Armando opened a new savings account with an initial deposit if $250. Which combination will result in a zero balance in armandos account?

Answers

Answer 1

A zero balance in Armando's account can be achieved by subtracting $250 from the account balance. This can be done through a combination of withdrawals and/or transfers out of the account.

What is subtracting?

Subtracting is a mathematical operation that involves taking one number away from another. It is the inverse of addition, and is represented by the minus sign (-). Subtracting is used to determine the difference between two numbers, or to reduce a number by a given amount. In algebraic terms, subtracting is represented by the equation: a - b = c, where a is the starting number, b is the number to be subtracted, and c is the resulting difference. Subtracting can also be used on fractions, decimals, and other forms of numbers.

For example, Armando could make a $250 withdrawal from the account or transfer $250 to another bank account.

Under certain conditions, sound can travel 768 miles per hour. Under these conditions, Alan hears thunder 45 seconds after seeing lightening. His friend, Ryan hears thunder after seeing the same lightening in 30 seconds. What is the longest and the shortest possible distance that Alan and his friend are apart.

Answers

The shortest possible distance between Alan and Ryan is 11,250 miles, and the longest possible distance is 12,000 miles

What is distance?

Distance is a numerical measurement of how far apart two objects or points are. It is a scalar quantity, meaning that it has magnitude but no direction. Distance is usually measured in units such as meters, kilometers, miles, or feet, depending on the system of measurement used.

What is sound?

Sound is a type of physical energy that is produced by vibrating objects and travels through a medium, such as air, water, or solids, as a series of pressure waves. When an object vibrates, it creates a disturbance in the surrounding medium that causes molecules to move back and forth, creating areas of high and low pressure that propagate outward from the source of the sound.

In the given question,

Let d be the distance between Alan and Ryan in miles. Then, the time it takes for sound to travel this distance is given by d/768. Therefore, we have:

d/768 = 45 - 30 = 15

Solving for d, we get:

d = 15 x 768 = 11520

So the distance between Alan and Ryan is 11520 miles.

If we take the lower bound of 750 miles per hour, we can calculate the minimum distance between Alan and Ryan as follows:

d/750 = 15

d = 15 x 750 = 11250

Therefore, the minimum distance between Alan and Ryan is 11250 miles.

If we take the upper bound of 800 miles per hour, we can calculate the maximum distance between Alan and Ryan as follows:

d/800 = 15

d = 15 x 800 = 12000

Therefore, the maximum distance between Alan and Ryan is 12000 miles.

Therefore, the shortest possible distance between Alan and Ryan is 11,250 miles, and the longest possible distance is 12,000 miles.

What will be the population in 2040?

ANSWER: people

Answers

Answer: In 2030, the population will be 16,800 and in 2040 the population will be 18,816.

Step-by-step explanation: To find the population in 2030, we need to calculate one decade of growth from 2020 to 2030:

Population in 2030 = 15,000 x (1 + 0.12)^1 = 16,800

Therefore, the population in Gastonia is expected to be 16,800 in 2030.

To find the population in 2040, we need to calculate two decades of growth from 2020 to 2040:

Population in 2040 = 15,000 x (1 + 0.12)^2 = 18,816

Therefore, the population in Gastonia is expected to be 18,816 in 2040.

Boolean expressions that are equivalent to the expression num ≥ 15 are (B) (num > 15) OR (num = 15) and (D) NOT (num < 16).

In Boolean algebra, a Boolean expression is an algebraic expression made up of Boolean variables and logical operations. Boolean logic deals with logical variables and has only two values: 1 or 0 or TRUE or FALSE. Boolean expressions evaluate to a Boolean value of either 0 or 1 or TRUE or FALSE.(A) (num > 15) AND (num = 15) - this expression is not equivalent to num ≥ 15 because (num > 15) is false for all values of num that are less than or equal to 15.

However, num ≥ 15 is true for all values of num that are greater than or equal to 15.(C) NOT (num < 15) - this expression is not equivalent to num ≥ 15 because NOT (num < 15) is true for all values of num that are greater than or equal to 15. However, num ≥ 15 is true for all values of num that are greater than or equal to 15.(B) (num > 15) OR (num = 15) - this expression is equivalent to num ≥ 15 because if num is greater than 15, then (num > 15) is true and (num = 15) is false. However, if num is equal to 15, then (num > 15) is false and (num = 15) is true.

