The last number of the first half is 3.5
What is Number system?A number system is defined as a system of writing to express numbers.
The set of all the 7-digit numbers that can be obtained using, for each number, all the digits 1, 2, 3,..., 7.
If you list the numbers of the set in increasing order and split the list exactly at the middle into two parts of the same size
We need to find the last number of the first half
The numbers are 7.
To split into two parts we have to divide by 2
So 7/2=3.5
Hence, the last number of the first half is 3.5

What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
The slope intercept form of a linear equation is:
y = mx + b
Where m is the slope (rate of change) and b is the y intercept.
Let us assume the line passes through the point (0, 2) and (2, 12), hence:

I have a product I’m selling for 111.55 my gross margin is 3% what is my average cost? Also what is the formula?
The average cost of your item, based on a gross margin of 3%, is $108.20.
What is the average cost?The average cost is the cost per unit.
It can be computed as the quotient of the total cost and the number of units.
What is the gross margin?The gross margin is the percentage difference between the cost of goods sold and the sales revenue.
The gross margin percentage is expressed as a quotient of the sales revenue multiplied by 100.
Selling price = $111.55
Gross margin = 3%
Selling price = 100%
Cost of goods sold = 97% (100 - 3)
Average cost (cost per unit) = Selling Price x Percentage Cost/Selling Price Percentage
$108.20 ($111.55 x 97/100)
Thus, the average cost of the product is $108.20.

The measure of m<1 is 108 degrees from the provided figure.
Line geometry involving transversalsA line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Lines are therefore one-dimensional objects, even if they can exist in spaces with two, three, or more dimensions.
From the diagram, we have the following parameters
m<2 = 72 degrees
Required parameters
The measure of angle m<1
From the figure, the sum of the interior angle is equivalent to 180 degrees, that is:
m<1 + m<2 = 180
m<1 = 180 - m<2
m<1 = 180 - 72
m<1 = 108 degrees
Hence the measure of m<1 from the given figure is 108 degrees.

If a 4 lb bag of sugar costs $2.99, what is the unit cost for a pound of sugar?
Answer: The unit cost for a pound of sugar is $0.75. This means that for every pound of sugar, it costs $0.75.
Step-by-step explanation:
To find the unit cost for a pound of sugar, we need to divide the total cost of the 4 lb bag of sugar by the weight of the bag.
Unit cost = Total cost / Weight
Total cost = $2.99
Weight = 4 lbs
Unit cost = $2.99 / 4 lbs = $0.75 per pound
So, the unit cost for a pound of sugar is $0.75. This means that for every pound of sugar, it costs $0.75.
It's worth noting that this calculation gives us the unit price of the sugar, which is the price per pound of sugar, and not the unit cost which is the total cost of production divided by the total number of units produced.
It's also worth noting that some sellers may use different units of measurement, and you should always check that you are comparing the same units when comparing prices.
Answer:
The unit cost for a pound of sugar would be $0.75.
To find the unit cost, divide the total cost by the number of pounds: $2.99 / 4 lbs = $0.75/lb.

What is an exponential function?Exponential function is a type of function of the form: f(x) = a(b)^x. It is made up of 3 main parts
a = the starting or initial value
b = the base function
x = the exponents
Considering the given problem, f(x) = a(b)ˣ
the starting, a = 370
the base = ?
the exponents = year periods
the base is calculated below
form 2012 to 2005 is 7 years hence x = 7
amount inn 2012 = amount in 2005 (b)ˣ
480 = 370 * b⁷
48/27 = b⁷
b = 1.038
this is same as 3.8% increment
The amount in 2017
from 2017 to 2005 is 12

increased by 8 percent before it was 1.62
Answer:
Not rounded:
1.62 increased by 8% of the value = 1.7496
The actual change:
1.7496 - 1.62 = 0.1296
Rounded off to max. 2 decimal places:
1.62 increased by 8% of the value ≈ 1.75
The actual change:
1.75 - 1.62 ≈ 0.13
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
8% = 8 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
8% = 8/100 = 8 ÷ 100 = 0.08
100% = 100/100 = 100 ÷ 100 = 1
The value of the percentage increase = 8% × 1.62
The new value = 1.62 + The value of the percentage increase
The new value =
1.62 + The value of the percentage increase =
1.62 + (8% × 1.62) =
1.62 + 8% × 1.62 =
(1 + 8%) × 1.62 =
(100% + 8%) × 1.62 =
108% × 1.62 =
108 ÷ 100 × 1.62 =
108 × 1.62 ÷ 100 =

Landon works in a department store selling clothing. He makes a guaranteed salary of $400 per week, but is paid a commision on top of his base salary equal to 15% of his total sales for the week. How much would Landon make in a week in which he made $1500 in sales? How much would Landon make in a week if he made xx dollars in sales?
a) In a week in which Landon made $1,500 in sales, his weekly earnings would be $625.
b) In a week in which Landon made x in sales, his weekly earnings would be $400 + 0.15x.
How are the weekly earnings determined?The weekly earnings are the sum of Landon's guaranteed or base salary per week and the sales commission he earns.
The sales commission is based on the sales Landon achieves per week and the commission rate of 15%.
The above situation implies that a percentage of the sales is paid out to Landon as a commission. Generally, sales commissions are paid to encourage increased sales.
Guaranteed salary per week = $400
Sales commission on total weekly sales = 15%
Total weekly sales = $1,500
Landon's total earnings for the week = $625 [$400 + $1,500(0.15)]
Landon's total earnings in a week he made xx dollars in sales = $400 + 0.15x
Thus, we can conclude that Landon gets 15 cents (15%) from each dollar in sales in addition to his weekly base salary of $400.

Answer:
P = 5c + 11 , c = 3
Step-by-step explanation:
(a)
the perimeter P) is the sum of the sides.
Note that the 2 sides with a ' dash' through them are congruent
summing the 4 sides
P = c + 5 + 3c - 2 + 10 - 2c + 3c - 2 ( collect like terms )
= 5c + 11
(b)
equate the expression for P from (a) to 26
5c + 11 = 26 ( subtract 11 from both sides )
5c = 15 ( divide both sides by 5 )
c = 3

The equation for Khloe's distance from her car in miles, y, as a function of the time in hours, x, is y = -3x + 11.
What is Linear Function?A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables but does not have exponents to the variables or the exponent of the variable is 1.
We have the two points of x and y.
After 1 hour, Khloe is 8 miles from her car.
When x = 1, y = 8
After 3 hours, Khloe is 2 miles from the car.
When x = 3, y = 2
Points of the linear function are (1, 8) and (3, 2)
Slope of the line = (2 - 8) / (3 - 1) = -6/2 = -3
Take a point (1, 8).
Equation of the linear function in point slope form can be written as,
y - 8 = -3(x - 1)
y - 8 = -3x + 3
y = -3x + 3 + 8
y = -3x + 11

A histogram is a graphical representation of a dataset, showing the frequency of each data point in a specific range. The x-axis shows the range of data points, and the y-axis shows the frequency of each data point. Without the data, it's impossible to draw any conclusion.
In order to draw a conclusion, we need to know the data that the histogram represents, such as the range of temperatures, the frequency of each temperature, and the number of days in the month. Based on that information, we can draw conclusions about the data provided.
