Lacey earns 680 each week. She pays $91.80 in federal income tax. The other taxes are $17.00. Her pay after taxes is $547.40 How much does lacey pay in state income tax?

With a principal of $7000 earning a 7% annual interest rate compounded annually over 8 years, the total amount accumulated at the end of the period would be $11,595.76.

To calculate the total amount accumulated, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the principal (P) is $7000, the interest rate (r) is 7%, the interest is compounded annually (n = 1), and the number of years (t) is 8.

Using the formula, we have A = 7000(1 + 0.07/1)^(1*8) = 7000(1.07)^8 ≈ $11,595.76.

Therefore, at the end of 8 years, the total amount accumulated would be approximately $11,595.76.

the value of n remains indeterminate in this case.To find the value of n in the expression (y^20)(y^-5)^2i equivalent to yn, we can simplify the expression first.

Starting with (y^20)(y^-5)^2i, we can simplify the exponent by multiplying the exponents of y:
(y^20)(y^-5)^2i = y^(20 + (-5 * 2))i = y^(20 + (-10))i = y^10i.

Now, we can equate this simplified expression to yn:
y^10i = yn.

To find the value of n, we can compare the exponents:
10i = n.

Since the imaginary unit i represents the square root of -1, and the exponent in this case is not purely real, we cannot find a specific value for n. Therefore, the value of n remains indeterminate in this case.

The formula of height h = (3v) / (π * r^2)To find the height (h) of a cone given the volume (v) and the radius of the base (r), we can rearrange the equation v = (π * r^2 * h) / 3.

By multiplying both sides by 3 and dividing by π * r^2, we isolate the variable h and obtain the formula h = (3v) / (π * r^2). Substituting the appropriate values for volume and radius into this equation allows us to calculate the height of the cone.

To solve for the height (h) in the equation v = (π * r^2 * h) / 3, we first multiply both sides by 3 to eliminate the fraction. This results in the equation 3v = π * r^2 * h. Next, we isolate the variable h by dividing both sides of the equation by π * r^2, giving us the formula h = (3v) / (π * r^2). By substituting the known values for volume (v) and radius (r) into this equation, we can calculate the height (h) of the cone. It is important to ensure that the units for volume and radius are consistent and compatible to obtain the correct result.

Jen's average speed for the entire round trip, including the outbound and return trips, is 30 mph.

To determine Jen's average speed for the entire round trip, we need to calculate the total distance traveled and the total time taken.

Let's assume the distance between Boston and Cape Cod is "d" miles.

For the outbound trip from Boston to Cape Cod, Jen traveled at a speed of 60 mph. The time taken for this leg of the trip is given by:

Time = Distance / Speed

Time = d / 60

For the return trip, it took Jen 3 times longer due to heavy traffic. Therefore, the time taken for the return trip is 3 times the time taken for the outbound trip:

Time for return trip = 3 * (d / 60) = (3d) / 60

The total time for the round trip is the sum of the outbound and return trip times:

Total Time = d / 60 + (3d) / 60 = (d + 3d) / 60 = 4d / 60 = d / 15

The total distance for the round trip is twice the distance from Boston to Cape Cod:

Total Distance = 2d

Now, we can calculate Jen's average speed by dividing the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 2d / (d / 15)

Average Speed = 2 * 15

Average Speed = 30 mph

Therefore, Jen's average speed for the entire round trip, including the outbound and return trips, is 30 mph.

The dimensions of the bedroom in the blueprint are approximately 1/9 ft by 1/12 ft.

To find the dimensions of the bedroom in the blueprint, we can use the given scale of 1/4 in = 3 ft.

First, let's convert the dimensions of the actual bedroom into feet:

Length of the actual bedroom = 16 in * (1 ft / 12 in) = 16/12 ft = 4/3 ft

Width of the actual bedroom = 12 in * (1 ft / 12 in) = 12/12 ft = 1 ft

Now, let's use the scale to find the dimensions of the bedroom in the blueprint:

Length of the bedroom in the blueprint = Length of the actual bedroom * Scale

Length of the bedroom in the blueprint = (4/3 ft) * (1/4 in / 3 ft)

Length of the bedroom in the blueprint = 4/3 * 1/12

Length of the bedroom in the blueprint = 4/36

Length of the bedroom in the blueprint = 1/9 ft

Width of the bedroom in the blueprint = Width of the actual bedroom * Scale

Width of the bedroom in the blueprint = (1 ft) * (1/4 in / 3 ft)

Width of the bedroom in the blueprint = 1 * 1/12

Given a quadrilateral ABCD, with the sides AB and DC parallel and equal in length. Let us denote angle BAD as ∠α and angle ADC as ∠β. Now, we have to find the values of the variables x and y such that ABCD is a parallelogram.

Parallelogram has a pair of parallel sides. So, we have AB ∥ CD. It is given that ∠α = ∠β and AB = CD. So, by angle-angle-side rule, the two triangles ABD and DCA are congruent.