In either case, (num > 15) OR (num = 15) is true, which means that num ≥ 15 is true.(D) NOT (num < 16) - this expression is equivalent to num ≥ 15 because if num is less than 16, then (num < 16) is true and NOT (num < 16) is false. However, if num is greater than or equal to 16, then (num < 16) is false and NOT (num < 16) is true. In either case, NOT (num < 16) is true, which means that num ≥ 15 is true.

Suppose that 6 out of the 19 doctors in a small hospital are General Practitioners, 5 out of the 19 are under the age of 40 , and 2 are both General Practitioners and under the age of 40. What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 40

Answers

The probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 from a small hospital is 9/19, given 6 out of 19 are General Practitioners, 5 out of 19 are under 40, and 2 are both.

To find the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40, we need to add the probabilities of these two events and subtract the probability of selecting a doctor who is both a General Practitioner and under the age of 40, since we don't want to count that case twice:

P(General Practitioner or under 40) = P(General Practitioner) + P(Under 40) - P(General Practitioner and under 40)

we know 6 out of 19 doctors are General Practitioners, 5 out of 19 doctors are under the age of 40, 2 doctors are both General Practitioners and under the age of 40.

Therefore:

P(General Practitioner) = 6/19

P(Under 40) = 5/19

P(General Practitioner and under 40) = 2/19

Substituting these values into the formula:

P(General Practitioner or under 40) = 6/19 + 5/19 - 2/19

= 9/19

Therefore, the probability of randomly selecting a doctor who is either a General Practitioner or under the age of 40 is 9/19.

The coordinates of the endpoints of PQ are P( – 12,7) and Q( – 4, – 9). Point R is on PQ and divides it such that PR:QR is 3:5

Answers

The coordinates of R are (-8,-1). To find the coordinates of R, we first need to find the length of PQ.

Using the distance formula, we have:

d(P,Q) = √((x2-x1)² + (y2-y1)²)

= √((-4-(-12))² + (-9-7)²)

= √(8² + (-16)²)

= √(320)

= 8 √(5)

Since PR:QR is 3:5, we can set up the following equation:

d(P,R)/d(R,Q) = 3/5

Let the coordinates of R be (x,y). We can use the midpoint formula to find the coordinates of the midpoint of PQ, which is also the coordinates of the point that divides PQ into two parts in the ratio of 3:5.

Midpoint of PQ = ((-12-4)/2, (7-9)/2) = (-8,-1)

Using the distance formula again, we can find the distance between P and R:

d(P,R) = (3/8) d(P,Q)

= (3/8) (8 √(5))

= 3 √(5)

Now we can use the ratio PR:QR = 3:5 to find the distance between R and Q:

d(R,Q) = (5/3) d(P,R)

= (5/3) (3 √(5))

= 5 √(5)

Finally, we can use the midpoint formula to find the coordinates of R:

x = (-12 + (3/8) (8))/2 = -8

y = (7 + (-1))/2 = 3

The margins at the top and bottom of the poster are 2 inches, and the margins on the left and right are 1 inch. Let us suppose the width of the poster is x in and the length of the poster is y in. Also, we need to find the least amount of poster used.Therefore, the dimensions of the poster be x in × y in. The printable area of the poster is given as 450 sq in. Hence, the area of the poster minus the area of the margins should be 450 sq in. Therefore,x × y = (x - 2) (y - 4) + 450x × y = xy - 2x - 4y + 8 + 450xy - xy - 2x + 4y = 8 + 450(y - 4)x = (450(y - 4) - 8) / (y - 1)x = (450y - 1808) / (y - 1)Now we need to calculate the dimensions of the rectangular poster. We need to find the value of x and y. Substituting the value of x in the first equation we get,y = (450 / (x - 2)) + 4We also know that x > 2 and y > 4. We need to minimize the amount of poster used.

We have to find the minimum number, k, of z in (a, b) such that g'(z) = 0. The function g is continuous on the interval [a, b] and is differentiable on (a, b). Suppose that g(x) = 0 for 4 distinct values of x in (a, b).

Let x1, x2, x3, and x4 be the four distinct values of x such that g(x) = 0.Now consider the following cases:Case 1: All four x1, x2, x3, x4 are local extrema of g(x).If this is the case, then g′(x1)=g′(x2)=g′(x3)=g′(x4)=0. Therefore, the minimum number, k, of z in (a, b) such that g′(z) = 0 is 4.Case 2:

There are less than four local extrema of g(x).In this case, by Rolle's Theorem, there exists at least one point z in (a, b) such that g′(z)=0. Since there are less than four local extrema of g(x), this point z is not equal to any of x1, x2, x3, and x4. Therefore, the minimum number, k, of z in (a, b) such that g′(z) = 0 is 1.In conclusion, the minimum number, k, of z in (a, b) such that g′(z) = 0 is either 1 or 4 depending on whether there are less than four local extrema of g(x) or all four x1, x2, x3, and x4 are local extrema of g(x).

