Explain how to compare 0.7 and 5/8.

Answers

Method #1: Convert everything to fractions and cross multiply to compare

0.7 turns into 7/10

So we need to compare 7/10 and 5/8 to see which is larger (or if they are equal). Let's assume for now that they are equal. So we have

7/10 = 5/8

Cross multiply to get

7*8 = 10*5
56 = 50

the left side is larger so we should update the equal sign to a "greater than" sign like so

56 > 50

Change the equal sign in the original problem to a "greater than" sign as well

7/10 > 5/8

So 0.7 is larger than 5/8

----------------------------------------------------------

Method #2: Convert everything to decimal form and compare

0.7 is already in decimal form
5/8 = 0.625 after using a calculator or long division

0.7 is the same as 0.700

Comparing 0.700 to 0.625 we see that 0.700 is larger (since 700 is larger than 625)

So 0.7 is larger than 5/8

ana made 12 rainbow loom bracelets in 3 hours. how many can she make in 15 hours

Answers

12 bracelets in 3 hrs.....12/3 = 4 bracelets per hr

in 15 hrs...
15 * 4 = 60 <=== she can make 60 bracelets
To solve this, we must see a ratio between 3 hours and 15 hours.

12/3=x/15
15 is 5 times larger than 3. Therefore, if we multiply 12 by 5, we will know how many bracelets Ana can make.

12×5= 60

Therefore, 60 bracelets can be made in 15 hours

A copy machine makes 44 copies per minute. how long does it take to make 154 copies?

YAY ANSWER change unit if needed.
WARNING I MIGHT BE WRONG IM STILL 14.

Final answer:

It takes 3.5 minutes for a copy machine to make 154 copies at a rate of 44 copies per minute.

Explanation:

To find out how long it takes for a copy machine to make 154 copies at a rate of 44 copies per minute, we need to perform a division calculation. First, we divide the total number of copies needed (154 copies) by the rate at which the machine produces copies, which is 44 copies per minute.

The calculation is as follows:

154 copies ÷ 44 copies per minute = 3.5 minutes.

This means it would take the copy machine 3.5 minutes to produce 154 copies.

How many factors does the algebraic expression 5xy have?

Answers

The algebraic expression 5xy has three factors: the number 5 and the variables x and y. Factors are the multiplicative components of an expression, and factoring involves breaking down expressions into these components.

The algebraic expression 5xy has three factors: the number 5, the variable x, and the variable y. A factor is a number, variable, or a product/quotient of numbers and/or variables separated by + or - signs.

When we are factoring, we are essentially reversing the distributive law and turning the expression into its multiple components, which can also be termed as factors or multiples. For instance, expressions like 5px, 5py, or similar expressions are all made up of factors that, when multiplied together, produce the value of the expression.

When addressing expressions that can be factored, such as ax² +2hxy+by² = 0, we look for expressions that, when evaluated, produce the same value. In this particular example, it can be factored into two linear factors and represents two straight lines intersecting at the origin.

Answer:

The algebraic expression [tex]\(5xy\)[/tex] has [tex]\(8\)[/tex] factors.

Explanation:

The algebraic expression [tex]\(5xy\)[/tex] can be factored as [tex]\(5 \times x \times y\)[/tex]. To find the number of factors, we count all the unique combinations of its prime factors:

- For the factor [tex]\(5\)[/tex], we have [tex]\(2\)[/tex] options: [tex]\(5\) or \(1\).[/tex]

- For the factor [tex]\(x\)[/tex], we have [tex]\(2\)[/tex] options: [tex]\(x\) or \(1\).[/tex]

- For the factor [tex]\(y\)[/tex], we have [tex]\(2\)[/tex] options: [tex]\(y\) or \(1\).[/tex]

Therefore, the total number of factors is the product of the options for each factor, which is [tex]\(2 \times 2 \times 2 = 8\)[/tex]. So, the algebraic expression [tex]\(5xy\)[/tex] has [tex]\(8\)[/tex] factors.

What is 6.666666667 as a improper fraction?

Answers

To convert 6.666666667 into an improper fraction, identify the whole number part and the repeating decimal part, which correspond to 18/3 and 2/3 respectively. Adding these together results in the improper fraction 20/3.

The questions asks how to express the decimal number 6.666666667 as an improper fraction. To convert a decimal to a fraction, we can identify the repeating part of the decimal, which in this case is '666...'. We know that repeating '6' corresponds to '2/3' in fraction form. To write it as an improper fraction, we first write the non-repeating part which is '6' as '6/1'. Then we add the repeating fraction '2/3' to it after converting '6/1' to have a common denominator of '3' which becomes '18/3'. Adding these gives us '20/3' which is the desired improper fraction.

To put this process into steps:

Identify 6 as the whole number part, which is equivalent to 6/1 or 18/3.Recognize that the repeating decimal .666... is equivalent to 2/3.Add 18/3 and 2/3 to get 20/3, which is the improper fraction form of 6.666666667.

What is the value of x?

A. 68°
B. 62°
C. 112°
D. 124

Answers

The triangle drawn in the question shows a small single line drawn across two sides of the triangle.

This means that those two sides are equal in length.

Hence, the triangle is an isosceles triangle.

In isosceles triangles, the angles opposite to the equal sides are also equal.

