Hence, 63 magazines were sold yesterday.

Carlos vendió la tercera parte de las manzanas que vendió Elisa, quien vendió 42 manzanas. Para determinar cuántas manzanas vendió Carlos, podemos calcular la tercera parte de 42.

La tercera parte de 42 se calcula dividiendo 42 entre 3:

42 / 3 = 14

Por lo tanto, Carlos vendió 14 manzanas.\(\)

Solving a linear equation we can see that Carlos sold 14 apples.

Here we know that Carlos sold one third of the amount that Elisa sold, so if we define the variables:

C = amount that Carlos sold.

E = amount that Elisa sold.

Then we can write the linear equation:

C = E/3

And we know that Elisa sold 42 apples, then we can replace that value to get:

C = 42/3 = 14

Carlos sold 14 apples.

One angle marked and one angle congruent as vertical

a. The two triangles PQU and PUT are congruent, and hence they have the same area.

b. Area of parallelogram PQRS = 70 cm square.

c. Area of parallelogram PQRS = area of triangle PQT. We know that U is the midpoint of QT.

Therefore, the length of the line segment PU and SQ are equal.

Thus, we can see that triangle PQS and PQU are on the same base PQ and between parallel lines PQ and SR. Area of triangle PQS = Area of triangle PQU + Area of triangle PQT Area of parallelogram PQRS = Area of triangle PQU + Area of triangle PQT { Area of parallelogram is equal to the sum of the areas of two triangles having the same base and between the same parallel lines}Area of parallelogram PQRS = area of triangle PQT.

d. d. To show that:

area of parallelogram PQRS = 4 x area of triangle VUT.

We know that PU and QT are the diagonals of the parallelogram PQRS. As we know that the diagonals of a parallelogram bisect each other.

Therefore, the line segment UV = TV.Now, triangles UTV and VUT are congruent.Area of triangle PQU = 2 × Area of triangle UTV.

Now, area of parallelogram PQRS = 2 × Area of triangle PQU Area of parallelogram PQRS = 2 × 2 × Area of triangle VUT Area of parallelogram PQRS = 4 × Area of triangle VUT.

Therefore, the area of parallelogram PQRS is 4 times the area of triangle VUT.

In the adjoining figure PQRS is a parallelogram and U is the midpoint of QT. Let us consider each question one by one:

a. Relation between the area of triangle PQU and PUT. The area of triangle PQU and PUT is equal. As U is the midpoint of QT, thus, the line segment PQ will also be divided into two equal parts.

Therefore, the two triangles PQU and PUT are congruent, and hence they have the same area.

b. If the area of triangle PUT is 35 cm square, then the area of parallelogram PQRS is 70 cm square Area of triangle PUT = 35 cm square

(Given)Now, both the triangles PQU and PUT have the same area. Thus, area of triangle PQU = 35 cm square Area of parallelogram PQRS = 2 × Area of triangle PQU { As PQU and PUT are congruent triangles, hence they have the same area}

Area of parallelogram PQRS = 2 × 35 cm square

Area of parallelogram PQRS = 70 cm square.

c. To prove that:

Area of parallelogram PQRS = area of triangle PQT. We know that U is the midpoint of QT.

Therefore, the length of the line segment PU and SQ are equal.

Thus, we can see that triangle PQS and PQU are on the same base PQ and between parallel lines PQ and SR. Area of triangle PQS = Area of triangle PQU + Area of triangle PQT Area of parallelogram PQRS = Area of triangle PQU + Area of triangle PQT { Area of parallelogram is equal to the sum of the areas of two triangles having the same base and between the same parallel lines}

Area of parallelogram PQRS = area of triangle PQT.

d. To show that:

area of parallelogram PQRS = 4 x area of triangle VUT.

We know that PU and QT are the diagonals of the parallelogram PQRS. As we know that the diagonals of a parallelogram bisect each other.

Therefore, the line segment UV = TV. Now, triangles UTV and VUT are congruent.Area of triangle PQU = 2 × Area of triangle UTV.

Now, area of parallelogram PQRS = 2 × Area of triangle PQU Area of parallelogram PQRS = 2 × 2 × Area of triangle VUT Area of parallelogram PQRS = 4 × Area of triangle VUT.

