Kaia needs braces, which will cost $2,400. Her insurance deductible is $1500, after which her insurance pays 80% of all costs. How much will Kaia need to pay for her braces?
A.$2,200
B.$1,680
C.$180
D.$480
Kaia will pay a $1,500 deductible and the remaining 20% not covered by insurance after the deductible, totaling to $1,680 for her braces.
To calculate how much Kaia will need to pay for her braces, we need to take into account her insurance deductible and the percentage her insurance will cover after that deductible is paid. Kaia's braces cost $2,400, so let's break it down step-by-step:
Kaia pays her insurance deductible, which is $1,500. So, $2,400 - $1,500 = $900 remains.
Her insurance then covers 80% of the remaining $900. To calculate this, we use 80% of $900: ($900 x 0.80) = $720.
Since the insurance pays $720 of the remaining cost, Kaia is left with 20% of $900 to pay out of her pocket. To calculate this, we take 20% of $900: ($900 x 0.20) = $180.
Therefore, Kaia will need to pay $1,500 (deductible) plus $180, for a total of $1,680.
a metalworker has a metal alloy that is 15% copper and another alloy that is 55% copper. how many kilograms of each alloy should the metalworker combine to create 90kg of a 47% copper alloy
x = amount at 15%
90-x = amount of 55%
0.15x + 0.55(90-x) = 0.47(90)
0.15x +49.5 - 0.55x = 42.3
49.5 - 0.40x = 42.3
-0.40x = -7.2
x = -7.2 / -0.4 = 18 kg of 15% copper
90-18 = 72 kg of 55% copper
Gavin goes to the market and buys one rectangle shaped board. The length of the board is 16 cm and width is 10 cm. if he wants to add a 2 cm wooden border around the board, what will be the area of the rectangle board?
The area of the rectangle board, including the wooden border, is 280 cm².
The student's question pertains to finding the new area of the rectangle board after adding a 2 cm wooden border around it. Initially, the board has dimensions of 16 cm in length and 10 cm in width. To account for the new wooden border, we add 2 cm to each side of the board. This means that the new length will be 16 cm + 4 cm (2 cm for each side of the length) and the new width will be 10 cm + 4 cm (2 cm for each side of the width).
The calculation will be as follows:
New Length = 16 cm + 4 cm = 20 cm
New Width = 10 cm + 4 cm = 14 cm
Area = New Length * New Width
Area = 20 cm * 14 cm
Area = 280 cm²
Therefore, the area of the rectangle board with a 2 cm border added around it will be 280 cm².

The calculated coordinates of the point P is P (-3/2, -3/2)
How to determine the coordinates of the point PFrom the question, we have the following parameters that can be used in our computation:
A = (1, 6)
Also, we have
B = (-2, -3)
And we have the partition to be
m : n = 5 : 1
The coordinate of the partition is calculated as
P = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)
Substitute the known values in the above equation, so, we have the following representation
P = 1/(5 + 1) * (5 * -2 + 1 * 1, 5 * -3 + 1 * 6)
This gives
P = 1/6 * (-9, -9)
So, we have
P = (-3/2, -3/2)
Hence, the coordinate is P = (-3/2, -3/2)

To find the coordinates of point P along the directed line segment AB, we can use the concept of section formula and plug in the given values to find the coordinates (-3/2, -3/2).
Explanation:To find the coordinates of point P along the directed line segment AB, we can use the concept of section formula. The section formula states that if a point P divides a line segment AB in the ratio m:n, then the coordinates of P can be found using the formula:
P(x,y) = [(mx2 + nx1)/(m+n), (my2 + ny1)/(m+n)]
Using this formula, we can plug in the values: m=5, n=1, x1=1, y1=6, x2=-2, y2=-3 to find the coordinates of point P.
P(x,y) = [(5*(-2) + 1*1)/(5+1), (5*(-3) + 1*6)/(5+1)] = [(-10+1)/6, (-15+6)/6] = [-9/6, -9/6] = (-3/2, -3/2)

What construction does the image below demonstrate?
Answer:
The construction depicts the inscribing of a hexagon in a circle.
Step-by-step explanation:
These are the following steps to inscribe a hexagon in a circle.
1. We mark a point anywhere on the circle. This mark is the first vertex of the hexagon.
2. Now we will set the compass on this vertex and set the width to the center of the circle. This is the radius of the circle.
3. Now we will make an arc across the circle which is the next vertex of the hexagon.
4. Now moving the compass on to the next vertex and drawing another arc, which becomes the third vertex of the hexagon.
5. Repeat step 4 until all vertices are marked.
6. Lastly, we will draw a line between each successive pairs of vertices, for a total of six lines.
Now we can see a hexagon inscribed in a circle.

