Answer:

n = 1/5 or 0.2

Step-by-step explanation:

Given

127/n = 635

Cross multiply

127 = n x 635

Divide both sides by 635

127/635 = n x 635/635

Divide both the numerator and denominator by 127.

We have

1/5 = n

n = 1/5 or

n = 0.2

Answer:

c = 3πcm

Step-by-step explanation:

from the question area of the circle is given to b 9/4 πcm²

circumference of the circle  in terms of π = ?

the formula for finding the Area of a circle = πr²

Since the area was given to be

(9/4)π = πr²

divide both sides by π

we have

9/4 = r²

we apply the cross multiplication rule

so we have,

4r² =  9

divide both sides by 4

r² = 9/4

r = √9/4

r = 3/2

now to find the circumference of the circle , we apply the formula for finding the circumference of a circle which is

c = 2πr

from our calculations radius r = 3/2

c = 2 ( π × 3/2)  [ 2 cancels 2]

c = 3πcm

Answer:

Jill's feet are 17 feet from the balloon.

Step-by-step explanation:

The situation is sketched in the figure attached.

The from the ground to the balloon, the distance from Jack to Jill, and the distance from the balloon to Jill's feet forms a right triangle.

The Pythagorean Theorem says the sum of the squares of the sides of the  right triangle is equal to the square of its hypotenuse [tex]x[/tex]:

[tex](8ft)^2+ (15ft)^2 = x^2[/tex]

simplifying we get

[tex]64ft^2+225ft^2=x^2[/tex]

[tex]289ft^2= x^2[/tex],

and take the square root of both sides to get:

[tex]x = \sqrt{289ft^2}[/tex]

[tex]\boxed{x = 17ft.}[/tex]

Thus, Jill's feet are 17 feet from the balloon.

Answer:

3000$

Step-by-step explanation:

900$ 30% /:30

30$ 1% /*100

3000% 100%

Mr. Clark's monthly salary is $3000, determined by dividing his food expenses of $900 by 30%, which is the portion of his salary he allocates to food.

To determine Mr. Clark's monthly salary, we use the information given that $900, which he spent on food, is 30% of his monthly salary. To find the total salary, we can set up a simple equation and solve for the salary.

Let salary be the total monthly salary of Mr. Clark. Then, 30% of the salary is equivalent to the amount spent on food:

To find the salary, divide both sides of the equation by 0.30:

Therefore, Mr. Clark's monthly salary is $3000.

This simple percentage calculation is a fundamental concept in managing a personal budget and understanding how much of one's income is dedicated to different expenses like food, housing, and savings.

Answer:

  five and eight hundredths

Step-by-step explanation:

I was taught to reserve the word "and" to mark the decimal point when the number has a fraction. The integer part is "five." The fractional part is "eight hundredths." Together, the word form might be ...

  five and eight hundredths.

__

If I were reading this to someone, including myself, I might say it as ...

  "five point oh eight".

_____

Comment on ambiguity

The reason for being particular about marking the decimal point is so you don't get into trouble with something like ...

  1000.13 . . . . . one-thousand and thirteen hundredths

which is different from ...

  1013/100 . . . . one-thousand thirteen hundredths

Some folks will pronounce 1013 as "one-thousand and thirteen." Doing so will get you in trouble in the above situation, where you have 1013/100.

Final answer:

The correct word form of 5.08 is explained as five and eight hundredths.

Explanation:

The correct word form of 5.08 is five and eight hundredths. When writing decimal numbers in words, the digit to the right of the decimal point is read as a whole number followed by the place value of the digit to the right.

In this case, 5.08 is read as five and eight hundredths.

The difference with any previous decade is much greater than the margin of error.

In statistics, the margin of error refers to half the confidence interval. It measures how much of a random sample does not fall within the confidence interval as the number of samples taken increases indefinitely. Because the margin of error depends on the level of confidence, multiple margins of error are available from the same data set.

Thus, although year after year the temperature difference is within the margin of error contemplated in the study, the truth is that the sum of several years shows differences that are not included within this margin, which proves that climate change is real and its negative effects are too.

Final answer:

Long-term data analysis shows a clear warming trend in global temperatures over the past century, significantly exceeding the margin of error. The increased frequency of warm temperatures and the scientific consensus among multiple groups validate the occurrence of anthropogenic global warming.

Explanation:

A strong counterargument to the media personality's claim that global temperatures are not rising because the yearly increase is within the margin of error is to emphasize the long-term trend and robustness of the data. Examination of global temperature trends over longer periods clearly shows that, even with margins of error considered, there has been a significant increase in global temperatures.

For instance, averaged over land and ocean, Earth's temperature over the past century has increased by approximately 0.7°C, a result that multiple groups worldwide have corroborated using various analytical methods. This consensus adds strength to the argument. When comparing temperature differences with previous decades or even centuries, the change significantly exceeds the margin of error, revealing a clear warming trend.

Moreover, the probability of warm and extreme warm temperatures has increased, while the probability of cold and extreme cold temperatures has decreased, supporting the conclusion that anthropogenic global warming is occurring and substantiating its impact beyond the bounds of statistical uncertainty.

Answer: The two point questions are 45, while the four point questions are 5.

Step-by-step explanation: We shall start by assigning letters to the unknown variables. Let the first type of question be called a and the second type of question be called b.

If the final exam is made up of 50 questions, that means

a + b = 50

Also if some questions are two points while others are four points and the total score for all of them is 110 points, then

2a + 4b = 110

(That is, we assume that a is the two point question and b is the four point question, so total score equals 110)

We now have a pair of simultaneous equations

a + b = 50 ————(1)

2a + 4b = 110 ——-(2)

From equation (1), we shall make a the subject of the equation,

hence let a = 50 - b

Substitute for the value of a in equation (2)

2a + 4b = 110

2(50 - b) + 4b = 110

100 - 2b + 4b = 110

By collecting like terms we now have

4b - 2b = 110 - 100

2b = 10

Divide both sides of the equation by 2

b = 5

Now substitute for the value of b into equation (1)

a + b = 50

a + 5 = 50

Subtract 5 from both sides of the equation

a = 45.

Therefore the two point questions are 45, while the four point questions are 5

**A quick check would show the following results ; 2(45) + 4(5) = 90 + 20 = 110.**

There are 45 questions worth 2 points each and 5 questions worth 4 points each on the 110-point final exam consisting of 50 questions.

Let's call the number of 2-point questions "x" and the number of 4-point questions "y." We can set up a system of equations to represent the information given:

1. The total number of questions is 50:

  x + y = 50

2. The total number of points is 110:

  2x + 4y = 110

Now we have a system of two equations with two variables:

1. x + y = 50

2. 2x + 4y = 110

We can solve this system of equations using either the substitution method or the elimination method. Let's use the elimination method:

First, let's multiply the first equation by 2 to make it easier to eliminate x:

1. 2(x + y) = 2(50)

2x + 2y = 100

Now we have the following system of equations:

1. 2x + 2y = 100

2. 2x + 4y = 110

Now, subtract the first equation from the second equation to eliminate x:

(2x + 4y) - (2x + 2y) = 110 - 100

This simplifies to:

2y = 10

Now, divide both sides by 2 to solve for y:

2y/2 = 10/2

y = 5

So, there are 5 questions worth 4 points each (4-point questions), and we can find the number of 2-point questions by substituting the value of y back into one of the original equations (e.g., the first equation):

x + 5 = 50

Now, subtract 5 from both sides to solve for x:

x = 50 - 5

x = 45

So, there are 45 questions worth 2 points each (2-point questions).
