Using equations to solve the word problem, the first child withdrew $700, second child withdrew $1500, and third child withdrew $1250.

A word problem is a mathematical exercise that requires the student to read and understand a narrative description of a problem, identify the mathematical quantities involved, and then formulate and solve an equation to find the solution. Word problems often involve real-world scenarios such as shopping, money, and time.

Let's define our variables;

We can proceed to write linear equations with our variables

1/2x = 1/4y ...eq(i)

z = 500 + x ...eq(ii)

From equation (i)

x = 1/2y

z = 500 + 1/2 y

x = 750

x = 1/2(y)

750 = 0.5y

y = 750 * 2

y = 1500

z = 500 + x

z = 500 + 750

z = 1250

The first child took out $750, the second child took out $1500, and the third child took out $1250.

On solving the question we can say that the , plot the equation by points in the graph to get the line in the graph.

Equations with graphs as the unknowns are known as graph equations. The concept of isomorphism is one of the key issues in graph theory. When are two graphs identical, we inquire? Different graph equations may be used to express the aforementioned graphs.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is utilized. A lot of specialists, such as air traffic controllers, architects, computer programmers, and carpenters, employ equations on a daily basis.

The first seven terms of the Fibonacci sequence are: 0, 1, 1, 2, 3, 5, 8, 105, 225.

Sequence is an ordered arrangement of elements, usually numbers or objects, which follows a specific pattern. It is a mathematical concept that is used in a variety of areas, such as computer science, data analysis, and number theory. A sequence can be finite, like the first 10 numbers in the counting sequence, or it can be infinite, such as the set of natural numbers. It is important to understand the concept of a sequence in order to be able to use it in various areas.

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding numbers, starting from 0 and 1.

The Fibonacci sequence is named after mathematician Leonardo Fibonacci, who introduced the sequence in his book Liber Abaci in 1202.

The sequence is also known as the Golden ratio, because the ratio of successive numbers in the sequence converges on the Golden ratio of 1.618. The first seven terms of the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, and the fourth and sixth terms of the sequence are 105 and 225 respectively.

Answer:c

Step-by-step explanation:

Four numbers forming a geometric sequence such that the second term is 35 less than the first term and the third term is 560 more than the fourth term are -35/3, -140/3, - 560/3, -2240/3 and 7, -28, 112, - 448  

Four numbers forming a geometric sequence can be calculate as follows

these terms: a₁, a₂, a₃, a₄

a₁ = a₂ + 35

a₃ = a₄ + 560

Use the formula for the n-term:

a₂ = a₁r

a₃ = a₁r²

a₄ = a₁r³

replace

a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35

a₁r² = a₁r³ + 560  ⇒ a₁(1 - r)r² = 560

Subtracting from the first equation to  the second:

r² = 560/35

r² = 16

r = √16

r = ± 4

Use the first equation to find the first term:

a₁( 1 ± 4) = 35

1. a₁ = 35/-3 = -35/3

2. a₁ = 35/5 = 7

We have two sequences:

r = 4

-35/3, -140/3, - 560/3, -2240/3

r = -4

The value of y for the given conditions is 82.2.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Given a phrase, y divided by 6.85=1.2

y ÷ 6.85 = 12

y/6.85 = 12

multiply both sides by 6.85

y/6.85(6.85) = 12 x 6.85

y = 82.2

In order to have length twice width the answer should be 28 feet.

Let x be the width of the garden.

The length of the garden is 2x.

The perimeter of a rectangle is equal to 2(length + width)

So 42 = 2(2x + x)

42 = 2(3x)

x = 14

The width of the garden is 14 feet and the length is 2x = 2(14) = 28 feet.

The answer is 28 feet (Option a).

Answer:

Radius =21,  height = 45  
Lateral Surface Area = [tex]5937.61[/tex] cm²
Total Surface Area = [tex]8708.49[/tex]  cm²

Radius = 28, height =28
Lateral Surface Area =  [tex]4926.01[/tex] cm²

Total Surface Area  =  [tex]9852.03[/tex] cm²

Step-by-step explanation:

If r is the radius of a cylinder with height h

Lateral surface area

[tex]L = 2\pi rh[/tex]

Top and bottom surface area for each which is a circle is [tex]\pi r^2[/tex]

So total bottom and top surface area = [tex]2 \pi r^2[/tex]

Total surface area =

[tex]2\pi rh + 2\pi r^2 = 2\pi r(h + r)[/tex]

For r = 21, h = 45
[tex]L = 2 \pi \cdot 21 \cdot 45 = 1890 \pi = 5937.61 \;cm^2[/tex]

[tex]T = 2\pi \cdot 21 (21 + 45) = 2772 \pi = 8708.4948\;cm^2[/tex]

For r = 28, h = 28

[tex]L = 1568\pi = 4926.01 cm^2[/tex]

The particles contain 5.199 mol. The result is obtained by dividing the number of particles by the Avogadro number.

Avogadro number is the number of particles contained in 1 mol of any substance. It is 6.022 × 10²³ particles/mol.

Where

The number of particles of a substance is 3.131 × 10²⁴ particles. Find the number of moles!

With the Avogadro number, the number of moles would be

N = n × NA

3.131 × 10²⁴ = n × 6.022 × 10²³

n = (3.131 × 10²⁴) / (6.022 × 10²³)

When two numbers are multiplied or divided, there is a proportionate relationship. Although a linear equation frequently includes a proportional component in addition to some constant number, a linear relationship can also be proportional.

A relationship is proportionate if its graph is a line or ray that passes through the origin. It is not proportionate if the line or ray does not go through the origin. Additionally, something is not proportionate if it is not linear.

As shown in the graph, the straight line passed through the origin which means that it is a proportional relationship.

The probability that Sheila is late on any one day is 0.295 or 29.5%.

We can use the law of total probability to find the probability that Sheila is late on any one day.

The law of total probability states that for any event B, the probability of event B occurring can be calculated by summing the probability of event B occurring given that event A has occurred, multiplied by the probability of event A occurring. Symbolically, this can be represented as:

P(B) = P(B|A1) * P(A1) + P(B|A2) * P(A2) + ... + P(B|An) * P(An)

In this case, event B is Sheila being late, and events A1 and A2 are Sheila walking or cycling to school, respectively. The probabilities of these events occurring are:

P(A1) = 0.65 (the probability that Sheila walks to school)

P(A2) = 0.35 (the probability that Sheila cycles to school, since 1- 0.65)

P(B|A1) = 0.4 (the probability that Sheila is late given that she walks to school)

P(B|A2) = 0.1 (the probability that Sheila is late given that she cycles to school)

Plugging these values into the equation gives:

P(B) = P(B|A1) * P(A1) + P(B|A2) * P(A2) = 0.4 * 0.65 + 0.1 * 0.35 = 0.26 + 0.035 = 0.295

So the probability that Sheila is late on any one day is 0.295 or 29.5%.

Aspect ratio refers to the proportion of the width to the height of a rectangular image or screen. It is commonly represented as two numbers separated by a colon, such as 4:3 or 16:9.

An aspect ratio of 1:3 means that the width of the image or screen is one-third of its height. This aspect ratio is not commonly used for standard images or screen sizes but it can be used for special cases such as vertical videos.

In general, for images and videos, the aspect ratio of 4:3 was used in the past, but now the aspect ratio of 16:9 is more common, and it's the standard aspect ratio used in most modern televisions, computer monitors, and digital cameras.

Also, it's worth noting that the aspect ratio of 1:3 represents a very elongated shape, and it's not suitable for most practical uses, as it would not be able to display most standard content without black bars on the top and bottom of the screen.