The Statue of Liberty and its pedestal are 92.99 meters tall. The pedestal is 0.89 meters taller than the Statue of Liberty. How tall is the Statue of Liberty? Equation and answer.
Final answer:
To find the height of the Statue of Liberty, we set up an equation considering the total height of the pedestal and the height difference between the statue and the pedestal. Solving the system of linear equations, we determine that the height of the Statue of Liberty itself is 46.05 meters.
Explanation:
To find how tall the Statue of Liberty is, excluding its pedestal, we can set up an equation based on the information given. Let's denote the height of the Statue of Liberty as S, and the height of the pedestal as P.
We know that the total height of the Statue of Liberty and its pedestal is 92.99 meters, and we can express that as:
S + P = 92.99
Additionally, it is given that the pedestal is 0.89 meters taller than the Statue of Liberty, so we have:
P = S + 0.89
Using substitution, we can replace P in the first equation with S + 0.89:
S + (S + 0.89) = 92.99
This simplifies to:
2S + 0.89 = 92.99
To find the height of the Statue of Liberty (S), we subtract 0.89 from both sides of the equation:
2S = 92.99 - 0.89
2S = 92.10
And then we divide both sides by 2 to solve for S:
S = 92.10 / 2
S = 46.05
So, the height of the Statue of Liberty itself is 46.05 meters.

Fo two disk i problem 3 what is the ratio of linear accerlation of a point on the rim of disk a
The ratio of the linear acceleration of a point on the rim of disk A to the linear acceleration of a point on the rim of disk B is [tex]\( \frac{r_A}{r_B} \), where \( r_A \) and \( r_B \)[/tex] are the radii of disks A and B, respectively.
Linear acceleration ( a ) of a point on the rim of a rotating disk is given by [tex]\( a = r \alpha \)[/tex], where ( r ) is the radius of the disk and [tex]\( \alpha \)[/tex] is the angular acceleration.
Since both disks are rotating with constant angular acceleration, the linear acceleration of a point on the rim of each disk is directly proportional to the radius of the disk.
Therefore, to find the ratio of the linear accelerations, we only need to compare the radii of the two disks.
Let [tex]\( r_A \) and \( r_B \)[/tex] be the radii of disks A and B, respectively.
The ratio of linear accelerations is given by [tex]\( \frac{a_A}{a_B} = \frac{r_A \alpha}{r_B \alpha} \)[/tex].
Notice that the angular accelerations cancel out since both disks have the same angular acceleration.
Thus, the ratio simplifies to [tex]\( \frac{r_A}{r_B} \)[/tex].
This ratio represents how many times larger the radius of disk A is compared to the radius of disk B.
For example, if [tex]\( r_A = 2r_B \)[/tex], then the linear acceleration of a point on the rim of disk A is twice that of disk B.
Therefore, the ratio of the linear acceleration of a point on the rim of disk A to the linear acceleration of a point on the rim of disk B is [tex]\( \frac{r_A}{r_B} \)[/tex].

Suppose an airline policy states that all baggage must be box shaped with a sum of length, width, and height not exceeding 162 in. what are the dimensions and volume of a square-based box with the greatest volume under these conditions
Final answer:
To find the dimensions and volume of a square-based box with the greatest volume under the given conditions, we need to maximize the volume. The dimensions of the box should be 54 inches by 54 inches by 54 inches, and the volume is 157,464 cubic inches.
Explanation:
The airline policy states that the sum of the length, width, and height of the baggage must not exceed 162 inches. To find the dimensions and volume of a square-based box with the greatest volume under these conditions, we need to maximize the volume of the box.
Let's assume the length, width, and height of the box are all equal to a. Therefore, the sum of the three dimensions is 3a.
According to the policy, 3a must not exceed 162 inches, so we have:
3a ≤ 162
a ≤ 54
Since the length, width, and height of a square-based box are all equal, a is the side length of the square base. Therefore, the dimensions of the box should be 54 inches by 54 inches by 54 inches, and the volume can be calculated as:
Volume = a³ = 54³ = 157,464 cubic inches.
