buying x prints is given by the following.
B=45.00 -0.05x
What is the remaining balance on the card if Melissa bought 30 prints?

Answer:

50% of the time for one because one dime has a 50% chance of landing on head or tails so the ratio of this problem would be 120:60 the 60 represents the amount of time it landed on tails or head either one u can choose because it would be the same for both either way so 1/2 of the times you flip a coin of any type the expected times it will land on tails or head 50% of the time

Answer:

x=5

Step-by-step explanation:

Step 1: Flip the equation.

−2x−9=−19

Step 2: Add 9 to both sides.

−2x−9+9=−19+9

−2x=−10

Step 3: Divide both sides by -2.

Exact Form:

x = 9/17

Decimal Form:

x = 0.52941176…

Edit: "but what are the steps to get 9/17"

1. Move all terms containing x to the left side of the equation.

2. Divide each term by −17 and simplify.

\(\text {Hello! Let's Solve this Problem!}\)

\(\text {\underline {The First Step is to Add 4}}\)

\(\text {3x-4+4=14+4}\)

\(\text {3x=18}\)

\(\text {\underline {The Final Step is to Divide 3}}\)

\(\text {3x/3=18/3}\)

\(\text {Your Answer Would Be:}\)

\(\Huge\boxed {x=6}\)

\(\text {Best of Luck!}\)

\(\huge\text{$x=\boxed{6}$}\)

We can solve for the variable \(x\) by isolating it on one side of the equals sign.

Start by adding \(4\) to both sides to cancel out the \(-4\) on the left side of the equation.

\(\begin{aligned}3x-4+4&=14+4\\3x&=18\end{aligned}\)

Now divide both sides of the equation by \(3\) since \(3x\) is the same as \(3*x\) and we want to isolate \(x\), keeping in mind that anything multiplied by \(1\) is itself.

\(\begin{aligned}3x&=18\\3*x&=18\\3*x\div3&=18\div3\\x*3\div3&=18\div3\\x*1&=6\\x&=\boxed{6}\end{aligned}\)

If there is a jar of 100 ml water and if we put a cricket ball inside the jar the water level will rise upto 250 ml. So, the volume of the ball is 150ml.

Given that there is a jar of 100 ml water and if we put a cricket ball inside the jar, the water level will rise up to 250 ml. To find the volume of the ball, we can use the following formula:

Volume of ball = Final volume - Initial volume

Volume of ball = 250 ml - 100 ml

Volume of ball = 150 ml

Therefore, the volume of the cricket ball is 150 ml.

If a bank account of 45000 loses 3.5% of its value each month, based on the exponential function, its value after 1 year is $29,345.40.

An exponential function is described as a mathematical function in the form of f(x) = aˣ.

In this function, x is a variable and a is a constant called the base.

Exponential functions may represent exponential growth or exponential decay.

In this situation, we have an exponential decay function as follows:

Initial value of the bank account = $45,000

Decay rate per month = 3.5%

Number of periods = 12

Decayed value after 1 year = Initial value x (1 - 0.035)^12

= $45,000 x 0.965^12

= $45,000 x 0.65212

= $29,345.40

Thus, the bank account will be valued at $29,345.40 after 1 year.

The standard from of a parabola can be used to obtain the y-intercept

The Factored form can be used to obtain the roots, also known as the x-intercepts.

The Vertex form can be used to obtain the vertex.

The center of the circle is at (1/2, 1/2).

To find the equation of the circle passing through the points (1, 0), (0, 1), and (1, 0), we can use the fact that the center of the circle lies at the intersection of the perpendicular bisectors of any two chords.

Let's denote the center of the circle as (h, k), where h represents the x-coordinate and k represents the y-coordinate. We can calculate the equations of the perpendicular bisectors of the chords formed by the given points and find their intersection to obtain the center of the circle.