Hence, we know that the two angles other than x is 56°.

The sum of the interior angles of a triangle is 180°

x + 56 + 56 = 180

x = 180 - 56 - 56

x = 180 - 112

x = 68°

Hence, the answer is A.
If a triangle has two sides where they are the same length, then the base angles are both the same degrees.

So, we know the other base angle is also 56°.

We also know that all triangles' interior angles add up to 180°.

We will build an equation to solve for x.

56 + 56 + x = 180

Solve for x.

56 + 56 + x = 180
112 + x = 180 <-- Combine like terms
x = 68

So, we know that x is equal to 68 degrees.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at

x = 0.

Given, a line passes through origin (0, 0) and point (2, 4).

So slope is = (y₂ - y₁)/(x₂ - x₁) = (4 - 0)/(2 - 0) = 2.

Let the required equation of the line be y = mx + b.

∴ 4 = 2×2 + b.

b = 0.

So, the equation is y = 2x + 0 ⇒ y = 2x.

Shyam invested money in the stock market

Answers

Given that question: Shyam invested money in the stock market. In the first year, his stock increased 20%. He paid his stock broker $300 and then lost $450. He withdrew $500, and then his remaining investment doubled. Shyam’s investment is now worth $7100. How much was Shyam’s original investment?

The solution is as follows:

Let the amount Shyam invested in the stock market be x, then in the first year his stock increased by 20% giving 1.2x.

He paid his stockbrocker $300 to have 1.2x - $300 left, and he lost $450 to have 1.2x - $300 - $450 = 1.2x - $750 left.

He withdrew $500 to have 1.2x - $750 - $500 = 1.2x - $1,250 left.

His remaining investment doubled to have 2(1.2x - $1,250) = 2.4x - $2,500

Shyam's investment is now worth $7,100 which means that
2.4x - $2,500 = $7,100
2.4x = $7,100 + $2,500 = $9,600
x = $9,600 / 2.4 = $4,000

Therefore, the value of Shyam's original investment is $4,000

The area of a rectangle is 440 square inches. The length of the rectangle is 29 inches more than its width. What is the length of the rectangle?

Answers

The length of regtangle is 40 inches

the length of the rectangle is either -11 inches or 40 inches.

Let the length of the rectangle be L.Let the width of the rectangle be W.

Given the following data;

Area of rectangle = 440 square inches

Translating the word problem into an algebraic equation, we have;

[tex]L = W + 29[/tex]

To find the length of the rectangle;

Mathematically, the area of a rectangle is given by the formula;

[tex]Area = L * W[/tex]

Substituting the values into the formula, we have;

[tex]440 = (W + 29) * W\\\\440 = W^{2} + 29W[/tex]

Rearranging the equation, we have;

[tex]W^{2} + 29W - 440 = 0[/tex]

W e would solve the quadratic equation by factorization;

[tex]W^{2} + 40W - 11W - 440 = 0\\\\W(W + 40) - 11(W + 40)\\\\(W + 40)(W- 11)[/tex]

Width, W = -40 0r 11 inches.

Next, we would find the length of the rectangle;

When Width, W = -40;

[tex]L = W + 29[/tex]

[tex]L = -40 + 29[/tex]

Length, L = -11 inches

When Width, W = 11;

[tex]L = W + 29[/tex]

[tex]L = 11 + 29[/tex]

Length, L = 40 inches

Therefore, the length of the rectangle is either -11 inches or 40 inches.

A total of 308 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was three times the number of adult tickets sold. how many adult tickets were sold?

Answers

77 bilhetes de adultos
231 bilhetes de estudantes

Follow below steps;

The student is asking how many adult tickets were sold for a school play if a total of 308 tickets were sold and the number of student tickets sold was three times the number of adult tickets sold. To solve this problem, we will use algebra to set up an equation.

Let's define x as the number of adult tickets sold. Since the number of student tickets is three times that amount, we can say that 3x represents the number of student tickets sold. The total number of tickets sold is the sum of adult and student tickets, which is given by the equation x + 3x = 308.

To find the value of x, we combine like terms:

x + 3x = 4x4x = 308x = 308 \/ 4x = 77

Therefore, the number of adult tickets sold was 77.

A countable quantitative variable that is finite is called a discrete variable while a non finite or infinite quantitative variable is known as a continuous variable. Discrete variables can only be a certain set of numbers while a continuous variable can be any number of values.

A quantitative variable with a countable number of values is known as a discrete variable, which includes whole number counts such as the number of yellow M&Ms or total M&Ms in a sample

A quantitative variable that has a finite or countable number of values is called a discrete variable. Quantitative discrete data such as the number of phone calls received each day can only take certain numerical values, which are typically integers like zero, one, two, or three. This is different from continuous data, which can take any value within a certain range, like weight or percentage values that can include fractions and decimals.

For example, in the case of counting M&Ms, the number of yellow M&Ms and the total number of M&Ms would be discrete data because they can only be whole numbers. In contrast, the weight of the M&Ms in ounces and the percentage that are red are examples of continuous data because these can take on any value, including fractions, within the range.

The distinction between discrete and continuous data is important for selecting appropriate statistical methods for analysis, as certain methods are more suitable for discrete data, while others are better for continuous data