In triangle ABD, we have:∠DAB = 180° - ∠α = 180° - ∠β (as ∠α = ∠β)⇒ ∠DAB + ∠CDA = 180° (linear pair of angles)⇒ ∠CDA = ∠β.In triangle DCA, we have:∠CDA = ∠β (as obtained above)⇒ ∠CAD = ∠α (as ∠α = ∠β)⇒ ∠BDC = 180° - ∠α = 180° - ∠β (linear pair of angles)⇒ ∠BDC = ∠DAB.In quadrilateral ABCD, the adjacent angles are supplementary. So, we have:∠BDC + ∠BCD = 180° (adjacent angles are supplementary)⇒ ∠DAB + ∠BCD = 180° (as ∠BDC = ∠DAB)⇒ ∠BCD = 180° - ∠DAB.In triangle ACD, we have:∠C = ∠C (common)⇒ ∠CAD + ∠BCD = 180° (angles of a triangle add up to 180°)⇒ ∠α + (180° - ∠DAB) = 180°⇒ ∠α + ∠β = 180°.

Now, we can solve for x and y.In triangle ABD, we have:AB = BD⇒ 3x = 21 - x⇒ 4x = 21⇒ x = 21/4.In triangle DCA, we have:CD = DA⇒ 3y = 22 - y⇒ 4y = 22⇒ y = 11/2. Therefore, the value of x is 21/4 and the value of y is 11/2.

The minimum value of the function occurs at the vertex of the parabola, which has x-coordinate equal to -b/2a, where a and b are the coefficients of the quadratic function.

So, we have;

f(x) = 1.2x² - 6.3x + 1.2

Comparing this to the general form of the quadratic function: f(x) = ax² + bx + c, we can see that a = 1.2 and b = -6.3.

To find the x-coordinate of the vertex, we use the formula x = -b/2a:

x = -(-6.3) / 2(1.2)

PS and PC are both equal to 16000 feet when SC is 24000 feet. These lengths are determined based on the relationship between the centroid and the midpoints of the sides in a triangle.

In a triangular park, with point P as the centroid, if SC (one of the sides) is equal to 24000 feet, the lengths of PS and PC can be determined.

To find the lengths of PS and PC, we need to consider the properties of a centroid in a triangle. The centroid divides each median into two segments, with the ratio of 2:1.

In other words, the distance from the centroid to the midpoint of a side is two-thirds of the length of the entire median.

In this case, since SC is equal to 24000 feet, PS and PC can be calculated as follows:

PS = (2/3) * SC = (2/3) * 24000 = 16000 feet.

The dimensions of the rectangle are 16 inches in width and 24 inches in length.

Let's assume the width of the rectangle is x inches. According to the problem, the length is 8 inches greater than the width, so the length can be represented as (x + 8) inches.

The formula for the area of a rectangle is length multiplied by width. In this case, the area is given as 384 square inches. So, we can set up the equation:

Length * Width = Area

(x + 8) * x = 384

Expanding the equation:

x^2 + 8x = 384

Rearranging the equation to solve for x:

x^2 + 8x - 384 = 0

We can solve this quadratic equation by factoring or using the quadratic formula. Factoring it, we find:

(x - 16)(x + 24) = 0

So, x = 16 or x = -24.

Since dimensions cannot be negative, we discard the negative solution. Therefore, the width of the rectangle is 16 inches.

Substituting this value back into the equation for the length:

Length = x + 8 = 16 + 8 = 24 inches

Hence, the dimensions of the rectangle are 16 inches in width and 24 inches in length, which gives an area of 384 square inches.

The expression (5x)² is equal to ___ x², where the twos are cubes.

To simplify the expression (5x)², we need to apply the exponent rules. Since the twos are cubes, we need to cube both the base and the exponent.

(5x)² can be rewritten as (5x)³³. Applying the exponent rule for a power of a product, we raise each factor inside the parentheses to the third power:

(5x)³³ = (5)³(x)³ = 125x³.

Therefore, the expression (5x)² is equal to 125x³, where the twos are cubes.

It would take 15/4 or 3.75 hours to paint one full room.

If it takes 3/2 of an hour to paint 2/5 of a room, we can use proportions to find how long it would take to paint one full room. Let's represent the time it takes to paint one full room as x.

Then we have the following proportion:

2/5 room : 3/2 hour = 1 room : x

To solve for x, we can cross-multiply: (2/5) * x = (3/2) * 1

Simplifying the right side gives:(2/5) * x = 3/2

Multiplying both sides by the reciprocal of 2/5 gives us:x = (3/2) / (2/5)

Multiplying by the reciprocal is the same as dividing, so we have:x = (3/2) * (5/2)

Simplifying gives:x = 15/4

Therefore, it would take 15/4 or 3.75 hours to paint one full room.

3 students have been in a choir but not on a radio show.

In order to determine how many students have been in a choir but not on a radio show, we can use the Principle of Inclusion-Exclusion (PIE) to solve the problem.

The PIE formula is: n(A or B) = n(A) + n(B) - n(A and B)

Here, A represents the set of students who have been on a radio show, B represents the set of students who have been in a choir, and A and B represents the intersection of the two sets.

Using the information provided, we know that:

n(A) = 3 (3 students have been on a radio show)n(B) = 3 (3 students have been in a choir)n(A and B) = 0 (0 students have been both on a radio show and in a choir)

Therefore, using the PIE formula:

n(A or B) = n(A) + n(B) - n(A and B)n(A or B) = 3 + 3 - 0n(A or B) = 6

So, 6 students have either been on a radio show or in a choir. However, we want to find the number of students who have been in a choir but not on a radio show. To do this, we can subtract the number of students who have been in both from the total number of students who have been in a choir:

n(B but not A)

= n(B) - n(A and B)n(B but not A)

= 3 - 0n(B but not A)

= 3

Therefore, 3 students have been in a choir but not on a radio show.
