a man won a lotto jackpot and he spent 2/5 on luxury cars and 1/4 on buying a house. what fraction of his lotto earnings is remaining.
The fraction of his lotto earnings that is remaining is 7/20.
What is a fraction?A fraction is a portion of a whole or, more broadly, a set of equal pieces.
Let the total amount that the man won in the lotto jackpot is x.
Now, he spent 2/5 of the jackpot on luxury cars and 1/4 on buying a house, therefore, the total spending he will do is,
[tex]\dfrac{2x}{5}+\dfrac{x}{4}[/tex]
Now, the fraction of his lotto earnings that is remaining can be written as,
[tex]x-\dfrac{2x}{5}+\dfrac{x}{4}\\\\\\=\dfrac{x}{1}-\dfrac{2x}{5}-\dfrac{x}{4}\\\\\\=\dfrac{x \times 20}{1 \times 20}-\dfrac{2x \times 4}{5 \times 4}-\dfrac{x\times 5}{4\times 5}\\\\\\=\dfrac{20x-8x-5x}{20}\\\\=\dfrac{7x}{20}[/tex]
Hence, the fraction of his lotto earnings that is remaining is 7/20.

Given f (x) = 2x^2 + 1 and g(x) = 3x – 5 , find the
following
f(g(2))
Answer:
3Step-by-step explanation:
Given functions:
f(x) = 2x² + 1g(x) = 3x - 5Solve in two steps
Find g(2)
g(2) = 3*2 - 5 = 6 - 5 = 1Find f(1)
f(1) = 2*1² + 1 = 2 + 1 = 3Find the slope determined by the following pair of points (0,8), (2, 4)
Answer:
-2
Step-by-step explanation:
We use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the points (0,8) and (2,4). This gives
[tex]\frac{4-8}{2-0}=\frac{-4}{2}=-2[/tex]
as the slope.
Hello.
Since we have two points, and we are asked to find the slope of the line, let's use the slope formula:
[tex]\mathrm{m=\displaystyle\frac{y2-y1}{x2-x1}}[/tex]
Where
m is the slope
y2 is the y-coordinate of the second point
y1 is the y-coordinate of the first point
x2 is the x-coordinate of the second point
x1 is the x-coordinate of the first point
In this case, m is unknown, y2 = 4, y1 = 8, x2=2, x1=0
Plug in the values:
[tex]\displaystyle\frac{4-8}{2-0}[/tex]
[tex]\displaystyle\frac{-4}{2} =-2[/tex]
Therefore, the slope is -2.
I hope it helps!
Have a nice day!

Answer:
132°
Step-by-step explanation:
An inscribed angle is half the measure of the arc it subtends. This means arc CB is twice the measure of inscribed angle CAB, so ...
arc CB = 2×∠CAB = 2×40° = 80°
Arc AC is twice the measure of inscribed angle ABC, so ...
arc AC = 2×∠ABC = 2×26° = 52°
The measure of central angle AOB is the same as the measure of arc AB.
x = ∠AOB = arcs AC +arc CB = 52° +80°
x = 132°

A line passes through the point , −9−3 and has a slope of 23.
Write an equation in slope-intercept form for this line.
Answer:
y=23x+204
Step-by-step explanation:
The Slope Intercept Form of the Equation of a Line is y=mx+c
where m is the Slope and c is the y-intercept
so for our problem m=Slope = 23
so the Equation will be y=23x+c
Now to find c just substitute by the given Point
-3=23*-9+c
c=204
so the Equation will be
y=23x+204

The graph shows the amount customers pay for x pounds of cheese at a deli counter. Customers pay a certain price per pound up to exactly 5 pounds. If a customer buys more than 5 pounds. then the price per pound for the entire purchase is discounted.
The amount the customers pay is an illustration of a piecewise functions
The equations of the piecewise functions are: [tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]
How to determine the equation of the piecewise function?For the first function, we have the following points.
(x,y) = (0,0) and (4,20) for 0 < x <= 5
Since the line passes through the origin, the equation of the line would be:
[tex]y = \frac{y_1}{x_1} * x[/tex]
So, we have:
[tex]y = \frac{20}{4} * x[/tex]
[tex]y = 5x[/tex] 0 < x <= 5
For the second function, we have the following points
(x,y) = (8,32) and (9,36) for x > 5
The equation of the line would be:
[tex]y = \frac{y_1-y_2}{x_1-x_2} * (x - x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{36-32}{9-8} * (x - 8) + 32[/tex]
[tex]y = 4(x - 8) + 32[/tex]
[tex]y = 4x - 32 + 32[/tex]
[tex]y = 4x[/tex] x > 5
Hence, the equations of the piecewise functions are:
[tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]

You are asked to make a list of possible 5-character passwords using the first 7 letters of the alphabet. How many distinct passwords can you make? Indicate whether this is a combination or permutation.
Using the permutation formula, as the order is important, it is found that 2520 distinct passwords can be made.
The order is important as abcde is a different password than edcba, hence the permutation formula is used.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:

Step-by-step explanation:
m = number of minutes
x(m) = 0.05m + 0.3
y(m) = 0.04m + 0.2
to find the difference between both company plans we need to subtract y from x :
0.05m + 0.3 - (0.04m + 0.2) =

The pairs of shoes is an illustration of the point estimate of the population mean.
The teenagers have 30 pairs of shoes
How to determine the number of pair of shoes?
The question is incomplete, as the dataset to determine the number of shoes is not given.

Can some one help me. Asset capital and liability please
Answer:
I hope this helps you.
Step-by-step explanation:
Assets are the economic resources belonging to a business. Assets could be money in a cash register or bank account, or items such as property, fixtures and furniture, equipment, motor vehicles, and stock or goods for resale. An important asset in businesses which sell goods or services on credit is money owed to the enterprise by customers. This asset is known as debtors.
Capital is the value of the investment in the business by the owner(s). It is that part of the business that belongs to the owner; hence it is often described as the owner’s interest.
Liabilities are the debts owed by the firm. The main types of liabilities are creditors (money owed by the business to suppliers of goods and services), bank overdrafts and bank loans.
