Martina made 3 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 3 necklaces was $11.10 . If the beads cost $1.80 for each necklace, how much did each pendant cost?

Answer:

The interest earned on the account would be $30.75. (6150.053/12=30.75)

Step-by-step explanation:

The Pythagorean Theorem states that the square of the lengths of the two sides of a right triangle adds to the square of the length of the hypotenuse.

The Pythagorean Theorem states that a ² +b ² =c ² for a right-angled triangle ABC, right-angled at B. The whole integers a, b, and c form a Pythagorean triple if a and b are the lengths of the two sides of a right-angled triangle with hypotenuse c.

Draw a BD that is perpendicular to AC and meets at D. So, the Pythagorean theorem is established. Recall that the Pythagorean Theorem only applies to right-angled triangles. Two even numbers and one odd number, or all odd numbers, cannot form a Pythagorean triple. The square of an odd number is an odd number, and the square of an even number is an even number, hence this is true. A, B, and C are the three positive integers, and the Pythagorean triples are written as            a ² +b ² =c ².

The total clay required is 376.2 cm³and area to be painted is given by 300.7 cm²

The volume of a Right Circular Cylinder. In general, the volume of a right cylinder is the area of the base times the height of the cylinder. The area of the circular base is given by the formula A = πr2. Substitute to get V = πr2h.

Given here: The dimensions of the edge of the cube as 5cm and the cylinder diameter is 4cm with a height of 20cm

We know the volume of the cube is given by a³ where a is the measure of the length of the cube

Thus a³=5³

            =125 cm³

and surface area of the cube is given by 6a²=6×25

                                                                          =150 cm²

Again the volume of the cylinder and surface area of the given cylinder is as follows:

Volume= 22/7×2²×20

            =251.2 cm³

surface area = 2·π·2·10+2·π·22≈150.79645cm²

Thus the clay required to make the toy is=125+251.2

                                                                    =376.2 cm³

And the area to be painted is given by =150.7+150

                                                                 =300.7 cm²

Hence, The total clay required is 376.2 cm³and area to be painted is given by 300.7 cm²

The exact probability that this museum gets at least 3 visitors in a minute is approximately 0.224

A Poisson distribution is a probability distribution that models the number of times an event occurs within a given time or space, if these events are rare and independently of the time since the last event. The Poisson distribution is characterized by the mean number of occurrences λ in a given interval.

In this case, the mean number of visitors per minute is λ = 5 visitors / 2 minutes = 2.5 visitors per minute.

We can use the Poisson probability mass function to find the probability that this museum gets at least 3 visitors in a minute.

To find the probability that this museum gets at least 3 visitors in a minute by using:

1 - P(X < 3)

Where X is the number of visitors in a minute and 3 is the lower limit of the number of visitors we want to include in the sample.

Thus, P(X>=3) = 1 - P(X < 3) = 1  - 0.776 = 0.224

(14cos45° + 70cos180°, 14sin45° + 70sin180°) = (17.9, -55.1) is the component form of the sum of u and v with direction angles u and v.

The amount of rotation that occurs between two planes or straight lines is what is meant to be meant by the geometrical term "angle." A full circle is 360 degrees, and an angle is measured in degrees. Right angles (90 degrees), acute angles (less than 90 degrees), and obtuse angles (more than 90 degrees) are the most prevalent types of angles. Depending on how they relate to one another, angles can also be broken down into complementary or supplementary categories. The sum of complementary and supplementary angles is 90 degrees, while the sum of the two is 180 degrees.

The vector addition formula can be used to determine the component form of the sum of u and v. According to this formula, the direction angle of the vector sum is equal to the arctangent of the ratio of the sum of the y-components of the two vectors to the sum of the x-components of the two vectors, while the magnitude of the vector sum of two vectors is equal to the square root of the sum of the squares of each vector's magnitude.

The component form of the sum of the given vectors u and v is as follows:

Magnitude = √(14²) + (70²)) = 70.45

The direction angle is arctan((14 × sin(45) + 70×sin(180)) / (14×cos(45) + 70×cos(180)))

The outside temperature t when Arianna ate breakfast was 55°F.

An equation is a mathematical statement showing that two expressions are equal. It is written with an equal sign (=) between two expressions, with one expression on the left side of the equal sign, and the other expression on the right side.

According to the given statements-  

Let the outside temperature at the time of breakfast be t°F.

The temperature dropped by 20°F by the time of dinner.

So the temperature at the time of breakfast = t - 20

Also, when she ate dinner the temperature was 35°F

So the equation for outside temperature t when Arianna ate breakfast will be -

t - 20 = 35

Ivanna earns $2,400 if she doesn't sell any copies of history is fun.

Ivanna makes an extra $120 ($120) for each additional copy she sells and a loss of $120 ($120) for each fewer copy.

If Ivanna doesn't sell any copies of History is Fun, her total compensation is $2,400.

Ivanna makes a total salary of y = 2,400 + 120x, where x is the quantity of copies of her book History is Fun she sells.

We compare the compensation for two successive values of y to determine the change in Ivanna's pay.

We must estimate y when x exists of consecutive values i.e. 1, 2, 3, 4

We compute the value of y when x = 1, 2 and 3.

When x = 1, y = 2,400 + 120 (1) = 2,400 + 120 = $2,520.

When x = 2, y = 2,400 + 120 (2) = 2,400 + 240 = $2,640.

When x = 3, y = 2,400 + 120 (3) = 2,400 + 360 = $2,760.

To estimate the increase in her pay for a copy, we subtract y when x = 2 from y when x = 3.

(y when x = 3) - (y when x = 2) = $2,760 - $2,640 = $120.

So for every extra copy, Ivanna gets an extra $120.

To estimate the decrease in her pay for a copy, we subtract y when x = 3 from y when x = 2.

(y when x = 2) - (y when x = 3) = $2,640 - $2,760 = -$120.

So for every less copy, Ivanna loses $120.

To estimate her pay when she doesn't sell any copies of history is fun, we substitute the value of x as 0 in y.

When x = 0, y = 2,400 + 120 (0) = $2,400.

So Ivanna earns $2,400 if she doesn't sell any copies of history is fun.

The complete question is:

Answer:  The graph of the function f(x) = -2x² is a parabola that opens downward, with its vertex at the origin (0,0). The x-axis is the axis of symmetry for this parabola.

To plot five points on the graph of the function, we can substitute different x-values into the function and solve for y:

For x = 0, y = f(0) = -2(0)² = 0

For x = -2, y = f(-2) = -2(-2)² = 8

For x = -3, y = f(-3) = -2(-3)² = 18

For x = 2, y = f(2) = -2(2)² = -8

For x = 1, y = f(1) = -2(1)² = -2

So, the five points on the graph of the function are (0,0), (-2,8), (-3,18), (2,-8), (1,-2).

It's important to note that, the graph of f(x)=-2x² will be a parabola opening downward and passing through the points that we found.
