Answer:

The price of the hats is $ 10, the price of the masks is $ 5 and the price of the T-shirts is $ 15.

Step-by-step explanation:

A system of equations is a set of two or more equations with several unknowns in which you want to find a common solution.

In other words, a  system of linear equations is a system of equations in which each equation is linear. A solution of a system is an assignment of values ​​for the unknowns that makes  each of the equations is true, so solving a system means finding all the solutions of the system.

In this case you apply a system of equations. So you first determine the system variables:

You know that Jose purchased 2 hats, 3 masks, and 1 t-shirt for  $50. This is:

2*x + 3*y + 1*z=50 Equation (A)

You know that Hannah purchased 1 hat, 2 masks, and 2 t-shirts for $50. This is:

1*x + 2*y + 2*z=50 Equation (B)

You know that Amarria purchased one of each item for $30. This is:

1*x + 1*y + 1*z=30 Equation (C)

The system of equations is formed by equations (A), (B) and (C).

The method of reduction consists of adding (or subtracting) the equations to each other to eliminate one of the unknowns. Sometimes, it is necessary to multiply the equations by some number so that, when adding them, one of the unknowns disappears.

In this case you apply the method to calculate the value of z. Subtracting (A) - (B) - (C) you get:

(2-1-1)*x + (3-2-1)*y + (1-2-1)*z= 50-50-30

Solving:

0*x + 0*y + (-2)*z=-30

(-2)*z=-30

\(z=\frac{-30}{-2}\)

z=15

Remembering that z represents the price of the t-shirts, then each has a value of $ 15.

Replacing the value of z in equation (A):

2*x + 3*y + 1*15=50

you get:

2*x + 3*y= 50 - 15

2*x + 3*y=35 Equation (D)

Replacing the value of z in equation (B):

1*x + 2*y + 2*15=50

1*x + 2*y + 30= 50

1*x + 2*y= 50- 20

1*x + 2*y= 20 Equation (E)

The substitution method consists of choosing an equation and solving one unknown in terms of the other unknown. Then you must substitute the expression found in the other equation, to obtain an equation with an unknown, and then solve that unknown. Finally, you substitute the value found in the previously found expression to solve for the remaining unknown.

Solving for the variable x from Equation (E) you get:

x= 20- 2*y Equation (F)

Replacing in Equation (D), you get:

2*(20-2*y) + 3*y=35

Solving:

2*(20) + 2*(-2)*y + 3*y= 35

40 - 4*y + 3*y=35

- 4*y + 3*y=35 - 40

(-1)*y= -5

\(y=\frac{-5}{-1}\)

y=5

Remembering that y represents the price of the masks, then each has a value of $ 5.

Finally, replacing the value of y in equation (F) you get:

x=20 - 2*5

x= 20-10

x=10

Remembering that y represents the price of the hats, then each has a value of $ 10.

In summary, the price of the hats is $ 10, the price of the masks is $ 5 and the price of the T-shirts is $ 15.

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

Answer:

38.66 meters.

Step-by-step explanation:

Let's denote the height of the building as 'h' (to be determined). Given that the tower is 30m high, we can use trigonometry to solve for the height of the building.

From the information provided, we can form a right triangle with the height of the tower as one side, the height of the building as another side, and the distance between the tower and the building as the hypotenuse.

Considering the angle of depression of 30 degrees, we have the following equation:

tan(30°) = h / d

Where 'd' is the distance between the tower and the building. We don't have the exact value of 'd,' but we can use the second angle of depression to find the relationship between 'd' and the height of the tower.

Using the angle of depression of 45 degrees, we have:

tan(45°) = 30 / d

We can rearrange this equation to solve for 'd':

d = 30 / tan(45°)

Now we can substitute this value of 'd' into the first equation:

tan(30°) = h / (30 / tan(45°))

To find the value of 'h,' we can solve this equation:

h = (30 / tan(45°)) * tan(30°)

Using a calculator, we can calculate the value of 'h' to be approximately 38.66 meters.

Therefore, the height of the building is approximately 38.66 meters.

