The maximum number of toothbrushes the dentist can purchase is 50.

Let's denote the number of toothbrushes the dentist orders by "x".

If the dentist orders less than 50 toothbrushes, then the cost of the toothbrushes will be 2.58x.

If the dentist orders 50 or more toothbrushes, then the cost of the toothbrushes will be 1.24x.

There is a base cost of [tex]$48[/tex] for printing the dentist's name and address on the toothbrushes.

The total cost of the order can be expressed as:

Total cost = 48 + (2.58x) for x < 50

Total cost = 48 + (1.24x) for x ≥ 50

The maximum number of toothbrushes the dentist can purchase, given that the budget is [tex]$110[/tex].

So we can set up an equation:

Total cost = 110

For x < 50:

48 + 2.58x = 110

2.58x = 62

x ≈ 24.03

For x ≥ 50:

48 + 1.24x = 110

1.24x = 62

x ≈ 50

The maximize number of toothbrushes, we choose the larger value of x, which is x ≈ 50.

One possible representation of such a vector is u = (3, 2), which has a magnitude of approximately 3.605 and makes an angle of about 33.69 degrees with the positive x-axis in the standard Cartesian coordinate system.

Firstly, it is important to understand the meaning of the double vertical bars (|| ||), which denote the magnitude or length of a vector. For instance, if we have a vector

=> v = (2, 3),

then its magnitude can be computed as

=>  ||v|| = √(2² + 3²) = √13.

Similarly, if we have a vector u = (u₁, u₂), then its magnitude can be expressed as

=>  ||u|| = √(u₁² + u₂²).

The given condition

=> ||-4u|| ≈ 14.42

can be rewritten as

=>  4||u|| ≈ 14.42

=>  ||u|| ≈ 3.605.

This means that the magnitude of vector u is approximately equal to 3.605.

Therefore, to obtain a possible representation of vector u with a magnitude of approximately 3.605, we can solve the following system of equations:

||u|| = √(u₁² + u₂²) ≈ 3.605

θ = tan⁻¹(u₂/u₁)

Note that there are infinitely many solutions to this system, since the direction of u is not uniquely determined.

However, one possible solution is u = (3, 2), which has a magnitude of

=> ||u|| = √(3² + 2²) = √13 ≈ 3.605

and makes an angle of

=> θ = tan⁻¹(2/3) ≈ 33.69 degrees

with the positive x-axis.

In geometry, a reflection is a type of transformation where a figure is flipped over a line, called the line of reflection. In this problem, ABC-A'B'C' is a reflection, which means that it is a transformation of a figure where each point of the original figure has a corresponding point in the reflected figure such that the line of reflection is the perpendicular bisector of the line segment joining each point to its corresponding point.

Probability of landing on space with polka dots = 3/8.

Probability of landing on space with stripes = 1/2.

Probability of landing on space with stripes and even numbers = 1/4.

Probability of landing on space with stripes or even numbers = 5/8.

Hence the code is 'AFCH'.

From the definition of Probability we know that,

Probability of event = (Number of Favorable outcomes)/(Total number of outcomes)

Here total number of spaces = 8.

Number of space with polka dots = 3 [space numbered 1, 4, 6]

Number of space with stripes = 4 [space numbered 0, 2, 3, 5, 7]

Number of space with stripes and even numbers = 2 [the space numbered 0 and 2]

Probability of landing on space with polka dots = 3/8 (A)

Probability of landing on space with stripes = 4/8 = 1/2 (F)

Probability of landing on space with stripes and even numbers = 2/8 = 1/4 (C)

So, Probability of landing on space with stripes or even numbers

= Probability of landing on space with polka dots + Probability of landing on space with stripes - Probability of landing on space with stripes and even numbers

= 3/8 + 1/2 - 1/4

= (3 + 4 - 2)/8

= 5/8 (H).

Based on the information given, the price of the zero coupon bond is $692.04.

To calculate the price of a zero coupon bond, we need to use the following formula:

[tex]\sf P =\dfrac{F}{1+r\div n}^{(nt)[/tex]

Where:

Also, the annual interest rate is 7.50%, which is the market interest rate, and the compounding is semiannual, which means n = 2. Finally, the time to maturity is 5 years.

Plugging in the values into the formula, we get:

[tex]\sf P = \dfrac{1000}{(1+0.075\div2)^{(2\times5)}}[/tex]

[tex]\sf P = \dfrac{1000}{(1.0375)^{10}}[/tex]

Answer:

80 points

Step-by-step explanation:

If score in English is x points and score in math is 5% higher then score in math

y = x + 0.05x

where 0.05 = 5% expressed as decimal

0.05x refers to the 5% increase in score

y = math score

y = x(1 + 0.05)

y = 1.05x

Given score in math = 84 this becomes

84 = 1.05x

x = 84/1.05

x = 80

So Emily's score in English was 80 points

The regular admission price for one adult is $17.50.

We have,

Let's first determine the total cost of admission after the coupons have been applied.

Since each person has a coupon for $5 off, the total discount for the group is $5 x 6 = $30.

The total cost of admission after the discount.

$105 - $30

= $75.

Let A be the regular admission price.

Since each person paid the same price after the discount, we can set up the following equation:

6(A - $5) = $75

We subtract $5 from the regular price A because that is the amount of the coupon discount.

We can simplify the equation as follows:

6A - $30 = $75

6A = $105

A = $17.50

Therefore,

The value of x in the quadrilateral is 70 degrees

To find the value of the fourth interior angle, we can use the fact that the sum of all four interior angles is equal to 360 degrees. We can set up an equation:

85 + 150 + 55 + x = 360

where x is the fourth interior angle we want to find. To solve for x, we can first simplify the left side of the equation by adding the known angles:

290 + x = 360

Then, we can isolate x by subtracting 290 from both sides:

x = 360 - 290

x = 70

Therefore, the value of x when the interior angles of the quadrilateral are 85, 150, and 55 degrees is 70 degrees. This means that the four interior angles of the quadrilateral are 85, 150, 55, and 70 degrees, and their sum is indeed equal to 360 degrees.
