A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

To figure out what fraction of the toys are blue, we need to convert all of the fractions to have a common denominator.

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

Looking at the fractions, we can see that there are 3 fractions, [tex]\frac{1}{8}, \frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex].

To solve for the common denominator between [tex]\frac{1}{8}[/tex] and [tex]\frac{3}{5}[/tex], we first multiply the denominators, 8 and 5.

We now know that the denominator is going to be 40.

To get the numerators, we can use these equations:

The new fractions look like this:

To easily convert the last fraction ([tex]\frac{1}{4}[/tex]) we can multiply the numerator and denominator by 10.

We multiply by 10 because the denominator, which is 4, can be multiplied by 10 to get our common denominator of 40.

Now, we have our 3 fractions converted to have common denominators.

([tex]\frac{5}{40}, \frac{24}{40}[/tex] and [tex]\frac{10}{40}[/tex])

(Yellow, red, and green)

We can now add these up and see what fraction of blue is remaining.

Therefore, the fraction of blue toys compared to the total amount is [tex]\frac{1}{40}[/tex].

If there are 100 green toys resulting in [tex]\frac{10}{40}[/tex] of all the toys, we can divide 100 by 10 to get the number of blue toys.

We divide by 10 because [tex]\frac{1}{40}[/tex] is only [tex]\frac{1}{10}[/tex] of [tex]\frac{10}{40}[/tex], meaning we divide by 10.

Therefore, there are 10 blue toys.

Answer:

1/4=100

10/40=100

40/40=400

1/8=400/8=50

3/5=400/5*3=240

400-100-50-240=10

10 of the toys are blue

The equation for Harper's situation is 10x = 150 + 5x. The number of t-shirts Harper needs to sell so that the amount of money she spends to start her business and the amount of money she earns are the same is 30 t-shirts.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The price of one plane t-shirt is = $5

The money spent on printing equipment is = $150

The price for printed t-shirt is = $10

Let the number of t-shirts to be sold be x.

The expression for earning money is 10x

The amount she spends on starting the business is -

150 + 5x

So, according to question the equation is -

10x = 150 + 5x

10x - 5x = 150

5x = 150

x = 150 / 5

x = 30

Therefore, 30 t-shirts needs to be sold.

The abbreviation BODMAS aids kids in recalling the hierarchy of mathematical operations (the correct order for solving math problems). The acronym BODMAS is made up of the following terms: B Bracket, O Degree (Power/Exponent or Root), D Division, M Multiplication, A Addition, and S Subtraction. BODMAS is also referred to as PEDMAS in some locales. This symbolizes exponents, division, multiplication, addition, and subtraction. It also represents parentheses. The BODMAS rule states that parentheses must be handled first, followed by powers or roots (i.e., of), divisions, multiplications, additions, and lastly subtractions. While he is known as BODMAS in India and the UK, PEMDAS is primarily utilized in the US. However, they are identical to one another. The parentheses, order, and order of the operations of addition, subtraction, multiplication, and division are the same for the two rules.

The corresponding values are -

f(-1) = -6, f(0) = -5, f(1) = 6, f(2) = 3.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The graph for function y = f(x) is given.

The collection of input or argument values for which a function is actual and defined is known as its domain.

In the graph it can be seen that the graph is intersecting x-axis at x = -2 and at x = 2.

So, the domain is (-2,2]. The ( symbol denotes empty circle whereas the ] symbol denotes a filled circle.

A function's range is the collection of values for which the dependent variable is defined.

The coordinates for the ending of the graph is (2,3). So, the range of the function is [-2,3].

The value for f(-1) as seen in the graph is -

x = -1, then y = -6.

The value for f(0) as seen in the graph is -

x = 0, then y = -5.

1. The algae blooms was larger initially is the first algae.

2. The first algae bloom is decreasing more quickly than the second algae bloom.

1. To determine which algae bloom was larger initially, we can compare the values of the functions at d=0.

For the first algae bloom, we have A(0) = 200.

For the second algae bloom, we have B(0) = 100*27⁰ = 100.

Therefore, the first algae bloom was larger initially.

2. To determine which algae bloom is decreasing more quickly, we can compare the rates of decrease of the two functions. The rate of decrease is given by the derivative of the function, which tells us how fast the area is changing with respect to time.

For the first algae bloom, we have A'(t) = -20e^(-0.2t).

For the second algae bloom, we have B'(d) = -100*27^(-1)d.

To compare these rates of decrease, we can evaluate them at the same point in time or days. Let's evaluate them at d=1, which means one day has passed since the first measurement.

For the first algae bloom, we have A'(1) = -20e^(-0.2) ≈ -15.24.

For the second algae bloom, we have B'(1) = -100*27^(-1) ≈ -3.70.

Therefore, we can see that the first algae bloom is decreasing more quickly than the second algae bloom. This is because the rate of decrease of the first bloom is more negative than the rate of decrease of the second bloom.

You can deduce from your facts that assertion A is correct. Statement B is not conclusive. Statement C is incorrect. Statement D is not conclusive. statement E is false.

