Answer:

55% of the whole wall is covered in paint of any color.

Step-by-step explanation:

To determine what percentage of the wall is covered in paint, we need to add the fractions of the wall covered by each color of paint and then convert the result into a percentage.

Red paint: 1/5

Blue paint: 1/10

Green paint: 1/4

First, we need to find a common denominator, which is the least common multiple (LCM) of the denominators 5, 10, and 4. The LCM of 5, 10, and 4 is 20. Now, we can convert the fractions to equivalent fractions with a denominator of 20:

Red paint: (1/5) * (4/4) = 4/20

Blue paint: (1/10) * (2/2) = 2/20

Green paint: (1/4) * (5/5) = 5/20

Now, add the fractions:

Total paint coverage = 4/20 + 2/20 + 5/20 = (4 + 2 + 5)/20 = 11/20

To convert this fraction to a percentage, we can divide 11 by 20 and multiply the result by 100:

(11/20) * 100 = 0.55 * 100 = 55%

Thus, 55% of the whole wall is covered in paint of any color.

Answer:

Yes, Alexa is correct.

Step-by-step explanation:

Counting by 8 means adding 8 repeatedly. The first multiple of 8 is 8 (1 x 8), the second multiple is 16 (2 x 8), the third multiple is 24 (3 x 8), the fourth multiple is 32 (4 x 8), and the fifth multiple is 40 (5 x 8). So, by counting by 8 five times, Alexa can find the fifth multiple of 8 which is 40.

Using factors, we can conclude that the new product will be 48 time more than the old product.

In mathematics, the factor of a number is a divisor of the inputted integer that entirely divides it, leaving no residue. We can use a variety of techniques, including the division method and the multiplication method, to identify a number's components.

Let the product be P.

Let the numbers be a and b.

Now,

P = a × b

According to the question.

Let a is increased by a factor of 12 and b by 4:

P = 12a × 4b

P = 48 × a × b

Hence, we can conclude that the product will increase by a factor of 48.

The monthly interest yield on Tom's retirement account for a 30-year period would be $637.71.

Assuming that the interest is compounded monthly, the monthly yield on Tom's retirement account with an APR of 4.57% for a 30-year period can be calculated using the formula:

Monthly Yield = (Principal × Monthly Interest Rate) ÷ (1 - (1 + Monthly Interest Rate[tex])^{(-Number of Months)}[/tex]

Here, Principal = $160,000

APR = 4.57%,

Number of Months = 30 years ÷ 12 months/year = 360 months.

First, we need to convert the APR to a monthly interest rate by dividing it by 12:

Monthly Interest Rate = 4.57% × 12

Monthly Interest Rate = 0.3808%

Monthly Yield = (160000 × 0.3808%) ÷ (1 - (1 + 0.3808%[tex])^{-360}[/tex]

Monthly Yield = $637.71

Answer: X= -4

Step-by-step explanation:

The quadratic function that models the height h of the ball after t seconds in flight is h(t) = -16t² + 70t + 3.5

A quadratic function is a type of function in algebra that involves a variable raised to the power of 2, or squared. The general form of a quadratic function is:

f(x) = ax² + bx + c

where f(x) represents the output of the function for a given input x, a, b, and c are constants that determine the shape and position of the function, and x is the input variable.

The graph of a quadratic function is a parabola, which is a curved shape that opens upwards if the coefficient a is positive, and downwards if the coefficient a is negative. The vertex of the parabola is the point at which the function reaches its minimum or maximum value, depending on the direction of the opening of the parabola. The x-coordinate of the vertex is given by:

x = -b/2a

The height h of the ball after t seconds in flight can be modeled by the quadratic function:

h(t) = -16t² + vt + s

where v is the initial velocity of the ball, s is the initial height of the ball, and -16 is the acceleration due to gravity in feet per second squared.

