Select all the expressions that have the following quotient

Final answer:

To find the weekly wage for someone working 40 hours at an hourly rate of $9.75, multiply the number of hours by the hourly rate, which equals $390.

Explanation:

The weekly wage for a person who works 40 hours at an hourly rate of $9.75 can be calculated by multiplying the number of hours worked per week by the hourly wage. Here's the calculation:

Therefore, the answer required for the weekly wage for this person is $390.

The correct order is [tex]l_n,\ m_n,\ t_n,\ r_n,\ i[/tex].

To list the values ln, rn, mn, tn and i in increasing order for any value of n, we need to understand the relationship between these variables.

The variables ln, rn, mn, and tn likely represent different measures, such as left endpoint, right endpoint, midpoint, and trapezoid point in numerical methods, while i often represents the imaginary unit iota in mathematics.

Commonly, if we assume these have increasing values when ordered, they would be listed as:

Therefore, the values in increasing order are:

[tex]l_n,\ m_n,\ t_n,\ r_n,\ i[/tex]

Answer:

The area if this figure is 35cm2

Step-by-step explanation:

The area of a circle is calculated with the formula A = πr², where pi is the mathematical constant approximately equal to 3.14159 and r represents the circle's radius. Considering significant figures is crucial for maintaining precision, as demonstrated in rounding the calculated area of a circle with radius 1.2 m to 4.5 m², based on the initial data's precision.

The area of a circle is calculated using the formula A = πr², where π (pi) is a constant approximately equal to 3.14159, and r is the radius of the circle. When calculating the area with a given radius, it's important to consider the significance of figures in your final answer. For instance, if a circle's radius is given as 1.2 meters (with two significant figures), and you calculate the area to be 4.5238934 square meters using a detailed value of pi, you need to round your final answer to maintain the precision of your initial data, resulting in an area of 4.5 m².

It's also valuable to note how ancient civilizations, like the Greeks, approximated mathematics related to circles and how such estimations have evolved into our modern understanding, where the concept of significant figures plays a critical role in ensuring accuracy across varying fields of study and applications.

Answer:

She gave out a total of 250 fliers and 99 of them were given out Wednesday. The fraction for that would be 99/250.

Step-by-step explanation:

Consider the provided information.

She gave out 85 fliers on Monday 66 fliers on Tuesday, and 99 fliers on Wednesday.

Now, calculate the total number of fliers she give:

She give 250 fliers in total.

We need to find the fraction of the fliers she give out on Wednesday.

On Wednesday she give 99 fliers and total she give 250 fliers.

99/250

Hence, she give out 99/250 fraction of fliers on Wednesday.

To divide the given polynomial by x + 2, use polynomial long division, which involves dividing the leading term, multiplying the divisor, subtracting, and repeating the process until all dividend terms are addressed.

To divide the polynomial -2x^3 - 5x^2 + 4x + 2 by x + 2, we can use the process of polynomial long division. This method is similar to long division with numbers, where we divide, multiply, subtract, bring down the next term, and repeat the process until we have gone through all terms of the dividend.

The process would look like this:

The final result would be the quotient of the division, which may or may not have a remainder.

Answer: The required function formula is,

S(t) = 2 - 0.25 t

Step-by-step explanation:

Here, the initial thickness of the ice sheet = 2 meters,

After 3 weeks, the thickness of ice sheet = 1.25 meters

Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,

⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,

Since, the ice is melting with the constant rate.

⇒ The rate of ice decreasing = 0.25 meters per week.

⇒ Total changes in t weeks = 0.25 t meters

The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.

⇒ S(t) = 2 - 0.25 t

Which is the required function's formula.

The function's formula for the ice sheet's thickness as a function of time is S(t) = -0.25t + 2.

To write the function's formula, we can use the slope-intercept form of a linear equation, which is given by the equation y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope represents the rate at which the ice thickness decreases over time. From the given information, we know that the thickness decreases by 0.75 meters over 3 weeks. Therefore, the slope is -0.75/3 = -0.25 meters per week.

Since the ice thickness is 2 meters in the beginning, the initial point on the graph is (0, 2). Using the slope-intercept form, we can write the formula for the ice sheet's thickness as a function of time as:

S(t) = -0.25t + 2

Answer:

HI!

Your spinner has 5 colors, and if you spin it, the probability of landing in each color will be the same ( because the spiner has 5 equal sections).

So for every spin, the probability on landing on each color will be 20%.

If i spin it 200 times, then the 20% of 200 is 0.2*200 = 40.

It means that if you spin it 200 times, then each colour shows 40 times theoretically. The question is: how many times should Alina expect the spinner to land on either purple or orange?

you have 40 for purple and 40 for orange, then the total times that the spinner lands on either purple or orange is 80.

Answer:

Option 3 - [tex]y=\log_{1}x[/tex] is not a logarithmic function because the base is equal to 1.

Step-by-step explanation:

To find : Which statement is true?

Solution :

As the function defined in all statement is logarithmic function.

So, The definition of logarithmic function is defined as

[tex]y=\log_bx\Rightarrow b^y=x[/tex] where, b>0 and b ≠ 1.

Now, The following statement

1) [tex]y=\log_{10}x[/tex] is not a logarithmic function because the base is greater than 0.

The statement is False as by definition, the base of a log must be greater than zero but cannot equal one.

2) [tex]y=\log_{\sqrt3}x[/tex] is not a logarithmic function because the base is a square root.

The statement is False as by definition, the base [tex]\sqrt3[/tex]  is a positive number not equal to one.

3) [tex]y=\log_{1}x[/tex] is not a logarithmic function because the base is equal to 1.

The statement is True as by definition log cannot have a base of one.

4)  [tex]y=\log_{\frac{3}{4}}x[/tex] is not a logarithmic function because the base is a fraction.

The statement is False, as 3/4 is a legitimate base, just like any other positive number other than one.

Therefore, Option 3 is true.