240,000 grams
24,000 grams
2,400 grams
240 grams

Answers

Answer: 24000 g

Step-by-step explanation:

multiply together:

4 bags * 6 kg = 24 kg total

convert:

1 kg = 1000 g

24 kg * (1000 g / 1 kg) = 24000 g

To calculate the total mass of the box in grams, we need to first calculate the total mass of the 4 bags of sugar in kilograms, and then convert that to grams.

The mass of one bag of sugar is 6 kilograms.

The total mass of all 4 bags is:

4 bags x 6 kilograms/bag = 24 kilograms

To convert 24 kilograms to grams, we multiply by the conversion factor of 1000 grams/kilogram:

24 kilograms x 1000 grams/kilogram = 24,000 grams

Therefore, the total mass of the box, including all 4 bags of sugar, is 24,000 grams.

The correct answer is B) 24,000 grams.

use a direct proof to show that every odd integer is the difference of two squares. [hint: find the difference of the squares of k 1 and k where k is a positive integer.]

Answers

Yes, every odd integer can be written as the difference of two squares.

To prove this, let k be a positive integer. Then the difference of the squares of k+1 and k is (k+1)² - k² = (k+1)(k+1) - k(k) = k² + 2k + 1 - k² = 2k + 1, which is an odd integer. Thus, every odd integer can be written as the difference of two squares.

To prove this, we first chose a positive integer, k. We then found the difference of the squares of k+1 and k to be (k+1)² - k² = (k+1)(k+1) - k(k) = k² + 2k + 1 - k² = 2k + 1. Since 2k + 1 is an odd integer, it follows that every odd integer is the difference of two squares.

assistants please --------> The members of a weight loss support group just collectively weighed in at 1,519 pounds, which is 2% lighter than their previous weight. How much did the group weigh last time?

Answers

Answer:  1550 pounds

Work Shown:

x = previous total weight

2% of x = 0.02x = amount of weight lost

x - 0.02x = 0.98x = current total weight

0.98x = 1519

x = 1519/0.98

x = 1550 pounds

Check:

2% of 1550 = 0.02*1550 = 31

The group collectively lost 31 pounds.

1550-31 = 1519

The answer is confirmed.

Note that 98% of 1550 = 0.98*1550 = 1519

a display shelf in a retail shop will showcase the stores handmade artisan soaps. the length of the shelf given to each bar of soap will be uniformly distributed with a mean of 3 inches and a standard deviation of 0.5 inch. for 50 bars of soap what is the probability the length of the display will exceed 154 inches?

Answers

The probability the length of the display will exceed 154 inches is 0.1292

What is the probability?

The probability that the length of the display shelf given to each bar of soap will exceed 154 inches when there are 50 bars of soap is 0.0062 or 0.62%. This is because the mean is 3 inches and the standard deviation is 0.5 inches, which means that the length of the display will have a normal distribution.

We can calculate this probability by using the following formula:

P(x > 154) = P (x > 154 - 50 × 3/√(50×0.5)) = P(Z > 1.13) = 1 - P(Z < 1.13) = 1 - 0.870 = 0.1292

The probability the length of the display will exceed 154 inches is 0.1292.

Answers

The answer to the question is 334 kittens.

Given that a cat gave birth to 333 kittens who each had a different mass between 147 g and 159 g. Then the cat gave birth to a 4th kitten with a mass of 57 g.

First of all, we will find out the range of the mass of kittens. The range is given as follows;Range = Maximum Value - Minimum Value Range = 159 g - 147 g Range = 12 g

Now, the cat gave birth to a 4th kitten with a mass of 57 g, we can say that the minimum value of kitten's mass is 57 g.So, the maximum value of kitten's mass can be calculated as follows;Maximum Value = 57 g + Range Maximum Value = 57 g + 12 g Maximum Value = 69 g Now, we can say that all kittens with a mass of 69 g or less would be born because the minimum value of kitten's mass is 57 g and the range of mass is 12 g.

Therefore, the answer to the question is 334 kittens.
