Which linear inequality represents the graph below?
A. 12-x+1
B. y> -*x+1
C. y24x+1
D.y> 5x+

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

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

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

no you do not get the same answer

This is the order in which you should approach problems, doing otherwise may lead to a wrong answer

P - parenthesis -- meaning solve whatever is the the parenthesis

E - exponents -- an example of an exponent is [tex]2^{3}[/tex] which equals 8

MD - multiplication/division

AS - addition / subtraction

for our particular problem, we have

9 + 2(3)

multiplication trumps addition thus we perform multiplication first

9 + 6 = 15 ---CORRECT

if we were to addition first we would get

9 + 2(3) = 11(3) = 33 This would be WRONG

note: multiplication and division are on the same level

         subtraction and addition are on the same level

if you encounter a problem like 4 ÷ 2 * 3. perform the calculation from left to right thus we would have 4 ÷ 2 = 2 and then 2 * 3 = 6

same applies for addition subtraction

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

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.

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

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.

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.

Answer:

Amount left = $5.5

Step-by-step explanation:

Given:

Total amount = $20

Spend for admission = $5.50

Spend for rent = $3.75

Spend for 2 bottle = $1.25 each

Spend for snack = $2.75

Find:

Amount left

Computation:

Amount left = Total amount - Spend for admission - Spend for rent - Spend for 2 bottle - Spend for snack

Amount left = $20 - $5.5 - $3.75 - 2($1.25) - 2.75

Amount left = $5.5

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

From the equation y = 6x -2, we can get (by plugging in x = 0 and y = 0) 2 points:

y = 6(0) - 2 --> y = -2 --> (0, -2)

0 = 6x - 2 --> 2 = 6x --> 1/3 = x --> (1/3, 0)

We can plot those 2 points to get the graph shown.

The graph will show a line that starts from the point (0, -2) and increases as we move to the right

To graph the line with the equation y = 6x - 2, we can plot a few points and connect them to form a line. Here are a few points that satisfy the equation:

When x = 0, y = 6(0) - 2 = -2. So, we have the point (0, -2).

When x = 1, y = 6(1) - 2 = 4. So, we have the point (1, 4).

When x = -1, y = 6(-1) - 2 = -8. So, we have the point (-1, -8).

We can plot these points on a coordinate plane and draw a line passing through them.

The graph will show a line that starts from the point (0, -2) and increases as we move to the right. The slope of 6 indicates that for every increase of 1 in the x-coordinate, the y-coordinate increases by 6. The line has a positive slope, moving upward from left to right.