The midpoint formula gives us the coordinates of the midpoints of the chords:

Midpoint of (1, 0) and (0, 1):

x₁ = (1 + 0)/2 = 1/2

y₁ = (0 + 1)/2 = 1/2

Midpoint of (0, 1) and (1, 0):

x₂ = (0 + 1)/2 = 1/2

y₂ = (1 + 0)/2 = 1/2

Now, let's calculate the slopes of the chords:

Slope of (1, 0) and (0, 1):

m₁ = (1 - 0)/(0 - 1) = -1

Slope of (0, 1) and (1, 0):

m₂ = (1 - 0)/(1 - 0) = 1

The negative reciprocal of a line's slope gives us the slope of its perpendicular bisector. So, the slopes of the perpendicular bisectors will be:

Slope of the perpendicular bisector of (1, 0) and (0, 1):

m₁' = -1/(-1) = 1

Slope of the perpendicular bisector of (0, 1) and (1, 0):

m₂' = -1/1 = -1

Now, we can find the equations of the perpendicular bisectors using the point-slope form:

Equation of the perpendicular bisector of (1, 0) and (0, 1):

(y - y₁) = m₁'(x - x₁)

(y - 1/2) = 1(x - 1/2)

y - 1/2 = x - 1/2

y = x

Equation of the perpendicular bisector of (0, 1) and (1, 0):

(y - y₂) = m₂'(x - x₂)

(y - 1/2) = -1(x - 1/2)

y - 1/2 = -x + 1/2

y = -x + 1

To find the center of the circle, we need to solve the system of equations formed by the two perpendicular bisectors:

y = x (Equation 1)

y = -x + 1 (Equation 2)

Substituting Equation 1 into Equation 2:

x = -x + 1

Simplifying:

2x = 1

x = 1/2

Substituting the value of x into Equation 1:

y = 1/2

Therefore, the center of the circle is at (1/2, 1/2).

Answer:

Step-by-step explanation:

The transformation represented by g(x) = 2(x-3)^2+4 is a parabolic stretch of the function f(x) = x^2.

The function f(x) = x^2 is a parabola with vertex at (0, 0). The transformation represented by g(x) = 2(x-3)^2+4 stretches this parabola horizontally by a factor of 2, shifting it 3 units to the right and 4 units up.

The resulting function g(x) = 2(x-3)^2+4 is a parabola with vertex at (3, 4). It is the graph of f(x) = x^2 that has been stretched horizontally by a factor of 2, shifted 3 units to the right, and 4 units up.

If there are 22 juniors and 18 seniors, of the juniors, 12 are females, of the seniors, 11 are males, then the probability that a randomly selected student from the class is a male or a junior is 0.611 or 61.1%.

To find the probability that a randomly selected student from the class is a male or a junior, we need to add the probability of selecting a male student from the seniors and the probability of selecting a junior student, regardless of gender.

The probability of selecting a male student from the seniors is 11/18, as given in the problem.

The probability of selecting a junior student, regardless of gender, is (22/40) or (11/20), as there are 22 juniors out of a total of 40 students in the class.

To find the probability of selecting either a male student from the seniors or a junior student, we add these two probabilities:

11/18 + 11/20 = 0.611 or 61.1%

Therefore, the probability that a randomly selected student from the class is a male or a junior is 0.611 or 61.1%.

Answer:

y+2=1/2(x+3)

Why?

Point slope form is written as (y-y1) = m(x-x1) with y1 being the value of y at a certain point, x1 being the value of x at a certain point, and m being slope. y1 and x1 are given to us by the point (-3, -2) letting us know that y1=-2 and x1=-3. The only thing left to find is slope. Parallel lines have the same slope. If the line we are trying to find is parallel to the one given in the question, we just need to find the slope of the equation given. That equation is given in slope-intercept form which is y = mx + b. m is still slope so we can see that the slope is 1/2. Now we can plug m, x1 and y1 into the point slope form equation to get y + 2 = 1/2(x + 3)

Answer:

\(y=\frac{-2}{3} x-15\)

Step-by-step explanation:

First draw a line. I will put it in an attachment so you can see the line.

Now choose to points on the line to use the slope formula.

(0,15) and (3,13).

Slope formula: \(\frac{y2-y1}{x2-x1}\)

Plug in the information needed using the two points chosen.

\(\frac{13-15}{3-0}=\frac{-2}{3}\)

The slope is \(\frac{-2}{3}\).

Now use point-slope formula.

Point-slope formula: y-y1=m(x-x1)

y-15=\(\frac{-2}{3}\)(x-0)

y-15=\(\frac{-2}{3}\)x-0

Subtract 15 from both sides.

y=\(\frac{-2}{3}\)x-15

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.