Therefore, the area of parallelogram PQRS is 4 times the area of triangle VUT.

Answer:

20 gallons

Step-by-step explanation:

The living room is made up of white trim and blue surface area between the walls. Since the ratio of the blue surface area between the walls to the white trim is given by 1 : 10.

Also 2 gallons of blue paints are used for the walls, let x represent the number of white paint used in gallons. Hence:

number of white paint in gallons = [1 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints

2 = 1/11  * total number of paints used

total number of paints  = 22 gallons

number of white paint (x) = [10 / (1 + 10)] * total number of paints = 1 / 11 * total number of paints

x = 10/11 * 22

x = 20 gallons

Therefore 20 gallons of white paint was used

c) Dilation 3 has a scale factor of 0 units.

What is a scale factor?

A scale factor is a number used to multiply the dimensions of a shape to enlarge or reduce its size. In geometry, the scale factor is used to create similar figures by preserving their shape while changing their size. If a figure is scaled up by a scale factor of 'k', its dimensions are increased by a factor of 'k'. If a figure is scaled down, its dimensions are reduced by a factor of 'k'.

For the triangle, the scale factor would be 3 units.

For the square, the scale factor would be 4 units.

For the line, the scale factor would be 0 units.

Hence,

a) Dilation 1 has a scale factor of 3 units.

4 Small Cans of Paint

Step-by-step explanation:

1/5 of the small can fills 1/4 of the paint sprayer.

That means we need to fill 3/4 of the can to completely fill it up.

We would need a total of 4 1/5ths to fill up the sprayer.

So one of the equations you could use is :

To find the measure of m∠5 in the given rectangle ABCD, we need to use the properties of rectangles.

In a rectangle, opposite angles are congruent. Therefore, m∠2 is equal to m∠4, and m∠1 is equal to m∠3. Since we are given that m∠2 is 40 degrees, we can conclude that m∠4 is also 40 degrees.

Now, let's focus on the angle ∠5. Angle ∠5 is formed by the intersection of two adjacent sides of the rectangle.

Since opposite angles in a rectangle are congruent, we can see that ∠5 is supplementary to both ∠2 and ∠4. This means that the sum of the measures of ∠2, ∠4, and ∠5 is 180 degrees.

Therefore, we can calculate the measure of ∠5 as follows:

m∠2 + m∠4 + m∠5 = 180

Substituting the given values:

40 + 40 + m∠5 = 180

Simplifying:

80 + m∠5 = 180

Subtracting 80 from both sides:

m∠5 = 180 - 80

m∠5 = 100 degrees

Hence, the measure of m∠5 in the rectangle ABCD is 100 degrees.

Passage B presents an argument by using logical reasoning to support its conclusion.

The first premise states, "If time is finite, then space is finite."

This premise establishes a relationship between the finiteness of time and the finiteness of space.

It suggests that if time has a definite endpoint, then space also has a definite limit.

The second premise states, "If time is infinite, then space is infinite." This premise establishes a different relationship,

implying that if time extends infinitely, then space also extends infinitely. It suggests that an infinite duration of time corresponds to an infinite expanse of space.

Based on these two premises, the conclusion follows logically: "Therefore, space is either finite or infinite."

This conclusion combines possibilities outlined in premises

and concludes that space must be either finite (if time is finite) or infinite (if time is infinite).

Passage B uses deductive reasoning to draw a conclusion from the given premises.

The direction angle of the vector v = 2i -6j is approximately 288.43 degrees.

What is a vector ?

In mathematics, a vector is a mathematical object that has both magnitude (length) and direction. Vectors are commonly used to represent physical quantities such as displacement, velocity, and force in physics and engineering, but they are also used in many other fields such as computer graphics, machine learning, and economics.

The direction angle of a vector is the angle it makes with the positive x-axis in the counterclockwise direction.

To find the direction angle, we first need to calculate the angle that the vector makes with the positive x-axis.

