Answer: You will be charged $ 210 for 10 GB of data.
Step-by-step explanation:
Given : Cost of cell phone plan = $90
Additional charge over 4GB for each GB = $20
If 10 GB data is used , then after 4 GB you need to pay for 6 additional GB (10-4=6)
Total charge = (Cost of cell phone plan)+ (Additional charge) x (Number of gigabytes over 4 GB)
i.e. Total charge = $(90+20(6))
= $ (90+120)
= $ 210
Hence, you will be charged $ 210 for 10 GB of data.
A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?
Answer:
Step-by-step explanation:
The direct variation is defined as
where, k is constant of proportionality.
It is given that a direct variation function contains the points (-8,-6) and (12, 9).
Substitute x=-8 and y=-6 in the above equation.
Divide both sides by -8.
The value of constant of proportionality is . So, the required equation is
At x=12,
It means, the line passing through (12,9). Hence, the equation is correct.
Therefore, the equation of the function is .

Find all the values of k so that the quadratic expression factors into two binomials. Explain the process used to find the values.
Answers:
k = 23k = 10k = 5k = 2k = -2k = -5k = -10k = -23There are eight items in that list above.
===================================
Explanation:
We'll use the AC method of factoring.
The first term has coefficient 3. The last term is -8. Multiply them to get 3*(-8) = -24.
Now let's list all the ways to multiply two integers to get -24
-1*24-2*12-3*8-4*6-6*4-8*3-12*2-24*1For each pair of factors listed, we'll add up those pairs. Each sum we get represents a possible value of k
k = -1+24 = 23k = -2+12 = 10k = -3+8 = 5k = -4+6 = 2k = -6+4 = -2k = -8+3 = -5k = -12+2 = -10k = -24+1 = -23Note the symmetry. For instance we have 10 as one sum and -10 as another sum.
-------------------------------
Let's go over an example. Let's say that k = 10
The expression 3x^2+kx-8 turns into 3x^2+10x-8
From the list above, we see that -2+12 = 10. So the two values -2 and 12 will help us factor.
Break up the 10x into -2x+12x and then factor by grouping like so
3x^2 + 10x - 8
3x^2 - 2x + 12x - 8
(3x^2 - 2x) + (12x - 8)
x(3x-2) + (12x - 8)
x(3x-2) + 4(3x - 2)
(x+4)(3x-2)
Therefore, 3x^2 + 10x - 8 factors into (x+4)(3x-2)
We can use the FOIL rule, distribution, or the box method to confirm this.
I'll let you try out other values of k to see how 3x^2+kx-8 factors.

For the problem 9 + 2(3) do you get the same final answer if you add first as you do if you multiply
first?
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

Ken, a meteorologist, is predicting next year's temperatures in New York City. He predicts that, in August, the average low temperature will be 20°C, and that the temperature will drop by 4°C in September. Ken's predicted temperature for September is how many ºC
Answer:
16 °C
Step-by-step explanation:
We are told that Ken predicts that, in August, the average low temperature will be 20°C, and that the temperature will drop by 4°C in September.
Now, in a standard 12 month calendar, the month of August comes before the month of September.
Thus, in September a drop off by 4°C from 20°C means that the new temperature in September is; 20°C - 4°C = 16 °C

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.
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
graph the line with the equation y=6x-2
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.

Luke borrowed 15000 to pay his college tuition after he graduates he will repay the loan along with simple interest after 2 years luke will owe a total of 17250 what is the simplest interest rate on lukes loan
Answer: 7.5%
Step-by-step explanation:
Given: Principal amount = $15,000
Time =- 2 years
Final Amount (Principal + interest)= $17,250
Interest = Final Amount - Principal amount
= $ ( 17250 - 15000 )
= $ 2250
Formula for interest : principal x rate x time
[tex]2250=15000\times rate \times 2\\\\\Rightarrow\ rate =\dfrac{2250}{15000\times2}\\\\\Rightarrow\ rate =0.075\\\\\Rightarrow\ rate =0.075\times100\%=7.5\%[/tex]
Hence, the simplest interest rate on lukes loan =7.5%

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?
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.

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
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