It is instructed that we change 44.0 gallons to liters. One gallon is one unit of volume. A gallon is equivalent to 3.785 liters.

3.785411784 litres make to one US gallon. 4 quarts, 8 pints, or 128 fluid ounces make up a gallon. In American measurements, a gallon is equivalent to 3.785 litres, 128 fluid ounces, 4 quarts, 8 pints, or 16 cups. A gallon's volume is about equivalent to 3.78541 litres. Thus, a gallon is more than three litres. A gallon of one liquid could weigh differently than a gallon of another. As one imperial gallon is equal to 4.54609 litres, it takes up space that is nearly 4,546 cubic centimetres (roughly a 16.5cm cube). An average glass holds eight ounces. So, 16 eight-ounce glasses of water make up a gallon.

The absolute minimum value is -824 and the absolute maximum value is 181.

The absolute maximum and absolute minimum values of f(x) = 5x3 - 9x2 - 108x + 1 on the interval (-3, 4] can be found using the following steps:

1. Take the derivative of f(x): f'(x) = 15x2 - 18x - 108.

2. Set f'(x) equal to zero and solve for x: 15x2 - 18x - 108 = 0.

Factoring out 3, we get 3(5x2 - 6x - 36) = 0.

Solving for x using the quadratic formula, we get x = -2.4 or x = 3.

3. Evaluate f(x) at the critical points and endpoints of the interval (-3, 4]:

f(-3) = -824,

A line graph is the most basic method of illustrating data.

A line graph is a special type of graph that is frequently employed in statistics. In relation to another quantity, it shows how one quantity has changed. For instance, we may use this graph to illustrate how the cost of various chocolate flavors fluctuates. Typically, a two-dimensional XY plane is used to plot this variation. A graph is said to be linear if it can represent the relationship between any two measurements by a straight line. Consequently, a line graph is often known as a linear graph.

The three different types of line graphs are simple line graphs, numerous line graphs, and compound line graphs.

The dimensions of the lightest open-top right circular cylindrical can that will hold a volume of 1331 cm³ are a radius of √(1331/π) cm and a height of 2√(1331/π) cm.

The volume V of a right circular cylindrical can is given by V = πr²h, where r is the radius and h is the height of the can. We are given that the volume of the can is 1331 cm³.

To find the dimensions of the lightest can, we need to minimize the surface area of the can, which corresponds to minimizing the sum of the lateral surface area and the top surface area. Since the can is open-top, we can ignore the bottom surface area.

The lateral surface area A of a right circular cylindrical can is given by A = 2πrh, and the top surface area is given by A_top = πr².

By substituting the volume equation into the lateral surface area equation, we can express the lateral surface area as A = 2V/h.

To minimize the surface area, we need to minimize the sum of A and A_top. Since A_top = πr², we can rewrite the sum as A_total = 2V/h + πr².

To find the dimensions that minimize A_total, we can differentiate A_total with respect to r and h, set the derivatives equal to zero, and solve the resulting equations. However, since we are only interested in the dimensions, we can substitute the given volume and radius into the equations and simplify.

By substituting V = 1331 cm³ and r = √(1331/π) cm, we find that h = 2√(1331/π) cm.

Therefore, the dimensions of the lightest open-top right circular cylindrical can that will hold a volume of 1331 cm³ are a radius of √(1331/π) cm and a height of 2√(1331/π) cm.

The result of the normal probability distribution being bell-shaped is that the mean, median, and mode are at the center.

This means that the center of the bell-shaped curve represents the most likely occurrence of the data and that the values are symmetrically distributed around the mean.

The mean, median, and mode of a normal distribution are equal, which means that they are all located at the center of the bell-shaped curve. This is an important characteristic of the normal distribution and sets it apart from other distributions where the mean, median, and mode may not be equal.

In a normal distribution, the area on each side of the mean does not equal 1.00, but rather approaches 1.00 as the curve becomes more symmetrical. The height of the curve at the mean represents the highest probability of occurrence, and the probabilities decrease as the values deviate from the mean.
