Step-by-step explanation:

Justin is working with a microscope that magnifies objects to 175 times their actual size.

Part A

Enter a number in each box to determine the scale factor for the microscope.

= 1 : 175

Part B

The diameter of an amoeba cell is 0.30 millimeter. How big will the cell appear to Justin under the microscope?

Scale factor =

1 : 175

Diameter of the Amoeba cell = 0.3mm

1mm = 175 mm

0.3mm = x

Cross Multiply

x = 0.3 × 175

x = 52.5 mm

Part C

What is the percent increase of the area of the amoeba cell under the microscope?

Increase = 52.5 mm - 0.3mm

= 52.2 mm

Percent increase

= 52.2/52.5 × 100

= 99.4%

Step-by-step explanation:

Alternate angles are congruent.

7x - 9 = 3x + 15               {Subtract 3x form both sides}

7x - 3x -9 = 15

Answers

Answer:

m∠RSQ = 19°

Step-by-step explanation:

From the picture attached,

RT is the diameter of the a circle.

Angle subtended at the circumference by the diameter of a circle = 90°

Therefore, m∠RST = 90°

Since, m∠RSQ + m∠QST = m∠RST

m∠RSQ + 71° = 90°

m∠RSQ = 90° - 71°

             = 19°

Therefore, measure of angle RSQ is 19°.

Answer:

x > −3

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x + 2) > x

Step 1: Simplify both sides of the inequality.

3x + 6 > x

Step 2: Subtract x from both sides.

3x + 6 − x > x − x

2x + 6 > 0

Step 3: Subtract 6 from both sides.

2x + 6 − 6 > 0 − 6

2x > −6

Step 4: Divide both sides by 2.

2x / 2 > −6 / 2

x > −3

Answer:

its c cause its like method or principle of reasoning

We defined an argument as a reasoned or thoughtful process. The correct option is A.

What is an argument?

An argument is a statement or set of claims known as premises that are designed to assess the degree of truth or acceptability of another statement known as the conclusion. Arguments may be analyzed from three different perspectives: logical, dialectical, and rhetorical.

Since the act or process of arguing, reasoning, or discussing is known as an argument. Therefore, we defined an argument as a reasoned or thoughtful process.

An argument is made up of three parts: the conclusion, the premises, and the assumptions. 

THE Conclusion

The conclusion (or theses) is the point of the argument's major idea—what the author is attempting to show.

THE LOCATION

The premises are the reasoning or evidence provided by the author to justify the conclusion.

THE ASSURANCES

The assumptions support the conclusion, but unlike the premises, they are unsaid and so invisible.

They connect the premises and conclusions.

The area in square feet of a rectangular garden can be expressed as the product of the garden’s length and width, or A(x) = 3x2 +13x +14. If the width of the garden is (x + 2) feet, what is the length of the garden?

Answers

Answer:

3x+7

Step-by-step explanation:

Use long division or synthetic division. (3x^2+13x+14)/(x+2)

The length of the rectangular garden is 3x + 7

The given expression:

[tex]A = 3x^2 + 13x + 14[/tex]

the width of the garden = x + 2

let the length of the garden = y

To find:

the length of the garden

The area of the rectangular garden is calculated as;

[tex]A = y(x + 2) = 3x^2 + 13x + 14\\\\y(x + 2) = 3x^2 + 13x + 14\\\\y = \frac{3x^2 + 13x + 14}{x + 2}[/tex]

Using long division method:

                         3x + 7

                    ------------------------------

        x + 2 √ 3x² + 13x + 14

                  - (3x² + 6x)

                   -------------------------

                              7x + 14

                            - (7x + 14)

                  -------------------------------

                                0

Thus, the length of the rectangular garden, y = 3x + 7

2x + 2y = 15

Answers

Answer:

1. x= 11+-27

2.x = 7.5 + -1y

Step-by-step explanation:

1. Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

2x + 4y + -4y = 22 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 22 + -4y

2x = 22 + -4y

Divide each side by '2'.

x = 11 + -2y

Simplifying

x = 11 + -2y

2.Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

2x + 2y + -2y = 15 + -2y

Combine like terms: 2y + -2y = 0

2x + 0 = 15 + -2y

2x = 15 + -2y

Divide each side by '2'.

x = 7.5 + -1y

Simplifying

x = 7.5 + -1y

THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT​

Answers

Answer:

259.09 feet

Step-by-step explanation:

Given that,

The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.

We need to find the perimeter of the lot.

We know that,

Perimeter = sum of all sides

P = 100.52 + 15.321 + 143.250

P = 259.09 feet

So, the required perimeter of the lot is 259.09 feet.

Melanie is buying soft drink cans for the work fridge. In the shopping catalogue, she sees a 10 can
pack for $6.00 and a 24 can pack for $15.96. Which is the cheapest way for Melanie to buy the soft

Answers

If you buy the 10-pack you pay 60 cents per can ($6.00 / 10 cans = .60/can). If you buy the 24-pack, you pay more than 66 cents per can ($15.96 / 24 cans = .665/can). So it is cheaper to buy the 10-pack (60 cents vs. 66 cents for each can)

C 17. At high school A, the mean score of 50 students on a science test is 75.
At high school B, the mean score of 40 students on the same test is 80.
What is the mean score of the 90 students?

Answers

Answer:

Mean score of 90 students = 77.2

Step-by-step explanation:

Mean score of 50 students from school A = 75

Mean score of 40 students from school B = 80

We need to find mean score of the 90 students?

First we will find sum of scores of students from school A

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 75, Number of terms = 50, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\75=\frac{Sum\:of\:Terms}{50}\\Sum\:of\:Terms= 75\times 50\\Sum\:of\:Terms=3750[/tex]

So, Sum of scores for School A = 3750

Now, we will find sum of scores of students from school B

We know that: [tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}[/tex]

We have Average = 80, Number of terms = 40, We need to find Sum of terms (scores)

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\80=\frac{Sum\:of\:Terms}{40}\\Sum\:of\:Terms= 80\times 40\\Sum\:of\:Terms=3200[/tex]

So, Sum of scores for School B = 3200

Now, We will find mean score of the 90 students?

Mean score of 90 students will be:

[tex]Average=\frac{Sum\:of\:Terms}{Number\:of\:terms}\\Average=\frac{3750+3200}{90}\\Average=\frac{6950}{90}\\Average = 77.2[/tex]

So, mean score of 90 students = 77.2

Fact Pattern:Peter Protester is a fairly well-known rabble-rouser. His demonstrations have made news across the southwest, and he's been on TV several times. Now, he has had it with the current state of politics. He gathers his group of followers, and they head to downtown Phoenix to make their grievances known. Peter's followers are generally law-abiding, but there are a few in there who have been arrested after turning peaceful protest into vandalism.After about two hours of chanting and marching, Peter yells, "Alright, we've done the peaceful thing long enough. Now let's take some real action! Let's start breaking some windows now!"Phoenix Police immediately arrest him.Meantime, Rachel Reporter is in the KPHO-TV newsroom and gets a call from a police source. The source tells Rachel to take a look at the police report from Peter's arrest. Rachel heads down to the Phoenix Police Records Department and gets a copy of the police report. In it, the arresting officer writes, "This is the same Peter Protester who was convicted of domestic terrorism in 2010."Rachel believes she has a real scoop on her hands and calls for a live truck to meet her at the scene of the protest. Rachel's live report includes the news of today's arrest. She also quotes the police report, saying Peter was convicted of domestic terrorism in 2010." Rachel did not check with police or try to get ahold of Peter in jail or speak to his lawyer to verify the conviction.As it turns out, the police report was inaccurate.
