a man imported a machine at shillings 600,000 and sold it for shillings 1,080, does 000 find the percentage profit if he spent shillings 60,000clearing the machine from the port and futher shillings 40,000 for shipping
Answer:
The man made a profit of 63.333% from selling the machine.
Step-by-step explanation:
To find the percentage profit, you will need to first calculate the total profit the man made from selling the machine. To do this, you need to subtract the cost of importing the machine and the other costs associated with clearing and shipping it from the selling price.
Here's the calculation:
Total profit = Selling price - (Import cost + Clearing cost + Shipping cost)Substituting the values you provided, we get:Total profit = 1,080,000 - (600,000 + 60,000 + 40,000)
Total profit = 1,080,000 - 700,000Total profit = 380,000
Next, we need to divide the total profit by the import cost, and multiply the result by 100 to express the profit as a percentage. Here's the calculation:
Percentage profit = (Total profit / Import cost) * 100Substituting the values we calculated above, we get:Percentage profit = (380,000 / 600,000) * 100Percentage profit = 63.333%
Therefore, the man made a profit of 63.333% from selling the machine.

In the figure below, m ABD=100, and m<1 is four times m<2. Find m<2.
The unknown angle in the intersecting lines is as follows:
m∠2 = 20 degrees
How to find the angles when line intersect?In the figure m∠ABD is 100 degrees and m∠1 is four times m∠2. Therefore, let's find the angle m∠2.
From the diagram, the sum of angle ABC and angle CBD is equals to angle ABD.
Therefore,
m∠ABD = 100 degrees
m∠ABC = m∠2
m∠CBD = m∠1
Therefore,
let
x = m∠2
m∠1 = 4x
Hence,
100 = 4x + x
5x = 100
divide both sides by 5
x = 100 / 5
x = 20 degrees

Given that,
Imagine creating a music hall model with a scale factor of 18.
To find : How will the scale model's surface area and the real music hall's surface area compare? Considering the volume
A new concert hall using a scale factor is 18.
then,
Scale = Dimension on module / Actual dimension
Area =k²
Where

The reasonable estimate of the probability that Todd runs 5/13.
We know that,
Experimental probability = Number of favorable outcomes/total number of outcomes.
Experimental probability, also called empirical probability, is based on real experiments and rational records of what happened. A series of real-world experiments are conducted to determine the occurrence of events. Experiments with undetermined results are called random experiments. The results of such experiments are uncertain. Repeat the random experiment several times to determine its probability. Experiments are repeated a specified number of times, and each repetition is called a trial. Mathematically, the formula for experimental probability is defined as:
Probability of event P(E) =
frequency of occurrence of event / total number of trials.
According to the question:
The number of favorable outcomes are 5.
The total number of outcomes are 2 + 3 + 3 + 5 = 13.

What is an equation of the line that passes through the point (8, -7) and is parallel
to the line x + 2y = 18?
Parallel/Perpendicular Through Point
The equation of the line that passes through point (8, -7) and parallel to the line x + 2y = 18 is
y = -x/2 - 3How to find the equation of the lineA linear function consists of functions where the variables has exponents of 1.
The graph of linear functions is a straight line graph and the relationship is expressed in the form.
y = mx + c
definition of variable
y = output variable
m = slope
x = input variable
c = y intercept
x + 2y = 18
rewriting gives : y = -x/2 + 9
when the line is parallel the slope is equal hence the slope of the line is -1/2.
using the point slope formula for point (8, -7) which is
(y - y') = m(x - x')
(y + 7) = -1/2(x - 8)
y + 7 = -x/2 + 4
y = -x/2 - 3
the equation of the line is y = -x/2 - 3
