3) + 19(x - 3) = 0

x - 3 = 0     or     x + 19 = 0

x = 3          or      x = -19

Since width cannot be negative, the correct solution is x = 3

Therefore, the width of the walkway is 3 feet

Step-by-step explanation:

Divide 55 by 3 to get the amount he makes each day (18.333333, which rounds to 18.33)

Divide the amount he wants to earn by the amount he earns each day (12.00218221, which rounds to 12)

Answer:

12 days

Step-by-step explanation:

First we need to find how much he makes in 1 day:

if $55 in 3 days that means 55/3=$18.33 a day

now 220/18.33≈12 days

Mr. Sanford’s fortune was $240,000

Answer:  The answers are in the steps.

Step-by-step explanation:

A standard form equation says that Ax + By=C

SO we have to set all the equations to be like that.

43.  y = 12x     Subtract 12x from both sides.

    -12x + 1y = 0      In this case -12  is A, 1 is B , and 0 is C.

44 .  -4y =3x -24      subtract 3x from both sides

     -3x - 4y = -24     A is -3 , B is -4, and  C is -24  

45. 4x = 8y - 12         Subtract 8y from both sides.  

   -8y     -8y

  4x - 8y = -12         A is 4, B is -8 and C  is -12  

46. If we are given the equation y=65x and x represent the number of hours spent driving. And it says that how far do you travel in 8 hours then plot 8 into the equation for x and solve for y.

y = 65(8)

y= 520  

They traveled 520 miles in 8 hours .

Answer:

Step-by-step explanation:

Peter can use the 10% of 80 to find 40% by multiplying the 8.7 by 4 because if 10% =8.7  then multiply 8.7 by 4 which is = 34.8  now subtract this from the total, 87-34.8= 52.2 so 40% of 87 is 52.2.

To find out b we need to find out 10% of 64, so we move the decimal which is 6.4, then multiply 6.4 by 4 which is 25.6. then subtract this from the total, 64-25.6= 38.4

Answer:

1=145°

2=35°

3=145°

Step-by-step explanation:

A straight line always measures 180°

35°+a=180°

a=180°-35°

a=145°

Therefore <1=145°

a=<1=145°

b=<2

a+b=180°

145°+b=180°

b=180°-145°

b=35°

b=<2

c=<3

b+c=180°

35°+c=180°

c=180°-35°

c=145°

Step-by-step explanation:

Answer:

1) Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos, 2) Se siembra siete doceavas partes del terreno con claveles blancos.

Step-by-step explanation:

El enunciado se encuentra incompleto. La pregunta faltante es:

2 ¿Qué parte del terreno corresponde a los claveles blancos?

1) Sea [tex]A[/tex] el área total sembrada con los tres tipos de claveles. Entonces, las áreas sembradas con claveles rojos y claveles amarillos son [tex]\frac{1}{6}\cdot A[/tex] y [tex]\frac{1}{4} \cdot A[/tex], respectivamente.

El área sembrada con claveles rojos y amarillos se obtiene al sumar las áreas correspondientes, es decir:

[tex]x = \frac{1}{6}\cdot A + \frac{1}{4}\cdot A[/tex]

[tex]x = \left(\frac{1}{6}+\frac{1}{4}\right)\cdot A[/tex]

[tex]x = \left(\frac{4+6}{24} \right)\cdot A[/tex]

[tex]x = \frac{10}{24}\cdot A[/tex]

[tex]x = \frac{5}{12}\cdot A[/tex]

Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos.

2) El área sembrada con claveles blancos se obtiene al sustraer el área obtenida en el punto anterior del área total. Esto es:

[tex]x = A - \frac{5}{12}\cdot A[/tex]

[tex]x = \left(1-\frac{5}{12} \right)\cdot A[/tex]

[tex]x = \left(\frac{12}{12}-\frac{5}{12} \right)\cdot A[/tex]

[tex]x = \left(\frac{12-5}{12} \right)\cdot A[/tex]

[tex]x = \frac{7}{12}\cdot A[/tex]

Se siembra siete doceavas partes del terreno con claveles blancos.

Answer:

The answer is 11/16=0.6875.

Answer:

The equation is;

f(x) = -2·x² + 5·x - 1

Step-by-step explanation:

The general form of a quadratic equation  or function f(x) is, f(x) = y = a·x² + b·x + c

Given that the points representing the quadratic function are;

(-1, -8), (0, -1), (1, 2) which  are of the form (x, y)

When x = -1, f(x) = y = -8

Plugging in the above values into the general form of a quadratic function, we have;

-8 = a·(-1)² + b·(-1) + c = a - b + c

-8  = a - b + c.........................(1)

When x = 0, y = -1, we have;

-1 = a·(0)² + b·(0) + c = c

c = -1.......................................(2)

When x = 1, y = 2, which gives;

2 = a·(1)² + b·(1) + c = a + b + c

2 = a + b + c........................(3)

Adding equation (1) to equation (3), we have;

-8 + 2 = a - b + c + a + b + c

-8 + 2 = 2·a + 2·c

From equation (2) c = -1, we get;

-8 + 2 = -6 = 2·a + 2·c = 2·a + 2 × (-1)

-6 = 2·a - 2

-4 = 2·a

a = -2

From equation (3), we have

2 = a + b + c

Substituting the values of a, and c gives;

2 = -2 + b - 1

b = 2 + 2 + 1 = 5

b = 5

The equation is therefore;

f(x) = -2·x² + 5·x - 1.

Answer:

b

Answer:

Option (3)

Step-by-step explanation:

If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.

(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)

                              = -2x³ + x² + 9x + 12x² - 6x - 54

                              = -2x³ + 13x² + 3x - 54

Therefore, Option (3) will be the correct option.

Answer:

(-3, -5)

Step-by-step explanation:

By using the distance formula, we see that the length of RT is [tex]\sqrt{(6+9)^2+(-2+7)^2}[/tex] which equals [tex]5\sqrt{10}[/tex].

The ratio of RS to ST is 3:2, so we can write the distance of RS as [tex](5\sqrt{10} / 5) * 3[/tex] which equals [tex]3\sqrt{10}[/tex]. The distance of ST is then [tex]2\sqrt{10}[/tex].

Since we know the distance of RS and ST, we can find the coordinates of point S by using the distance formula again:

[tex]\sqrt{(6-x)^2+(-2-y)^2} = 3\sqrt{10}[/tex] and [tex]\sqrt{(-9-x)^2+(-7-y)^2} = 2\sqrt{10}[/tex]

We solve for x and y, getting (-3, -5).

The required coordinate point s is (-3, -5).

Given that,
The points R (6,-2) and T (-9,- 7).
To find the coordinates of point S on line RT such that the ratio of RS to ST is 3: 2​

Coordinate, is represented as the values on the x-axis and y-axis of the graph

Here,
Let the coordinates of s be (x, y)
Applying the section formula,
x = [mx₂ + nx₁]/ m+n   ; y = [my₂ + ny₁]/ m+n
Since, m = 3 n = 2,
x = [3*-9 + 6*2] / 3 + 2 ; y = [-7*3 + -2*2] / 3 + 2
x = [-27 + 12] / 5          ; y =  [-21 - 4]/ 5
x = [-15] / 5                  ; y = -25 / 5
x = -3                          ; y = -5

Thus, the required coordinate point s is (-3, -5)