In this case, we know that the ball is hit with an initial velocity of 70 ft/s and is 3.5 ft off the ground, so we can substitute these values into the equation:

h(t) = -16t² + 70t + 3.5

Therefore, the quadratic function that models the height h of the ball after t seconds in flight is:

h(t) = -16t² + 70t + 3.5

Note that this function is only valid until the ball reaches its maximum height and starts falling back down to the ground.

Erin's capital gains are the sum of her long-term capital gains (LTCG) and short-term capital gains (STCG), which is $2,600 + $24,400 = $27,000.

Erin's capital losses are the sum of her long-term capital losses (LTCL) and short-term capital losses (STCL), which is ($9,600) + ($15,600) = ($25,200).

Since Erin's capital gains exceed her capital losses, she has a net capital gain of $27,000 - $25,200 = $1,800.

Answer: $5.40

Step-by-step explanation:

First, let's calculate the tax for each purchase and then find the total amount paid by Dave and James.

For Dave:

Basketball cost = $15

Tax = 8% of $15 = 0.08 * 15 = $1.20

Total amount paid by Dave = Cost + Tax = $15 + $1.20 = $16.20

For James:

Football cost = $20

Tax = 8% of $20 = 0.08 * 20 = $1.60

Total amount paid by James = Cost + Tax = $20 + $1.60 = $21.60

Now, let's find the difference between the amounts paid by Dave and James.

Difference = Amount paid by James - Amount paid by Dave = $21.60 - $16.20 = $5.40

So, the difference in the amounts paid by Dave and James, including tax, is $5.40.

Step-by-step explanation:

In order to find the f(x) or y value, you have to replace x with the given one in the table:

x = -1,

.

x = 6,

[tex]y = \sqrt[3]{ 6 - 7} = \sqrt[3]{ - 1} = - 1[/tex]

.

x = 7,

[tex]y = \sqrt[3]{7 - 7} = \sqrt[3]{0} = 0 [/tex]

x = 8,

[tex]y = \sqrt[3]{8 - 7} = \sqrt[3]{1} = 1 [/tex]

If TV cable company has 2400 subscribers who are each paying ​$16 per month, charging $52 per month will yield a maximum revenue of $98,304.

To find the rate that will yield the maximum revenue, we can use the formula:

r = -b / 2a

where r is the rate, a is the coefficient of the quadratic term, and b is the coefficient of the linear term in the revenue equation.

The revenue equation is:

R = (2400 + 120x)(16 - 0.5x)

Expanding and simplifying, we get:

R = -0.5x^2 + 52x + 38400

So, a = -0.5 and b = 52. Plugging these values into the formula, we get:

r = -52 / 2(-0.5) = 52

This means that the company should charge $52 per month to maximize revenue. To find the maximum revenue, we can plug this value into the revenue equation:

R = (2400 + 120(52))(16 - 0.5(52)) = $98,304

a) P(correct) = 1/6 b) P(incorrect) = 5/6 c) P(correct) = 1/3 d) P(incorrect) = 2/3.

What is probability?

Probability is a measure of the likelihood or chance that a particular event will occur. It is a way of quantifying uncertainty, and is expressed as a number between 0 and 1, where 0 represents an event that is impossible, and 1 represents an event that is certain.

What are events in probability?

In probability, an event refers to an outcome or a set of outcomes of a random experiment or a process. A random experiment is an experiment or a process that has multiple possible outcomes, and the outcome of the experiment is uncertain or unpredictable.

a) The probability of selecting the correct choice from six possible choices is 1 out of 6, or 1/6, since there is only one correct answer among the six options.

b) The probability of selecting an incorrect choice from six possible choices is 5 out of 6, or 5/6, since there are five incorrect answers among the six options.

c) If three choices can be eliminated, then there are only three options left, with one correct answer among them. Therefore, the probability of selecting the correct choice from the remaining options is 1 out of 3, or 1/3.

d) Similarly, if three choices can be eliminated, then there are three options left, with two incorrect answers among them. Therefore, the probability of selecting an incorrect choice from the remaining options is 2 out of 3, or 2/3.
