The amount of the worker monthly tax will equals to K4,850.
What are worker income tax?An income tax refers to the tax imposed on individuals or entities in respect of the income earned by them. It is computed as the product of a tax rate times the taxable income. They may vary by type or characteristics of the taxpayer and the type of income
To calculate the worker's monthly tax, we need to determine the amount of salary that falls into each tax bracket and then calculate the tax owed for each bracket:
For a monthly salary of K30,000, the first K9,000 is tax-free, leaving K21,000 to be taxed. Of this K21,000, the first K10,000 is taxed at 15%, which gives a tax of K1,500. The next K12,000 is taxed at 25%, which gives a tax of K3,000.Finally, the remaining K-1,000 is taxed at 35%, which gives a tax of K350.The worker's monthly tax is then computed as:
= K1,500 + K3,000 + K350
= K4,850.

Jen’s phone uses a simple algorithm to count the number of strides she takes.
The algorithm looks at the phone’s accelerometer measurements, and counts a
stride each time the acceleration goes from below to above 3 g. Based on the
number of strides counted in the 20-second window shown here, and assuming
that Jen travels 140 cm per stride, what was Jen’s average walking speed, in
meters per second, over the 20-second window? Express your answer as a
decimal to the nearest hundredth.
Using the relationship between speed, distance and time, Jen's average walking speed was approximately 1.75 meters per second over the 20-second window.
What is Jen's average walking speedTo find Jen's average walking speed, we need to first find the total distance that she walked in 20 seconds. We can do this by multiplying the number of strides she took by the distance of each stride, which is given as 140 cm.
From the graph provided, we can see that Jen took 25 strides in the 20-second window. Therefore, the total distance she walked is:
distance = number of strides * distance per stride = 25 * 140 cm = 3500 cm
To convert this to meters, we divide by 100:
distance = 3500 cm / 100 = 35 meters
Finally, we can find Jen's average walking speed by dividing the total distance by the time it took her to walk it, which is 20 seconds:
average speed = distance / time = 35 meters / 20 seconds ≈ 1.75 meters per second

Answer: 1.33 m/s
Step-by-step explanation:
We need meters per second, not centimeters per second, so convert the stride of 140 cm to meters:
140 cm times 1 m/100 cm = 1.4 meters.
The number of pulses going above the dashed line for the 3 g threshold to
count as strides are 19. Therefore, a total assumed distance of $19 times 1.4 meters is covered in 20 seconds, making the average speed
19 times 1.4/20 = 19 times 0.07 = 1.33m/s.

There are 80 people in a choir.
Half of the people in the choir are women
The number of men in he choir is one quarter of the number of women
the number of children in the choir : the number of men in the choir = n:1
Work out the value of n.
You must show how you get your answer.
Answer:
We know that half of the choir members are women, which means:
Number of women = 80/2 = 40
We also know that the number of men is one-quarter of the number of women, which means:
Number of men = 40/4 = 10
Now, we're given that the ratio of children to men in the choir is n:1. Let's call the number of children in the choir "c".
So, we have:
c : 10 = n : 1
We can cross-multiply to get:
c = 10n
Since we know that the total number of people in the choir is 80, we can set up another equation:
40 (women) + 10 (men) + c (children) = 80
Substituting c = 10n, we get:
40 + 10 + 10n = 80
Simplifying the left side, we get:
50 + 10n = 80
Subtracting 50 from both sides, we get:
10n = 30
Dividing both sides by 10, we get:
n = 3
Therefore, the value of n is 3

ting is making a circular garden with a radius of 6 feet.How far across is the garden at its widest point?What is the length of edging material to the nearest hundredth needed to enclose the garden?Use 3.14
The length of edging material needed to enclose the garden is approximately 37.68 feet to the nearest hundredth.
Describe Circumference of circle?The circumference of a circle is the distance around its outer boundary, also known as its perimeter. It is one of the fundamental properties of a circle, along with its radius and diameter.
Since the garden is circular, its widest point is its diameter, which is twice the radius. Therefore, the widest point of the garden is 12 feet across.
To find the length of the edging material needed to enclose the garden, we need to find the circumference of the circle. The formula for the circumference of a circle is C = 2πr, where r is the radius and π (pi) is approximately 3.14. Substituting, r = 6 into the formula, we get:
C = 2π(6)
C = 12π
To approximate this value using 3.14, we can substitute π = 3.14 and get:
C ≈ 12(3.14)
C ≈ 37.68
Therefore, the length of edging material needed to enclose the garden is approximately 37.68 feet to the nearest hundredth.

