Answer:

Step-by-step explanation:

The answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

A combination of numbers, variables, and operators that represents a quantity or mathematical relationship is called an expression.

First, divide sextillion (10²¹) by nonmillion (10⁶) to get 10¹⁵.

Next, multiply 10¹⁵ by 10,000 to get 10¹⁹.

Subtract 200 million (2 x 10⁸) from 10¹⁹ to get 9.9998 x 10¹⁸.

Finally, add 5,000 to get the result of approximately 9.9998 x 10¹⁸ + 5,000 = 9.9998 x 10¹⁸ + 0.0005 x 10¹⁸ = 9.9998 x 10¹⁸.

Therefore, the answer to this arithmetic expression is approximately 9.9998 x 10¹⁸

Answer: C. g

Step-by-step explanation:

Answer:

Caroline gets 4*5 = 20 pounds

Colin gets 9 * 4     = 36 pounds

Sarah gets 6*4      = 24 pounds.

Step-by-step explanation:

The ratios are 5x + 9x + 6x

5x + 6x = 11x

Caroline and Sarah get a total of 44 pounds. They don't get 44 pounds each.

11x = 44            Divide by 11

x = 44/11

x = 4

Colin gets 9x

x = 4

9*4 = 36

Colin gets 35 pounds.

Caroline gets 4*5 = 20 pounds

Colin gets 9 * 4     = 36 pounds

Sarah gets 6*4      = 24 pounds.

Caroline and Sarah get 20 + 24 = 44

If Arturo lives in colorado, which has a state income tax rate of 4.63% and he earns $1,345 biweekly, then the amount of state income tax withheld from each of his paychecks is equal to $62.27.

The state income tax withheld from each of his paychecks can be determined by the percentage formula;

P% × x = y

Here,

P% is the state income tax rate

x is the dollars earned biweekly

y = state income tax withheld from each of his paychecks

As the state income tax rate is equal to 4.63% and the amount earned biweekly is equal to $1345, therefore;

P% × x = y

4.63% × 1345 = y

4.63% can be converted into decimal form as follows,

4.63% = 4.63 / 100 = 0.0463

Therefore,

0.0463 × 1345 = y

y = 62.27

Hence, the state income tax withheld from each of his paychecks is calculated to be $62.27

A $560 investment compounded annually at a rate of 9% per year will take approximately 7.97 years to double, resulting in a final amount of $1,120.

To determine how long it will take for the investment to double, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount

P is the principal amount (initial investment)

r is the annual interest rate (as a decimal)

n is the number of times the interest is compounded per year

t is the number of years

In this case, the initial investment (P) is $560, the annual interest rate (r) is 9% (0.09 as a decimal), and the final amount (A) is $1,120 (double the initial investment).

Plugging in these values, we have:

1,120 = 560(1 + 0.09/n)^(n*t)

To solve for t, we need to choose a value for n. Since compounding is done annually, we can set n = 1:

1,120 = 560(1 + 0.09/1)^(1*t)

1,120 = 560(1 + 0.09)^t

Dividing both sides by 560:

2 = (1 + 0.09)^t

Taking the logarithm of both sides:

log(2) = t * log(1 + 0.09)

Solving for t:

t = log(2) / log(1.09)

Using a calculator, we find:

t ≈ 7.97 years

Therefore, it will take approximately 7.97 years (rounded to 2 decimal places) for the investment to double.

Distributive property is the term for breaking a larger number apart into smaller numbers that can be multiplied together to get a specific result.

Firstly, to distribute means to divide something or give a share or part of something.

Distributive property explains that multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Therefore, distributive property is the term for breaking a larger number apart into smaller numbers that can be multiplied together to get a specific result.

The equations of the lines are y = 3x - 5 and y = (1/2)x - 7

An equation is an expression that shows how numbers and variables are related to each other.

A linear function is in the form:

y = mx + b

Where m is the rate of change and b is the initial value

Two lines are parallel if they have the same slope

1) y = 3x + 6; (4, 7)

The parallel line would have a slope of 3 and pass through (4, 7), hence:

y - 7 = 3(x - 4)

y = 3x - 5

2) y = (1/2)x + 5; (4, -5)

The parallel line would have a slope of 1/2 and pass through (4, -5), hence:

y - (-5) = (1/2)(x - 4)

y = (1/2)x - 7

Answer:

See Below.

Step-by-step explanation:

We are given the two functions:

\(\displaystyle f(x) = x^2 + 5x \text{ and } g(x) = 4x - 7\)

9)

We want to find:

\(f(x) + g(x)\)

Substitute:

\(\displaystyle = (x^2 + 5x) + (4x - 7)\)

And combine like terms. Hence:

\(f(x) + g(x) = x^2 + 9x - 7\)

10)

We want to find:

\(f(x) - g(x)\)

Substitute:

\(= (x^2 + 5x) - (4x - 7)\)

Distribute:

\(= (x^2 + 5x) + (-4x +7)\)

And combine like terms. Hence:

\(f(x) - g(x) = x^2 +x +7\)

11)

We want to find:

\(\displaystyle f(x) \cdot g(x)\)

Substitute:

\(\displaystyle = (x^2 + 5x)(4x-7)\)

Expand:

\(\displaystyle = 4x(x^2 + 5x) - 7(x^2 + 5x) \\ \\ = (4x^3 + 20x^2) + (-7x^2 -35x) \\ \\ = 4x^3 + 13x^2 - 35x\)

Hence:

\(\displaystyle f(x) \cdot g(x) = 4x^3 + 13x^2 - 35x\)

12)

We want to find:

\(g(x) - f(x)\)

Substitute:

\(= (4x -7) - (x^2 + 5x)\)

Distribute:

\(= (4x-7) + (-x^2 - 5x)\)

And combine like terms. Hence:

\(\displaystyle g(x) - f(x) = -x^2 -x -7\)

J in 55min

Alternative method

The trick is to convert the numbers you are given to numbers that you can add together.

You have minutes per pool. You can’t work with that. But if you take the reciprocal of each you get pools per minute.

So if the first hose fills 1/55 = 0.01818 pools per minute and the second one fills 1/45 = 0.0222 pools per minute, then both of them will fill 0.1818 + 0.0222 = 0.04040 pools per minute. If we take the reciprocal of that we end up with 1/0.04040 = 24.75 minutes per pool.

The type of random variable in this scenario is a geometric random variable. Its parameter is the probability of failure for each integrated circuit being tested.

The type of random variable you're dealing with in this scenario, where you are testing integrated circuits in sequence until you find the first failure, is called a Geometric Random Variable. This type of random variable represents the number of trials needed for the first success (or failure, in this case) in a series of independent Bernoulli trials with the same probability of failure. The parameter for a Geometric Random Variable is the probability of failure, denoted as p. In summary, the type of random variable in this problem is a Geometric Random Variable, and its parameter is the probability of failure (p).
