What is a proportion

Answers

Answer:

a part, share, or number considered in comparative relation to a whole.

Example:A rope's length and weight are in proportion. When 20m of rope weighs 1kg, then: 40m of that rope weighs 2kg. 200m of that rope weighs 10kg.

DescriptionIn mathematics, two varying quantities are said to be in a relation of proportionality, if they are multiplicatively connected to a constant; that is, when either their ratio or their product yields a constant. The value of this constant is called the coefficient of proportionality or proportionality constant.

A complex number z_1z 1 z, start subscript, 1, end subscript has a magnitude |z_1|=7∣z 1 ∣=7vertical bar, z, start subscript, 1, end subscript, vertical bar, equals, 7 and an angle \theta_1=270^{\circ}θ 1 =270 theta, start subscript, 1, en subscript, equals, 270, degrees. Express z_1z 1 z, start subscript, 1, end subscript in rectangular form, as z_1=a+biz 1​ =a+biz, start subscript, 1, end subscript, equals, a, plus, b, i.

Answers

Answer:

z1 = 0+7i.

Step-by-step explanation:

Given the complex number

|z1| = 7 and θ1 = 270°

We are to express z1 in rectangular form as;

z1 = a + bi

|z1| = √a²+b² = 7

a²+b² = 7²

a²+b² = 49

.also argument θ1 = tan^-1(b/a) = 270°

Apply tan to both sides

tan(tan^-1(b/a)) = tan270°

b/a = tan270°

b/a = ∞

Since b/a doesn't exist, this means that the denominator is zero i.e a = 0

Substitute a = 0 into a²+b² = 49 to get b as shown;

0²+b² = 49

b² = 49

b = ±√49

b = ±7

Substitute a= 0 and b = ±7 into the rectangular form of the complex number.

z1 = a+bi

z1 = 0+7i

Hence the value of z1 in its rectangular form is z1 = 0+7i.

Answer:

z = 5.785 + 6.894i

7) -129 = 7(-7 - 4v) + 8v​

Answers

Answer:

v = 4

Step-by-step explanation:

-129 = 7(-7 -4v) + 8v

-129 = -49 - 28v + 8v

-129+49=-20v

-20v = -80

20v = 80

v = 4

Answer:

v=4

Step-by-step explanation:

1) distribute

-129= -49 - 28v + 8v

2) Add like terms

-129= -49 - 20v

3)Isolate

-80= -20v

4)Divide

You are offered two different sales jobs. The first company offers a straight commission of 7% of the sales. The second company offers a salary of $ 330 per week plus 3% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good?

Answers

Answer:

you must make 8250 sale in a week

Step-by-step explanation:

let the number of sale be x

let the total amount earned be y

The first job

7% of x= 0.07x

y=0.07x----------------1

The second job

$330

3% of x= 0.03x

y=330+0.03x-------------2

equating 1 and 2 we have

0.07x=330+0.03x

solving for x we have

330=0.07x-0.03x

330=0.04x

divide both sides by 0.04 we have

330/0.04=x

x=8250

you must make 8250 sale in a week

Pita has 12 coins in her bag.There are 3 1 pound coins and 9 50p coins she takes 3 coins at random.Work out the probability that she takes exactly 2.50

Answers

Answer:

27/220

Step-by-step explanation:

With regards to the above, Pita would have to pick 2 pound coins and 1 50p coin to get £2.50

Then, the probability of picking 1 pound then 1 pound, then 50 Pound

= 3/12 × 2/11 × 9/10

= 9/220

It therefore means that the number of arrangement possible of 2 pounds and 1 50 pounds

= £ - £ - 50 , £ - 50 - £ and 50 - £ -£

= 3

Hence, the required probability

= 3 × 9/220

= 27/220

Tavon has a gift card for $95 that loses $2 for each​ 30-day period it is not used. He has another gift card for $75 that loses $1.50 for each​ 30-day period it is not used. Write and solve an equation for the number of​ 30-day periods until the value of the gift cards will be equal.

Answers

Answer:

the number of​ 30-day periods until the value of the gift cards will be equal is 40

Step-by-step explanation:

Let

x = each 30-day period

Tavon has a gift card for $95 that loses $2 for each​ 30-day period it is not used.

95 - 2x

He has another gift card for $75 that loses $1.50 for each​ 30-day period it is not used

75 - 1.50x

Equate both expression for the number of​ 30-day periods until the value of the gift cards will be equal.

95 - 2x = 75 - 1.50x

95 - 75 = -1.50x + 2x

20 = 0.50x

x = 20/0.50

= 40

x = 40

En un elevador de estación de servicio en el embola grande mide 30cm de diámetro y el pequeño 2 cm de diámetro ¿ que fuerza se necesitará ejercer en el embola pequeño para levantar un automóvil que justo con el embola grande y las vigas de soporte pesa 35,000N?

