Answer:

Hi friend! The answer is D. 10

I hope this helps!

Answer:

B) 10

Step-by-step explanation:

Assign variables to each person:

A=Alina's Age

M=Amy's Age

G=Greg's Age

Set up a system of equations given the information:

A=6+G

M=2.5A

M=40

Notice that M is already given, so we can plug that into the second equation:

40=2.5A

16=A

So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:

16=6+G

10=G

So Greg is 10 years old, therefore B is the correct answer.

Step-by-step explanation:

It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

What is the percentage increase?

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original.

It is generally better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

This is because the percentage raise you receive is applied to your current salary. If you receive a 3% raise first, your salary will be higher when you receive the 9% raise, so the 9% raise will be applied to a higher base salary. This means that you will receive a larger increase in salary overall if you receive the 9% raise first.

For example, let's say you are currently making $50,000 per year. If you receive a 3% raise followed by a 9% raise, your salary would increase to $51,500 after the first raise and then to $56,365 after the second raise, for a total increase of $6,365.

On the other hand, if you receive a 9% raise followed by a 3% raise, your salary would increase to $54,500 after the first raise and then to $56,365 after the second raise, for a total increase of $5,865.

In this example, you would receive a larger increase in salary overall if you received the 9% raise first. This is because the 9% raise is applied to a lower base salary, resulting in a larger increase in salary overall.

Of course, the actual amount of the raise will depend on your current salary and the percentage of the raise. In general, though, it is usually better to receive a larger percentage raise first, followed by a smaller percentage raise.

Hence, It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

Answer:

Firstly we will divide all 8 marbles into 2 sections. Each section contains 4 marbles.

Then we balance each section and find that one section is lighter than other.

Then we take lighter section and further divide it into 2 sections and each section contains 2 marbles.

Then we balance them again and we find the lighter section further divide it into 2 sections and each section contains 1 marble, balance them and we get the lightest marble.

What is number line?
A number line is a representation of a graduated straight line in elementary mathematics that serves as a visual representation of the real numbers. It is assumed that every point on a number line corresponds to a real number, and that vice versa. Frequently, the integers are represented by specially marked, uniformly spaced points on a line. The line includes all real numbers, continuing indefinitely in both directions, as well as numbers that are in between the integers, even though the image only displays the integers from -3 to 3. It is frequently employed as a teaching tool, particularly when teaching simple addition and subtraction with negative numbers.

The required probability is approximately 0.603 or 60.3%.

Given, In a shipment of 65 vials, only 12 do not have hairline cracks.

Therefore, number of vials having hairline cracks

= 65 - 12 = 53

We need to find the probability that all 2 of the selected vials have hairline cracks.

Here, both vials need to have hairline cracks.

Therefore, the probability can be found as follows:

Probability of selecting the first vial with a hairline crack = Number of vials with hairline crack / Total number of vials

= 53/65

Probability of selecting the second vial with a hairline crack,

given that the first vial had a hairline crack = Number of vials with hairline crack / Total number of remaining vials

= 52/64

Simplifying both the above expressions,

Probability of selecting 2 vials with hairline cracks

= (53/65) x (52/64)= 0.603

Approximately, the probability of selecting 2 vials with hairline cracks is 0.603 or 60.3%.

Hence, the required probability is approximately 0.603 or 60.3%.

Step-by-step explanation:

match the denominators so have 6/30 be multiplies with 40/40 and 12/40 multiplied with 30/30

6/30(40/40) = 240/1200

12/40(30/30) = 360/1200

As we can see, 360/1200 is bigger than 240/1200, therefore 12/40 is bigger

Answer: \(\frac{12}{40}\)

Step-by-step explanation:

Hey there!

-If we were to simplify \(\frac{6}{30}\) we would be able to simplify it to \(\frac{1}{5}\).

-Multiply \(\frac{6}{30}\) by 100 and you get 20 .

-Now compare that with \(\frac{3}{10}\) which is \(\frac{12}{40}\) simplified.

-Multiply \(\frac{12}{40}\) by 100 and you get 30.

-We can now tell that \(\frac{12}{40}\) is greater than \(\frac{6}{30}\).

We can say that HK is not closed under inverses and hence is not a subgroup of G

Let G be the group of integers under addition (i.e., G = {..., -2, -1, 0, 1, 2, ...}), and let H and K be the following subgroups of G:

H = {0, ±2, ±4, ...} (the even integers)

K = {0, ±3, ±6, ...} (the multiples of 3)

Now consider the product HK, which consists of all elements of the form hk, where h is an even integer and k is a multiple of 3. Specifically:

HK = {0, ±6, ±12, ±18, ...}

Note that HK contains all the elements of H and all the elements of K, as well as additional elements that are not in either H or K. For example, 6 is in HK but not in H or K.

To show that HK is not a subgroup of G, we need to find two elements of HK whose sum is not in HK. Consider the elements 6 and 12, which are both in HK. Their sum is 18, which is also in HK (since it is a multiple of 6 and a multiple of 3). However, the difference 12 = 18 - 6 is not in HK, since it is not a multiple of either 2 or 3.

Therefore, HK is not closed under inverses and hence is not a subgroup of G

Smith working 60 hours a week and having to commute 45 minutes in one direction during peak traffic are examples of the "constraints" or "demands" of life.

Smith working 60 hours a week and having to commute 45 minutes in one direction during peak traffic are examples of the constraints or demands of life because they represent factors that limit or restrict Smith's time and energy.

The constraint of working 60 hours a week implies that Smith has a limited amount of time available for other activities and commitments. This constraint may affect his ability to engage in leisure activities, spend time with family and friends, or pursue personal interests outside of work.

Similarly, the demand of a 45-minute commute during peak traffic adds to Smith's daily responsibilities and consumes additional time and energy. This demand can contribute to stress, fatigue, and less time available for other activities.

To find the percentage, we can use the following formula:

Percentage = (Part / Whole) * 100

So, $131,701.32 is approximately 16.67% of $790,207.91.

In this case, the part is $131,701.32 and the whole is $790,207.91.

Percentage = ($131,701.32 / $790,207.91) * 100

Calculating the value:

Percentage ≈ 0.1667 * 100

Percentage ≈ 16.67%

Therefore, $131,701.32 is approximately 16.67% of $790,207.91.

Alternatively, we can calculate the percentage by dividing the part by the whole and multiplying by 100:

Percentage = ($131,701.32 / $790,207.91) * 100 ≈ 0.1667 * 100 ≈ 16.67%

So, $131,701.32 is approximately 16.67% of $790,207.91.

The HRT (Hydraulic Retention Time) of an aeration tank with a volume of 425,000 gallons (1,609,000 liters) and an influent rate of 850,000 gallons (3,218,000 liters) is 0.5 hours.

To calculate the HRT, follow these steps:

1. Identify the tank volume: 425,000 gallons (1,609,000 liters).

2. Identify the influent rate: 850,000 gallons (3,218,000 liters) per day.

3. Convert the influent rate to an hourly rate by dividing by 24 hours: (850,000 gallons / 24) = 35,416.67 gallons per hour (145,750 liters per hour).

4. Calculate the HRT by dividing the tank volume by the hourly influent rate: (425,000 gallons / 35,416.67 gallons per hour) = 0.5 hours (1,609,000 liters / 145,750 liters per hour = 0.5 hours).
