The probability that it is going to rain tomorrow is 1/7. What are the odds in favor of it raining tomorrow

Answer: 41 degrees

Step-by-step explanation: To determine the angle at which the pizza was cut, we need to use the formula for the area of a sector of a circle:

A = (θ/360)πr²

where A is the area of the sector, θ is the central angle of the sector (in degrees), π is a constant (approximately equal to 3.14), and r is the radius of the circle.

In this case, we know that the area of the sector that corresponds to the slice of pizza that was eaten is 17 square inches. We also know that the pizza has a diameter of 14 inches, which means that the radius is 7 inches.

Substituting these values into the formula, we get:

17 = (θ/360)π(7²)

17 = (θ/360)49π

θ/360 = 17/(49π)

θ = (17/49π) * 360

θ ≈ 41 degrees (rounded to the nearest whole number)

Therefore, the pizza was cut at an angle of approximately 41 degrees.

Side A and Side B are both equal to 32/3, which is 10 2/3 centimeters and the total number of hours the girls spent cleaning is 15 hours.

The perimeter of a shape can be found by adding up the lengths of all its sides.

The perimeter of a triangle is the sum of the lengths of its three sides, so in this case the equation to solve for the length of each of the two sides is:

Perimeter = 2 x Side A + Side B

32 = 2x + x

3x = 32

x = 32/3

Therefore, Side A and Side B are both equal to 32/3, which is 10 2/3 centimeters.

Answer: Since the parabola opens down and has a focus at (0, -12), its directrix is a horizontal line located 12 units above the vertex. Let the vertex of the parabola be (h, k).

Since the focal diameter is 20, the distance between the focus and the directrix is also 20. Therefore, the directrix is the horizontal line y = k + 12, and the distance from the vertex to the focus is equal to the distance from the vertex to the directrix, which is 10.

Using the definition of a parabola, we can write:

sqrt((x - h)^2 + (y - k)^2) = 10 + (y - k - 12)

Squaring both sides, we get:

(x - h)^2 + (y - k)^2 = (10 + y - k - 12)^2

Expanding the right-hand side and simplifying, we get:

(x - h)^2 + (y - k)^2 = (y - 2)^2

Simplifying further, we get:

x^2 - 2hx + h^2 + y^2 - 2ky + k^2 = y^2 - 4y + 4

Rearranging the terms, we get:

x^2 - 2hx + h^2 + 2ky - 4y + k^2 - 4 = 0

Since the parabola opens down, the coefficient of x^2 must be negative. Therefore, we can write:

-(x^2 - 2hx + h^2 + 2ky - 4y + k^2 - 4) = 0

Multiplying out the negative sign, we get:

-h^2 + 2hx - 2ky + 4y - k^2 + 4 = 0

Therefore, the equation of the parabola that opens down, has focus (0, -12), and a focal diameter of 20 is:

-h^2 + 2hx - 2ky + 4y - k^2 + 4 = 0

Step-by-step explanation:

To find the annual interest rate, we can use the formula:

simple interest = (principal x rate x time) / 100

where principal is the initial amount, rate is the annual interest rate, and time is the time period in years.

We know that the principal is $100, the simple interest is $3, and the time period is 6 months, which is half a year.

So, we can plug in these values and solve for the annual interest rate:

$3 = ($100 x rate x 0.5) / 100

$3 = $0.5 x rate

rate = $3 / $0.5

rate = 6

Therefore, the annual interest rate is 6%.

Answer:

To calculate the annual interest rate, we can use the simple interest formula:

I = P * r * t

Where:

- I is the interest earned

- P is the principal amount

- r is the annual interest rate

- t is the time period in years

In this case, we know that the principal amount is $100, the interest earned is $3, and the time period is 6 months, or 0.5 years. We can plug these values into the formula and solve for r:

3 = 100 * r * 0.5

r = 3 / (100 * 0.5)

r = 0.06, or 6%

Therefore, the annual interest rate is 6%.

Joseph must invest approximately $110840.16 today to reach his retirement goal of $2 million, assuming a consistent rate of inflation of 7.5%.

To calculate the amount Joseph needs to invest today to reach his retirement goal of $2 million, we can use the future value formula for a lump sum investment:

[tex]$FV = PV x (1 + r)^n[/tex]

where FV is the future value, PV is the present value, r is the rate of return (in this case, the inflation rate of 7.5%), and n is the number of years.

In this case, we want to solve for PV, which represents the amount Joseph needs to invest today. We know that:

Joseph has 40 years until he retires (65 - 25 = 40)

His retirement goal is $2 million

The inflation rate is 7.5%

Plugging these values into the formula, we get:

[tex]$2,000,000 = PV \times (1 + 0.075)^{40}[/tex]

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

The slope of the line is 7/5 its y-intercept is (0,5) and x-intercept is (-25/7,0) when the equation of the line is 7x‐5y=‐25.

To write the equation of the line 7x-5y=-25 in slope-intercept form, we need to solve for y:

7x - 5y = -25

-5y = -7x - 25

y = (7/5)x + 5

Therefore, the equation of the line in slope-intercept form is y = (7/5)x + 5.

To find the slope, we can see that the coefficient of x is 7/5, so the slope is 7/5.

To find the y-intercept, we can see that the y-intercept is the value of y when x = 0. Plugging in x=0 into the equation, we get:

y = (7/5)(0) + 5 = 5

Therefore, the y-intercept is (0,5).

To find the x-intercept, we can set y=0 and solve for x:

0 = (7/5)x + 5

-5 = (7/5)x

x = -25/7

Therefore, the x-intercept is (-25/7,0).

To draw an accurate graph, we can plot the x- and y-intercepts and then use the slope to draw the line through those points. The slope of 7/5 means that for every 5 units to the right, the line goes up 7 units. We can use this to plot additional points and draw the line. The line should pass through the points (-25/7,0) and (0,5), and continue in both directions.

As the height of the rider increases by 1 inch, the bike frame increases by 0.29 inches

Step-by-step explanation:

Lets label what we know here:

b = size of the bike frame in inches

h = height of the rider in inches

We are also given the equation [tex]b=0.29h+1.35[/tex], which is in slope intercept form. This means that the y intercept is 1.35 and the slope is 0.29.

This means that, as the height of the rider increases by 1 inch, the bike frame will also increase. Lets put this to the test:

[tex]b=0.29(1) + 1.35[/tex]

[tex]b=1.64[/tex]

Answer:

The answer is: m = B(3x + 1) degrees.

Step-by-step explanation:

In the given equation m/B= (3x + 1)°, we need to find the measure of m.

To find m, we need to isolate it on one side of the equation.

We can do this by multiplying both sides of the equation by B, which gives us m = B(3x + 1)°.

This means that m is equal to the product of B and (3x + 1)°.

We can simplify further by multiplying 3x + 1 by the degree symbol, which gives us m = B(3x + 1) degrees.

The formula used in this problem is m/B = angle measure, where m is the unknown side, B is the length of the known side, and the angle measure is given in degrees.

When solving problems like this, it is important to watch for units and make sure they are consistent throughout the equation.

For example, if B is measured in meters, then the units of m should also be in meters.

A real-world example of using this formula could be calculating the height of a building based on the length of its shadow and the angle of the sun's rays.

Answer: m = B(3x + 1) degrees.
