Answer 1

Answer:

1. 15

2. 6 × 7 × 4 or 6 × 4 × 7 or 7 × 4 × 6 or 7 × 6 × 4

3. (9 + 5) + 3

4. 11

5. 1

6. 0

Step-by-step explanation:

1. Additive Identity means that if you add 0 with any number, the result would always be the number itself.

2. Commutative Property of Multiplication means that no matter what order, the result would still be the same when the arithmetic operations are all ×.

3. Associative Property of Addition means that no matter where the bracket is placed or which numbers are associated with each other using a bracket, the result would still be the same.

4. Multiplicative Identity means that if you times 1 with any number, the result would always be the number itself.

5. Multiplicative Inverse means that when the denominator of the first fraction is the same as the numerator of the second fraction and the numerator of the first fraction is the same as the denominator of the second fraction, the result would always be 1.

6. If you add the positive of a number with a negative of a number, the result would always be 0.

Question 15 (5 points)
Solve |3x - 2| = |x + 1|
A) x = 3/2 or x= 1/4
B) x= 1/4
C) No solutions
D) x = 3 or x = -4

Answers

Answer:

A) x = 3/2 or x= 1/4

Step-by-step explanation:

Solve for x

|3x − 2| = |x + 1|

Rewrite the absolute value equation as four equations without absolute value bars.

3x − 2 = x + 1

3x − 2 = − (x + 1)

− (3x − 2) = x + 1

− (3x − 2) = − (x + 1)

After simplifying, there are only two unique equations to be solved.

3x − 2 = x + 1

3x − 2 = − (x + 1)

Solve 3x − 2 = x + 1 for x.

Move all terms containing x to the left side of the equation.

2x − 2 = 1

Move all terms not containing x to the right side of the equation.

2x = 3

Divide each term by 2 and simplify.

x = ------

Solve 3x − 2 = − (x + 1) for x.

Simplify − (x + 1).

3x − 2 = −x − 1

Move all terms containing x to the left side of the equation.

4x − 2 = −1

Move all terms not containing x to the right side of the equation.

4x = 1

Divide each term by 4 and simplify.

x = ------

Solve for x.

Find the greatest common factor (GCF) of 65 and 55.

Answers

The biggest common factor number is the GCF number. So the greatest common factor 55 and 65 is 5.

The greatest common factor of 65 and 55 is 5 because 5 is the highest number that is divisible by both numbers.

What is the greatest common factor?

The greatest common factor is the largest positive number which can be divided into given numbers evenly.

In mathematics, the largest positive integer that divides each of the integers is known as the greatest common divisor of two or more integers that are not all equal to zero. The greatest common divisor of two integers is x and y.

Given that the two numbers are 65 and 55. The greatest common factor is the largest number which is divided into both numbers.

65 = 13 x 5

55= 11 x 5

The greatest common factor is,

GCF = 5

Daren draws a scale model of the Statue of Liberty
that is 15 inches tall. If the Statue of Liberty is 305
feet tall, what is the scale of the model?

Answers

Answer: 1525

Step-by-step explanation:

Explanation:

One way we can do this is to divide the hight of the Statue by the model height:

305ft 1525ft

20in = 1 in

And so for every inch of the model, it represents 15.25 feet.

If you ask the first 50 females who enter a restaurant to complete a survey about their experience, who is the sample?

Answers

Answer:

the first girl

Step-by-step explanation:

because the first girl to take the survey is a sample but the rest that follows are just extras(can i get brainliest pls)

The sample in this scenario would be the first 50 females who enter the restaurant and are asked to complete a survey about their experience. These 50 females form a subset of the entire population of females entering the restaurant during that specific period.

A sample is a smaller group selected from a larger population for the purpose of gathering information or conducting research. It is often used in situations where it is impractical or impossible to survey the entire population. By surveying this sample of 50 females, the restaurant may gain insights into the experiences and opinions of their female customers.

It's important to note that the sample should ideally be randomly selected to ensure that it represents the population fairly. In this case, if the first 50 females entering the restaurant are chosen randomly, they can provide valuable feedback on their overall experience, which may help the restaurant make improvements or gain valuable insights into their customer base.

Jayson reads the first 48 pages of a 480-page book in 3 days. Marcus reads the first 50 pages of a 400-page book in 4 days. Nina reads the first 120 pages of a 600-page book in 5 days. If they continue to read at these rates, who will finish first?

Answers

Answer:

Nina will finish first.

Step-by-step explanation:

Let's calculate how many pages each person reads in one day:

Jayson ⇒ 48 pages / 3 days = 16 pages/dayMarcus ⇒ 50 pages / 4 days = 12.5 pages/dayNina ⇒ 120 pages / 5 days = 24 pages/day

Then we divide the number of pages of each book by reading speed of the respective person:

Jayson ⇒ 480 pages ÷ 16 pages/day = 30 days Marcus ⇒ 400 pages ÷ 12.5 pages/day = 32 days Nina ⇒ 600 pages ÷ 24 pages/day = 25 days

Thus Nina will take the shortest time finishing her book.
