What are the slopes of lines parallel and perpendicular to the line 3x+y=9
(Select one answer per blank).

Answer: Michael's paycheque = $ 1704

Donald's paycheque =  $ 568

Jacob's paycheque = $ 648

Step-by-step explanation:

Let x = Michael's paycheque

Donald's paycheque = [tex]\dfrac13x[/tex]

Jacob's paycheque = [tex]\dfrac 13 x+80[/tex]

Together, the three friends earned $2920 in one week.

[tex]\Rightarrow\ x+\dfrac13x+\dfrac13 x+80=2920\Rightarrow\ (\dfrac{3+1+1}{3})x=2920-80\\\\\Rightarrow\ \dfrac{5}{3}x=2840\\\\\Rightarrow\ x=2840\times\dfrac{3}{5}\\\\\Rightarrow\ x=1704[/tex]

Michael's paycheque = $ 1704

Donald's paycheque = [tex]\dfrac{1704}{3}=\$ 568[/tex]

Jacob's paycheque = $ 568+80 = $ 648

Answer:

An exact number is one that has no uncertainty. An example is the number of tires on a car (exactly 4) or the number of days in a week (exactly 7). An approximate number is one that does have uncertainty. ... The number can be the result of a measurement.

Answer:

y = 1.25x + 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

( -4 , -3 ) ( 8 , 12 )

12 + 3   15 = 5

8 + 4    12 = 4

↑ slope = 5/4

↓ point slope form: y - y₁ = m ( x - x₁ )

y + 3 = 5/4 ( x + 4 )

y + 3 = 5/4x + 5

-3

y = 5/4x + 2

Answer:

38 in^2 and 26 in^2

Step-by-step explanation:

1. The formula of the area of a trapezoid is [tex]A = \frac{1}{2} (b_{1} + b_{2})h[/tex] where b = base and h = height.

So, [tex]A = \frac{1}{2} (7+12)(4)[/tex] = 38 [tex]in^{2}[/tex]

2. [tex]A = \frac{1}{2}(5+8)(4)[/tex] = 26 [tex]in^{2}[/tex]

No, Betsy is not correct. She likely forgot to multiply by 1/2 when calculating the area. The correct answer is 26 inches squared.

Answer:

an=a1+(n-1)*-6

Step-by-step explanation:

a1= 3

the recursive formula is an= a1+ (n-1)d

d= how you get from one to the other

to get from 3 to -18 you could either subtract 21 or multiply it by -6

to find which one you have to look at the next number which is 108

to get from -18 to 108 you would either add 126 or multiply it by -6

since multiplying by -6 is in both that is the answer

d= -6

an=a1+(n-1)*-6

We can split the m-8 into 2 terms m and -8 each multiplying the next ( ) like this...

m(m+5)-8(m+5)

Now we expand

m^2+5m-8m-40

then simplify!

m^2-3m-40

Done!

Step-by-step explanation:

For the real estate agent: To find percent of a number, you can just divide by 100 and times it by the percent number, in this case it is 3.

$575,000 / 100 = $5,750

$5750 * 3 = $17,250

The agent earns $17,250.

For the computer store: Use the percentage and multiply it by 0.45, or whatever the percentage is.

150 * 0.45 = 67.5. This is the markup.

Now add the original value back to the markup.

150 + 67.5 = 217.5. This is the selling price of the computer.

For the video game: Use the percentage and multiply it by 0.25, or whatever the percentage is.

$55 * 0.25 = $13.75. This is the discount.

Now subtract the discount from the first value.

$55 - $13.75 = $41.25. This is the sale price.

Answer:

Sanjay age=16 years; Dhruv age = 40 Years

Step-by-step explanation:

Let Sanjay’s present age be ‘x’, then Dhruv age is x+24

10 years back, Sanjay’s age was (x-10) years and Dhruv’s age

was (x+14)

Given: x+14 =5(x-10)

X=16 years

Sanjay age=16 years; Dhruv age = 40 Years

Answer:

x = 3 x = -4

x = 1 x = 8

Step-by-step explanation:

x² + x - 12

(x + 4) (x - 3)

x + 4 = 0

x = - 4

-----------

x - 3 = 0

x = 3

x² - 9x + 8

(x - 8) (x - 1)

x - 8 = 0

x = 8

-----------

x - 1 = 0

x = 1

Answer:

El camino diagonal debe medir 100 metros de largo.

Step-by-step explanation:

Podemos encontrar el camino usando Pitágoras:

[tex] D^{2} = L^{2} + A^{2} [/tex]

En donde:        

D: es el camino diagonal = hipotenusa

L: es el largo = 80 m = cateto

A: es el ancho = 60 m = cateto

Entonces, el camino diagonal es:

[tex] D = \sqrt{L^{2} + A^{2}} = \sqrt{(80 m)^{2} + (60 m)^{2}} = 100 m [/tex]

Por lo tanto, el camino diagonal debe medir 100 metros de largo.

Answer:

1) El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Step-by-step explanation:

El perímetro es una medida de la distancia alrededor de una figura y el área da una idea de qué tanta superficie cubre dicha figura.

Entonces, el perímetro es la medida obtenida como resultado de la suma de los lados de una figura geométrica plana. Es decir, el perímetro es lo que mide el contorno de la figura.

El área de un triángulo es igual a base por altura dividido por 2.

Siendo r el radio de la circunferencia, el perímetro será calculado como:

P=2*π*r

y el área será:

A=π*r²

1) En este caso, el perímetro es calculado como:

P= 6 cm + 8 cm + 5 cm= 19 cm

Y el área del triángulo es calculada como:

[tex]A=\frac{base*altura}{2} =\frac{8 cm*3.73 cm}{2}[/tex]

A= 14,92 cm²

El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) Siendo el diámetro un segmento de recta que va desde un punto de la circunferencia a otro y pasa por el centro del círculo y l radio la distancia desde el centro del círculo hasta un punto de la circunferencia, entonces, el radio es la mitad del diámetro.

Siendo el diámetro de la circunferencia 4,5 cm, entonces el radio r tiene un valor de 2,25 cm.

Entonces el perímetro será calculado como:

P=2*π*2,25 cm

P= 14,14 cm

y el área será:

A=π*(2,25 cm)²

A= 15,90 cm²

La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Answer:

The answer should be $3.125 or $3.13 rounded.

Step-by-step explanation:

First I divided 1.25 by 100 because 1 meter equals 100 centimeters.

1.25 ÷ 100 = 0.0125

Now that we know that it costs 0.0125 for 1 centimeter we multiply it by 250.

0.0125 * 250 = 3.125

Since it says to round to the nearest cent, the answer should be 3.13

Hope this helps! :)
