In the number 555.55 each digit is a 5 but the value of each 5 is different based on its place in the number. How does the value of the 5 in the tenths place compare to the value of the underlined digit 5

Answers

Final answer:

The value of each 5 in the number 555.55 depends on its place value. A 5 in the tenths place (representing 1/10 or 0.1) would have a much smaller value compared to a 5 in the hundreds place in the same number, due to the multiplying factor of ten for each place value.

Explanation:

In the number 555.55, each digit is indeed a 5. However, the value of each 5 changes depending on its place value. The tenths place, to the right of the decimal point, represents tenths or 1/10 (0.1).

If the underlined digit 5 is in the hundreds place, for example, it will have a value of 500. To compare, the value of the 5 in the tenths place (which is 0.5) is much smaller than the value of the 5 in the hundreds place. In fact, it's 1,000 times smaller because each move to the left in place value multiplies the digit by 10.

is the number /2500 rational or irrational? explain

Answers

2500 is rational, because it can be turned into a fraction. A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. While a irrational number can be written as a decimal, but not as a fraction, and has endless non-repeating digits to the right of the decimal point.
Ex of rational: The number 8 is a rational number because it can be written as the fraction 8/1.
Ex of irrational: π = 3.141592…
Hoped it helped! :)

Answer:

Rational

Step-by-step explanation:

If you ask about number "2500" then it is rational since 2500 can be changed in the form of p/q, where q ≠ 0. Like, 2500, 5000/2 or so on.

and if you ask about "[tex]\frac{number}{2500}[/tex]" then it is also rational  and it is terminating rational number because denominator (2500) can be converted in [tex]2^{m} *5^{n}[/tex].

Segment MN has endpoints at M(2,5) and N(-4,3). What is the midpoint of the segment?

Answers

Final answer:

To find the midpoint of segment MN, we can use the midpoint formula which states that the coordinates of the midpoint are the average of the x-coordinates and the average of the y-coordinates of the endpoints. Using this formula, we find that the midpoint of segment MN is (-1, 4).

Explanation:

To find the midpoint of the segment MN, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint are the average of the x-coordinates and the average of the y-coordinates of the endpoints.

Let's calculate the x-coordinate of the midpoint:

x-coordinate = (x1 + x2) / 2 = (2 + (-4)) / 2 = -2 / 2 = -1.

Now, let's calculate the y-coordinate of the midpoint:

y-coordinate = (y1 + y2) / 2 = (5 + 3) / 2 = 8 / 2 = 4.

Therefore, the midpoint of segment MN is (-1, 4).

Final answer:

The midpoint of the segment MN with endpoints M(2,5) and N(-4,3) is (-1, 4).

Explanation:

To find the midpoint of a segment, we can use the midpoint formula. The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints.

For segment MN with endpoints M(2,5) and N(-4,3), we can calculate the x-coordinate of the midpoint by averaging the x-coordinates:

(2 + (-4)) / 2 = -1

And we can calculate the y-coordinate of the midpoint by averaging the y-coordinates:

(5 + 3) / 2 = 4

Therefore, the midpoint of segment MN is (-1, 4).

Cindy was asked by her teacher to subtract 3 from a certain number and then divide the result by 6. Instead, she subtracted 6 and then divided the result by 3, giving an answer of 35. What would her answer have been is she had worked the problem correctly?

Answers

she subtracted 6 from a certain number and then divided the result by 3, giving her 35.

(x - 6) / 3 = 35
x - 6 = 35*3
x - 6 = 105
x = 105 + 6
x = 111

so she should have subtracted 3, then divided by 6
(111 - 3) / 6 = 108/6 = 18 <===
Taking the answer 35 multiplying it by 3 and adding 6 would give the original number chosen.
(35 × 3) - 6 = 111
Original number chosen is 111.
Now perform the correct operations.
111 - 3 = 108
108 ÷ 6 = 18
The correct answer is 18

If an experiment consists of five outcomes with p(o1) = 0.10, p(o2) = 0.20, p(o3) = 0.30, p(o4) = 0.15, then p(o5) is

Answers

Given an experiment with 5 trials, the sum of probabilities is 1.

i.e.
p(o1) + p(o2) + p(o3) + p(o4) + p(o5) = 1

0.10 + 0.20 + 0.30 + 0.15 + p(o5) = 1

0.75 + p(o5) = 1

p(o5) = 1 - 0.75 = 0.25

p(o5) = 0.25

Find all real zeros of the function y=-9x-1

Answers

For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.

or   

If y = -9x - 1, 

When y = 0 
0 = -9x - 1 
0 + 1 = -9x - 1 + 1 
1 = -9x 
1/9 = -9x/9 
1/9 = -x 
1/[9 X (-1)] = -x/-1 
- (1/9) = x 

When x = 0 
y = (-9 X 0) - 1 
y = 0 - 1 
y = - 1

a circle is centered at the point -3,2) and passes through the point (1,5). The radius of the circle is blank units. The point (-7, blank) lies on this circle

Answers

It's important that you share the complete question.  What is your goal here?  Double check to ensure that you have copied the entire problem correctly.

The general equation of a circle is x^2 + y^2 = r^2.  Here we know that the circle passes thru two points:  (-3,2) and (1,5).  Given that a third point on the circle is (-7, ? ), find the y-coordinate of this third point.


Subst. the known values (of the first point) into this equation:  (-3)^2 + (2)^2 = r^2.  Then 9 + 4 = 13 = r^2.

Let's check this.  Assuming that the equation of this specific circle is 
x^2 + y^2 = r^2 = 13, the point (1,5) must satisfy it.

(1)^2 + (5)^2 = 13 is not true, unfortunately.

(1)^2 + (5)^2 = 1 + 25 = 26 (very different from 13).

Check the original problem.  If it's different from that which you have shared, share the correct version and come back here for further help.



the shortest adult women is 24 inches tall. the tallest adult women is 92 inches tall. write and absolute value equation to represent the minimum and maximum heights

Answers

The general equation of an absolute value equation is: |x - μ|, where μ is the mean and x is a single data point. The data points given are 24 and 92.

μ = (24 + 92)/2 = 58

Let's solve for |x - μ|:
|24 - 58| = 34
|92 - 58| = 34

Therefore, the absolute value equation is:
|x - 58| = 34

Answers

Critique reasoning involves systematically evaluating arguments, identifying assumptions, assessing evidence, and providing reasoned judgments.

Critical reasoning involves analyzing arguments or claims in a systematic and logical manner to evaluate their validity, soundness, and coherence. It entails examining evidence, identifying assumptions, assessing logical consistency, and recognizing fallacies.

Critique reasoning goes beyond merely accepting or rejecting a statement; it involves providing reasoned and well-supported judgments or critiques based on evidence and logical analysis. It helps individuals develop a deeper understanding of complex issues, make informed decisions, and construct persuasive arguments.

Critique reasoning fosters intellectual independence and the ability to engage critically with diverse perspectives and ideas.
