If the sum of the positive integer a and 5 is less than 12, what is the sum of all possible values of a?

Answers

Final answer:

To find the sum of all possible values of a, we subtract 5 from both sides of the inequality a + 5 < 12 and find the maximum value of a. The sum of all possible values of a is 21.

Explanation:

To find the sum of all possible values of a, we need to determine the range of possible values for a. We are given that the sum of a and 5 is less than 12. This can be expressed as a + 5 < 12. To find the maximum value of a, we subtract 5 from both sides of the inequality: a < 12 - 5 = 7. Therefore, the possible values of a are all the positive integers less than 7. To find the sum of all these values, we can use the formula for the sum of consecutive positive integers: S = (n/2)(n+1), where n is the largest integer. In this case, n = 6, so the sum of all possible values of a is (6/2)(6+1) = 21.

Final answer:

The sum of all possible values of a is 21.

Explanation:

The question states that the sum of the positive integer a and 5 is less than 12. To find the sum of all possible values of a, we need to determine the range of values that satisfy this inequality. Let's set up the inequality:

a + 5 < 12

Subtract 5 from both sides:

a < 7

So, the possible values of a are all positive integers less than 7. To find the sum of all these values, we can use the formula for the sum of an arithmetic series:

Sum = (n/2)(first term + last term)

Here, the first term is 1 and the last term is 6 (since we want integers less than 7). The number of terms, n, is 6, since there are 6 possible values of a. Plugging in these values:

Sum = (6/2)(1 + 6) = 3 * 7 = 21

So, the sum of all possible values of a is 21.

Which number is an irrational number?

A: 0.12

B: 0.1257486

C: 0.12121212

D: 0.111111

Answers

An irrational number is a number that can not be expressed as a rational number(a whole number, repeating decimal number, and a fraction that is rational.)
So 0.1257486 is the answer.

Final answer:

The irrational number in the given options is C: 0.12121212, as it repeats the sequence '12' infinitely without any pattern.

Explanation:

An irrational number is a number that cannot be expressed as a simple fraction (i.e. a ratio of two integers) and has an infinite number of non-repeating decimal places. Out of the given options, the number C: 0.12121212 is an irrational number because it repeats the sequence '12' infinitely without any pattern. The other options, A: 0.12, B: 0.1257486, and D: 0.111111, can all be expressed as fractions and have either a finite decimal representation or a repeating decimal pattern.

The shaded part represents 1/4 of the whole square, of which the area is 4/4 (1) ft^2. So, you need to find out 1/4 of 4/4. This can be done by doing 4/4 × 1/4 = 4/16 = 1/4. Therefore, the smareaof the shaded square is 1/4 ft^2.

A piece of popcorn, on average, has a volume of 1.125 inches cubed. How many pieces of popcorn will fit in a bag that has a dimension of 5 inches by 3 inches by 7 inches?

Answers

To solve for this, we need to multiply all of our dimensions by each other, and then divide that product by the volume of a piece of the average popcorn.
5 x 3 = 15;
15 x 7 = 105.

105 / 1.125 = 93.33~.

This means that 93 (whole) pieces of popcorn will fit in a bag of 105 inches.

I hope this helps!

To find out how many pieces of popcorn will fit in a bag with dimensions of 5 inches by 3 inches by 7 inches, divide the bag's volume by the average volume of a popcorn piece.

To calculate the volume of popcorn that fits in the bag:

Calculate the volume of the bag: 5 in x 3 in x 7 in = 105 in³.

Divide the bag's volume by the average volume of a piece of popcorn (105 in³ ÷ 1.125 in³ = 93.33 popcorn pieces).

Final answer:

The approximate volume of a spherical model of Earth with a radius of 3 ft is calculated using the formula V = (4/3)πr³, which results in a volume of 113.04 cubic feet when rounded to the nearest hundredth.

Explanation:

To calculate the approximate volume of a spherical model of planet Earth with a radius of 3 ft, we use the formula for the volume of a sphere, which is V = (4/3)πr³. Plugging in the values, we get V = (4/3) × 3.14 × (3 ft)³. Performing the calculation, we first cube the radius (3 ft × 3 ft × 3 ft = 27 ft³), then multiply by π (approximately 3.14), and finally multiply by 4/3. So, V = (4/3) × 3.14 × 27 ft³ = 113.04 ft³.

When we round to the nearest hundredth, the approximate volume of the model is 113.04 cubic feet.

A 1 1/2-pound piece of turkey costs $7.98. A 6-ounce package of the same sliced turkey costs $2.49. What is the difference in price per 3-ounce serving?

Answers

The difference in price per 3-ounce serving package is $0.2475.

Price Per Serving Calculation

First, we need to determine the cost per 3-ounce serving for each type of turkey packaging. Since there are 16 ounces in 1 pound, a 1 1/2-pound piece of turkey is equivalent to 24 ounces.

Cost per ounce for the 1 1/2-pound turkey: $7.98 \/ 24 ounces = $0.3325 per ounce.

Cost per 3-ounce serving for the 1 1/2-pound turkey: $0.3325 x 3 = $0.9975.

The 6-ounce package costs $2.49, so:

Cost per ounce for the 6-ounce package: $2.49 \/ 6 ounces = $0.415 per ounce.

Cost per 3-ounce serving for the 6-ounce package: $0.415 x 3 = $1.245.

The difference in price per 3-ounce serving between the two types of turkey is: $1.245 - $0.9975 = $0.2475.

Answers

m = Words per min that Justin can type
w = Words per min that Melvin can type
w = m*4

Melvin's typing rate can be expressed as 4w words per minute by multiplying Justin's rate by 4.

To determine how many words Melvin can type per minute, we need to use Justin's typing rate as a reference.

Since Justin can type w words per minute, and Melvin can type 4 times as many words as Justin, we multiply Justin's rate by 4.The expression for Melvin's typing rate is 4w words per minute.

For example, if Justin types 50 words per minute (w = 50), then Melvin would type 200 words per minute (4 * 50 = 200).

There are many questions that need to be asked when defending the guilty, but I certainly believe that one should defend the guilty. One can distinguish between their belief and job obligation under the following circumstance in which they would feel that they wont be able to provide a good defense for their client because they would not want to defend a client whose admission of guilt is contrary to their clients stated position in court. I believe that one mustnt draw the line between their belief and job obligations because then you would denying people their 8th Amendment Constitutional right which clearly states ... nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. I personally believe that you are violating your client's 6th amendment US Constitutional right which clearly states their unalienable right of having legal representation. According to the Morales law firm in San Francisco, lawyers are morally bound to defend their clients regardless of their innocence or guilt vigorously. Even if the client admits to the guilt, there's no knowing if that person actually committed the crime, they may be trying to protect someone or maybe guilty of a lesser crime. Even if I feel that it may be wrong to defend one in the case where my client is a murderer and my client has admitted to me that he/she has committed the crime. In the American Justice system, one is only accused of a crime until they are proven innocent or guilty. Based on the underlying basis of the system, I would still do my best effort to try and defend this client because I dont have to defend my client by having to insist that he/she is innocent. I can instead go the route of presenting the facts of the case through the best defense possible and leave it up to the jurors and the judge to determine the verdict (innocent or guilty). The Adversarial system in the US matches my beliefs of a person being innocent until proven guilty. The Adversarial system unlike its counterpart the Inquisitorial system allows the guilty the chance to try to prove their innocence. The Inquisitorial system does not allow for the guilty to try and defend their innocence. Since the Adversarial system in the US allows for the guilty the chance to prove their innocence I believe I am able to enter a plea of not guilty on their behalf.