Using trigonometry, we can see that:

tan θ = (opposite side) / (adjacent side)

     = (-6) / 2

     = -3

Taking the inverse tangent of both sides, we get:

θ = tan⁻¹(-3)

Using a calculator, we find that:

θ ≈ -71.57°

However, since we are looking for the direction angle in the counterclockwise direction, we need to add 360 degrees to get the final answer:

θ = -71.57° + 360°

Thus, the direction angle of the vector v is approximately:

θ ≈ 288.43°

Therefore, the direction angle of the vector v = 2i -6j is approximately 288.43 degrees.

The decimal value of the 1's complement number 01110110 is 118.

The decimal value of the 1's complement number 10100111 is -83.

The decimal value of the 2's complement number 01011110 is 94.

The decimal value of the 2's complement number 10110011 is -179.

1's complement numbers:

a) Number: 01110110

To convert the positive 1's complement number to decimal, we can use the weighted sum method. Each bit in the binary number is multiplied by its corresponding weight (power of 2) and then summed up.

01110110 = (0 * 2⁷) + (1 * 2⁶) + (1 * 2⁵) + (1 * 2⁴) + (0 * 2³) + (1 * 2²) + (1 * 2¹) + (0 * 2⁰)

= 0 + 64 + 32 + 16 + 0 + 4 + 2 + 0

= 118

b) Number: 10100111

Similar to the previous example, let's determine the sign of the 1's complement number 10100111. The MSB is 1, indicating that this number is negative.

To convert a negative 1's complement number to decimal, we can again use the weighted sum method. However, in this case, we need to consider the sign and negate the result obtained from the weighted sum.

10100111 = -(0 * 2⁷) - (1 * 2⁶) - (0 * 2⁵) - (1 * 2⁴) - (0 * 2³) - (0 * 2²) - (1 * 2¹) - (1 * 2⁰)

= -0 - 64 - 0 - 16 - 0 - 0 - 2 - 1

= -83

2's complement numbers:

a) Number: 01011110

To find the decimal value of the 2's complement number 01011110, we'll follow a similar approach. First, we'll check the sign represented by the MSB. In this case, the MSB is 0, indicating a positive number.

To convert a positive 2's complement number to decimal, we can again use the weighted sum method, similar to the 1's complement. The only difference is that in 2's complement, we consider the MSB as a negative weight.

01011110 = (0 * 2⁷) + (1 * 2⁶) + (0 * 2⁵) + (1 * 2⁴) + (1 * 2³) + (1 * 2²) + (1 * 2¹) + (0 * 2⁰)

= 0 + 64 + 0 + 16 + 8 + 4 + 2 + 0

= 94

b) Number: 10110011

Finally, let's determine the decimal value of the 2's complement number 10110011. The MSB is 1, indicating that this number is negative.

To convert a negative 2's complement number to decimal, we'll again use the weighted sum method. However, since it's negative, we need to negate the result obtained from the weighted sum.

10110011 = -(1 * 2⁷) - (0 * 2⁶) - (1 * 2⁵) - (1 * 2⁴) - (0 * 2³) - (0 * 2²) - (1 * 2¹) - (1 * 2⁰)

To determine the probability that a student prefers the zoo or the water park, we need to know the total number of students and the number of students who prefer each option. Without this information, it is not possible to calculate the probability accurately.

To calculate the probability, we would need to divide the number of students who prefer the zoo or the water park by the total number of students. For example, if there are 50 students in total and 30 prefer the zoo and 20 prefer the water park, the probability would be:

First and foremost, it is important to note that human skin color is determined by a variety of factors, including genetics, environmental influences, and geographic location. In fact, skin color is the result of the amount and type of melanin pigment produced by specialized cells in the skin called melanocytes.

There are two main types of melanin pigment: eumelanin and pheomelanin. Eumelanin is responsible for producing darker skin colors, while pheomelanin produces lighter skin colors. However, the amount and distribution of these pigments can vary greatly between individuals, resulting in a wide range of skin tones.

Additionally, skin color can also be influenced by factors such as sun exposure, age, and hormonal changes. For example, prolonged sun exposure can lead to darker skin, while aging and hormonal changes can cause changes in skin pigmentation. Furthermore, it is important to note that skin color is not always clearly defined or easily categorized into specific shades. There can be a great deal of variation within a single skin tone, as well as overlap between different skin tones. This is due to the complex interplay of genetic and environmental factors that contribute to skin color.