suppose that a motorboat is moving at 40ft/s when its motor suddenly quits, and that 10 s later the boat has slowed to 20 ft/s. assume that the resistance it encounters while coasting is proportional to its velocity, so that dv/dtkv. how far will the boat coast in all?
The boat will coast a total distance of approximately 40/ln(0.5)/(-10) ft.
To solve this problem, we can use the concept of exponential decay. If we let v(t) be the velocity of the boat as a function of time t, then we can write the differential equation that describes its motion as:
dv/dt = -kv(t)
where k is the proportionality constant between resistance and velocity. We can separate variables and integrate both sides to get the velocity as a function of time:
∫(dv/dt) = -k∫(v(t))dt
v(t) = Ce^(-kt)
where C is an arbitrary constant of integration. We can use the initial condition v(0) = 40 ft/s to find C:
C = 40
So the velocity of the boat as a function of time is:
v(t) = 40e^(-kt)
We can use the condition v(10) = 20 ft/s to solve for k:
20 = 40e^(-10k)
Taking the natural logarithm of both sides:
ln(0.5) = -10k
k = ln(0.5)/(-10)
Next, we can use the velocity as a function of time to find the distance traveled by the boat:
∫(v(t))dt = ∫(40e^(-kt))dt = 40/k * (1 - e^(-kt))
Let's call the total distance traveled by the boat "D". Then we can write:
D = 40/k * (1 - e^(-kt))
We can plug in the value of k we found earlier and evaluate the expression at t = ∞:
D = 40/ln(0.5)/(-10) * (1 - e^(-∞)) = 40/ln(0.5)/(-10)

[tex]\lim_{x \to 0} \frac{1}{4} (f(x))^4 = \frac{1}{4} (\lim_{x \to 0} f(x))^4[/tex]
And we know that the thing inside the parenthesis is 4, then:
[tex]\frac{1}{4} (\lim_{x \to 0} f(x))^4 = \frac{1}{4} (4)^4 = 4^3 = 64[/tex]

Pls help
The fraction of nine times two thirds is 18/3 (option D)
What is fraction ?
A fraction is a way of representing a part of a whole or a ratio between two numbers. It consists of two numbers written one above the other and separated by a horizontal line called a fraction bar.
The number above the fraction bar is called the numerator, and it represents the part of the whole or the quantity being considered. The number below the fraction bar is called the denominator, and it represents the total number of equal parts into which the whole has been divided.
Given by the question:
Nine times two thirds can be written as:
9 × 2/3 = 18/3=6
Simplifying this fraction, we can divide both the numerator and denominator by their greatest common factor of 3, which gives:
18/3
so the correct option is D.

PLEASE SHOW ALL WORK FOR BRAINLIEST!!
The transformations from the parent cube root function to generate function g(x) are given as follows:
Vertical stretch by a factor of 4.Shift left by 2 units.Shift down by 5 units.What is a translation?A translation happens when either a figure or a function are moved horizontally or vertically.
The four translation rules for functions are given as follows:
Left a units: f(x + a).Right a units: f(x - a).Up a units: f(x) + a.Down a units: f(x) - a.For this problem, the transformations are given as follows:

eric reads an article that says 15 out of 25 adults use their computer everyday. He collects data from a random sample of adults. Out of 1,270 adults, estimate the number of adults who use their computer every day. Please show your work!
we can estimate that 762 adults in Eric's sample use their computer every day.
What is random sample?Each sample has an equal chance of being chosen as part of the sampling procedure known as random sampling. A randomly selected sample is intended to be a fair reflection of the entire population.
According to question:We can use the proportion from the article to estimate the number of adults who use their computer every day in Eric's sample.
The proportion of adults who use their computer every day from the article is:
15/25 = 0.6
This means that 60% of adults use their computer every day.
To estimate the number of adults who use their computer every day in Eric's sample, we can multiply the proportion by the sample size:
0.6 x 1,270 = 762
So we can estimate that 762 adults in Eric's sample use their computer every day.