The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.

Here,

From your data, you can conclude that:

A. A parent-offspring regression for trait C will have the highest slope.

Heritability is the proportion of variation in a trait that can be explained by genetic variation. A higher heritability indicates that more of the variation in a trait is due to genetic differences, and less is due to environmental differences. If the heritability of a trait is 0.8, this means that 80% of the variation in the trait is due to genetic differences, and a parent-offspring regression would have a steeper slope than if the heritability was lower.

B. Selection of trait A will have no effect on the population mean for this trait.

This statement cannot be concluded from the data. Heritability of a trait does not dictate the responsiveness of a trait to selection. Even if the heritability of a trait is low, it can still respond to selection, and even if the heritability of a trait is high, it may not respond much to selection, depending on the presence of other factors such as the distribution of the trait in the population, the presence of linkage disequilibrium, and the presence of genetic constraints.

C. A parent-offspring regression for trait B will be a flat line.

This statement is false. If the heritability of a trait is 0.5, this means that half of the variation in the trait is due to genetic differences, and half is due to environmental differences. A parent-offspring regression would not be a flat line, but would still have a slope, albeit not as steep as if the heritability was higher.

D. Selection on each behavior will result in similar changes in the population mean for each trait.

This statement cannot be concluded from the data. Heritability is only one of many factors that affects the responsiveness of a trait to selection, and the responsiveness of each trait will depend on other factors as well.

E. A parent-offspring regression on trait A will have a slope of 0.9.

This statement is false. Heritability is the proportion of variation in a trait that can be explained by genetic differences, not the slope of a regression. The slope of a parent-offspring regression would depend on other factors such as the distribution of the trait in the population and the presence of environmental factors.

Step-by-step explanation:

Scientific notation is written in the form [tex]a \times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one non-zero digit to the left of the decimal point.

The number of times you have moved the decimal point is the power of 10 (the value of n).

Therefore, to convert 0.000000032 to scientific notation, move the decimal point 8 places to the right so that [tex]a[/tex] is 3.2.

As the decimal point has been moved 8 places the right, the exponent of 10 is -8.

Answer:

Therefore, you will need to order approximately 9.07 cubic yards of topsoil to fill the garden to a depth of 6 inches.

Step-by-step explanation:

To calculate the amount of topsoil needed, we need to find the volume of the garden in cubic yards, since topsoil is sold by the cubic yard.

The garden is 35 feet by 14 feet and 6 inches (or 0.5 feet) deep.

Volume of the garden = length x width x depth

= 35 feet x 14 feet x 0.5 feet

= 245 cubic feet

To convert cubic feet to cubic yards, we divide by 27 (since 1 cubic yard = 27 cubic feet):

Volume in cubic yards = 245 cubic feet / 27

= 9.07 cubic yards (rounded to two decimal places)

Therefore, you will need to order approximately 9.07 cubic yards of topsoil to fill the garden to a depth of 6 inches.

Answer:

Step-by-step explanation:

PART A: No, the trinomial 4x^3 + 28x + 49 is not a perfect square trinomial. To be a perfect square trinomial, the first and last terms must be perfect squares and the middle term must be twice the product of the square roots of the first and last terms. In this case, the first and last terms are not perfect squares, and the middle term is not twice the product of the square roots of the first and last terms.

PART B: To factor the expression 6x^2 + 5x - 4, we need to find two binomials whose product is equal to this expression.

First, we can break down the coefficient of x into two numbers whose product is 6 * (-4) = -24 and whose sum is 5. These numbers are 8 and -3.

Next, we use these two numbers to split the middle term 5x into two terms:

6x^2 + 8x - 3x - 4

We can now factor the expression by grouping:

(6x^2 + 8x) - (3x + 4)

2x(3x + 4) - 1(3x + 4)

(2x - 1)(3x + 4)

Therefore, the area of the rectangle can be factored as (2x - 1)(3x + 4).

To determine the dimensions of the rectangle, we set each factor equal to one of the dimensions and solve for the other dimension:

2x - 1 = length

3x + 4 = width

Alternatively, we could switch the factors and get the same answer:

2x - 1 = width

3x + 4 = length

Either way, these are the dimensions of the rectangle, expressed in terms of x.

finance charge Jack will​ pay is $1,512.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, Jack Fitzgerald wishes to purchase a used car that has a cash price of ​$11,000. The installment terms include a down payment of ​$2,000 and 48 monthly payments of ​$219.

a)

The amount that needs to be financed is = 11,000 - 2,000 = $9,000.

Amount repayment = 219 x 48 = $8,100.

=> Finance charge = Amount repayment - Amount needs to be financed

Finance charge = 10512 - 9000

Finance charge = 1,512$

b)

We apply the PV for annuity formula to find the interest rate per one month denoted as i:

Amount needs to be finance = (equal monthly installment x i) / [ 1 - (1+i)^-36 ]

or 9,000 = (219/i) x [1 - (1+i)^-48 ] <=> i = 0.911%.