Answers

Answer:

Necesitamos una fuerza de 155.556 newtons para el émbolo pequeño.

Step-by-step explanation:

Podemos resolver este problema a través del Principio de Pascal, el cual establece que la presión se transmite por igual a través de un sistema cerrado, el cual está representado por el fluido hidráulico del elevador. Asimismo, quiere decir que la presión hidrostática sobre el émbolo pequeño y la presión sobre el émbolo grande son iguales. Entonces:

[tex]p_{1} = p_{2}[/tex] (Eq. 1)

Donde:

[tex]p_{1}[/tex] - Presión sobre el émbolo grande, medido en pascales.

[tex]p_{2}[/tex] - Presión sobre el émbolo pequeño, medido en pascales.

Por la definición de presión tenemos que la fuerza aplicada sobre el émbolo pequeño ([tex]F_{2}[/tex]), medida en newtons:

[tex]\frac{F_{1}}{\frac{\pi}{4}\cdot D_{1}^{2}} = \frac{F_{2}}{\frac{\pi}{4}\cdot D_{2}^{2}}[/tex]

[tex]F_{2} = \left(\frac{D_{2}}{D_{1}} \right)^{2}\cdot F_{1}[/tex] (Eq. 2)

Donde:

[tex]F_{1}[/tex] - Fuerza aplicada sobre el émbolo grande, medida en newtons.

[tex]D_{1}[/tex], [tex]D_{2}[/tex] - Diámetros de los émbolos grande y pequeño, medidos en metros.

Si sabemos que [tex]F_{1} = 35000\,N[/tex], [tex]D_{1} = 0.30\,m[/tex] y [tex]D_{2} = 0.02\,m[/tex], entonces la fuerza necesaria para el émbolo pequeño es:

[tex]F_{2} =\left(\frac{0.02\,m}{0.30\,m} \right)^{2}\cdot (35000\,N)[/tex]

[tex]F_{2} = 155.556\,N[/tex]

Necesitamos una fuerza de 155.556 newtons para el émbolo pequeño.

Marsha buys x pens at $0.70 per pen and one pencil for $0.10. Which function gives the total amount Marsha spends? A C(x) = (0.70+ 0.10)x B C(x) = 0.70x + 0.10 C(x) = 0.70x + 10 C(x) = 0.70x + 0.10x​

Answers

Answer:

B C(x) = 0.70x + 0.10

Step-by-step explanation:

Number of pens = x

Cost of pens = $0.70

Number of pencil = 1

Cost of pencil = $0.10

Total cost, C(x) = (Number of pens * Cost of pens) + (Number of pencil * Cost of pencil)

= (x *0.70) + (1 * 0.10)

= 0.70x + 0.10

C(x) = 0.70x + 0.10

The answer is

B C(x) = 0.70x + 0.10

Joshua buys p pounds of bananas for 40 cents per pound. He pays the clerk with a fifty-dollar bill. The clerk subtracts the total cost of the bananas from the fifty-dollar bill to determine the amount of change to give Joshua. Write an expression to represent this scenario. Then, determine how much change Joshua will receive if he buys three pounds of banana

Answers

Answer: Change he would get = 50-  40p

Joshua will receive $48.8 if he buys three pounds of banana.

Step-by-step explanation:

Given: Cost per pound of banana = 40 cents= 0.40 dollars  [1 cent = 0.01 dollar ]

Number of pounds bought = p

Now, total price need to pay = (Cost per pound of banana) x (Number of pounds bought ) = 0.40p

Now, He pays the clerk with a fifty-dollar bill.

So, the change he would get = 50-  0.40p  , which is the required expression.

When p= 3

then, change he would get = 50-0.4(3)=50-1.2 = $48.8

Joshua will receive $48.8 if he buys three pounds of banana.

Find the slope and y-intercept of y=1/5x+4 o

Answers

Answer:

The Y-intercept of y=1/5x+4 would be y=4. And the X-intercept would be x=-20

Step-by-step explanation:

the slope (m) of the line y = (1/5)x + 4 is 1/5, indicating an upward slope, and the y-intercept (b) is 4,

In the equation y = (1/5)x + 4, the coefficient of x, 1/5, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is 1/5, which means that for every unit increase in x, the y-value increases by 1/5.

The constant term, 4, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is 4, which means that the line crosses the y-axis at the point (0, 4).

To summarize, the slope (m) of the line y = (1/5)x + 4 is 1/5, indicating an upward slope, and the y-intercept (b) is 4, representing the point where the line crosses the y-axis.
